5 Technological Foundations Every Fintech Should Master

The fintech revolution has entered a new era. The first wave — driven by design, user experience, and the “banking made simple” narrative — has evolved into a far more technical reality. Today, the ability to succeed is not determined by how sleek your app looks, but by how resilient, scalable, and intelligent your technology foundation is. 

Fintechs and digital banks across Europe, the Gulf, and Asia have already proven that the right tech strategy can make the difference between growth and gridlock. Below are five key technological areas that every emerging fintech must understand deeply — with examples of who did it right and why it worked. 

1. Data Architecture — Turning Real-Time Information into Market Speed 

In financial services, data is not just a byproduct — it’s the business itself. But data has little value unless it can be turned into real-time, actionable intelligence. 

The most successful fintechs — from Revolut in Europe to Tamara in Saudi Arabia — have built architectures that allow data to flow continuously across every layer of their systems. These are not just analytics dashboards, but event-driven ecosystems, where every transaction triggers insights and every insight drives a decision. 

In practice, this means moving beyond simple batch data warehousing toward streaming data pipelines and event processing. For instance, Revolut’s internal architecture uses Kafka-based streaming to power instant updates across millions of user wallets. This enables real-time fraud detection, personalized offers, and product testing with immediate feedback loops. A robust data architecture gives you control, speed, and foresight — the essential traits of a fintech built to last.

 

Data isn’t just the fuel of fintech — it’s the steering wheel. Without real-time intelligence, even the most innovative products drift off course.

2. Architecture Agility — Designing for Change, Not Perfection 

Every fintech begins as an experiment. But only those that can evolve their technology without collapsing under the weight of growth manage to survive. 

Early-stage fintechs often build minimum viable products quickly, but they pay a heavy price later if that MVP rests on a monolithic architecture. Once users multiply and product lines diversify, that architecture becomes a bottleneck. 

Modern success stories prove that microservices-based architecture is not just a trend, but a survival mechanism. Each product component, from customer onboarding to payments and lending, exists as an independent module that can be scaled, upgraded, or replaced without touching the rest. 

At Monzo, over 1,500 microservices handle everything from card transactions to compliance reporting. That’s how the bank could expand to millions of customers without a single day of downtime. 

Similarly, D360 Bank, which operates on INCAT’s BOS system, embraced modular architecture from day one. The flexibility of BOS’s microservice structure made it possible to deploy updates frequently while keeping system stability intact.

For fintech founders, architectural agility means designing systems not for what you need today, but for what you can’t yet predict tomorrow. 

 

In fintech, agility is the new stability. If your system can’t change quickly, it will fail quietly.

Zdzisław Grochowicz, Chief Product Officer, INCAT

 

3. Compliance-by-Design — Transforming Regulation into a Competitive Edge 

Regulation is the most underestimated innovation driver in financial technology. The most forward-thinking fintechs treat compliance not as a constraint, but as a design principle. 

Embedding compliance at the system level — rather than bolting it on later — enables speed, scalability, and trust. Zopa in the UK and Starling Bank are excellent examples: they automated AML and KYC checks as integral parts of their onboarding process. Instead of slowing growth, compliance actually accelerated it — investors saw resilience, and customers saw reliability. 

In the Middle East, the stakes are even higher. Fintechs must align not only with financial regulations, but also with religious and ethical frameworks, such as Shariah principles. D360 Bank and STC Bank, both regulated by the Saudi Central Bank (SAMA), adopted compliance-by-design models from inception. By integrating Shariah governance rules directly into their product and transaction layers, they ensure every product — from savings to financing — automatically adheres to Islamic finance standards. 

In BOS, this principle is embedded at the core level. Compliance modules and rule engines are configurable, meaning fintechs can adapt to different jurisdictions or religious frameworks without re-coding their entire stack. 

When done right, compliance-by-design doesn’t limit innovation; it legitimizes it.

Compliance is not paperwork — it’s architecture. When regulation lives inside your code, innovation becomes unstoppable. 

Piotr Hanusiak, CEO of INCAT

4. Ecosystem Connectivity — Building Growth Through Integration 

No fintech thrives in isolation. The age of open banking has proven that connectivity is the currency of growth.  Fintechs built billion-dollar valuations by turning integration itself into a product. Their APIs connect banks, merchants, and consumers — not because they create new services, but because they enable collaboration. 

For emerging fintechs, API-first development should be non-negotiable. It allows seamless integration with payment gateways, KYC providers, fraud systems, and even national regulators. More importantly, it opens the door to partnerships that accelerate distribution and customer acquisition. 

Middle Eastern fintechs understand this shift deeply. D360 Bank’s BOS-based architecture, for instance, exposes a secure open API layer that connects easily to third-party systems — from digital identity verification to telecom billing services. This openness is a key factor behind its rapid ecosystem growth in Saudi Arabia, where collaboration across sectors (banking, government, telecom) is driving digital innovation at unprecedented speed. 

Fintechs that embrace open integration don’t just scale faster — they create value networks that grow around them. 

5. Core Banking System — The Technological Heartbeat 

Last but not least: your core. 

It’s tempting for fintech founders to see the core system as a back-office engine — invisible, static, something to “deal with later.” That mistake is often fatal. The core banking system defines how fast you can launch products, how flexible your pricing can be, and how easily you can expand across markets. 

Traditional cores, built for legacy banks, are slow to change and difficult to integrate. Fintechs need the opposite: cloud-native, API-driven, event-based systems that can evolve continuously. 

This is where platforms like BOS by INCAT stand apart. BOS was designed specifically for digital banks and fintechs — built with modularity, configurability, and regulatory adaptability in mind. The system supports multi-product portfolios, subscription-based pricing, and Shariah-compliant product structures, all on a single, scalable cloud environment.

Fintechs that underestimate their core architecture eventually face costly rewrites and technical dead ends. Those that choose scalable, flexible systems early, build the freedom to innovate for years to come. 

Your core is not your engine room — it’s your brain. It defines how you think, how you grow, and how your business learns. 

Kamil Orzechowski, Business Analyst, INCAT

6. What’s next?  

The next decade of fintech innovation will not be won by the fastest-growing startups, but by the most technologically disciplined. 

To succeed, founders must master five foundations: 

• Data as a real-time feedback loop,
• Architecture that adapts faster than regulation,
• Compliance embedded as code,
• Open connectivity as a growth multiplier, and
• A core system that turns vision into execution.
   

These are not theoretical ideals — they are proven success factors for global players and regional leaders.  

At INCAT, we see this transformation every day: fintechs that invest in smart technology foundations don’t just build digital institutions— they build financial ecosystems of the future.

Can You Build a Banking Product Like a Puzzle?

In a world where agility is the name of the game, financial institutions can no longer afford to spend months — or even years —designing and launching new products from scratch. The ability to rapidly configure, test, and deploy financial products has become a critical competitive advantage. But how is this possible in a domain as complex and regulated as banking? 

Surprisingly, the answer lies in something as simple and powerful as modularity—or, to use a more relatable metaphor, building with puzzles.

What If Banking Products Were Modular? 

Imagine if instead of crafting every detail of a banking product by hand, product managers could assemble it from pre-defined, reusable components, simply just like a puzzle. In the BOS platform, that’s not a fantasy—it’s the everyday reality.

A Different Approach to Product Design 

In BOS, when defining a new product, you don’t design the entire process from scratch. Instead, you assemble it using existing functional widgets. It’s not just about setting product parameters like interest rates or maturity dates. You’re actually shaping the product’s logic and service flow by selecting the right components—such as repayment plans, disbursement methods, pricing models, customer notifications, etc. 

This approach allows banks and fintechs to: 

Launch new products in days or weeks, not months 

Ensure consistency and compliance across product lines 

Reduce development and operational costs

Quickly respond to market or regulatory changes . 

 

But how does this modularity actually work in the real world? That’s where Task Producer comes into play.

 

In BOS, when defining a new product, you don’t design the entire process from scratch.
Instead, you assemble it using existing functional widgets.  

 
The Engine Behind the Scenes: Task Producer

Think of the Task Producer as the orchestrator of your modular banking product. In BOS, products are not hardcoded—they are assembled from ready-made components. Each product line leverages a Task Producer that supplies predefined tasks and events, allowing the product to be built from modular widgets rather than the other way around.

For example: 

Opening a new loan? The Task Producer generates tasks for credit scoring, KYC verification, contract signing, and disbursement.

Updating a savings account? The Task Producer kicks off tasks like balance recalculation, interest rate application, and customer notification. 

Because the Task Producer operates based on pre-configured templates, it ensures that every instance of a product follows the correct logic and that all required actions happen at the right time.  It’s like having a conductor for an orchestra of banking microservices —each instrument (module) knows when to play its part, and the result is a harmonious, compliant, and efficient service. 

Real-Life Case: Subscription-Based Loan Product 

Let’s take a real example from a BOS client: a digital-first bank wanted to launch an innovative loan product that allowed customers to pay a monthly subscription fee instead of traditional interest. The goal was to attract a younger, digitally savvy audience looking for simple, predictable financial products. 

Instead of developing a new system, the bank used BOS to:

Select modules for loan origination, subscription-based pricing, and dynamic repayment schedules 

Configure rules for early repayment, temporary payment holidays, and auto-renewals 

Use the Task Producer to define the processing logic—triggering tasks such as monthly billing, payment validation, customer communication, and contract renewals

The entire product—from concept to launch—was live in under five weeks. 

The Benefits of Building with Puzzles

By combining modular design with the orchestration power of the Task Producer, BOS enables banks and fintechs to: 

Prototype new ideas faster than ever before 

Maintain a library of reusable business logic blocks 

Isolate changes to specific components without disrupting the entire product 

Scale products across geographies and customer segments with minimal changes

Can you build a banking product like puzzles? With BOS, the answer is a resounding yes. 

Can you build a banking product like puzzles?
With BOS, the answer is a resounding yes.

In a time when fintech challengers and evolving customer expectations demand speed, flexibility, and innovation, modularity is no longer a luxury—it’s a necessity. And platforms like BOS, with its component-driven architecture and powerful Task Producer engine, are helping banks of all sizes move from complexity to clarity.  

So the next time someone asks how you plan to innovate in banking, tell them: “We build with puzzles.”

Core Banking Migration: What Banks Should Know?

Migrating a core banking system is often perceived as a high-risk, high-complexity undertaking—and with good reason. It touches every aspect of a bank's operations, from customer data and compliance to product configuration and service delivery. Yet, in the face of rising customer expectations and digital transformation pressures, staying with outdated legacy systems is no longer a viable option.

Why Banks Migrate Their Core Systems

The decision for a bank to undertake a core banking system migration is rarely taken lightly. It is a significant undertaking involving substantial investment, time, and organizational effort.  According to a Forrester report, over 60% of global banks are currently planning or executing core transformation projects. Several compelling factors drive this strategic imperative for financial institutions worldwide:  

Mergers and Acquisitions:  When banks merge or acquire other financial institutions, the need to consolidate disparate core systems into a unified platform becomes critical for achieving operational synergies and realizing the full benefits of the integration.

High Maintenance Costs: Maintaining aging core systems can consume a significant portion of a bank's IT budget. The scarcity of skilled personnel familiar with older technologies and the increasing risk of system failures contribute to escalating operational expenses.

Digital customer expectations: Modern users expect real-time, intuitive, and personalized banking experiences. Legacy cores often lack the agility and APIs needed to deliver them.

Operational inefficiencies: Monolithic architectures and outdated codebases make it difficult to automate, optimize, and innovate. 

Regulatory pressure: Compliance with evolving standards (e.g., PSD2, Basel IV) demands more flexible and modular systems. 

Limited Product Innovation and Time-to-market demands: Launching new financial products or adapting to market trends is significantly slower with rigid legacy systems. 

Data Silos and Inefficient Processes: Older core systems often result in fragmented data across different departments and systems, leading to inefficiencies in data management, reporting, and decision-making. 

Vendor support phase-out: In some cases, vendors withdraw support for legacy core systems or force transitions to new platforms, placing banks under pressure to migrate, often with significant cost and limited strategic value.

Gartner notes that banks with legacy systems spend up to 75% of their IT budgets on maintenance, leaving little room for innovation. This stifles growth and limits competitive advantage.

Key Challenges in Core Migration 

While the benefits of core banking migration are clear, the journey is fraught with challenges. Data migration is consistently cited as the top concern in Gartner and Forrester surveys. Banks must ensure that all historical, transactional, and customer data is transferred accurately and securely, without loss, corruption, or compliance breaches. The sheer volume and sensitivity of this data elevate the complexity of the task.

Another critical challenge is managing business continuity. Core migration affects not only IT infrastructure but also day-to-day banking operations. Poorly executed transitions can result in outages, service disruptions, and customer dissatisfaction—damaging a bank’s reputation and customer trust. Skill gaps also pose a threat. Many banks lack in-house expertise in modern architectures like microservices, cloud, and event-driven systems, making it difficult to drive migration projects internally.

Additionally, institutions often find themselves locked into vendor ecosystems that are hard to exit. Legacy providers may offer limited extensibility or customization, further complicating migration efforts. According to Gartner, 30% of core transformation projects fail to deliver the expected results, often due to insufficient planning, inadequate change management, and a lack of alignment between business and IT stakeholders.

When Core Migration Succeeds 

Despite these risks, successful migrations do happen—and more frequently when they follow a pragmatic and phased strategy. Rather than replacing the entire core in one go, leading banks adopt an incremental approach, starting with non-critical modules or new product lines. This allows for testing, learning, and iterative improvement without disrupting core business functions.

Success is also tied to organizational alignment. When leadership across technology, operations, and business strategy collaborates on a unified migration roadmap, the likelihood of success improves significantly. Cloud-native platforms with modular, API-first, and event-driven architectures provide the technological flexibility needed to support gradual transformation. Just as important is the choice of partner: banks that work with vendors offering end-to-end support—from planning to go-live and beyond—are more likely to complete their migration with confidence.

The BOS Approach to Core Migration 

BOS, developed by INCAT, is designed to make core migration not only feasible but also future-proof. Unlike many traditional systems that require a “big bang” approach, BOS supports phased migration, allowing banks to transition gradually while maintaining business continuity. 

"We recognize that for many banks, replacing the core system is like open-heart surgery," says Zdzisław Grochowicz, Chief Product Officer at INCAT. "That’s why we designed BOS to be modular and interoperable. You can start small—for example, by migrating a single product line or customer segment—and expand from there." 

Key strengths of the BOS migration model include: 

Microservices-based architecture: Enables gradual replacement of legacy components without disrupting the entire system. 

Event-driven engine: Keeps legacy and new systems in sync during transition. 

API-first design with always-up-to-date migration tools: Facilitates integration with existing infrastructure, front-end applications, and third-party services, while ensuring that data migration mechanisms remain current and efficient. These tools ensure accuracy, traceability, and compliance throughout the process.

 

We recognize that for many banks, replacing the core system is like open-heart surgery. That’s why we designed BOS to be modular and interoperable. You can start small—for example, by migrating a single product line or customer segment—and expand from there.

Zdzisław Grochowicz, Chief Product Officer at INCAT

What Sets BOS Apart 

BOS stands out with its event-first architecture and high degree of customizability without coding.  

"Many platforms offer configuration, but BOS gives banks the power to define business rules and workflows dynamically, without having to touch the source code," explains Piotr Hanusiak, CEO of INCAT. "This means lower maintenance costs, shorter implementation times, and a system that truly adapts to your business." 

Another key differentiator is INCAT’s deep involvement throughout the migration process. Rather than handing over documentation and walking away, INCAT provides: 

• Dedicated migration teams with core banking and domain-specific expertise 

• Flexible deployment options (cloud, on-prem, or hybrid) 

• End-to-end support, from data mapping and sandbox testing to go-live readiness and beyond 

 

Many platforms offer configuration, but BOS gives banks the power to define business rules and workflows dynamically, without having to touch the source code. This means lower maintenance costs, shorter implementation times, and a system that truly adapts to your business. 

Piotr Hanusiak, CEO of INCAT

Lessons from the Field 

Banks that have successfully migrated to BOS often follow several best practices. Many start with greenfield initiatives — like launching a digital-only brand or testing new loan products —to validate the platform. Running BOS in parallel with legacy systems helps reduce risk and ensures smooth handover when the time comes. Prioritizing open APIs from the outset enables faster integration with payment processors, CRMs, and compliance tools.

Training and internal engagement are equally crucial. Institutions that invest early in onboarding their technical teams and aligning business stakeholders tend to experience smoother adoption and faster go-lives.

Not a matter of if, but when

Core banking migration is no longer a question of if, but when. In an era of rapid digital disruption, customer expectation, and regulatory flux, modernizing the core is essential for future viability. Yet the path to transformation must be taken with care, clarity, and the right partners.

BOS by INCAT offers more than just a next-generation core—it delivers a methodology and a team equipped to handle the entire journey from legacy to modern banking. For banks ready to make the leap, BOS provides the architecture, flexibility, and support needed to transform with confidence. The question isn’t whether your bank should migrate—it’s whether you're choosing a partner that can take you where the future is headed.

How to build a neobank from scratch? A practical guide for founders

The banking industry has undergone a radical transformation over the past decade, driven by digital innovation and shifting consumer expectations. Neobanks — fully digital financial institutions — have disrupted traditional banking by offering seamless user experiences, low fees, and innovative services tailored to modern customers.  According to market research there are over 400 neobanks worldwide as of 2024 and the global neobank market is projected to reach $2 trillion by 2030. In addition more than 20% of millennials and Gen Z prefer digital-only banking solutions. This surge presents a compelling opportunity for fintech entrepreneurs looking to establish their own neobank. But how do you build a neobank from scratch? 

Neobank? What's that?

A neobank is a digital-only financial institution that operates without physical branches. Unlike traditional banks, neobanks leverage cutting-edge technology to offer seamless, user-friendly, and cost-effective banking solutions via mobile apps and online platforms. They cater primarily to tech-savvy individuals and businesses looking for fast, flexible, and innovative banking services. Neobanks function entirely online, relying on cloud-based infrastructure and advanced APIs to provide financial services. They typically partner with licensed banks or acquire their own banking licenses to offer core banking functions like payments, loans, and savings accounts. With AI-driven analytics and automation, neobanks enhance customer experiences by personalizing services and optimizing transaction processing.

Differences between traditional banks and neobanks

Traditional banks and neobanks differ in several key aspects. Traditional banks operate physical branches where customers can conduct transactions, while neobanks are entirely digital, eliminating the need for in-person banking. Customer support in traditional banks is typically available through in-person visits or phone calls, whereas neobanks rely heavily on AI-driven chat support and automation.

In terms of fees, traditional banks often charge higher account maintenance fees, transaction fees, and other service costs, while neobanks tend to offer lower or no fees due to their cost-efficient digital infrastructure. Transaction speed is another major differentiator—traditional banks may take longer to process payments and transfers, while neobanks provide real-time transactions.

Furthermore, neobanks focus on a highly personalized banking experience using AI-driven insights and data analytics, whereas traditional banks have limited personalization due to legacy systems. These differences make neobanks particularly attractive to younger, tech-savvy customers who prioritize convenience and digital-first solutions.

Neobanks' costs

Building a neobank is a costly endeavor, with initial investments ranging from $5 million to $50 million, depending on the business model.  To give you a sense of the scale of costs involved, it's worth noting that Revolut raised approximately $800 million across multiple funding rounds before reaching profitability, N26 secured over $900 million to scale its operations and navigate regulatory challenges and Chime - one of the largest U.S. neobanks, has raised more than $2 billion to expand its product offerings and customer base.
Major cost factors include:

Licensing and Compliance – Regulatory approvals can cost millions.

Technology Development – Building and maintaining a robust banking platform requires a high budget.

Security and Fraud Prevention – Investing in cybersecurity is essential.

Marketing and Customer Acquisition – High competition demands a solid marketing strategy.

Operational Costs – Includes customer support, partnerships, and workforce expenses.

 

Neobanks are not just changing banking—they are redefining financial inclusion and customer experience in a digital-first world. 

- Piotr Hanusiak, CEO of INCAT

Benefits of neobanks

Neobanks offer several advantages over traditional banking models, making them an attractive option for both consumers and businesses:

Lower Costs – Due to the absence of physical branches, neobanks operate with lower overhead costs, enabling them to offer reduced fees or even fee-free banking.

Seamless User Experience – Their mobile-first approach ensures a smooth, intuitive, and fast banking experience.

Faster Transactions – Real-time payment processing, instant money transfers, and early paycheck deposits are some of the core advantages.

Personalized Banking Services – AI-driven analytics allow neobanks to offer tailored financial products and insights.

Financial Inclusion – Many neobanks cater to underbanked populations, offering accessible banking services to individuals and small businesses who may struggle to get accounts with traditional banks.

Integrated Financial Tools – Budgeting tools, automated savings, cryptocurrency trading, and real-time financial insights help users manage their finances more effectively.

 

Steps to building your own neobank

If you’re considering launching a neobank, here are the critical steps to follow:

 

1. Define your value proposition

The first step in building a neobank is identifying your unique value proposition (UVP). The fintech market is competitive, and differentiation is crucial. Consider the following questions: 

Who is your target audience (e.g., freelancers, SMEs, unbanked populations)? 

What problem are you solving that traditional banks fail to address? 

How will you monetize your services (subscription model, transaction fees, lending, etc.)? 

Example: Revolut started as a travel-focused banking alternative, offering multi-currency accounts with low exchange fees. Understanding your niche helps guide product development and branding.

 

2. Secure regulatory approvals 

Banking is a highly regulated industry. Before launching, you need to obtain the necessary licenses, which vary by country. The two primary routes are: 

Banking License: Required for offering full-fledged banking services, but expensive and time-consuming to acquire.

Partnership with a Licensed Bank: Many neobanks initially operate under the license of an established bank to avoid regulatory hurdles.

 

3. Choose the right core banking system

A robust core banking system (CBS) is the backbone of any neobank. The choice of CBS influences scalability, security, and flexibility. BOS is an ideal choice due to its modular architecture, API-driven approach, and cloud-native infrastructure.

Why BOS? 

Fast Deployment: BOS enables quick go-to-market strategies for neobanks.

Scalability: Handles growing transaction volumes without performance issues.

Flexibility: Supports various financial products, including current accounts, savings, lending, and subscription-based models.

Security & Compliance: Built-in compliance features for international regulations (e.g., GDPR, PSD2, AML).

Example: D360 Bank - a digital bank in Saudi Arabia, leveraged BOS to launch its services efficiently while ensuring compliance with local regulations.

 

4. Build a seamless user experience (UX/UI)

Neobanks thrive on superior user experience. Your app and web platform should be: 

Intuitive – Simple onboarding and account setup.

Fast – Instant payments, transfers, and notifications.

Secure – Two-factor authentication and biometric login.

Engaging – Gamification and rewards for user activity.

Example: Monzo gained traction by offering instant spending notifications and budget-tracking features  within its sleek mobile app.

 

5. Leverage open banking and APIs

Modern neobanks are API-first, meaning they integrate with multiple third-party services, such as: 

Identity Verification (e.g., Onfido, Jumio)

Payment Gateways (e.g., Stripe, Plaid)

Credit Scoring & Risk Management (e.g., Experian, FICO)

BOS’s API-driven architecture makes it easy to connect with these fintech solutions, allowing neobanks to build a highly customized ecosystem.

 

6. Build a Strong Security Framework

Neobanks face increasing risks of cyber fraud and financial crime. Key strategies include: 

AI-Powered Fraud Detection: Machine learning models to detect unusual transactions.

Transaction Monitoring: Real-time alerts for suspicious activities.

KYC & AML Compliance: Automate Know Your Customer (KYC) and Anti-Money Laundering (AML) checks.

 

7. Plan your customer acquisition and growth strategy

A neobank without customers is just an idea. Effective marketing strategies include: 

Referral Programs – Encourage existing users to invite others.

Content Marketing – Publish educational content on fintech trends.

Influencer & Community Engagement – Leverage social media and fintech communities.

The rise of neobanks signals a shift towards a more flexible, customer-centric banking experience. However, launching a neobank requires careful planning, compliance with regulations, and significant financial investment. With the right strategy and technology, entrepreneurs can tap into this booming industry and create a successful digital bank. If you're looking to start your neobank journey, explore how BOS can be the foundation of your success. Contact us to learn more!

The Growing Role of Managed Services in Financial IT

 

The Growing Role of Managed Services in Financial IT

by: Piotr Warszawa

The financial sector is evolving at an unprecedented pace, with banks and fintechs increasingly relying on technology to enhance or improve the productivity, flexibility, security and scalability of their operations. The rapid adoption of cloud computing, artificial intelligence, and automation has made IT infrastructure more complex than ever before. As a result, almost all financial institutions are facing operational or investment challenges to meet ever-increasing demands to streamline operations, reduce or avoid costs and improve time-to-market, etc. To address these challenges, many financial institutions are turning to Managed Services. But what exactly are Managed Services, and how do they revolutionize IT operations in the financial sector? Let’s explore this topic with real-world examples and expert insights.

 The Challenge: IT Complexity and the Need for Specialized Support

Financial institutions operate in a highly regulated and fast-changing environment. They face critical challenges such as:

• Managing IT environments efficiently without overburdening internal teams
• Achieving required or expected operational efficiency while avoiding or reducing potential costs
• Scaling operations rapidly in response to market demands

Financial institutions that already have IT departments and processes in place are trying to keep up with new IT challenges with the resources they have - but do we always have enough space, skills and knowledge, or enough time and money to acquire them?

For fintech startups and smaller banks, these challenges are even more pronounced. Many lack the in-house expertise to handle complex IT systems or the financial resources to build a dedicated IT department.

The dependency triangle

Delivered, deployed and then used IT services are the set of IT processes, technology and IT staff that create an IT Environment that works for a given business and delivers business value to that business. These three elements are: processes, technology and people, and form a kind of 'dependency triangle'. For many modern businesses, the IT Environment can be a competitive advantage and/or make the business run very efficiently and seamlessly. On the other hand, an inefficient, mismanaged, unstable IT Environment can be the cause of many business failures and high operating costs.

To better understand the concept of Managed Services, let's take a closer look at what is behind the terms: people, processes, and technology.

Processes implement business objectives and describe how business and technical (IT) services are delivered. They represent an ordered set of operations (a series of interrelated activities or tasks) designed to achieve a specific business result, solve a specific problem or lead to the achievement of a specific business or technical objective.

Technology is the sum of the IT resources (software / hardware), methods, means and activities related to the processing of information and the provision of technical services that support or perform business services, tasks and activities. Technology in the financial sector includes IT hardware (computers, servers, disk arrays and other tools) and software related to the collection, processing, transmission, storage, security and presentation of information.

People who carry out specific activities, tasks, work within specific organizational structures. A specific group of people are those who carry out activities in the field of IT - implementing or participating in business and technical processes, developing existing platforms and IT systems or IT services, implementing new ones, and carrying out maintenance and repair activities.

What Are Managed Services? A Strategic IT Approach

Managed Services involve the management of IT infrastructure, applications, and operations to a specialized third-party provider. This model allows banks and fintechs to delegate complex IT tasks while focusing on their core business activities.

Typical Managed Services include:

• Infrastructure management (servers, networks, cloud environments, Kubernetes clusters)
• Management of services (based on the SaaS, PaaS or IaaS model)
• Application maintenance and monitoring (IT platforms, middleware)
• Process automation (automating IT workflows, DevOps integration)
• Helpdesk and support services (24/7 technical assistance, troubleshooting)

Worth knowing!

Whether or not managed services qualify as IT outsourcing depends on the scope and importance of the services to the company's business. Not every managed service will be treated as outsourcing under the law. The key criterion is the degree of relevance of the service in question to the company's operations. If the services involve critical processes or the processing of sensitive data, they will be considered outsourcing and will require the application of the relevant regulations and the approval of the Financial Regulator.

By leveraging INCAT Managed Services, they:

• Reduced time-to-market
• Achieved cost savings or avoidance in IT operations
• Enhanced availability of business services through proactive monitoring

Our services included:

• Managing a dedicated Kubernetes cluster

Event-Driven Architecture: the future of core banking system design

 

Event-driven architecture (EDA) is one of the most modern and dynamic approaches in designing information systems. In the case of core systems for banks and fintechs, the application of event-driven architecture can bring numerous benefits and improvements. In this article, we will present the advantages and disadvantages of such an architecture and discuss the best practices that can be applied. 

EDA is gaining significant traction in the financial services sector. Companies within the industry are swiftly upgrading their digital infrastructure to better attract and retain customers.

Numerous financial services firms are implementing EDA to enhance both flexibility and scalability. Consider a cloud-based payments platform, where the demand for person-to-person (P2P) and person-to-merchant (P2M) payments surged dramatically, reaching over 1,500 businesses and 1.5 million users within just two weeks of its launch. The EDA framework effectively managed the burst campaigns and rapid increase in user volume. 

EDA is particularly well-suited for boosting agility and scalability, commonly appearing in microservices-based applications and other systems with decoupled components.
 

What is Event-Driven Architecture? 

Event-driven architecture revolves around the processes of creating, detecting, subscribing to, and reacting to events. An event signifies a change in the state of an object, such as selling an investment. The act of selling initiates an event. 

In contrast, traditional service-oriented architecture handles data in a static manner—by collecting and storing it—rather than treating data as dynamic. In reality, our actions are event-based, whether they are responses to requests from individuals or machines. For example, in financial services, a mortgage application transitions through various stages from submission to approval. Each of these stages constitutes an event. 

Event-driven architecture is crucial because it enables organizations to react to events in real-time. It supports simultaneous processing of activities, allowing related tasks to occur in parallel rather than sequentially. This significantly enhances the speed and flexibility of any given process.

Event-driven architecture is crucial because it enables organizations to react to events in real-time.

EDA in practice 

Just consider the process of loan origination. Numerous checks and balances are required once someone submits a loan application. One person needs to perform a credit check. Another might need to confirm the customer’s bank account balance. Someone else has to approve the application. Meanwhile, the applicant may check back in a few minutes to see if their application has been accepted. Using an EDA architecture, these processes can be managed simultaneously. Events can be created for each step, allowing them to occur concurrently. 

Another example involves onboarding a small business client. Today, the onboarding experience must be entirely digital. If it takes longer than seven minutes, the customer might abandon the process and opt for a FinTech company that offers a similar product in just three minutes. During the onboarding process, with all the questions posed to the customer, EDA enables the simultaneous pre-approval of additional products and services, such as a line of credit, a credit card, or even payroll services.

EDA and the cloud

While it's possible to implement an event-driven architecture (EDA) on local servers, the benefits are far more pronounced when utilizing the cloud. It's important to note that cloud architectures are not inherently event-driven, but the characteristics of both complement each other perfectly. 

Event-driven architectures inherently provide speed, scalability, and flexibility. These qualities align well with cloud architectures, which achieve horizontal scaling by design. Therefore, the combination of EDA and cloud computing is highly synergistic. Additionally, hosting EDA on the cloud allows for AI to monitor for irregularities and respond to multiple events simultaneously.

 

The benefits are far more pronounced when utilizing the cloud.

 

For banks, the need to quickly deliver products and services is vital to stay competitive. With event-driven architecture, even large banks burdened with legacy systems can rival online mortgage lenders, offering a wider range of products to customers more efficiently. 

EDA and distributed systems

Today, our work heavily relies on a distributed computing model, featuring distributed services and serverless designs. EDA plays a crucial role in this setup. There are various methods to construct distributed systems. We often face the choice between a request-response architecture and an event-driven model. In many cases, the request-response systems could be more effectively executed within an EDA framework. Unlike the request-response model, an EDA setup allows the system to automatically activate its nodes. This capability enables quicker and more efficient management of bandwidth spikes. In an EDA, servers automatically scale up or down based on traffic demands. Traditional architectures, on the other hand, require manual server activation. The automatic adjustment in EDA not only manages flows dynamically and without manual intervention but also proves to be more cost-effective. 

Why opt for EDA instead of just going serverless? 

With the current wave of migrations, businesses need to align their choices with their strategic goals and desired outcomes. Adopting a serverless approach can certainly boost performance, but undertaking a comprehensive re-architecture can offer even greater benefits. 

Modern architectures are transitioning towards microservices and decoupled designs. Event-Driven Architecture (EDA) is essential for achieving this. EDA provides scalability, flexibility, and the ability to quickly adapt to market changes. 

EDA in BOS System 

BOS's event-driven framework facilitates smooth integration with various systems while offering significant flexibility and scalability. The communication model in BOS employs a publish-subscribe mechanism, where events are generated by producers and received by consumers. This publish-subscribe method ensures effective and scalable interaction between the system's components. 

BOS is equipped with a powerful event processing engine capable of managing a large number of events in real-time. This engine utilizes an internal event bus for simple event management and routing. The event bus directs events to the correct components and ensures timely processing. Additionally, the event processing engine supports the filtering, transformation, and aggregation of events, enhancing its flexibility. 

The event-driven design of BOS simplifies the integration with third-party systems. This model promotes efficient data exchange and sharing between BOS and other systems, ensuring high interoperability. Furthermore, the system's APIs facilitate easy integration with additional solutions. 

 

Is EDA for your business?  

If your data processes rely heavily on sequential steps depicted in a flowchart, then EDA might not be the best fit for your needs. Additionally, if your system doesn't experience massive bottlenecks during user logins, the shopping server traffic is manageable, and manually increasing capacity by creating tickets suffices, then adopting EDA may not be essential for your operations. 

 

Examples of the use of EDA in popular fintechs 

I. Revolut 

Revolut uses an event architecture to support its global payments. EDA allows systems to scale effectively, enabling millions of transactions to be processed per second. This allows Revolut to offer fast and reliable services to its customers around the world. 

 

 

 

II. Square 

Square uses Apache Kafka to integrate its various financial services. Event architecture allows for smooth scaling and management of data from various sources, which is crucial for effective transaction handling and data analysis

 

 

 

III. PayPal 

PayPal has implemented an event architecture to increase the flexibility and scalability of its payment services. EDA enables PayPal to respond faster to market changes and better protect users against fraud by analyzing and processing events in real time. 

 

 

 

IV. Robinhood 

Robinhood uses an event architecture to provide its users with instant notifications about stock price changes. EDA enables rapid processing of market data and providing up-to-date information to investors, which is crucial for making quick investment decisions

 

 

 

V. Stripe 

Stripe uses event-driven architecture to support its payment systems, which allows for fast and efficient payment processing. EDA minimizes latency and improves user experience by ensuring seamless transaction processing
