In today’s financial industry, infrastructure has swiftly transitioned from a support function into the front line of competition. As fintech challengers and traditional banks race to become more agile, resilient and scalable, investments in cloud native cores, Banking-as-a-Service (BaaS) and open APIs are no longer optional; they’re the foundation of survival and differentiation. Let’s explore why infrastructure is now a competitive edge and how market players are investing to future proof their platforms.

Cloud-Native Core Banking: Reinventing the Engine

Cloud native cores are cores which are constructed specifically to take full advantage of cloud-based computing, by the use of microservices, container orchestration (such as Kubernetes) and real time processing, as opposed to being re engineered into cloud hosted versions of legacy systems.

This type of architectural change presents flexibility, scalability and resilience beyond compare. One practical outcome: mature financial institutions leveraging cloud native data platforms report up to 25% revenue growth and 20 to 30% cost reductions compared to slower moving peers.

Major players are putting real money behind this shift. JPMorgan, for example, allocated $17 billion in 2024 to upgrade its technology stack. These will involve the migration of key core systems to the cloud, and the construction of internal platforms to accelerate the delivery of products and create operational efficiencies.

Meanwhile, Indian fintechs are making bold moves: one company invested over KES 40 billion (~$310 million) to move fully to a cloud native private cloud environment.

Banking-as-a-Service: Embedding Finance Everywhere

Banking-as-a-Service (BaaS) is no longer a niche offering, it’s the backbone of embedded finance. By exposing core banking functions like accounts or cards via APIs, non bank companies can integrate financial services seamlessly into their products.

It’s reshaping who delivers financial services and how. Incumbents and fintechs alike must embrace BaaS to remain relevant and flexible in a world where any app might need embedded financial capability.

Open APIs: The Interoperability Imperative

Cloud native fintechs originate with an API first approach, building new services by combining plug-and-play services such as payments, KYC or fraud detection and avoiding reinvention.

Scalability of API is an extremely important strategic and technical endeavor. For instance, OnePipe, a Nigerian fintech, is navigating challenges in API scalability and security, laying out best practices for resilient, high performance open API systems.

In parallel, regulators and standard setters are moving into open finance, once again strengthening the statement that, access, and interoperability are becoming key to competitiveness.

Infrastructure as Competitive Advantage

In a world where finance can be code, infrastructure isn’t merely the plumbing, it’s the battlefield. Firms with cloud native cores can pivot faster; those with BaaS offerings can monetize finance via partners; institutions with open APIs can tap new revenue streams through ecosystem participation.

Market dynamics reflect this shift. The global core banking software market, driven by demand for modern, scalable systems, is estimated at around $17.94 billion in 2025, projected to grow to $64.65 billion by 2034 at a healthy CAGR of 15.3%.

Moreover, infrastructure spending is a bet on the future. Italy’s Bank of Italy pushed domestic banks to increase technology investment, noting that stronger digital capabilities support revenue diversification and customer service, even though tech budgets have already quadrupled since 2017.

In India, the central bank is piloting in 2025 to develop an affordable, localized cloud platform to be used by financial enterprises, illustrating the fact that access to modern infrastructure is becoming a source of strategic advantage in itself.

Future Trends and Building Blocks

Three clear trends are reinforcing infrastructure’s central role:

  • First is Observability and FinOps: Operators are embedding cost performance monitoring into cloud native development lifecycles, enabling pay-per-use economics and optimizing resource allocation using machine learning tools
  • Second is Security by Design: As API rich, cloud native ecosystems proliferate, securing them is paramount. Research into blockchain based Zero Trust frameworks shows emerging models for decentralized, tamper proof access control, critical for API and core infrastructure security.
  • Third is Revenue Efficiency Tradeoffs: While new architectures offer agility, they require heavy investment and careful migration. Companies that execute well will gain a lasting edge; others risk being outpaced in innovation, efficiency and market reach.

Conclusion

Infrastructure is now the new battleground in financial services. Cloud native cores power agility, Banking-as-a-Service enables embedded finance, and open APIs unlock ecosystems. Investments affirm that firms are betting on platforms, not just products.

The message is clear: infrastructure has become strategy. Institutions that embrace modularity, scalability and security will define the future of finance. Those that delay risk becoming utilities in a market that prizes innovation above legacy. The race is on and the winners will be those who understand that in the new financial era, infrastructure is not plumbing; it is power, positioning, and permanence.
