Background
Open banking has rapidly transformed the European financial ecosystem. Driven by regulations such as the EU’s PSD2 directive and the broader shift toward open finance, banks are required to provide secure and standardized interfaces that allow authorized third parties to access account and payment data with customer consent.
These regulatory changes have enabled entirely new types of financial services built on standardized APIs, ranging from payment initiation services to financial data aggregation and analytics platforms. For a clear explanation of how open banking works and how it affects financial services in practice, see this overview of open banking.
The growth of open banking infrastructure and API ecosystems across Europe has also been widely documented by industry monitoring platforms such as the Open Banking Tracker.
While open banking creates significant opportunities for innovation, it also introduces demanding requirements for security, compliance, scalability, and operational reliability. Financial institutions must operate complex infrastructures capable of securely handling sensitive financial data while supporting continuous development and integration with third-party services.
Challenge
Building and operating open banking platforms requires more than exposing APIs. Organizations must ensure regulatory compliance, maintain strong security controls, and operate highly reliable infrastructure capable of supporting financial-grade workloads.
At the same time, development teams must be able to deliver new features quickly while maintaining strict operational and compliance standards. Achieving this balance between innovation and stability requires mature DevOps practices, strong automation, and cloud-native infrastructure.
