The software development landscape for the Sparkassen Finance Group covers 50 million clients and requires highly scalable and secure solutions.
A core architectural challenge is integrating emerging technologies like AI while modernizing decades of legacy systems from mainframes to the PC era.
The new architecture uses a multi-channel approach with standardized components, like Lego bricks, built on Spring Boot and Spring Cloud for flexibility.
A big bang migration is too risky, so the transformation is built into the architecture itself, prioritizing interoperability and backward compatibility.
Driving architectural change across a large organization requires a gradual, project-by-project strategy and constant communication with development teams.
Improving developer experience focuses on three key areas: maximizing productivity, building a strong community, and empowering developers to shape the future.
Gaining management support for developer experience initiatives requires framing the benefits as a win-win-win for developers, customers, and the company.
A developer portal built on Backstage, along with hackathons and an inner source policy, provides practical ways to improve daily workflows and collaboration.
Successful modernization requires a gradual approach, using pilot projects as ambassadors for change, and engaging with developers early in the process.
