Case study / Modernization
Legacy to future-ready
A mission-critical estate of legacy systems needed a new technical and operating foundation. The work covered the systems, the infrastructure and the organization supporting them.
01 / The context
The challenge.
- Stateful architectures limited horizontal scaling.
- Monolithic systems needed to be separated into smaller services.
- Poor documentation and a skills gap complicated the move to newer technology.
02 / The work
DoHu's contribution.
- Evaluated the existing estate for bottlenecks and scalability constraints.
- Designed and deployed new infrastructure and planned the move to a dedicated subsidiary.
- Covered architecture, development, QA, operations and infrastructure.
- Addressed identity management with Keycloak and supported the team through training.
03 / The outcome
What changed.
- Infrastructure capable of supporting newer technology and later software development.
- Systems able to handle larger data volumes.
- Microservices that simplify maintenance and subsequent development.
