Spring Developer Roadmap 2026: What You Need to Know
Spring Boot is powerful. But knowing the framework isn’t the same as understanding backend engineering.
In this video, I walk through the roadmap I believe matters for a Spring developer in 2026.
We start with data. That means real SQL — CTEs, window functions, normalization trade-offs — and understanding what ACID and BASE actually imply for system guarantees. Spring Data JPA is useful, but you still need to know what happens underneath.
Then architecture: microservices vs modular monolith, serverless, CQRS, and when HTTP, gRPC, Kafka, or WebSockets make sense. Not as buzzwords — but as design choices with trade-offs.
Security and infrastructure follow: OWASP Top 10, AuthN vs AuthZ, encryption in transit and at rest, Docker, Kubernetes, Infrastructure as Code, and observability with Micrometer, OpenTelemetry, and Grafana.
This roadmap isn’t about mastering every tool.
It’s about knowing what affects reliability in production.
