There Is No Good Spring Boot Alternative (Unless You’re Doing One of These Three Things)

The narrative of migrating away from Spring Boot often highlights impressive improvements in performance and cost, but these cases represent specific scenarios that do not apply to most teams. The perceived issues with Spring Boot, such as slow performance or high costs, are usually due to misconfigurations or inefficient coding practices rather than flaws in the framework itself. For example, cold start problems in AWS Lambda, memory inefficiencies at scale, and the choice of Kotlin for new projects without a Spring legacy are situations where alternative frameworks like Quarkus or Micronaut might be more beneficial. However, for the majority of use cases, Spring Boot remains highly effective, especially when tuning options like virtual thread support and lazy initialization are utilized. Additionally, many teams mistakenly attribute their challenges to the framework when the real issue lies in a lack of proper observability and instrumentation, which tools like Rollbar can help address.
