While Spring Boot, with its vast ecosystem and wide adoption, has long been the go-to for many developers, there’s a new challenger on the block. Micronaut, tailored specifically for microservices, boasts a design that minimizes memory footprint and optimizes startup time, among other advantages. As the digital landscape pushes for more efficiency and scalability in applications, it’s essential to choose the right tool for the job. In this article, we’ll delve into a comparison, highlighting why Micronaut might be a better choice for modern microservices development..

What’s happend when you run a Spring Boot application?

Spring is impressive and provides a plethora of features, making the job easier for Java developers. However, it carries out many of these operations at runtime. During startup, the framework scans the bytecode of all the beans, components, and annotations we use in the application. From this, it generates metadata to load into memory, which dictates how it will behave during dependency injection.
