Over the years, the microservice architecture has been adopted in conjunction with Spring Boot. But recently, we are introducing a rise in microframework like Micronaut and Quarkus, which innovate or build microservices by providing low memory footprint, fast startup, non-locking and other important features. Both frameworks prove booting in milliseconds and memory consumption in megabytes, but how do they do this magic? Here, this talk demystifies this magic, bringing concepts such as AOT (Ahead Of Time Compilation), Just In Time Compilation (JIT), GraalVM and Native applications.
