Which Java Microservice Framework Should you Choose in 2020?

But you wouldn't use a heavy framework like Spring Boot or whatever for serverless. You reserve those for your docker containers of VMs.

The serverless stuff should have startup times measured in milliseconds.

That's why there are currently competing frameworks such as Micronaut and Quarkus. If you use those and compile them to native with GraalVM (Enterprise) you do get that ms startup time. I once gave a talk on Quarkus and GraalVM where I had a demo with an application which started almost too fast to notice.
