Armeria
Your go-to microservice framework for any situation
...Let's embrace the reality, we almost always have to deal with more than one protocol. It was once Thrift, today it's gRPC, and REST never gets old. At the same time, you sometimes have to handle health check requests from a load balancer or even serve some static files. Armeria is capable of running services using different protocols, all on a single port. No need for any proxies or sidecars. Enjoy the reduced complexity and points of failure, even when migrating between protocols!
