Motivation
Understand the JVM & Non JVM ecosystem comparing:
- Container application running with the JVM support
- Container application running with GraalVM native support
- Container application running with WASM support
And reviewing the scenarios in terms of CPU & Memory for a financial point of view in the middle term.
A microservice architecture to be evaluated with Spring Boot applications & GraalVM native capabilities
https://spring.io/microservices
Microservices are a modern approach to software whereby application code is delivered in small, manageable pieces, independent of others.
Usecase 1: Interservice communication in microservices
- HTTP Rest communications (A <- B)
- Database transactions
Usecase 2: Observability
- With Prometheus, Prometheus & Zipkin
- With Graphana, Tempo & Loki
- With Elastic stack
Usecase 3: Event Driven
- Event driven communications (A -> Event Store)
Usecase 4: Security
- Security patterns
Issues detected
Some notes from the tests using Spring Boot 3 native features.
-
muslsupport is not implemented with buildpacks -
upxsupport is not possible in OSX - Buildpacks has a different behaviour (size) between OSX & Ubuntu in terms of sizes of native apps
-
--staticis not available for OSX raised when native application A call endpoint B using http
