2. Daniel Castillo Java Developer https://www.mrpato.dev
3. Agenda • History & Challenges • Features • Demo • Next steps • Resources • Questions
4. History & Challenges • Serverless and the next generation of Microservices • Containers and Java requires a special memory management • Reduction in resources consumption • Usage of a “deprecated” stack (Netflix MS Stack)
5. History & Challenges • Mostly all the dependencies are calculated in runtime! • WAY TOO MUCH MEMORY !!! • And don’t get me started talking on the size of the classpath!!! • A fatter classpath, a slower start up time! 5
8. Features • Dependency Injection & IoC (JSR 330) • Minimal usage of reflection • Reduce memory footprint • CLI Integration • Polyglot (Java, Kotlin & Groovy) • GraalVM Support
9. Features • HTTP Declarative Client • Unit & Integration Tests made easy! • Minimal use of proxies • Spring compatible (Yes, you can use Spring libraries!) • AOT Repositories (Micronaut Data)
10. DEMO 10
11. Next Steps • Cloud Native Integration • Modules (gRPC, Kafka, Consul, Flyway, etc) • AWS Lambdas • Micronaut Data
