GraalVM and MicroProfile: A polyglot microservices solution


This session shows how GraalVM can help developers to integrate MicroServices and other parts of your application. By using MicroProfile, the session will also show how the same libraries can be reused across multiple services written in different languages.

Microservices need to support many programming languages, requiring both a language-agnostic network protocol and a polyglot runtime environment. Also, microservices written in one language may need to use APIs written in some other language. Using the MicroProfile conference sample architecture implemented as a polyglot solution (Java, JavaScript, Python) on GraalVM, this talk demonstrates how MicroProfile JWT, MicroProfile Metrics, MicroProfile Rest Client, MicroProfile Health Check, and more can provide architecture-level interoperability across concerns. Attendees interested in creating a polyglot solution on GraalVM compatible with MicroProfile will get a demo-heavy introduction with occasional dives into the code and leave with ready-to-run samples on GitHub.
