Course Overview

In this course, you will learn how to develop modern cloud-native microservices with Helidon and MicroProfile.

Project Helidon is an open-source framework designed by Oracle for creating modern cloud-native microservice-based applications. Helidon was designed from scratch to be simple and fast. It’s the only microservice framework that is comprised of two versions and programming models, so-called flavors: Helidon MP and Helidon SE. Additionally, Helidon integrates with GraalVM for building native images.

Helidon MP supports the MicroProfile specification and belongs to the MicroProfile family. It’s built on Helidon SE and not derived from an application server. Thus, there’s no deployment model, no Java EE packaging, no extra stuff you don’t need. MicroProfile is a specification for building microservices architecture. MicroProfile was derived from Jakarta EE, formerly Java EE, and thus allows developers to migrate and reuse their existing Java EE code seamlessly in modern microservice applications. It delivers application portability of microservices across multiple MicroProfile vendor frameworks such as Helidon, Quarkus, Payara Micro, Open Liberty, and TomEE.
