Open Liberty & MicroProfile Fundamentals (OLMPF)


Course Overview

In this course, you will learn the fundamentals of how to develop modern cloud-native microservices with Open Liberty and MicroProfile.

Open Liberty is an application server designed by IBM for the cloud. It’s small, lightweight, open, and designed for building fast and efficient cloud-native Java microservices. It’s derivated by IBM WebSphere and thus, supports the full MicroProfile and Jakarta EE APIs and is compostable, meaning that you can use only the features that you need, keeping the server lightweight, which is great for microservices. It also deploys to every major cloud platform, including Docker, Kubernetes, and Cloud Foundry.

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 Open Liberty, Helidon, Quarkus, Payara Micro, and TomEE.
