Helidon is an open-source Java framework designed for building microservices-based applications. It provides a set of libraries and tools to simplify the development of lightweight, fast, and reactive microservices. Oracle develops Helidon and is part of the Eclipse Foundation.
There are two main components in the Helidon framework:
- Helidon SE (Simple Edition): This is a lightweight framework that is suitable for building microservices with minimal dependencies. It is designed to be simple and flexible, allowing developers to choose the components they need for their specific use case.
- Helidon MP (MicroProfile): This edition is built on top of the MicroProfile specifications, which is a set of standard APIs for developing microservices in Java. Helidon MP provides a more opinionated and feature-rich environment, making it easier for developers familiar with MicroProfile to build microservices applications.
Key features of Helidon include:
- Reactive Programming: Helidon supports reactive programming, allowing developers to build responsive and scalable applications that can handle a large number of concurrent requests.
- Containerization: Helidon applications can be easily containerized using technologies like Docker, making it straightforward to deploy and manage microservices in container orchestration platforms such as Kubernetes.
- Integration with Oracle Cloud: Helidon provides features and integrations that make it well-suited for developing applications to run on Oracle Cloud Infrastructure (OCI).
- Modularity: Helidon is designed with modularity in mind, allowing developers to pick and choose the components they need for their specific application requirements.
Overall, Helidon aims to provide a modern and lightweight alternative for Java developers building microservices-based applications, offering flexibility and simplicity in the development process.
