The rise of Helidon
Hello, Habr! I present to your attention the translation of the article by Dmitry Kornilov Helidon Takes Flight . I'm not an Oracle employee, but I found an interesting article about a new type of frameworks that is gaining popularity. So, let's go
It's a nice day today. Today we present a new Java-framework from the MicroProfile family for the implementation of micro services. Project Helidon Is a new Java framework from Oracle.
Helidon, with the Greek translation of the swallow, the type of birds, according to Wikipedia, with a streamlined streamlined body and pointed wings that provide greater maneuverability and a very efficient flight. Ideal for flying in the clouds.
Some time ago work began on what is now the project Helidon. When we entered the cloud solutions market, and the architecture of the micro services became very popular for creating cloud services, we realized that development expertise also needed to be expanded. It is possible to create microservices using Java EE, but it is better to have an infrastructure designed from the ground up to create microservices. We wanted to create a lightweight set of libraries that do not require an application server and a cloud for Java SE applications. These libraries can be used separately from each other, but, when used together, they will provide the developer with the creation of a microservice framework: the initial configuration, the security subsystem, and the web server.
There are already attempts to create standard micro service systems from MicroProfile. MicroProfile is quite popular in the Java EE /Jakarta EE community and provides development experience similar to Java EE. We like the idea and we support this initiative. Helidon implements MicroProfile 1.1. We will continue to work on the introduction of new versions of MicroProfile and intend to maintain the relevant standards of Jakarta EE in this field, since they have already been described.
localhost : 7001 /hello [/i] - the hello world application itself
localhost : 7001 /metrics - MicroProfile metrics are
localhost : 7001 /metrics /application /com.oracle.tlanger.HelloWorld.hello - The metrics of our "hello world" application
localhost : 7001 /health - the state metrics of the MicroProfile
We have many plans that are suitable for a separate article.
Our short-term goal is to illuminate and become familiar with Helidon in the Java community. We plan to talk about Helidon at some conferences. We have already scheduled four reports on Helidon on Oracle Code One 2018. We have also applied for EclipseCon Europe 2018 and will participate in the Jakarta EE /MicroProfile Community Day. Training materials, such as videos, usage examples, articles, etc. already in development and will soon be published.
As for the technical side, we are working on implementing the next version of MicroProfile, supporting GraalVM.
We are working on other cool things, but so far we can not disclose all the cards. Stay with us, we will announce new features as soon as they are ready.

Maybe it will be interesting to you:
Originally the name was J4C (Java for Cloud)
Helidon is developed by a distributed team from Prague and the USA
Helidon is already used by more than ten projects in Oracle
Some components of Helidon are still in development and will be publicly available after a while
