[ljamen]

Environment Details

• Helidon Version: 2.0
• Helidon SE AND Helidon MP

---

Problem Description

From Issue 1515: we need to provide a general introduction to Helidon. Should include the following:

• Helidon purpose in general
• Helidon goals
• More about 2 flavors of Helidon [LJ - frameworks of Helidon include SE and MicroProfile (MP)]
• Differences between SE and MP [brief description of differences. Doc is now separated into MP and SE so details should be provided within the different sections]
  Notes:
  Helidon is an open source Java microservices framework from Oracle.
  Features a framework designed from the ground up for building microservices.
  Provides a lightweight set of libraries that doesn't require an application server and could be used in Java SE applications.
  Helidon 2.0 implements MicroProfile [version supported at release]
  Oracle Cloud integrations [what are they?]
  Two frameworks to chose from: Microframeworks (Helidon SE) and MicroProfile

• Helidon SE is the base to build lightweight reactive microservices.

• Helidon MP is an Eclipse Microprofile implementation and a runtime for microservices.
