Arun Gupta, principal open-source technologist at Amazon wrote in his bog that the solution is a no-cost, multi-platform, production-ready distribution of the Open Java Development Kit (OpenJDK).
"Java is one of the most popular languages in use by AWS customers, and we are committed to supporting Java and keeping it free. Many of our customers have become concerned that they would have to pay for a long-term supported version of Java to run their workloads.
"As a first step, we recently re-affirmed long-term support for Java in Amazon Linux. However, our customers and the broader Java community run Java on a variety of platforms, both on and off of AWS", he wrote.
Amazon Corretto will be available with long-term support and Amazon will continue to make performance enhancements and security fixes to it, the company explained.
Amazon plans on making quarterly updates with bug fixes and patches, as well as any urgent fixes necessary outside of its schedule... Corretto 8 is available as a preview with features corresponding to those in OpenJDK 8.
General availability for the solution is planned for Q1 2019... "Corretto is designed as a drop-in replacement for all Java SE distributions unless you're using features not available in OpenJDK (e.g., Java Flight Recorder)", Gupta said.
Corretto 8 will be available at no cost until at least June of 2023. The company is working on Corretto 11, which will be available until at least August of 2024.
"Amazon has already made several contributions to OpenJDK 8 and we look forward to working closely with the OpenJDK community on future enhancements to OpenJDK 8 and 11", Gupta wrote.
"We downstream fixes made in OpenJDK, add enhancements based on our own experience and needs, and then produce Corretto builds. In case any upstreaming efforts for such patches is not successful, delayed, or inappropriate for OpenJDK project, we will provide them to our customers for as long as they add value. If an issue is solved a different way in OpenJDK, we will move to that solution as soon as it is safe to do so."
