Oracle will require commercial licensing for Java 8 updates from Jan 2019. Currently we are using oracle jdk and we want to switch to amazon corretto JDK. However Amazon Corretto is not available for Centos 7. We are planning to use Zulu JDK as it gives frequent software updates. Do we have to pay for using Zulu JDK? Suggest me some options for which JDK I can freely use until Amazon release Corretto .
There are various OpenJDK builds out there, with various degrees of testing, platform support, and a history of regular availability. Of these Zulu is probably the regularly available OpenJDK build that is well tested and readily available for the most platforms, and is backed by the largest JVM engineering team outside than Oracle’s. Zulu is available for pretty much any Linux distro (including Alpine), as well as Windows, MacOS, and ARM 64/32.
You don’t have to pay to use Zulu. It is free to download and use, and is 100% OSS. There are paid options (Zulu Enterprise, Zulu embedded) that add support and update SLAs, support for various embedded environments, and other considerations that are important to companies that redistribute JDKs in various forms (in devices, with their software, on the cloud, etc.), like non-contamination analysis and certification.
