I can't understand for difference between Apache Ignite and GridGain platform. They are equals? Or GridGain is a standard that implemented by Apache Ignite?
From the website:
Apache® Ignite™ was originally contributed to the Apache Software Foundation by GridGain Systems. The project rapidly evolved into a top level Apache project with tens of thousands of downloads per month. The GridGain Professional Edition, Enterprise Edition, and Ultimate Edition are built on Apache Ignite.
Enterprise and Ultimate editions have some "enterprise" features that are not in the open source version.
