GridGain Systems offers an in-memory computing platform designed to enhance the speed, scalability, and durability of enterprise applications. Operating primarily in the middleware market, GridGain serves a diverse range of clients including financial institutions, web-scale companies, and mobile application developers. The platform is available in three editions: Community, Enterprise, and Ultimate, catering to different levels of enterprise needs. GridGain's core product leverages in-memory data grids (IMDG) and can store data in various types of memory, from disk to the latest persistent memory technologies like Intel Optane. This flexibility allows companies to achieve in-memory speed while benefiting from the lower cost and durability of non-volatile memory. GridGain makes money through the sale of its Enterprise and Ultimate editions, which offer advanced features such as enterprise-grade security, data center replication, and specialized connectors. The Community Edition is free and includes all the capabilities of Apache Ignite, making it suitable for production deployments with regular updates and bug fixes.
