GridGain provides an open source computational grid framework that enables Java developers to improve general performance of processing intensive applications by splitting and parallelizing the workload. With GridGain, developers can achieve better overall throughput, better scalability and availability of services.
GigaSpaces XAP provides a single platform for scaling-out the data, messaging and business logic of an application. By integrating the two products, GridGain customers can enjoy a highly-scalable grid computing platform for both computational and data-intensive applications. For maximum performance, GigaSpaces allows GridGain to run computational tasks in the same physical machine in which the relevant data resides in memory.
