Galder Zamarreño from Red Hat presented on Infinispan, an open source in-memory data grid platform. Infinispan can be used as a local cache, clustered cache, or as a data grid. As a data grid, it provides a highly available, distributed, and elastic data store. Infinispan also enables users to build their own data-as-a-service solutions in private clouds by virtualizing data and making it accessible in an elastic and scalable manner. Major companies use Infinispan both as a cache (e.g. for Hibernate) and as a data grid for applications requiring real-time access to distributed data.
