Manik Surtani introduces Infinispan, a new open source data grid that is well-suited as a cloud data store. Data grids provide highly scalable, fault-tolerant distributed caching capabilities. Infinispan improves upon existing data grids with features like consistent hashing for efficient data distribution, a JPA-like API, and client/server capabilities that make it cloud-ready. Infinispan aims to address the challenges of using traditional databases in cloud environments by providing elastic, low-latency access to large amounts of data without bottlenecks.
