Infinispan narrows the gap between open source and commercial data caches

The goal of the talk was to provide a technical overview of both products and outline Infinispan's road-map. Infinispan is the successor to the open-source JBoss Cache. JBoss Cache was originally targeted at simple web page caching and Infinispan builds on this to take it into the Cloud paradigm.

Well, over the past few years I have worked on projects that have used commercial distributed caching (aka data grid) technologies such as GemFire, GigaSpaces XAP or Oracle Coherence . These projects required more functionality than is currently provided by open-source solutions such as memcached or EHCache.
