Ehcache was originally developed by Greg Luck, starting in 2003. In 2009, the project was purchased by Terracotta, who provides paid support. The software is still open source but some new major functionalities (Fast Restartability Consistency) are available only in commercial products like Enterprise EHCache and BigMemory, which are not open source. In March 2011, the Wikimedia Foundation announced it would use Ehcache to improve the performance of its wiki projects. However this was quickly abandoned after testing revealed problems with the approach.
