ParElastic, which had been focused on database virtualization and MySQL, has just rebranded as Tesora, and is going to focus on delivering a Database-as-a-Service (DBaaS) platform for the OpenStack cloud computing platform. In particular, the company will collaborate and contribute its deep database expertise to the OpenStack DBaaS project, Trove.
If you're unfamiliar with OpenStack Trove, database administrators use it to provision and scale database capacity in the cloud and manage multiple database management systems including MySQL, MongoDB and others. It basically provides a unified management dashboard. Trove is in use today at a number of big companies including HP, Rackspace and PayPal.
