Tesora

Tesora, Inc. operated as a key player in the Database-as-a-Service (DBaaS) market, providing solutions for enterprise clients utilizing OpenStack cloud environments. Founded in 2010 by Amrith Kumar and Ken Rugg and based in Cambridge, Massachusetts, the company initially started as ParElastic, developing proprietary technology to scale MySQL databases transparently. Responding to market preferences for open-source infrastructure solutions, the company strategically pivoted, rebranding to Tesora in early 2014 to align its focus with the OpenStack Trove project, the open-source DBaaS component of OpenStack.

The company's core business centered on its enterprise-grade DBaaS platform, which was an enhanced version of OpenStack Trove. This platform simplified the provisioning and management of a wide array of databases for cloud administrators and developers. It enabled users to deploy and manage database capacity on-demand, treating the database as just another utility service within their public, private, or hybrid cloud infrastructure. The platform provided a single, consistent interface for managing seventeen different certified databases, encompassing both SQL and NoSQL types such as Oracle, MySQL, MongoDB, Cassandra, Redis, and MariaDB. Key features included self-service provisioning, configuration management, automated backup and restore, and robust security and disaster recovery capabilities.

Tesora's business model was based on offering a commercially supported, enterprise-ready version of the open-source Trove software, a common strategy for companies built around open-source projects. This positioned them as a primary commercial support provider for Trove, attracting enterprise customers who required reliability and expert support for their cloud database operations. Over its lifetime, the company secured significant funding, raising a total of $15.5M from investors including Red Hat, General Catalyst, and Common Angels. In February 2017, Tesora was acquired by Stratoscale, an infrastructure company offering on-premises, AWS-compatible cloud regions. The acquisition was a strategic move for Stratoscale to integrate Tesora's DBaaS technology and expertise, accelerating their roadmap for delivering AWS-compatible relational and NoSQL database services within their Symphony software stack.
