In early 2017, Stratoscale acquired Tesora, database as a service (DBaaS) provider that offered eenterprise customers a robust platform (which is based on OpenStack Trove) to provision and manage both SQL and NoSQL databases. The platform provided support for the following popular databases on a self-service basis.
Oracle Database is a widely used Relational Database Management System. Commercially licensed by Oracle Corporation as Enterprise Edition, Standard Edition and Standard Edition One, Oracle Database is an object-relational database management system with multi-tenant architecture and in-memory data processing.
MySQL is a popular open source relational database that offered under two different editions: the open source Community Server and proprietary Enterprise Server. The Enterprise Server is differentiated by a series of proprietary extensions which install as server plugins, but otherwise shares the version numbering system and is built from the same code base.
Apache Cassandra is an open source database, providing powerful support for clusters spanning multiple data centers. Cassandra was originally developed at Facebook, later released as open source and eventually became an Apache Incubator Project.
PostgreSQL is an open source object-relational database management system (ORDBMS) based on the object relational DBMS Postgres. PostgreSQL strongly conforms to the ANSI-SQL:2008 standard and is ACID-compliant. PostgreSQL evolved from the Ingres project at the University of California, Berkeley, and the name Postgres is contracted from “post-Ingres.” It is free and open source software released under the terms of the PostgreSQL License
Redis is an open source, BSD licensed, advanced key-value cache and store database. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets, sorted sets, bitmaps and hyperloglogs. Redis is considered a NoSQL Database Management System (DBMS), a type which many consider to be the future of databases.
