 Compose is the first DBaaS (Database as a Service) of its kind, geared at helping developers spend more time building their applications rather than wrestling with database provisioning and maintenance. Compose provides easy to deploy and scale data stores and services in many flavors: PostgreSQL, MongoDB, RethinkDB, Elasticsearch, Redis, etcd, and RabbitMQ.
 
 Using Compose, companies can deploy databases instantly with backups, monitoring, performance tuning, and a full-suite of management tools. Compose Enterprise brings all this to the corporate VPC (virtual private cloud).
