BOSH is an open source project which offers a tool chain for release engineering, deployment & life-cycle management of large scale distributed services. Namely, this tool chain is made of a server (the BOSH Director) and a command line tool. BOSH is typically used to package, deploy and manage cloud software. While BOSH was initially developed by VMware in 2010 to deploy Cloud Foundry PaaS, it can be used to deploy other software (Hadoop, RabbitMQ, or MySQL for instance). BOSH is particularly well-suited for managing the whole life cycle of large distributed systems.
