OpenStack is a freely available set of cloud computing services that allow you to create both private and public cloud environments. It provides tools for automating the management of compute, storage, and networking resources in a data center. OpenStack can be used to create private clouds for internal development environments or small-scale production use. It also enables the option of hosted private clouds, where an external partner runs OpenStack on your behalf. Public clouds operated by various companies use OpenStack as their underlying platform. The key benefits of OpenStack include keeping sensitive data private by hosting it yourself or with a trusted partner, and designing interoperability between private and public cloud resources. The OpenStack community includes anyone who wants to help develop its open source cloud technologies and share information
