OpenStack

OpenStack is a free and open-source software platform for cloud computing, most commonly deployed as an Infrastructure-as-a-Service (IaaS) solution. It allows organizations to build and manage their own private or public clouds by controlling large pools of compute, storage, and networking resources throughout a datacenter. Users can provision these virtual resources on-demand through a web-based dashboard or programmatically via an extensive API, providing a flexible and scalable alternative to proprietary cloud providers.
