title: Apache CloudStack: Open Source Cloud Computing —

Understanding Apache CloudStack

Apache CloudStack is open source software that forms the foundation for infrastructure clouds. Data center operators can quickly and easily build cloud services within their existing infrastructure to offer on-demand, elastic cloud services. Enterprises can use CloudStack to take on hybrid workloads, making it easier to manage legacy workloads while spinning up workloads that take advantage of the cloud model.

CloudStack users can take full advantage of cloud computing to deliver higher efficiency, limitless scale and faster deployment of new services and systems to the end-user. CloudStack allows user to coordinate virtualized servers, networking and network storage to provide infrastructure-as-a-service (IaaS) just like hosting providers – but on their own hardware.

CloudStack is an open source cloud operating system which delivers public cloud computing similar to Amazon EC2 but using your own hardware. CloudStack provides orchestration of your virtualized resources into one homogeneous environment where you can delegate the creation to users of the virtual machines using the self-service CloudStack portal.

CloudStack provides powerful features for enabling a secure multi-tenant cloud computing environment. With one click virtual servers can be deployed from a pre-defined template. Virtualized instances can be shutdown, paused and restarted via the web interface, the command line or by calling the extensive CloudStack API.

CloudStack can be used for multiple purposes:

All these capabilities are a result of years of development and collaboration by the Cloudstack development team with cloud computing users to deploy some of the largest, most scalable private and public cloud computing environments in the world.
