CloudStack forms the foundation for infrastructure clouds and data center operators can quickly and easily build cloud services within their existing infrastructure to offer on-demand, elastic cloud services. 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 will allow 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 buy calling the extensive CloudStack API.

CloudStack can also be used for multiple purposes:

• Service Providers can offer virtualized hosting in an elastic cloud computing configuration
• Enterprises can stage development, testing and production in a consistent way easing the development and publishing processes for applications
• Web content providers can deploy scalable, elastic web infrastructure that can adapt to meet the demand of their readership
• Software-as-a-Service providers can offer true multi-tenant software hosting while securing each user's environments

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.

Cross Hypervisor Support

CloudStack software employs a pluggable architecture so that it works with a variety of hypervisors. A single cloud deployment can even contains multiple hypervisor implementations. Users have the complete freedom of choosing the right hypervisor for their workload. Cloud.com CloudStack software is designed to work with open source Xen and KVM hypervisors as well as enterprise-grade hypervisors such as VMware vSphere, Oracle VM or Citrix XenServer. What is somewhat unique is that with CloudStack you can run multiple hypervisors in the same cloud.

Easy-To-Use Web Interface

CloudStack provides a feature rich out-of-the-box user interface implemented on top of the CloudStack API to manage the cloud infrastructure. It is a fully AJAX based solution compatible with most of the latest internet browsers and can also be easily integrated with your existing portal. The console gives cloud administrators a view of the aggregate storage, ip pools, CPU, memory and other resources used by their cloud. Additionally, events happening within the cloud are provided chronologically.

Secure VM Console Access

From within the Cloudstack web interface users can gain secure console access to virtual machines via a SSL encrypted browser session to gather information or perform system maintenance tasks.
