CloudStack is a cloud service from Apacheas Infrastructure as a Service (IaaS). Via this cloud service, IT service providers
can offer companies their own cloud services and hybrid cloud services. CloudStack is similar in concept
toOpenStack, but the two services are designed for different applications. Unlike OpenStack, CloudStack targets service providers and enterprises to create and run private clouds with the features of Amazon
's Elastic Compute Cloud. CloudStack allows virtual machines to be assigned to individual servers.
It also includes a networking feature, the switches to create and manage virtual networks, object and block storage systems. CloudStack allows administrators to provision and manage large networks of virtual machines with various hypervisors. For example, with VMware, Citrix's XenServer, Xen Cloud Platform, Oracle's VM Server or Microsoft's Hyper-V.
