The Nebula service is for both individual Microsoft development engineers and test automation systems that can often grab hundreds of virtual machines (VMs) at a time. Development engineers can access CPS via the Windows Azure Pack (WAP) self-service portal.
"Nebula offers CPS as premium reliability in contrast to the standard reliability of our existing data center hardware," the blog post said.
CPS, which was codenamed "San Diego," consists of pre-assembled racks of Dell servers running Windows Server 2012 R2, System Center 2012 R2 and Windows Azure Pack. WAP provides users with the on-premises equivalent of a number of Azure technologies, including a self-service portal, a portal for administrators to manage resource clouds, scalable Web hosting and more.
