Rackspace Private Cloud Powered By Microsoft helps you realize your data center goals by delivering enterprise-class capabilities, including best-in-class management of your Microsoft Windows Server infrastructure and first-party Microsoft workloads. It combines Microsoft software, consolidated guidance, and best-practice architecture with Rackspaceā€™s experience providing Fanatical SupportĀ® and hosting solutions for compute, network, and storage architectures.

Rackspace worked with Microsoft to design a cloud that complies with product line architecture (PLA) to help you develop and implement private cloud infrastructures quickly while reducing complexity and risk.

The Microsoft Private Cloud PLA uses the core capabilities of the Microsoft Windows Server operating system, Hyper-V, and System Center to deliver a private cloud infrastructure as a service offering.

The following are software features and components used for every implementation Rackspace hosts.

Cloud Platform Base Cloud

Base Cloud is a basic System Center 2012 R2 plus Windows Azure Pack that allows for the minimum compliant Cloud Platform. It is composed of the following applications and roles:

Application or role VM Quantity Software suite vCPU vRAM vDisk

The minimum system requirements to run the Base Cloud components are 52 vCPU, 128 GB of RAM, and 2.3 TB of storage. The Base Cloud workload is split across two physical host servers that are configured in a failover cluster.

Additional Cloud Platform components

In addition to the Base Cloud offering, you can use three optional add-on services to enhance your Microsoft Cloud Platform at Rackspace. You can deploy one, two, or all three of these services on your Microsoft Cloud Platform. If you add any optional services, the minimum required compute and storage must account for the additional compute and storage loads.

Web Sites Cloud

Web Sites Cloud is a service that helps you provide a high-density, scalable, shared web hosting platform for ASP.NET, PHP, and Node.js web applications. The Web Sites Cloud service includes a customizable web application gallery of open source web applications that integrate with source control systems for custom-developed websites and applications.

With Microsoft SQL Server and MySQL Server, you can create the ideal environment to leverage a database as a service (DBaaS) for your company, which brings your company into the cloud era while maintaining private cloud security. You can add one or more Microsoft SQL Servers or MySQL Server instances for tenants to deploy and use. Tenants use these databases with the Web Sites Cloud service.
