Microsoft published two very interesting documents which assist in designing and understanding Infrastructure as a Service based on Windows Server 2012 and System Center 2012 SP1.
- Infrastructure-as-a-Service Product Line Architecture Fabric Architecture Guide (Windows Server 2012).
This 112 pages document provides specific guidance for developing fabric architectures (compute, network, storage, and virtualization layers) of an overall private cloud solution. All of the Windows Server 2012 features are discussed.
Very much recommended reading if your task is to design a Windows Server 2012 Hyper-V infrastructure.
- Infrastructure-as-a-Service Product Line Architecture Fabric Management Architecture Guide (System Center 2012)
Fabric management is the concept of treating discrete capacity pools of servers, storage, and networks as a single fabric. The fabric is then subdivided into capacity clouds, or resource pools, that carry characteristics like delegation of access and administration, SLAs, and cost metering. Fabric management allows centralizing and automating complex management functions that can be carried out in a highly standardized, repeatable fashion to increase availability and lower operational costs.
This document discusses sizing, databases used for the various System Center components, requirements like vCPU, RAM and storage for System Center components, ITIL and MOF. It also describes at a functional level features of System Center.
The document also has a picture showing all System Center connections.
The goal of the Infrastructure-as-a-Service (IaaS) product line architecture (PLA) is to help organizations develop and implement private cloud infrastructures quickly while reducing complexity and risk. The IaaS PLA provides a reference architecture that combines Microsoft software, consolidated guidance, and validated configurations with partner technology such as compute, network, and storage architectures, in addition to value-added software components.
The private cloud model provides much of the efficiency and agility of cloud computing, with the increased control and customization that are achieved through dedicated private resources. By implementing private cloud configurations that align to the IaaS PLA, Microsoft and its hardware partners can help provide organizations the control and the flexibility that are required to reap the potential benefits of the private cloud.
The IaaS PLA utilizes the core capabilities of the Windows Server operating system, Hyper-V, and System Center to deliver a private cloud infrastructure as a service offering. These are also key software components that are used for every reference implementation.
