Infrastructure-as-a-Service Product Line Architecture Fabric Architecture Guide

“The scope of this document is to provide customers with the necessary guidance to develop solutions for a Microsoft private cloud infrastructure in accordance with the IaaS PLA patterns that are identified for use with the Windows Server 2012 operating system. This document provides specific guidance for developing fabric architectures (compute, network, storage, and virtualization layers) of an overall private cloud solution.”

Designing Your Cloud Infrastructure

leave a comment »

This Design Guide is focused on the design of the cloud infrastructure and the components that make up a cloud infrastructure. It does not provide information on how build a complete private cloud, public cloud, or hosted cloud infrastructure as a service (IaaS), platform as a service (PaaS), or software as a service (SaaS) solution. The cloud infrastructure contains the building blocks on which any Windows Server 2012 cloud service or delivery model is built.

This document is comprised of the following sections:

  • Cloud Infrastructure Technical Overview. This section provides a short overview of cloud computing and the requirements of a cloud infrastructure.
  • Cloud Infrastructure Design. This section provides an introduction to the cloud infrastructure design process.
  • Designing the Cloud Storage Infrastructure. This section provides information related to design considerations for building the cloud storage infrastructure using Windows Server 2012 platform features and capabilities.
  • Designing the Cloud Network Infrastructure. This section provides information related to design considerations for building the cloud network infrastructure by using Windows Server 2012 platform features and capabilities.
  • Designing the Cloud Compute (Virtualization) Infrastructure. This section provides information related to design considerations for building the cloud compute (virtualization) infrastructure using Windows Server 2012 platform features and capabilities.
  • Overview of Suggested Cloud Infrastructure Deployment Scenarios. This section provides information on three suggested cloud infrastructure deployment scenarios and the design decisions that drive selecting one over the other.

TCP Loopback Fast Path in Windows Server 2012 and Windows 8

leave a comment »

“The default behavior of the TCP loopback interface is to move local TCP traffic through most of the network stack, including AFD (which is essentially the kernel mode representation of a user mode TCP socket),  as well as the layers corresponding to TCP and IP protocol layers.

Windows Server 2012 and Windows 8 introduce a new optional fast path…

 

TCP Loopback fast path is just one of the Low Latency Workload support features in Windows Server 2012.

Microsoft Cloud OS and Private Clouds

leave a comment »

Ignoring the poor form of quoting oneself; in a post last year I commented on “amount of IT infrastructure capability it delivers as standard” in Windows Server 2012 and “Microsoft’s learning from the demands of running infrastructure at large scale with virtualization as an integrated part of that”. Microsoft’s recent announcement of System Center 2012 SP1  seems to reinforce this view.

The Register’s view on How to build a perfect private cloud with Windows Server 2012 shows how this might all be put together on-premise.

That article also raises a key point about application availability and whether that is delivered by the application or the infrastructure. The move to application replication that we saw with, for example, database availability groups in Exchange 2010 and the use of local storage in that application, has begged questions about when is a SAN functionality required (thinking hardware-based storage replication) and raises the possibility of replication to public cloud. Where to place the responsibility for application availability is tricky as infrastructure architects may be reliant on platform or application architects to be aware of what availability models are in the application; that information could surface through technology roadmapping and vendor management. The separation of the application (software), platform and infrastructure layers in private cloud architectures can be seen in both the Microsoft model:
