“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.”

There’s a growing amount of material available on Windows Azure Infrastructure as a Service (think virtual machines in the cloud):
but sometimes a concise demo is really helpful. Episode 53 of the (always excellent) EdgeShow at Channel9 has nice demo of Windows Azure IaaS that should whet the appetite of any IT professional be it an infrastructure architect involved in planning for private cloud or a developer thinking about the overhead of running your own test/dev or sandpit environment. The demo starts here; watch it and then read on…
…if building say, an on premise test/dev environment in a virtualisation infrastructure, then looking at the costs of running on Windows Azure and weighing those against the costs and complexity of building your own must be the first step. Information on Windows Azure trials and previews and pricing is here.
If you watch the demo you will (briefly) see the new VMdepot community that allows you to select from pre-built images on a variety of Linux distributions with various platforms e.g. LAMP stack, included.
For a broader overview on there’s a recent talk by John Craddock at the Nordic Infrastructure Conference 2013 on Windows Azure Insights for the Enterprise IT Pro; John explains, in passing, how you can leverage an MSDN subscription to trial the technology.
For a technical deep-dive on Windows Azure IaaS and virtual networks see Mark Russinovich BUILD presentation; you can also watch Mark’s presentation broken down into smaller modules with related learning materials on the associated Microsoft Virtual Academy course.
For a deep-dive on how to manage Windows Azure IaaS with powershell see Michael Washam BUILD presentation. Channel 9 also hosts a version of Michael’s presentation in bite-size chunks at Windows Azure Virtual Machines & Networking

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.
If you have ever studied ITILv3 you will have seen the Service Pipeline.
Here’s a very nice post that argues that “The service catalog has a central place in data center and cloud transformation“; Service Catalog is part of Domain 5 of Cisco’s Domain Ten framework for data center and cloud transformation. It also contains an interesting post on the history of the Service Catalog.
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:
and the Cisco Domain Ten blueprint; for more on the latter see Introducing Cisco Domain Ten(SM) – Cisco Services’ Blueprint for Simplifying Data Center and Cloud Transformation.
