Yesterday, Microsoft announced the general availability of its offering of Infrastructure as a Service (IaaS). They join an already-crowded market of IaaS providers, but this offering gives all companies the ability to offload workloads that have traditionally run in a company data center to the cloud. Welcome, Microsoft — the water is fine.

This announcement also represents a major chunk of Microsoft’s family of Azure offerings…and in my opinion, a stepping stone many companies simply must take in moving out of the traditional data center and into the cloud.  The following diagram shows the stepping stones out of the traditional data center:

In a previous blog post I discussed Windows Azure PaaS / IaaS hybrid scenarios. Together with my colleague Jack O’Connell (Infrastructure Specialist extraordinaire), we set up each of the four scenarios outlined in the previous post including:

  • Using Windows Azure Virtual Network to provision a VPN to connect our on-premised infrastructure with a Windows Azure datacenter.
  • Set up front-end and back-end subnets.
  • Provision a set of Azure IaaS Virtual Machines and Azure Web Roles.
  • Install System Center Monitoring Pack for Windows Azure Applications on Azure-based machines.
  • Install System Center Operations on-premises in order to manage Azure-based resources.

Watch the following video for a quick walkthrough of the scenarios in action:

If you have found yourself thinking…

“We want the cloud to be a seamless extension of our data center, not a walled garden. We want to use our existing IT setup and tools (AD, SCOM etc.) to manage the on-premises and cloud-based applications.”

“We want seamlessly move virtual machines from on-premises to the cloud and back.”

“We want to start out by moving existing applications to the cloud without the need to change the applications in any way.”

…then our upcoming Introduction to Windows Azure IaaS session is for you.

In the past, I have written about the benefits of Platform as a Service (PaaS) style of applications. While I continue to believe that PaaS offers the best ROI for hosting custom applications in the cloud, there are a number of scenarios where inserting elements of Infrastructure as a Service (IaaS) to a PaaS solution can help alleviate some of the limitations that have prevented the adoption of PaaS. In this blog post we will look at a few compelling scenarios that are enabled by combining PaaS with the recently announced IaaS features within a Windows Azure Cloud Service. Read More…
