Vol. 17, #42 - October 15, 2012 - Issue #901
This week's issue of WServerNews is all about Infrastructure as a Service (IaaS), which is another of the three basic models for delivering cloud computing services to customers. But the question is, how much should we CARE ABOUT THE INFRASTRUCTURE BEHIND CLOUD SERVICES?
Before we start, two things. First, in case you missed them (or simply want to re-read them) here are links to the previous newsletters in our Cloudy Thinking series:
And second, why the HecK do they have to abbreviate them as SaaS, IaaS and PaaS? After all, SAAS, IAAS and PAAS are a LOT easier to TYPE...
You might remember that there are three basic cloud service models:
Previously we looked at SaaS, which is where a service provider hosts line-of-business applications and you (i.e. your business) pay them a usage-based subscription fee to allow your users to use these applications. A good example of a SaaS offering is Office 365, which you can find out more about here:
Now let's talk about IaaS, which is where the service provider hosts a shared pool infrastructure resources such as storage, networking and virtualization hosts. Customers pay for these resources on a usage-based subscription basis so they can have virtual servers running in the cloud. The customer is responsible for configuring and managing their virtual servers.
For example, let's say you have a new business and you need a database server. Instead of purchasing hardware and software and rolling your own, you could rent a virtual server from an IaaS provider on a subscription basis. Employees (or customers) can access this cloud-based database server as easily as they could access an in-house server.
Now let's say your business is rapidly growing, and you estimate that next week you'll need three more database servers to handle the load. With IaaS it's simple to spin up more virtual machines for your organization's needs. In fact, the hoster probably provides a self-service portal for you to do this on your own instead of having to contact them in person.
Then the economy goes into a slump. If you bought physical servers, some of them will now be gathering dust in your server room. But if you leased virtual servers from an IaaS provider, you can simply spin down the servers you no longer need and your subscription fee should change to reflect this.
IaaS - The Good
IaaS can be a good solution for businesses that want to manage and control infrastructure (operating systems, applications, middleware, frameworks, storage, etc) but don't want to host it on-premises.
IaaS lets customers customize their server and application environments the way they want them.
IaaS streamlines the server provisioning process and also makes it easy to de-provision servers and storage resources that are no longer needed.
IaaS reduces the upfront cost associated with purchasing server hardware, and helps make budgeting IT costs more predictable.
IaaS - The Bad
Make sure your service level agreement (SLA) with the provider guarantees a high level of availability for the virtual server you host in their cloud.
If you experience problems with line-of-business applications running on your virtual servers, it's your own responsibility to fix these as your SLA doesn't guarantee application uptime, only virtual server availability.
IaaS - The Ugly
I don't think there's really anything ugly about IaaS, unless of course you consider installing, configuring, managing, monitoring and troubleshooting server operating systems and server applications an ugly profession...
Some IaaS hosting providers
As far as I'm aware, Microsoft doesn't actually run an IaaS cloud you can use for hosting your organization's virtual servers. What they do offer however are the tools that hosters can use for building such IaaS clouds. These tools of course are Windows Server 2012 and the soon-to-be-released Service Pack 1 for System Center 2012. Service providers who want to build IaaS clouds can do so using their Microsoft Solution for Service Provider offering described here:
But there are many other players in the IaaS hosting space, some of them established. Here are three I can think of from off the top of my head:
Rackspace Cloud Servers

If you want to run a Windows 8-based or Windows Server 2012-based virtual machine on a Hyper-V host running Windows Server 2008 or in Windows Server 2008 R2, you may have already discovered that you needed to download and install the KB 2526776 hotfix on these hosts to make this work.
Well, that KB article has been pulled from the Microsoft Support site and has been replaced with a new one KB 2744129:
The new KB article has an updated version of the hotfix that fixes some issues with the previous version.
