Combining Virtualization Approaches

While server virtualization seems to get the bulk of virtualization mindshare, there are several other approaches that are worthy of consideration.  Examples including presentation, application, storage, and network virtualization.  In fact, you can effectively combine these different approaches to find the best performing and most cost-effective solutions to common IT problems. 

That’s the topic of my SearchServerVirtualization.com article, Combining virtualization approaches for a data center’s ‘secret sauce’.  From the introduction to the article:

Being an IT professional is similar to being a good cook. Even if you have great ingredients, success is realized only when you combine these ingredients in the ideal way. The same holds true for virtualization — many technologies can work well together. The art is in determining which applications and services will benefit from one another.

The good news is that virtualization doesn’t come in just one flavor — administrators have numerous options from which to choose. You can combine different virtualization approaches to address some of the more difficult data center management tasks.

As long as you can handle some cooking-related puns, I hope the information provides to be useful.

Best Practices to Prevent and Manage Virtual Machine Sprawl (White Paper)

Sun-manage_vm_sprawlOften, new technology tends to bring with it some new problems that need to be addressed.  Granted, the problems are “better” ones to have, but they’re important concerns nonetheless.  Server virtualization is no exception.

It’s somewhat ironic that one of the main problems that server virtualization is designed to address, server sprawl, is often replaced with a similar problem – VM sprawl.  It’s a topic that I’ve written a lot about in the past and on this blog.  I recently revisited the topic and expanded on it in a White Paper that I wrote for Sun.  Here’s the introduction from Best Practices to Prevent and Manage Virtual Machine Sprawl:

While server consolidation using virtualization can significantly decrease costs and improve efficiency, organizations often find that they need to deal with an associated issue: the rapid proliferation of VMs with inadequate management. This article will provide best practices for addressing the issue of "VM Sprawl", including the following:

  • Creating and enforcing deployment policies
  • Detecting and addressing unauthorized VMs
  • Managing security and compliance in virtual environments
  • Managing the entire VM lifecycle and Planning for VM retirement
  • Sidebar: Steps to gaining (or regaining) control of a virtual environment.

The White Paper is available for free, but registration on the Sun Web site is required.
