November 12, 2008There is a lot of promise in the use of virtualization, but it's rare to hear vendors mention the complexities associated with its use.
They understand it, work hard to hide it, and have ambitious plans to manage it. Media such as Computerworld, SearchDataCenter.com and eWeek have devoted time to discussing the complexities associated with managing virtual environments. We've all heard the benefits of virtualization. For example, you can deploy multiple operating system technologies on a single hardware platform. Â
However, we all know and appreciate that when any system becomes congested it will slow and potentially fail. To unclog bottlenecks, we need to know where they are in the system.
As we know, virtualization's promise is to make things easier by hiding complexities. We also know that virtualization is more complex and harder to understand when it fails. Visibility or transparency into the system is paramount to remediating problems with the system.
What do you need to effectively manage your virtual environment? What's missing from the current management tools for server virtualization, as an example?
With whatever virtualization solutions you are looking at, encourage your vendor to put in the instrumentation and telemetry so that when the system is suffering â€“ and it will eventually â€“ you can remediate quickly.
