Database workload virtualization and you

Derek Kuhr Derek Kuhr Profile: Derek Kuhr

When I was first asked to investigate how increased use of virtualization technology will affect DBA careers, I was a little confused. To be honest, I didn’t immediately see the connection. I figured, ‘well, if the database is on a virtualized server, they’ll just manage it like they will any other database and their jobs will pretty much be the same.’

Boy was I wrong.

After looking into the issue more, I realized that database virtualization will mean a lot of change for the DBA. And at the very least, they’re going to want to familiarize themselves with some tips for making the process of database workload virtualization a simpler one.

You can read all about that stuff in one of my latest stories, “Virtualization means changing roles for DBAs.” But here are some highlights:

  • New technology is coming from Intel and AMD that will one day make database workload virtualization an easier process than ever before.
  • DBAs virtualizing workloads today need to be intimately familiar the behavior of their database workloads over time, or else the performance cost associated with virtualization could be too high.
  • DBAs working in Unix environments should become familiar with virtualization management and workload management software to manage database partitions and to help them anticipate spikes in demand that happen at certain times of the year.
  • More and more organizations are talking about virtualizing data itself as a way of getting up-to-date information quickly to increasingly service-enabled applications.

Some DBAs, such as the one interviewed for the article, say they are having success with database virtualization today. What’s your experience in this area? Are the performance costs of virtualizing databases too high at your organization? Let’s get a discussion going.
