I wanted to bring your attention this week to a brand new paper called "Deploying Oracle RAC using Oracle VM Templates—An Economic Impact Assessment." In the paper, Evaluator Group took a look at Oracle VM Templates with Oracle RAC versus user-created VMware templates. From the paper:
"Evaluator Group studied the creation and use of virtualized server templates as an administrative process for server deployments in an Oracle RAC environment—a process that can be surprisingly complex if done manually within any database environment.
This study was done in two ways:
• Evaluator Group conducted an independent lab comparison of template creation methods in an Oracle database application environment. We first built templates 'from scratch' and deployed virtualized servers for Oracle RAC under VMware while tracking the time consumed for each step in the process. We then repeated the same process of deploying virtualized Oracle RAC servers, but in this second iteration we used Oracle Virtual Machine (Oracle VM) and the templates that are included with Oracle VM to create clones of virtual machines. Again, we tracked the time consumed for each step in this process.
• We also interviewed an Oracle systems administrator as a basis for additional comparison of building templates in a production environment. For this customer, templates were a “game changer” because of an ability to deploy database and business intelligence services up to twenty times faster for their customers.
Evaluator Group conducted this study of both methods to compare the two on the basis of management complexity, risk resulting from administrative error, and overall time consumed."
One of the really cool things in this paper is some real world data from a customer using Oracle VM and Oracle Linux and the total cost of ownership reductions they were able to achieve. Have a read of the full paper.
Have a great week!
