On May 28th 2008, VMware announced that they were buying Applications Performance Management Vendor B-hive. The fact that VMware made this acquisition over a year ago, and is only now getting ready to ship the resulting product (AppSpeed) in concert with the vSphere rollout is in and of itself significant. The key message for vSphere is that it has the performance and scalability to virtualize “every” application, including business critical high transaction rate applications. The issue for enterprises with these applications is that the teams responsible for these applications are highly reluctant to insert another variable into their performance without a mechanism to assure the performance of these applications within the virtual environment. Assuring the performance of these types of applications in a virtual environment is a unique, demanding and largely unsolved problem. This problem must be solved in order for the growth of virtualization to extend beyond “low hanging fruit” and to include these business critical applications.
