With the announcement of vSphere 5.0, VMware has kept its word on only having VMware ESXi for the physical host operating system. This is the first release of vSphere with just VMware ESXi as an option. I must admit that I was not a big fan of the concept when it was introduced as an option in the 3.x days. I had a very slick automated process in place that was one of my pride and joys at the moment and VMware ESXi was just lagging behind in functionality compared to what I was able to do with VMware ESX. My attitude started to change with the release of VMware ESX 4.1 as presented in an earlier post and now that vSphere 5.0 is announced I must admit that I think VMware has gone about this process of a cutover to ESXi quite well and the functionality that is presented in this release is quite impressive.
Just in time for the adoption of vSphere 5 by enterprises seeking to virtualize business critical and performance critical applications, AppFirst, BlueStripe, and ExtraHop have pioneered a new category of APM solutions. This new category is focused upon allowing IT to take responsibility for applications response time for every application running in production. This is an essential step on the road toward virtualizing the 60% of the applications that remain on physical hardware.
ExtraHop has now made an important contribution to the question of how to measure applications performance across physical and virtual environments. Properly deployed ExtraHop can play a critical role in helping enterprises virtualize the 60% of the remaining applications that are “hard”, “performance critical”, and “business critical”. As vSphere 5.0 is right around the corner, the timing could not be better.
