Virtualization: Quick Migration versus Vmotion
A few weeks ago here on System Center Forum, I descibed (at least in part) the role of Operations Manager 2007 in virtualization initiatives.
Recently, I ran across a good deep dive on how Quick Migration (Hyper-V) and Vmotion (VMware) actually work under the hood I think will be of interest to many of you.
While the technical bits in these articles are great, take the business case in part 2 with a grain of salt. While Vmotion definitely has the advantage over Quick Migration in terms of downtime, I think one could plausibly develop some alternate strategies for maintaining high availability at the application layer that could offset some or all of the disadvantages of Quick Migration shown in the scenario described.
As you may be aware, Virtual Machine Manager 2008 beta was announced at MMS. VMM 2008 provides management of not only Hyper-V and VS 2005 R2, but VMware ESX as well. With this release and the Operations Manager 2007 integration with VMM, it is clear MS plans to fight its next battles in the virtualization war on the front-end, providing effective management tools with broad heterogeneous management capabilities.
