This article has been updated with a 2013 revision.
Earlier this year Daniel Feller wrote a great blog article on how to choose between PVS or MCS . This article can be found here.
With the release of the XenServer Intellicache feature and Provisioning Services 6.0 the question is “Is the decision tree still valid”?
This is what I will try to answer in this article.
One of the sessions on Citrix Synergy was all about Citrix Provisioning Services. I watched it online and was wowed because the session was all about the next version of Citrix Provisioning Services version 6.0.
In an earlier article I wrote that I personally don’t get why Citrix created a new Provisioning feature called Machine Creation Services. With the release of XenServer 5.6 SP2 and XenDesktop 5 SP1 things changed!…… a bit.
When Citrix launched XenDesktop 5 I was mostly wowed by all the new features and great consoles. Citrix did a great job in creating a true VDI platform instead of a XenApp spin off which wasn’t good enough for large VDI environments.
Among with XenDesktop 5 Citrix released a new feature called “Machine Creation Services” (MCS). MCS is a sort of lightweight alternative for Provisioning Services (PVS). To be completely honest I totally ignored the feature at first because of the negative IOPS and scalability impact but the last couple of weeks customers are asking about it.
