VMware vs Citrix: Three points. One agree, two disagree

VMware vs Citrix

When attending a Citrix vs VMware session at Summit, there are two things I need to disagree with.

First, the VMware EUC sales strategy. Although Citrix meant this as a way to compete with VMware, the “Bottom-up” and “Top-down” approaches are spot-on—and I would contend, very effective. Built on vSphere success. Attaching Horizon, etc., and sweetening the ELA/licensing are all good ways to get in, and good reasons to go VMware. The “Box-in” approach, however, uses arguments from old Citrix technology, which both VMware and Citrix have outgrown; if the VMware reps are still using this argument, then I agree with Citrix. Bottom line: VMware’s sales strategy is effective.

Second is around provisioning. When Citrix talks about its own products, it compares PVS (Provisioning Services) and MCS (Machine Creation Services) and calls them relatively equivalent in performance and resource consumption. Then, there is a feature comparison with PVS vs VMware linked clones; but the comparison should really be made with MCS, where product functions are more equivalent. True, PVS does give you the ability manage images with auto-versioning, and rolling forward/backward with just a reboot, but MCS and VMware still push and image, which costs time. The advantage, however, to MCS and VMware’s Provisioning with Linked-Clones and View Storage Accelerator approaches is that they require no extra infrastructure; the feature set is built-in, where PVS requires its own infrastructure, including redundant servers, load balancers (depending on how it’s implemented), DHCP scope(s) (again, depending on how it’s implemented), etc. Perhaps Citrix will rectify the feature difference between PVS and MCS in the future—they’ve been alluding to it for a number of years now. But bottom line: The feature set between MCS and VMware’s Provisioning with Linked-Clones with View Storage Accelerator mechanisms are roughly equivalent these days. Perhaps in a future post, we’ll get the lab together and run the numbers.
