Long-deferred vendor visions of agile data centers are finally coming true now that VMware virtualization with VMotion live migration has severed the ties that kept services fixed to x86 hardware. Unfortunately, some vendors are trying to stage a revival with an inferior substitute for live migration. Most notably, Microsoft is claiming that their "Quick Migration" feature is comparable to VMware VMotion and adequate for enterprise data centers, even though Quick Migration is not true live migration. We've even heard Microsoft tell audiences that our customers don't trust VMotion enough for production use. Don't fall for it -- VMotion is ready, proven and in heavy use today by VMware customers who are bringing true flexibility and agility to their IT operations.
