Recent talks between Amazon and VMware could ignite a second wave of cloud adoption, this time focused on brownfield cloud migration. A recent report covered by CNBC raises the specter of a massive shift of workloads from premises to clouds, something of notable concern to at least a dozen premises-bound tech leaders and perhaps a couple dozen third party data center players managing traditional stacks.

This development represents a fundamental shift for Amazon and VMware, and each has their own distinct reasons for this once unlikely alliance. Amazon finally recognizes the value of the hybrid cloud model, which it has dismissed for years. This could be as much about Amazon growth as countering Azure’s massive inroads into cloud. See a few highlights from my blog Amazon, AWS and the Public Cloud Paradox from early 2013:

“As discussed previously, the total addressable market for VMware server virtualization and private cloud is about $50B dollars, per a VMware presentation made late in 2012.Amazon’s AWS revenues, representing an estimated 90% of the public cloud market, were under $3B.This suggests a wide gulf between the public cloud and private cloud market and an even larger $60B hybrid cloud market that is available to the victors.”

“That public cloud myopia on the part of Amazon, which was so prevalent at last year’s AWS reInvent Conference, is an albatross around the neck of what has otherwise been perhaps one of the most successful and revolutionary launches since… online bookselling.Amazon’s future success may depend more upon its ability to lead the cloud market versus being a former first mover.”

“Amazon clearly understands that public IaaS is too limiting, and has made a series of smart improvements to its cloud offerings that align them more closely to enterprise requirements.It is possible and reasonable to suggest that Amazon’s enhancements (along with Azure’s coming grand entrance) may have forced VMware’s hand into its own IaaS offering, much to the unease of some key VMware partners.Yet Amazon today is still stuck in the public cloud mindset.”
