The “big three” public cloud providers are turning their sights to legacy workloads. It will be interesting to see how customers adopt and deploy VMware on AWS, Azure Stack and, now, Google Nested Virtualization.
One knock on public clouds from Google, Amazon, and even Microsoft is that they are terrific for brand-new software built to take advantage of their resources, but not so great for existing, older business software developed and deployed before the cloud era kicked off 10 years ago.
The cloud players are working to address that issue. Many companies don’t necessarily want to rebuild applications that run just fine so they can move to someone else’s cloud data centers.
