Amazon Web Services, the biggest public cloud service provider, is pushing back hard on private cloud providers. At its first user conference, AWS re: Invent, claims that private cloud users are not achieving all the benefits of cloud computing.
“Andy Jassy, senior vice-president at Amazon Web Services (AWS), told the AWS re: Invent conference that the full benefits of cloud computing are achievable only on a truly cloud-based service.” I assume he meant public clouds.
While private clouds are not as cost effective as public clouds, generally speaking, there are reasons to leverage private clouds. Of course, this depends upon the circumstances and the needs of the business.
I’m not sure that the AWS’s stance on “outside the firewall good, inside the firewall bad,” will serve them well in the long run. The destination is a mixture of private, public, and hybrid cloud computing solutions, all leveraged for different business requirements. If AWS wants to play in that world, they need to become a bit more sophisticated in how they deal with other technology solutions. There are never any absolutes in this business.
