Today in Cloud

The cloud computing stack has been around for a while, with the core three layers of Infrastructure, Platform, and Software/Applications playing a valuable role in helping people explore the different ways in which they might exploit cloud. Amazon CTO Werner Vogels used his Structure presentation last week to argue that the stack is outdated. Now, it’s true that most use cases require pieces from up and down the stack, and that traditional Infrastructure providers like Amazon haven’t fit neatly in an Infrastructure-only box for some time. Nevertheless, the broad functional and conceptual differences that separate raw compute and storage at the bottom from enabling development platforms in the middle and actual applications on the top still have merit. The spectrum still makes sense; just don’t try to peg real world implementations to a single point along it.
