Cloudcenters are Datacenters in the Sky

Thursday, January 8th, 2009 by

Amazon’s Web Services (AWS) is not the only way to build scalable Cloud Infrastructures.  There are two emerging methodologies for constructing Infrastructure-as-a-Service (IaaS) AKA “Cloud Infrastructure Services”.  The first is what we call “cloudcenters”, which are essentially datacenters in the sky.  The second is what we call an “Infrastructure Web Service”.  GoGrid was one of the pioneers for cloudcenters, while AWS largely created the second model.

Infrastructure Cloud Models

Understanding these two approaches is important because it directly affects your selection of a Cloud Infrastructure provider.  These two models highlight a difference in core infrastructure and in target markets. Cloudcenters provide a direct equivalent to traditional datacenters and hence are usually more desirable for IT staff, systems operators, and other datacenter savvy folks.  Infrastructure Web Services on the other hand are more analogous to Service-Oriented-Architectures (SOA), require significant programming skills, and are much more comfortable for software developers.

Infrastructure Web Services

I’m going to assume for this article that you are somewhat familiar with Amazon Web Services (AWS), but I’ll briefly re-cap.  AWS provides a number of different ‘Web Services’ that can be consumed individually or put together to support different kinds of applications, usually a batch processing or web application of some kind.  These services include: (more…) «Cloudcenters are Datacenters in the Sky»
