Amazon Web Services opened up its utility computing service, the Elastic Computer Cloud (EC2) beta, to all developers, adding large and extra large instance types to provide more flexibility to EC2 users.
"[The] 'elastic' nature of Amazon EC2 allows any developer to reach the scale of major Internet players like Amazon.com, but without the significant cost of building out and maintaining a massive back-end infrastructure," the company said in a statement. "Amazon EC2 changes the economics of computing by allowing developers to pay only for the capacity they actually use."
The EC2 service provides developers with rentable virtual computing environments. The company charges based on computing time and storage usage (S3). This model allows Web businesses to quickly scale up without having to cope with the issues of scaling up the technological infrastructure.
