Amazon has introduced a way to pay for cloud infrastructure that undercuts Google – provided you're willing to shell out up front towards at least one year of use.
Amazon Web Services (AWS) has changed the way it charges for its Reserved Instance (RI) compute infrastructure on its Elastic Compute Cloud (EC2). EC2 customers pay for Reserved Instance infrastructure whether they use it or not, unlike EC2's On Demand Instances.
The charges for Reserved Instances are no longer split into light, medium and heavy usage but instead reflect how much a user is willing to pay up front.
Users can chose to pay no up-front costs, or some or all of the costs up front, and must commit to paying for one or three years of usage. A table produced by the cloud portfolio management company RightScale summarises the available payment options below.
