  • Elastic Compute Cloud (EC2), a service for provisioning computing resources on demand

  • Simple Storage Service (S3), online storage for opaque data

The original primary intent of AWS was to resolve scalability issues within Amazon itself, but even in its initial proposal in 2003 it was recognized that the new infrastructure could also be offered to customers.

The next prominent services to be added to the AWS suite included:

  • Elastic Block Store (EBS), persistent disk-like storage for EC2 instances, in 2008
