- EC2=Elastic Compute Cloud (Computing/processing in a cloud)
- S3 = Storage in a cloud
- SQS=Simple Queue Service (Messaging between different parts of applications)
- SDB=Simple Database (Database in a cloud)
- Flexible Payment Service (Money processing. They don’t call it FPS for some reason🙂 )
Above those services they offer Dev Pay which allows developers to put their own business model over the infrastructure.
Very interesting business model for Amazon.
