Compute
Vertical Scaling
From $0.02/hr Elastic Compute Cloud (EC2) Basic unit of compute capacity
Range of CPU, memory & local disk options
18 Instance types available, from micro to cluster compute
Feature Details
Flexible Run Windows or Linux distributions
Scalable Wide range of instance types from micro to cluster compute
Machine Images Configurations can be saved as machine images (AMIs) from which new instances can be created
Full control Full root or administrator rights
Secure Full firewall control via Security Groups
Monitoring Publishes metrics to Cloud Watch
Inexpensive On-demand, Reserved and Spot instance types
VM Import/Export Import and export VM images to transfer configurations in and out of EC2
