Virtual servers, instance families, launching an instance, and EC2 pricing options.

Amazon EC2

Slide 1 / 5

Amazon Elastic Compute Cloud (EC2) provides virtual servers, called instances, in minutes. You choose the operating system, the size, and the software, and pay only while the instance runs.

EC2 uses multitenancy: many customers' instances share physical hosts, isolated from one another by a hypervisor that AWS manages.

You can scale capacity up or down at any time β€” no hardware to buy or retire.
