Elastic Compute Cloud (EC2) is AWS’s Infrastructure as a Service product. It provides a huge range of virtual machines suitable for general purpose and specialized on-demand compute tasks. In this hands-on lab, you will gain experience creating and interacting with an EC2 instance. The lab covers EC2 requirements, the choices available with creating EC2 instances, and the provisioning process itself. By the end of the lab, you will have gained the experience needed to be confident using EC2 in smaller deployments, such as blogs or lower-volume websites.
