What is Amazon EC2?

Amazon Elastic Compute Cloud (EC2) is a web service that provides secure, resizable compute capacity in the cloud. It allows you to launch virtual servers (instances) on demand, choosing from various instance types optimized for different workloads. EC2 offers complete control over computing resources with the ability to scale capacity up or down based on demand. You can choose from multiple operating systems, configure security and networking, and manage storage. EC2 integrates with other AWS services and provides flexible pricing options including On-Demand, Reserved Instances, and Spot Instances.
