<a name="ec2-examples"></a>

Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides virtual server hosting in the cloud. It’s designed to make web-scale cloud computing easier for developers by providing resizeable compute capacity.

All the example code for the Amazon SDK for PHP is available [here on GitHub](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/php/example_code).
