Cloud computing is a new way of accessing computer resources on-demand over the internet. This will be a basic tutorial on Amazon Web Services (AWS), one provider of cloud computing. The tutorial will show how to use the Elastic Compute Cloud (EC2) to set up a virtual computer with the necessary hardware and software: CPUs, memory, storage, operating system, packages. The final goal is to demonstrate how to request the resources, connect to the computer using ssh, put some code and run it!
