First of all, you need to sign up to AWS. AWS gives a free tier that allows you to use some amount of AWS resources, free for 12 months. Go to https://aws.amazon.com/free/ to register your information and credit card. It may take 24 hours to verify and activate your account.

Once your AWS account is activated, we need to create one Identity and Access Management (IAM) user, which will control your AWS infrastructure via APIs. Then, install the AWS CLI on to your computer.
