If you don't already have an AWS account, then head over to https://aws.amazon.com/ and sign up for one. Before you can create resources in your account, you will need to add a credit card to your account to cover any charges.
When you first sign up for an AWS account, you will be eligible for a free usage tier on some services for the first 12 months. Unfortunately, this free tier doesn't provide quite enough resources to run Kubernetes, but in this chapter, we have optimized our choice of instances for their low cost, so you should be able to follow the examples without spending too much.
