Getting started with AWS

Amazon has a pay-as-you-go model and will charge the user only for the service used. Here, one can sign up with Amazon Web Services by going to www.amazon.aws.com where we can create an account and also fill the credit card details.

They also provide high availability using availability zone. Availability zone is nothing but a physically separated area within a region which means one data centre has multiple availability zone (physically separated).
