Open your AWS account: Glossary

Key Points

Create Your AWS Account

  • Your new AWS account is automatically entitled to the one-year AWS Free Tier.

  • The Free Tier has some limits that you must observe in order not to incur unwanted costs.

  • The link to login to your account in the AWS Management Console is https://aws.amazon.com/console
Configure Your AWS Account

  • The Root account should only be used for high-level admin tasks.

  • IAM accounts should be created and configured for daily use.

  • Your IAM user account has the permissions of the (account) AdministratorAccess policy, and is hence sufficient for most practical purposes.
