Introduction to AWS Identity and Access Management

AWS Account

To start using AWS resources and services, you must first create an AWS account. AWS operates on a pay-as-you-go model—there are no upfront costs, and you only pay for what you use at the end of each billing cycle. Many organizations leverage multiple accounts for isolation, billing, and security, then consolidate costs using AWS Organizations.

Why Create an AWS Account?

  • Instant access to cloud services (compute, storage, databases, and more)
  • Flexible, pay-as-you-go pricing with no long-term commitments
  • Strong isolation between development, testing, and production environments
  • Consolidated billing across multiple accounts for streamlined cost management
  • Secure cross-account resource sharing and access control

Key Benefits of AWS Accounts

The image outlines five benefits of creating an AWS account, including access to cloud resources, a pay-as-you-go model, account communication, consolidated billing, and creating accounts for different departments.

Demo: Creating an AWS Account

Follow these steps to register and activate your AWS account:

  1. Open your web browser and navigate to https://aws.amazon.com.
  2. Click Create an AWS Account.
  3. Enter a valid email address and choose a strong password.
  4. Specify an account name (alias) to identify your AWS account.
  5. Complete the registration form with contact details, payment information, and identity verification.
  6. After receiving confirmation, sign in as the root user using your registered email.

Warning

Avoid using the root user for daily operations. Create IAM users with the least privilege necessary and manage permissions through AWS IAM.

The image is a guide for creating an AWS account, featuring a simple illustration of a person with a "Demo" sign and instructions to visit the AWS website and enter an email address to create a password.

Next Steps

  • Create IAM groups, users, and roles for granular access control
  • Enable multi-factor authentication (MFA) on the root account and IAM users
  • Set up AWS Organizations for consolidated billing and policy management
  • Explore AWS Cost Explorer and Budgets to monitor spending
