3 Ways of Accessing AWS Accounts, Services, and Resources

1. AWS Management Console UI
2. AWS CLI (Command Line Interface)
3. AWS SDK (Software Development Kit)

AWS Management Console (Colloquially: AWS Console UI)

• 🔧 Web UI → Access via web browser
• ❗ Must log in as an defined identity in the account: root user, IAM user, or IAM role
  • Access protected by password and potentially MFA
• 💡 Interacting with Console UI is usually called “ClickOps” since you do a lot of operations by clicking. In contrast, IaC (Infrastructure as Code) and DevOps (Development Operations) rely on scripts, code, and automation to perform operations with AWS services and resources

AWS CLI (Command Line Interface)

• 🔧 Execute commands in a shell/terminal to interact with AWS services via their public APIs
• Must first install AWS CLI in your system
  • Instructions (see DEMO on IAM Access Keys): https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html
• Open-source: https://github.com/aws/aws-cli
• ❗ Requires IAM Access Keys
