Introduction to AWS IAM

AWS IAM, short for Identity and Access Management, lets you control who can access your AWS resources and what actions they can perform. This is crucial for keeping your account secure and organized.

Why is it important?

With IAM, you can create separate user accounts for each team member or workload, granting only the permissions needed for their roles.

Instead of using your powerful root account, you assign day-to-day work to IAM users, reducing risk.

IAM allows the creation of groups for efficient permission management and supports temporary permissions via roles for services like EC2 and Lambda.

Key Concepts

• Users: Individual accounts for people or applications.
• Groups: Sets of users for bulk permission updates.
• Roles: Temporary permissions for AWS services or external users.
• Policies: Rules that define which actions are allowed or denied, keeping access tightly controlle

IAM is AWS’s shield for your resources—essential for security, organization, and smart cloud usage.
