IAM: Identity and Access Management in Cloud Computing
IAM controls who has access to AWS resources and what they can do. Core concepts: Users (people), Groups (collection of users), Roles (assumable identity for services), Policies (permissions in JSON).
Best practices: Enable MFA on root account, create individual IAM users (never share credentials), use groups for permissions, attach minimal policies (principle of least privilege). Never commit AWS credentials in code.
Policies are JSON documents defining allowed/denied actions on resources. Example: Allow S3 read-only on bucket "my-bucket". Roles are assumed by EC2, Lambda, humans. Service roles let services call other services (EC2 → S3).
