IAM

Identity and Access Management (IAM) provides the granular security framework required to control who can access specific cloud resources and what actions they can perform.

IAM is the gatekeeper of the modern tech stack. It manages digital identities through a combination of users, groups, and roles to enforce the principle of least privilege. By using JSON-based policies, administrators define precise permissions (such as allowing an EC2 instance to read from a specific S3 bucket while denying delete actions). This system integrates multi-factor authentication (MFA) and temporary security tokens to eliminate long-term credential risk. Whether you are scaling a startup on AWS or managing legacy enterprise migrations, IAM ensures that every API call is authenticated and authorized before execution.
