AWS Identity and Access Management
AWS Identity and Access Management (IAM) is a web service that helps you securely control access to AWS resources. It enables you to manage users, groups, roles, and permissions to define who can access what within your AWS environment. IAM is a core component of AWS security, providing fine-grained access control and integration with other AWS services.
Developers should learn IAM when building or managing applications on AWS to implement security best practices, such as the principle of least privilege, and to automate access management through roles and policies. It is essential for securing cloud infrastructure, managing multi-account setups, and enabling secure access for applications, services, and users, particularly in DevOps and enterprise environments.
