IAM Roles and Permissions

Welcome! In serverless applications, security is paramount. AWS Identity and Access Management (IAM) is your key tool for managing who (or what) can do what in your AWS account.

For Lambda functions, IAM roles define the permissions your function needs to interact with other AWS services, like reading from a database or writing logs.

AWS IAM stands for Identity and Access Management. It's a service that helps you securely control access to AWS resources.

• You can manage users, groups, and roles.
• You define permissions using policies.
• It ensures only authorized entities can perform actions.

Think of it as the security guard and rulebook for your AWS cloud.
