The biggest strength is its fine-grained permission system. You can define policies that allow or deny very specific actions (down to a single API call on a single resource). That level of control is hard to match and becomes essential in production environments. Another standout is centralized security management. Instead of scattering credentials everywhere, IAM lets you manage users, roles, and permissions in one place. This becomes especially powerful when combined with roles—services and users can temporarily assume permissions instead of relying on long-term credentials. I also like its tight integration across AWS services. IAM is not an add-on; it’s deeply built into everything in AWS. Whether you're using EC2, S3, or Lambda, IAM policies consistently control access, which keeps your security model uniform.

What I like most about AWS Cloud9 is that I can open my project from any browser and start coding right away without setting up my local environment. I also like the built-in terminal and how easily it connects with AWS services. It has made testing small changes and working on different machines much more convenient.

What I like most about AWS IAM is how securely it lets me manage users, roles, and permissions through fine grained access control. It integrates smoothly with other AWS services, supports multi factor authentication (MFA), and aligns well with the principle of least privilege. Overall, it helps me maintain strong security without getting in the way of productivity.
