AWS IAM and AWS Organisation, Which Service I should Prefer Over Another

AWS IAM (Identity and Access Management) is a service provided by Amazon Web Services (AWS) that enables you to manage user identities and their access to AWS resources. IAM allows you to create and manage users, groups, and roles, and assign specific permissions to them. With IAM, you can control who can access your AWS resources and what actions they can perform. IAM helps you maintain security and ensure that only authorized individuals or services can interact with your AWS environment.

AWS Organizations is a service that helps you centrally manage and govern multiple AWS accounts. It provides a way to organize your accounts into a hierarchy, called an organization, and enables you to apply policies across those accounts. AWS Organizations simplifies the management of security, compliance, and cost control across your AWS infrastructure. It allows you to consolidate billing and provides a framework for managing and sharing resources across multiple accounts.

When it comes to choosing between IAM and AWS Organizations, it’s important to understand that they serve different purposes:

1. IAM focuses on managing user access and permissions within a single AWS account. It is essential for controlling access to resources and ensuring security within that account.

2. AWS Organizations, on the other hand, is designed to manage multiple AWS accounts and apply policies across them. It helps you establish a multi-account structure for your organization and provides a centralized way to manage and govern those accounts.

So, if you have a single AWS account and want to manage user access and permissions within that account, you would primarily use IAM. However, if you have multiple AWS accounts and need to manage them together, enforce policies across accounts, and consolidate billing, you would benefit from using AWS Organizations.

In many cases, you will use both IAM and AWS Organizations together to effectively manage access and permissions within your AWS accounts and across your organization’s infrastructure.

I am still not clear, please read more . . .

AWS IAM is like a special guard that helps protect a big treasure chest full of valuable things. This guard is responsible for making sure that only the right people can access the treasure chest and that they can only do certain things with the treasures. The guard creates special keys for each person, and these keys allow them to unlock the chest and use the treasures inside. The guard decides who gets what keys and what they can do with them. This way, only the people who are supposed to have access can get to the treasures, and they can only do what they’re allowed to do.

Now, imagine you have a lot of treasure chests, each with different valuable things inside. AWS Organizations helps you manage all these treasure chests. It’s like having a boss who can oversee all the guards protecting the treasure chests. The boss makes sure that the guards are doing their job properly and follows the rules. With AWS Organizations, the boss can also decide how the treasure chests are organized and who can access them. It helps keep everything organized and ensures that everyone is following the rules.

So, to summarize, AWS IAM is like a guard who protects a treasure chest and decides who can access it and what they can do with it. AWS Organizations is like a boss who oversees all the guards and makes sure everything is organized and everyone follows the rules.

Remember, this is a simplified explanation, but I hope it helps you understand IAM and AWS Organizations!
