What Is The Difference Between Iam Roles And Profiles?
IAM roles and profiles are essential components in AWS (Amazon Web Services) that help manage access permissions and secure resources. Let’s clarify the difference between IAM roles and profiles.
An IAM role represents a set of permissions that can be assumed by AWS resources like EC2 instances. Think of it as a collection of permissions policies that define what actions can be performed on AWS services and resources. These roles can be assumed by various entities, such as EC2 instances, Lambda functions, or even users within your AWS account. When an entity assumes an IAM role, it temporarily inherits the permissions associated with that role.
On the other hand, an instance profile is essentially a container for an IAM role. Specifically, when you launch an EC2 instance and associate it with an instance profile, you are providing that instance with the necessary credentials to assume the IAM role defined in the profile. This allows the EC2 instance to access AWS services and resources according to the permissions granted by the IAM role, without requiring you to manually manage access keys or credentials.
In summary, IAM roles define permissions, and instance profiles provide the necessary credentials for EC2 instances to assume those roles. This approach enhances security and simplifies credential management, making it easier to control access to AWS resources.

What Is The Difference Between Iam Role And Root User?
Distinguishing Between AWS IAM Roles and the Root User
Understanding the contrast between AWS Identity and Access Management (IAM) roles and the root user is crucial for effectively managing access within your AWS environment. An AWS IAM user with administrative privileges possesses extensive capabilities, closely paralleling those of the root user. However, it is important to note that there are certain tasks reserved exclusively for the root account. One critical consideration is that if you decide to delete the root account, an action that some security experts may recommend for enhanced security, you should be aware that specific functionalities will become permanently inaccessible. This distinction underscores the importance of carefully assessing your security strategy and access control policies within AWS. (Published on July 18, 2022)

An IAM role is an identity within your AWS account that has specific permissions. It is similar to an IAM user, but is not associated with a specific person.An instance profile is a container that holds an IAM role. When you launch an EC2 instance with an associated profile, the instance can then use the permissions granted by the IAM role to access only those AWS services or resources the role permits—without having to manually manage credentials or access keys.AWS Root User versus IAM User
An AWS IAM user granted administrative privileges can do almost everything a root user can do, except for a few tasks that are restricted to the root account. If you delete the root account, which some security professionals may advocate, these changes will be permanently inaccessible.
