What is AWS?

AWS is a famous Cloud Provider handled by Amazon. It offers various cloud computing services that are accessible over the public Internet.

For creating VM or EC2 instances AWS used Citrix Hypervisor.

What is AWS IAM?

AWS Identity and Access Management (IAM) is a web service that helps you securely control access to AWS resources. With IAM, you can centrally manage permissions that control which AWS resources users can access. You use IAM to control who is authenticated (signed in) and authorized (has permissions) to use resources.

a) The IAM user limit is 5000 per AWS Account. At one time you can add 10 users.

b) You can create 300 groups per AWS Account.

c) You can create 1000 roles under one AWS account.

d) Default limits to managed policies attached to IAM Role and IAM user is 10.

e) One IAM user can be a member of 10 groups.

f) We can assign two access keys to one IAM user.

Features of AWS IAM:

a) You can share your AWS account with 5000 users without giving your credentials.

b) You can permit users as per the requirement.

c) You can give permission level like if you want to permit to access EC2 instances but that person can’t create a new instance or delete an instance, so you can remove that access.

d) AWS IAM provides Multi-Factor Authentication also, in that you can add two-factor authentication.

e) In AWS IAM Identity Federation feature is also available, In this case, believe on a third-party application to authenticate.

f) Identity Information for assurance, whatever people are trying to access you got that report. If you use AWS CloudTrail then you receive log records that include information about those who made requests for resources in your account

g) AWS provides IAM service free.
