How To Create Iam Roles For Aws Lambda Function?
AWS Training and Cerifications
Before elaborating we must start with the basics. First of all, let us understand what is IAM Roles? AWS Identity and Access Management (IAM) is a web service for securely controlling access to AWS resources. This service handles authentication and authorization for calls made to the AWS resources. IAM allows access to computing, storage, database and application services. IAM deals with 3 terms such as users, groups, and permissions. Components of IAM are:
User: An individual who has a set of permissions is an IAM User.
Groups: A Collection of IAM users is called as IAM Groups.
Roles: Set of permissions for making AWS service requests.
Policies: IAM Policies Specify those permissions that you want to acquire.
Lambda is a “function as a service” service and in a single word it can be described as “serverless computing”. In comparison to previously deployed web applications, in serverless architecture, the developer does not has to maintain the servers or the infrastructure. They only have to pay a subscription to the third-party vendor whereas the vendor is responsible to handle the operation of the backend logic of a server along with scalability, reliability, and security.
now, how we will create IAM roles or Execution role to AWS Lambda Function?
So for this follow the steps below-
Log into the AWS console.
Navigate to services and then search for IAM in the search box. IT will redirect you to the IAM Management Console.
From there, click on Roles, then click on Create Roles.
From the Four entities visible on the screen, select AWS Service. In this select Lambda then click on NEXT.
All the listed policy names are visible, from this search and attach S3 full access.
Assign the Role Name, change the description if u want then click on Create Role.
The Role is created now. Check it into the Lambda Console by navigating to the execution role.
This is how we create IAM roles for AWS Lambda.
