What is a lambda function?
When managing EC2 instances, lambda functions concentrate on specifying why they are there in order to launch and stop instances quickly. For implementation, use Python with Boto3, making sure to follow clean code guidelines and handle errors appropriately. To ensure a smooth integration of the function into your AWS environment, configure IAM roles with granular permissions.
Here are a few benefits of using the lambda function:
- The overhead of managing servers is eliminated with serverless architecture.
- Under changing workloads, automatic scaling guarantees consistent performance.
- A pay-per-use pricing strategy that only charges for compute time optimizes expenses.
IAM Role
The administration of EC2 instances by the AWS Lambda function places emphasis on the establishment of an IAM role that grants rights such as AmazonEC2FullAccess in order to guarantee correct execution. Furthermore, emphasize how this role may be attached to the Lambda function for easy integration and efficient management of EC2 resources. For more details on how to create the AWS IAM role, refer to this link.
Lambda Permission
Before defining the Lambda function’s permissions, make sure to include IAM roles that grant the required access, like AmazonEC2FullAccess, to allow smooth EC2 instance management. To improve security posture and restrict access to only the required assets and actions, make sure that the least privilege principles are followed. Finally, to facilitate seamless integration and execution within the AWS environment, link the IAM role to the Lambda function.
How To Create Cron Job In AWS Lambda?
A Cron job works like scheduling a task in any system. It is mainly used for backups, system maintenance, etc. Cron’s job works on both local systems as well as cloud services. To run the crown job in AWS, we have to use AWS Lambda. In AWS Lambda, we set up the functions and schedule a time to run them.
