You are a DevOps Engineer in your company. There is a requirement to send customized notifications whenever an EC2 Instance is scaled in or scaled out in an Auto Scaling Group. Which of the following steps can be implemented to fulfil this requirement? Each step forms part of the solution.

Answer options:

A.Create a Lambda function that sends customized notifications.
B.Create a CloudWatch event rule that triggers the Lambda function.
C.Create an SQS queue that writes the events to CloudWatch Logs.
D.Create a CloudWatch event rule that triggers the SQS queue.

Answer - A and B
The AWS documentation mentions the following
You can run an AWS Lambda function that logs an event whenever an Auto Scaling group launches or terminates an Amazon EC2 instance and whether the launch or terminate event was successful.
Options A and B are correct because the CloudWatch Event rule can trigger the Lambda function and the function can perform the required actions.
Options C and D and incorrect because the SQS queue cannot send customized notifications by itself.
