A company runs its applications on a large number of Amazon EC2 instances. A SysOps administrator must implement a solution to notify the operations team whenever an EC2 instance state changes.
What is the MOST operationally efficient solution that meets these requirements?
The most operationally efficient solution is to create an Amazon EventBridge event rule that captures EC2 instance state changes and set an Amazon Simple Notification Service (Amazon SNS) topic as the target. This approach avoids unnecessary complexity and additional steps, ensuring that notifications are sent directly to the operations team with minimal configuration and overhead.
It's B, you don't need a Lambda to send a notification from Eventbridge.
C. is not suitable due to lambda adding an extra step that answer B. already does efficiently
B it's the simplest
B. Create an Amazon EventBridge event rule that captures EC2 instance state changes. Set an Amazon Simple Notification Service (Amazon SNS) topic as the target
instance stage change-> eventbridge rule-> target SNS topic
B is best answer
Answer: B https://repost.aws/knowledge-center/ec2-email-instance-state-change
notify --> has SNS --> remove A, choose B,C or D. --> Most operationally efficient. --> state change --> event --> state A to state B, state B to state A, state B to state G --> EventBridge --> choose B or C. --> C has AWS Lamba (not necessary) --> Choose B.
