A user is using the AWS EC2. The user wants to make so that when there is an issue in the EC2 server, such as

instance status failed, it should start a new instance in the user-s private cloud. Which AWS service helps to achieve this automation?

A. AWS CloudWatch + Cloudformation

B. AWS CloudWatch + AWS AutoScaling + AWS ELB

C. AWS CloudWatch + AWS VPC

D. AWS

CloudWatch + AWS SNS

Explanation:

Amazon SNS can deliver notifications by SMS text message or email to the Amazon Simple Queue Service (SQS) queues or to any HTTP endpoint. The user can configure a web service (HTTP End point) in his data cen

ter which receives data and launches an instance in the private cloud. The user should configure the CloudWatch alarm to send a notification to SNS when the -StatusCheckFailed- metric is true for the EC2 instance. The SNS topic can be configured to send a

notification to the user-s HTTP end point which launches an instance in the private cloud.
