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 centre 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.
