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.
Is this a poorly structured question or is it me 🙂
The answer could be B, even though there is no clue in the question that ELB should be involved
The explanation points to D, even though there is no clue in the question that SQS is in play

“..it should start a new instance in the user’s private cloud”
Since AWS can’t be used to launch a new instance in users private cloud using SNS to notify an external endpoint makes most sense. I dont think A,B or C will help launch an instance in non-AWS cloud 😉
