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.

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 datacenter 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.

private cloud doesnt mean virtual private cloud.
