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 SNStopic can be configured to send a notification to the user’s HTTP end point which launches an instance in the
private cloud.
I think the answer is B.
D is correct, SNS send messages to the client who can do something in this private cloud.
Keywords here are New instance in “Users Private Cloud”. Cloud Formation, VPC, Autoscaling can’t manage or control off site private clouds owned by users. So assuming the user has everything setup correctly, CloudWatch+SNS. Answer is D.
These questions are sometimes tricky. Take the time to read them.
Perfect!
