Question

In order to implement best practices when dealing with a 'Single Point of Failure,' you should attempt to build as much automation as possible in both detecting and reacting to failure. Which of the following AWS services would help?

1) Amazon CloudWatch
2) Amazon S3
3) Amazon RDS
4) Amazon EC2

Answer 1

Amazon CloudWatch and Amazon EC2 are AWS services that help automate the detection and recovery from a Single Point of Failure by enabling monitoring, alerts, and scaling.

Step-by-step explanation:

When addressing a 'Single Point of Failure' (SPOF) within AWS, it is critical to use services that enable monitoring, alerts, and automatic recovery or failover processes. Among the services listed, Amazon CloudWatch is specifically designed for monitoring AWS environments and can trigger alarms and actions based on specific events or metrics, making it an essential tool in automating both the detection of and reaction to failures. Amazon EC2 instances can be set up with Auto Scaling and Elastic Load Balancing to ensure automatic recovery and scaling to handle failures and load, reducing the risk of SPOF. Although Amazon S3 and Amazon RDS are highly available and durable storage options, they do not themselves provide the kind of automated failure detection and recovery directly mentioned in the question. Therefore, to implement best practices for handling SPOF, CloudWatch, alongside features available within the EC2 service, would be most beneficial.
