Efficient Ways to Reduce AWS Costs

Answer - A and B.

You can use Cloudwatch alarms to see if resources are below a threshold for long periods of time.

If so, you can decide to either stop them or terminate the resources.

In the Trusted Advisor, when you enable the Cost optimization section, you will get all sorts of checks which can be used to optimize the costs of your AWS resources.

To optimize the costs incurred by resources running in AWS, there are several options that can be considered. Two possible answers to this question are:

A. Create Cloudwatch alarms to monitor underutilized resources and either shutdown or terminate resources that are not required. B. Use the Trusted Advisor to see underutilized resources.

Option A: Create CloudWatch alarms to monitor underutilized resources and either shutdown or terminate resources that are not required.

CloudWatch is a monitoring service provided by AWS that can be used to collect and track metrics, collect and monitor log files, and set alarms. By creating CloudWatch alarms to monitor underutilized resources, it is possible to detect when a resource is not being fully utilized and to either shut it down or terminate it. This can help to reduce costs by eliminating unnecessary resources.

For example, if an EC2 instance is running but not receiving any traffic, it may be underutilized. A CloudWatch alarm can be set up to detect this and automatically shut down the instance after a certain period of time.

Option B: Use the Trusted Advisor to see underutilized resources.

The Trusted Advisor is a tool provided by AWS that provides real-time guidance to help optimize AWS resources, improve security and performance, and reduce costs. The Trusted Advisor provides recommendations based on best practices in five categories: cost optimization, performance, security, fault tolerance, and service limits.

One of the recommendations provided by the Trusted Advisor is to identify and terminate underutilized resources. By using the Trusted Advisor to see underutilized resources, it is possible to quickly identify which resources are not being fully utilized and take action to reduce costs.

Overall, both options A and B are valid ways to optimize costs in AWS. However, it is important to note that there are other ways to optimize costs in AWS, and the best approach may vary depending on the specific situation. It is also important to consider factors such as performance, security, and scalability when optimizing costs.
