1) Amazon CloudWatch
2) Amazon S3

Answer 1

Amazon CloudWatch is the AWS service that allows you to monitor the performance of your EC2 instances.

Step-by-step explanation:

The AWS service that allows you to monitor the performance of your EC2 instances and troubleshoot issues is Amazon CloudWatch.

Amazon CloudWatch provides monitoring and observability for your AWS infrastructure resources, including EC2 instances. It collects and tracks metrics such as CPU utilization, network traffic, and disk usage. With CloudWatch, you can set up alarms to notify you when certain thresholds are exceeded, helping you identify and resolve performance issues.

For example, you can create a CloudWatch alarm to notify you when the CPU utilization of your EC2 instance goes above a certain percentage, indicating a potential bottleneck. This allows you to take proactive measures to optimize your application's performance.
