Which AWS service makes it easier to monitor and troubleshoot application logs and cloud resources?

Explanations:

Amazon EC2 is a virtual server service that provides compute capacity in the cloud, but it does not specifically offer monitoring or troubleshooting capabilities for application logs or cloud resources.

AWS Identity and Access Management (IAM) is used for managing user access and permissions, not for monitoring or troubleshooting application logs or resources.

Amazon CloudWatch is a monitoring and management service that provides data and insights for AWS resources and applications. It collects and tracks metrics, monitors log files, and sets alarms, making it essential for troubleshooting and monitoring.

AWS CloudTrail is a service that records AWS API calls for your account, providing visibility into user activity. While it helps in security and compliance, it is not primarily focused on monitoring application logs or resources in real-time.
