Amazon CloudWatch is the service designed for monitoring applications in real-time within the AWS ecosystem. It provides a comprehensive suite of tools to collect and track metrics, logs, and events. By using CloudWatch, you can set up alarms to notify you about changes in your AWS resources and applications, enabling proactive management and quick responses to any operational issues.

CloudWatch allows you to visualize the performance of your applications through dashboards and offers the ability to monitor custom metrics, ensuring that you can tailor your observations to the specific needs of your applications. Its integration with other AWS services allows for a seamless monitoring experience, making it a pivotal tool in ensuring application performance and availability.

The other services mentioned serve different purposes. For instance, Amazon RDS manages database instances and does not provide application monitoring capabilities. AWS Trusted Advisor focuses on best practices for AWS accounts, offering recommendations on cost optimization, performance, security, and fault tolerance. AWS Config is primarily used for assessing, auditing, and evaluating the configurations of your AWS resources rather than real-time application monitoring.
