AWS CloudWatch is a service designed specifically for monitoring and observing application performance as well as infrastructure metrics within the AWS ecosystem. CloudWatch enables real-time monitoring of resource utilization, application performance, and operational health through the collection and tracking of metrics, logs, and events.

One of its key functionalities is the creation of dashboards to visualize metrics and set alarms to notify users when thresholds are crossed. This ensures that potential issues can be identified and addressed proactively, optimizing application performance. Additionally, CloudWatch allows users to create custom metrics and includes features such as Application Insights for deeper monitoring of application performance, which is essential for maintaining highly available and reliable applications.

The other options serve different purposes within the AWS ecosystem; for example, AWS CloudFormation is a service focused on deploying and managing infrastructure as code, while AWS Lambda supports serverless computing by allowing users to run code without provisioning or managing servers. AWS Step Functions is used for coordinating multiple AWS services into serverless workflows, which helps in application management but does not directly provide application performance monitoring.
