What service does Amazon CloudWatch provide?

Amazon CloudWatch provides monitoring and observability for AWS resources and applications. It enables users to collect and track metrics, collect log files, and set alarms, making it a vital tool for gaining insight into the performance and operational health of AWS services and resources. This capability allows organizations to understand system performance, troubleshoot operational issues, and optimize resource use effectively.

The service's monitoring features include the ability to visualize and analyze logs and metrics in real time, which aids in proactive management of applications and infrastructure. By using CloudWatch, teams can maintain operational excellence, ensuring that systems run smoothly and efficiently.

The other options mention services that do not align with the core functionality of Amazon CloudWatch. For instance, real-time data streaming is associated with Amazon Kinesis, and automated call distribution pertains more to contact center solutions rather than monitoring services. Network performance tracking is typically related to services like AWS Global Network or third-party monitoring tools, not directly part of CloudWatch's primary features.
