What purpose does Amazon CloudWatch serve?

Amazon CloudWatch is primarily designed to monitor resources and applications within the AWS ecosystem. It serves as a crucial monitoring and observability service that provides you with real-time insights into resource utilization, application performance, and operational health. This monitoring capability allows users to collect and track metrics, set alarms, and automatically react to changes in the system.

CloudWatch plays an essential role in enabling users to visualize their AWS resource metrics through dashboards, allowing for a consolidated view of system performance. It supports proactive management by enabling alerts based on certain thresholds, helping users to ensure that their applications are running optimally and efficiently.

The functionality of CloudWatch goes beyond mere monitoring; it integrates with other AWS services to facilitate automated responses to operational changes, thus enhancing the overall reliability and performance of applications running in the cloud.

In contrast, other options related to provisioning, deploying, or transferring data reflect functionalities that are served by different AWS services. For example, resource provisioning is typically handled by services like AWS CloudFormation or the AWS Management Console, while serverless application deployment falls under AWS Lambda and related services. Data transfer between regions is managed using services such as AWS DataSync or Amazon S3 Transfer Acceleration, rather than CloudWatch. Therefore, the correct understanding of Amazon CloudWatch
