Which AWS service provides centralized logging for AWS services?

AWS CloudTrail is the service designed for centralized logging of AWS services. It enables you to monitor and log account activity across your AWS infrastructure by recording API calls made on your account. This logging includes details such as who made the API call, the services used, the actions taken, and parameters associated with the request. CloudTrail makes it easier to track changes and access patterns, which is essential for compliance, auditing, and troubleshooting.

In contrast, other services listed serve different purposes. AWS Systems Manager provides operational data from multiple AWS services to automate tasks across your resources, but it does not specifically focus on centralized logging. Amazon VPC is related to network configuration and management within your AWS environment and does not deal with logging at all. AWS Config is used for resource configuration tracking and compliance assessments, focusing more on the state of resources rather than logging API calls. Thus, CloudTrail is the optimal solution for centralized logging within the AWS ecosystem.
