The service that provides a record of CloudTrail events from the past 90 days is CloudTrail event history. This feature allows users to access and review the last 90 days of management and data events captured by AWS CloudTrail. It is designed specifically for retrieving and analyzing various API calls made within your AWS account specific to different services.
CloudTrail event history facilitates monitoring and auditing activities by providing accessible visibility into actions taken by users, services, or roles within the AWS ecosystem. This capability is crucial for security and compliance purposes, as it allows administrators to track changes and access patterns, making it easier to identify potential issues or unauthorized activity.
In contrast, the other services listed do not provide historical records of CloudTrail events. Amazon CloudWatch Logs focuses on monitoring and storing logs generated by AWS resources, but does not specifically capture CloudTrail event history. Amazon EventBridge serves as a serverless event bus service that lets you connect applications using events, and AWS Config provides configuration history for AWS resources but not the specific API call history that CloudTrail event history offers.
