The integration of Amazon S3 Storage Lens with Datadog enhances the ability to monitor and optimize S3 storage across multiple AWS accounts and regions. By leveraging S3 Storage Lens metrics through Datadog's dashboard, users can gain detailed insights into storage trends, cost efficiency, and data protection practices. The dashboard facilitates granular analysis by allowing filtration of metrics by various parameters such as AWS organization, account, and region, thereby helping organizations understand changes and trends in S3 usage. Cost optimization is achieved by identifying non-current object versions and incomplete uploads that can be deleted, and by utilizing efficient data retrieval methods like Amazon S3 Select. Furthermore, the integration supports data protection by providing a summary of encrypted, replicated, and protected storage, allowing users to configure alerts for any deviations. It also aids in maintaining continuous visibility and security of S3 data, suggesting steps that align with AWS best practices for data protection. Users can begin utilizing this integration with a straightforward setup process, enhancing their S3 management capabilities.
