Adam Michael Wood is discussing Amazon Simple Storage Service (S3), a highly scalable object store that allows files to be uploaded and retrieved through various interfaces. S3 is ideal for storing web assets, static site hosting, backup and recovery, archiving, and general-purpose file storage due to its unlimited capacity and up to 5 terabytes per object size. Datadog provides an integration with S3, collecting and visualizing metrics such as throughput, error, performance, and resource usage, allowing for in-depth monitoring and actionable insights. To use the integration, users need to install the main AWS integration and enable S3 metric collection, which can be correlated with other AWS services like CloudFront for full visibility into web resources.
