Modern applications consist of a wide array of frontend applications, backend services, and dependencies deployed across hosts, containers, and serverless infrastructure. Without end-to-end observability into an environment, triaging an issue becomes a slow and arduous process. In this workshop, you will instrument an application with Datadog APM. Then, you’ll use Distributed Tracing to identify issues with the application and improve the user experience. Once the application is functioning as expected, you will put measures in place to make sure you are alerted if latency increases above a threshold.
