Cloudflare Workers is a serverless computing platform provided by Cloudflare, a global content delivery network (CDN) and cybersecurity company. It allows developers to deploy and run code at the edge of Cloudflare's network, closer to end-users, rather than in traditional data centers or cloud servers.
Cloudflare Workers operate on a serverless model, meaning developers don't need to manage the underlying infrastructure. The platform automatically scales based on demand. Programming is done using Javascript, and execution is pushed to Cloudflare edge locations, reducing latency for the applications. Cloudflare Workers can be used for a variety of tasks, including serverless computing, dynamic content generation, API handling, security enhancements, and more.
Serverless functions can be combined into a complex systems which become difficult to troubleshoot or test. OpenTelemetry and distributed tracing is used to simplify the troubleshooting of complex, cloud native applications, and can be applied to Cloudflare workers. This provides instrumentation and the ability to visualize the complete call path through your serverless application. Trace-based testing with Tracetest can leverage this visibility to allow you to create and run tests against your service. You can do this testing in a totally serverless environment with Tracetest.
