Why move video rendering from the web server to a cloud worker?

Why move video rendering from the web server to a cloud worker?

Video rendering can consume substantial CPU, memory, and time. A worker lets the web application accept a request and track its progress without keeping the browser request responsible for the entire render.

Separate responsibilities

The API validates input and ownership, creates a job, and dispatches work. The worker retrieves trusted job data, processes media, saves output, and updates state. The portal reads that durable state. A worker is an architectural role; Google Cloud offers different execution products, and the appropriate choice depends on the workload.

Account for the new boundary

Remote execution introduces authentication, retries, deployment configuration, and observability needs. A queued request is not a completed video. Test delayed start and worker failure before assuming the separation makes the system reliable. Keep local fixtures so rendering can be diagnosed independently of cloud dispatch.
