Prefect

Prefect is a modern data workflow orchestration platform for scheduling and monitoring Python-based pipelines. Its standout trait is a hybrid execution model where the control plane never sees your data or code, only execution metadata.

βš™ Full Stack

A Python-based orchestration server exposing a REST API and UI, backed by PostgreSQL for flow-run state, with independent worker processes polling for scheduled work and executing it wherever they're deployed (k8s, ECS, local).

πŸ“ˆ Scaling Analysis

The server/API tier is largely stateless and the actual flow execution is fully decoupled onto horizontally scalable worker pools, which is a clean scaling story β€” the main constraint is the single Postgres instance for orchestration metadata under very high flow-run volume.

πŸš€ Running on Nexlayer

Deploy the Prefect server as one pod with a Postgres pod at <podName>.pod:5432, and run workers as a separately scaled deployment/pod pool; workers only need outbound access to the server API, no inbound ports. Official images pull cleanly through mirror.gcr.io.
