description Google Cloud Workflows Overview
Google Cloud Workflows is a serverless orchestration service for connecting Google Cloud services and external APIs. It allows developers to define workflows in YAML or JSON, making it highly portable and easy to version control. It excels at managing long-running processes that require reliable state management and error handling. For organizations heavily utilizing GCP, this provides a native way to orchestrate complex backend tasks without managing infrastructure.
help Google Cloud Workflows FAQ
How long can a Google Cloud Workflow wait for an external process?
A workflow can hold state, sleep, poll, retry, or wait for up to one year. Because Workflows is serverless, an idle workflow does not require a continuously running virtual machine.
Should a workflow definition be written in YAML or JSON?
Google Cloud Workflows accepts definitions in either YAML or JSON using the same underlying workflow syntax. YAML is often easier for humans to edit, while JSON may fit tooling that already generates structured configuration.
How is Google Cloud Workflows priced?
Charges are based on executed steps, with separate rates for internal Google Cloud steps and external calls. The monthly free allowance includes 5,000 internal steps and 2,000 external steps, after which usage is billed in 1,000-step increments.
When should I use Workflows instead of Cloud Composer or Cloud Run?
Workflows is suited to orchestrating Google Cloud services, Cloud Run endpoints, and HTTP APIs with explicit steps, retries, and state. Cloud Composer is aimed at Apache Airflow data pipelines, while Cloud Run is better for executing custom application code and libraries.
