Cloud Run

language

description Cloud Run Overview

Cloud Run provides a serverless container execution environment on Google Cloud. It allows developers to run stateless applications packaged as Docker containers without needing to manage servers or infrastructure scaling. This platform is suitable for web applications, APIs, and event-driven processes, primarily benefiting those seeking simplified deployment and automatic scaling of containerized workloads.

help Cloud Run FAQ

What is the difference between Google Cloud Run and Google App Engine?

Google Cloud Run is a fully managed compute platform that deploys stateless containers, giving developers complete control over their runtime and environment. App Engine, on the other hand, is more rigid and requires developers to adhere to specific language-specific 'runtimes' rather than bringing a custom Docker container.

Does Cloud Run support background tasks?

Cloud Run is designed specifically to run stateless containers that respond to HTTP requests or Cloud Events, meaning it expects instances to finish their requests quickly. While it can handle out-of-band requests, running heavy, persistent background tasks is generally discouraged in favor of services like Cloud Tasks or GKE.

Can Cloud Run scale to zero?

Yes, one of the primary features of Cloud Run is its ability to scale to zero when there are no incoming requests. This means you are not charged for compute time when the container is idle, making it highly cost-effective for low-traffic applications.

How does Cloud Run handle stateless applications?

Because Cloud Run focuses entirely on stateless containers, any local memory or session data stored within a container instance is not persisted across requests or instances. Developers must rely on external databases like Cloud SQL or Firestore to manage persistent user data and application state.
