Cloud Concepts

This page describes the high-level concepts of the LangGraph Cloud deployment.

Deployment

A deployment is an instance of a LangGraph API. A single deployment can have many revisions. When a deployment is created, all of the necessary infrastructure (e.g. database, containers, secrets store) are automatically provisioned. See the architecture diagram below for more details.

See the how-to guide for creating a new deployment.

Revision

A revision is an iteration of a deployment. When a new deployment is created, an initial revision is automatically created. To deploy new code changes or update environment variable configurations for a deployment, a new revision must be created. When a revision is created, a new container image is built automatically.

See the how-to guide for creating a new revision.

Asynchronous Deployment

Infrastructure for deployments and revisions are provisioned and deployed asynchronously. They are not deployed immediately after submission. Currently, deployment can take up to several minutes.

Architecture

!!! warning "Subject to Change" The LangGraph Cloud deployment architecture may change in the future.
