Deployment Models & Regions

Overview

When you first create a Stitch application you must select a deployment type that determines where your application’s data is stored and processed. You can deploy your Stitch application globally or limit the deployment to a specific cloud deployment region.

Deployment Models

Global Deployment

Globally deployed Stitch applications are hosted in every cloud region that Stitch supports. The Stitch SDKs automatically execute application requests, such as reading user information or calling a function, in the cloud region that’s closest to the user that issued the request.

Write operations to a linked MongoDB cluster are handled within a single region that you specify when you create your application. By default, Stitch handles writes in the region closest to your application’s original linked MongoDB cluster.

Local Deployment

Locally deployed Stitch applications are hosted in a specific cloud region that you specify when you first create your application. Application requests and MongoDB write operations will all be handled exclusively in the specified region. By default, local applications are deployed in the region that is closest to your application’s initial linked Atlas cluster or us-east-1 if there is no linked cluster.

Cloud Deployment Regions

Stitch supports deployment and writes in the following AWS regions:

  • Virginia (us-east-1)
  • Oregon (us-west-2)
  • Ireland (eu-west-1)
  • Sydney (ap-southeast-2)
