AWS multi-region

To deploy resources to multiple AWS regions, you can create a new provider for the region you want to deploy to.

sst.config.ts

const provider = new aws.Provider("MyProvider", { region: "us-west-2" });

And then pass that in to the resource.

sst.config.ts

new sst.aws.Function("MyFunction", { handler: "index.handler" }, { provider });

If no provider is passed in, the default provider will be used. And if no region is specified, the default region from your credentials will be used.

sst.config.ts

const east = new sst.aws.Function("MyEastFunction", {
  url: true,
  handler: "index.handler",
});

const provider = new aws.Provider("MyWestProvider", { region: "us-west-2" });
const west = new sst.aws.Function(
  "MyWestFunction",
  {
    url: true,
    handler: "index.handler",
  },
  { provider }
);

index.ts

export async function handler() {
  return {
    statusCode: 200,
    body: `Hello from ${process.env.AWS_REGION}`,
  };
}
