Hello. Does anyone know how to deploy a stack to several regions so that the application works as quickly as possible for users around the world?

export default function main(app: <http://sst.App|sst.App>): void {
  app.setDefaultFunctionProps({
    runtime: "nodejs14.x",
  });

  for (const region of ["us-west-1", "eu-central-1"]) {
    new CoreStack(app, "core-stack", { env: { region } });
  }
}

Will that be enough? Or should I create a new stack for each region and share all parts of the main one? https://docs.serverless-stack.com/constructs/Api#sharing-an-api-across-stacks Do I need to use load balancer? https://docs.serverless-stack.com/constructs/v1/Api#apialbrouteprops

for SST, you must deploy multiple times using the

--region

param for the CLI. You can use the current deploying region in the app/stacks though, to choose which parts to deploy in each region. Multi or single is up to you past that point.
