Managing Multi-Cloud Environments with a Single Pulumi Stack

Introduction

Modern microservice architectures frequently reject monolithic cloud dependencies. To optimize operating costs, data residency, and platform capabilities, architectures often distribute components across multiple providers—for example, hosting a frontend on AWS and databases on GCP. Pulumi simplifies cross-platform deployments through unified program states.

Multi-Cloud Implementation in TypeScript

import * as aws from "@pulumi/aws";
import * as gcp from "@pulumi/gcp";

const enterpriseBucket = new aws.s3.Bucket("shared-data-bucket", {
    acl: "private",
    tags: { Environment: "Production" },
});

const crossCloudAccount = new gcp.serviceaccount.Account("aws-reader", {
    accountId: "aws-data-reader",
    displayName: "Identity to read AWS Data Assets",
});

export const bucketArn = enterpriseBucket.arn;
export const gcpAccountEmail = crossCloudAccount.email;
