Simultaneous multi-cloud deployment to AWS and GCP with CircleCI

AWS recently faced a major outage that disrupted services like McDonald's mobile ordering and some Netflix features, highlighting the risks of relying on a single cloud platform. The text discusses the benefits of a multi-cloud strategy, which offers advantages such as redundancy, geographic optimization, cost flexibility, and avoiding vendor lock-in. It illustrates a scenario where a startup uses both AWS for US operations and Google Cloud Platform for EU operations to meet compliance requirements. The document provides a tutorial on setting up a multi-cloud deployment pipeline using CircleCI to deploy a Node.js application to both AWS ECS Fargate and Google Cloud Run, emphasizing cloud-agnostic CI/CD practices. This includes steps for creating a unified deployment pipeline, handling cloud-specific authentication, managing environment-specific configurations, and implementing parallel deployments. It also covers setting up infrastructure using infrastructure as code, configuring IAM roles and policies, and verifying deployment success on both AWS and GCP. The tutorial emphasizes the strategic flexibility and operational resilience offered by multi-cloud deployments, allowing organizations to leverage the strengths of different cloud providers.
