Architecture

Multi-Cloud Application Architecture

A serverless reference architecture for distributing applications across Azure and AWS while maintaining consistent delivery practices.

In a dynamic cloud landscape, flexibility and redundancy are essential. This reference architecture uses a serverless framework to support multi-cloud resilience and consistent data flow across Azure and AWS.

Request and response flow

User applications connect to a gateway application, which distributes requests between Azure and AWS. This dual-cloud design supports higher availability and fault tolerance. Responses are routed through a common API management layer to maintain a consistent user experience.

The serverless foundation

At the center of the architecture, the Serverless Framework simplifies deployment and infrastructure management. A manifest-based approach enables teams to deploy serverless workloads across cloud providers while supporting GitOps practices.

Azure integration

The design combines Node.js, Azure Functions, and a multi-cloud library. The Azure Functions Serverless Plugin extends the framework for Azure workloads, supporting a development experience comparable to AWS Lambda.

CI/CD with GitOps

GitOps drives builds, testing, and deployment across both cloud environments. This creates an automated, quality-controlled release path while improving developer productivity and operational consistency.

Use cases and deployment resilience

Teams can use this approach to write cloud-agnostic APIs, deploy microservices across providers, and maintain a consistent development workflow. Duplicate microservice sets can support blue-green or active-passive deployment patterns, improving availability and reducing release risk.
