This session explores how .NET Aspire streamlines the development of polyglot microservices through a real-world e-commerce case study inspired by the architecture from the .NET Aspire Book. Attendees will learn how to orchestrate a distributed system composed of a React frontend, a .NET-based Warehouse API, a Go-powered Create Order API, a Python Payment API, and a Node.js Shipping API-all seamlessly integrated using Aspire’s unified tooling. We’ll demonstrate how to coordinate order processing workflows across languages using a pub/sub pattern with Redis for local development and Azure Service Bus in production. The session covers strategies for centralized observability, consistent database management via Data API Builder, and cloud-agnostic deployment. Through live demos, participants will see how Aspire enables rapid local debugging, automated service wiring, and resilient scaling, making it dramatically easier to build, test, and operate robust, production-grade microservices architectures with diverse technology stacks.
