Summary

This chapter examined how serverless computing revolutionizes microservices development by providing a highly agile, cost-efficient, and scalable alternative to traditional hosting models. It explained how Azure Functions and Durable Functions can be applied to real-world domains such as healthcare systems, where workflows require both efficiency and resilience. The discussion balanced the benefits of serverless architectures with their inherent challenges, offering practical strategies, patterns, and examples for .NET developers.

We emphasized that designing for serverless requires more than just migrating existing workloads into a new environment. Function granularity is a key design decision: functions should adhere to the single responsibility principle, be cohesive, and avoid excessive chaining, which can cause latency and tracing challenges. We also highlighted naming conventions and dependency injection practices, paying particular attention to the isolated worker...
