Building Serverless Microservices on Azure: A Comprehensive Guide to Using Functions, Logic Apps, Event Grid, and Service Bus

As organisations transition from monolithic architectures to microservices, serverless computing offers a scalable, cost-effective way to build, manage, and scale applications without the overhead of managing infrastructure.

Azure provides a suite of serverless tools — Azure Functions, Logic Apps, Event Grid, and Service Bus — ideal for implementing lightweight, decoupled microservices. By leveraging these services and serverless storage solutions like Azure Table Storage and Cosmos DB, organisations can simplify their architecture, reduce costs, and increase deployment speed.

In this guide, we will explore each of these Azure serverless tools, compare them to other Azure services, and present a structured plan for designing microservices in a serverless model.

1. Introduction to Serverless Microservices

Serverless compute abstracts infrastructure management, allowing developers to focus on application logic rather than underlying hardware. This approach is well-suited for microservices, where individual services need to be independent, scalable, and cost-efficient.
