The article explores the concept of serverless architecture, specifically focusing on Azure Functions, which are event-driven and execute code in response to triggers such as webhooks or HTTP requests. Serverless provides benefits like automatic scaling, cost efficiency, and reduced maintenance for applications with variable demand or infrequent usage, but it may not be suitable for applications requiring constant running or quick response times due to potential cold start issues. The article provides a practical guide to creating and deploying serverless functions using Visual Studio Code and the Azure Functions extension, detailing the process from setting up a local environment to publishing on Azure. It highlights the advantages of using infrastructure as code for deploying Azure Functions, emphasizing the repeatability and customization it offers, despite seeming more complex than using the Visual Studio Code extension or Azure CLI. The text concludes by encouraging readers to experiment with creating Azure Functions in different languages to understand the process better, and it teases a future exploration of Azure static websites.
