Using Azure Functions to Build Your First Serverless Application

The tutorial provides a comprehensive guide on building and deploying a serverless application using Azure Functions, focusing on creating a coin flip game that leverages Azure's ecosystem, including Cosmos DB for state management and Application Insights for monitoring. It walks through setting up the necessary environment, defining serverless functions for game session creation, joining, and state management, and deploying these functions using Azure Function Core Tools or CI/CD pipelines on GitHub. The tutorial emphasizes security measures such as using function keys and CORS, and highlights the benefits of serverless architecture, including reduced server management and cost-efficiency, as functions are only executed when triggered. Additionally, it introduces Earthly, an open-source tool to streamline CI/CD processes, offering improved build times through containerization and caching.
