Serverless APIs with Azure Functions and Cosmos DB

Modern application development requires speed, scalability, and minimal infrastructure management. Combining serverless computing with a flexible NoSQL database allows you to build highly responsive systems without the overhead of server maintenance. In this text-based course, you will learn how to design, write, and deploy serverless APIs using Azure Functions and Cosmos DB. You will transition from understanding core cloud concepts to constructing fully functional, event-driven backend systems. Through clear written explanations and structured code snippets, you will master the mechanics of triggers and bindings to automate data flows seamlessly. What you'll learn: - Understand the fundamentals of serverless architecture and cloud-native design. - Configure HTTP triggers, timers, and database-driven events to execute your code. - Implement input and output bindings to read and write database records with minimal code. - Structure and query JSON documents within Cosmos DB container environments. - Manage application settings, environment variables, and connection strings securely. - Log, monitor, and troubleshoot serverless execution flows. You will begin by exploring foundational cloud terminology, setting up your local development environment, and writing basic functions. From there, you will progress through practical written exercises that demonstrate how to connect your code to database containers, handle live data streams, and secure your API endpoints. This course is designed for beginner developers, backend enthusiasts, and software engineers looking to transition to serverless architectures. No prior experience with cloud providers or NoSQL databases is required. Start reading today to build your first event-driven serverless backend.
