Azure Functions Overview

What are Azure Functions?

Azure Functions is a serverless compute service that lets you run code on-demand without explicitly provisioning or managing infrastructure. It's event-driven, meaning your code runs in response to a specific event, such as an HTTP request, a timer, or a message arriving in a queue. This allows you to build applications and services that react to events, process data, and integrate systems without worrying about the underlying servers.

Key Benefits

• Serverless Architecture: No infrastructure management required. Focus on writing code.
• Event-Driven Execution: Respond instantly to events from various Azure services and external sources.
• Automatic Scaling: Handles fluctuating workloads seamlessly, ensuring performance and availability.
• Multiple Language Support: Develop in your preferred language, including C#, F#, Java, JavaScript, PowerShell, Python, and TypeScript.
• Integration: Easily integrate with other Azure services and third-party applications using triggers and bindings.
• Cost Efficiency: A pay-as-you-go model that is cost-effective for event-driven workloads.

Common Use Cases

Azure Functions are ideal for a variety of scenarios:

• Web APIs: Build lightweight RESTful APIs.
• Real-time Data Processing: Process data from IoT devices, streaming services, or databases.
• Background Tasks: Schedule tasks to run at specific intervals or in response to events.
• Orchestration: Coordinate complex workflows involving multiple services.
• Microservices: Develop and deploy individual microservices.
