What is Azure Functions?
Azure Functions is a serverless computing service. It allows you to run small pieces of code. These pieces of code are called “functions.” You do not need to manage servers.
Key Features
• Event-driven execution
• Supports multiple languages (Python, C#, JavaScript)
• Scales automatically
• Pay only when code runs
Simple Example
When a file is uploaded, a function processes it automatically. This is common in data pipelines taught in Microsoft Azure Data Engineering Course programs.
What is Logic Apps?
Logic Apps is a workflow automation service. It helps you create workflows using a visual designer. You do not need to write much code.
Key Features
• Drag-and-drop workflow builder
• 1000+ connectors (like Outlook, SAP, SQL)
• Easy integration across services
• Built-in monitoring
Simple Example
When you receive an email, save the attachment to cloud storage automatically. This is easy with Logic Apps.
Azure Functions vs Logic Apps: Key Differences
Feature Azure Functions Logic Apps
Type Code-based Visual workflow
