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.

  How Does Windowing Work in Azure Stream Analytics? Introduction Azure Stream Analytics is a powerful tool for real-time data processing that allows organizations to analyze and act on data as it flows in. One of its most essential features is windowing, a method used to break continuous data streams into smaller, manageable chunks. This approach enables users to generate time-based insights, detect patterns, and perform accurate aggregations, making it a cornerstone for real-time analytics and decision-making. How Does Windowing Work in Azure Stream Analytics? What Is Windowing in Azure Stream Analytics? Windowing is a technique used to divide an endless stream of incoming data into defined time intervals, known as "windows." These windows make it possible to analyze data over short periods, such as calculating the number of transactions every 5 minutes or detecting a trend over the last 10 seconds. Microsoft Azure Data Engineer Without windowing, it would be n...
