Real-world examples of distributed computing
- [Instructor] Distributed computing is important for building high performance web applications. By breaking task into smaller chunks and utilizing multiple threads, we can handle complex operations without freezing the user interface. Let's start with a real world example, an image processing application. Suppose you are building a web app that allows users to apply filters to high resolution images. This task can be extremely resource intensive. In this example, we'll look at how web workers can be used to process image filters efficiently. Here's a basic react setup for an image filter app, where we'll use a web worker to apply a grayscale filter to the image. Let's start by creating our web worker. This worker will handle the image processing in a background thread. In this worker, dot J S file, we define a apply grayscale filter function that processes image data to convert it to grayscale. The worker listens for messages containing image data, processes it, and then sends the…
