Through cloud computing, anything can be accessed through the internet. If someone doesn't have a good GPU to play games, he can play those games online. He does not need a PC because it can be run on a mobile device. Not only that, if I am building an application and my PC does not have the power to compile it, then cloud computing will be the solution. Even if someone needs to train a large amount of data for machine learning, cloud computing can provide all the resources you want and train the data for you. Also, in many cases, running some applications on the local machine might be dangerous, or if I want to test the thing in a different environment, I can do that using cloud computing. Not to mention, most people use cloud computing to host a website or application.
