Web applications(or web apps), which run in the cloud and do not need to be installed on your computer. These are sometimes called cloud apps.
Examples of Web Apps
- Online Email Services: Services like Gmail andYahoo! Mail run within your browser and can do many of the same things that email programs likeMicrosoft Outlook can do. After you sign up for an online email service, you can begin using it immediately - no installation is required. Instead of being stored on your computer, your emails are stored in the cloud.
- Google Docs: Google Docs is an office suite that runs within your browser. Much like Microsoft Office, you can use it to create documents,spreadsheets, presentations, and more. Your documents are stored in the cloud, which makes it easy to share your documents with other people.
- Facebook: Facebook lets you create an onlineprofile and interact with your friends. Profiles and conversations are constantly evolving, so Facebook uses web app technologies throughout the site to keep the information up-to-date. There are also games and other web apps that you can add to your Facebook profile.
- Web apps are becoming more and more integrated with websites, and it may be hard to distinguish between a web application and a "regular" website. In many cases, you may be using a web application without even knowing it!
How Do Web Apps Work?
When you use a web app, you are working from your computer or mobile device, but much of the actual processing is done by a network of servers. These servers can pool all of their processing power in order to handle requests from all over the world. They also use specialized servers to store the data that you're working with, as well as the data from all of the other users. All of this happens very seamlessly, so it looks almost like the application is running on your computer.For example, if you open a document with Google Docs, your web browser will communicate with the network ofservers to display your document. As you edit the document, your browser will work closely with the servers to make sure everything is kept up-to-date.
