Any service offered over the Internet is a form of Web Application.
For example, MS Office 365, disk storage, shopping carts, video streaming, social media and AI applications.
Simple web applications providing static content are called websites. They may act as business card for your company, whereas complex and interactive solutions are called web applications.
