It seemed for some time that Google’s vision of online apps — Google Docs, Sheets and Slides — was destined to remain a free, lightweight solution to basic apps. Within a short few years, however, we have seen them grow in use and of course, now we have Microsoft’s online apps in the form of Microsoft 365.

1. Definition

Cloud Computing is defined as the on-demand delivery of software services over the Internet. The services range from storage to databases, networking, software, and analytics. Traditionally, applications were installed on the local storage device of a computer. With Cloud Computing, the applications are installed on servers and made available to clients via the Internet. The interface is presented in the client’s browser.

Software as a Service (“SaaS”) is a subset of Cloud Computing.

2. Examples

It seemed to me that for quite some time Google was the leader with its SaaS offering of Google Docs, Sheets, Slides, Forms, Gmail and more, while Microsoft appeared to be clinging to its disk-based solutions. Microsoft 365, launched globally in 2011, offers online versions of Word, Excel, PowerPoint and Outlook which I would say surpass the capabilities of Google’s offerings.

4. Disadvantages

  • The user must be online to work.
  • A broadband connection is needed.
  • Data costs are incurred while you are working.
