What is Software as a Service (SaaS)?

SaaS refers to using software applications online without downloading the application programs on your computers. It is similar to leasing an apartment that comes with furniture without ownership.

Users can simply access the software via a web browser and pay a subscription fee. Examples of SaaS services include Gmail, MS Office tools like Word, Excel, and PowerPoint, among others, and Salesforce for businesses of all sizes.

Software as a Service (SaaS) is software hosted and maintained by a provider, accessible via the Internet on a subscription basis. 

Unlike traditional software installed locally, SaaS applications are accessed through a web browser, removing the need for users to handle installation, maintenance, or updates themselves. For instance, in Google Workspace, Gmail and Google Docs tools are offered as SaaS, where users can use them online and do not require installation.

On the other hand, traditional software is bought with a perpetual license and installed on local computers or servers. Users are responsible for managing updates and backups. For example, Adobe Photoshop is launched and updated individually on each computer and its components.
