What characterizes Software as a Service (SaaS)?

Software as a Service (SaaS) is characterized primarily by its delivery model, which involves accessing software applications over the Internet rather than having them installed locally on a user's hardware. This model enables users to leverage the software via a subscription fee, which may vary based on usage or access levels. The fact that SaaS applications are managed centrally by service providers means that users do not need to worry about hardware installation or maintenance, making them more accessible and easier to use.

Furthermore, the subscription model often provides flexibility for users, as they can scale their usage up or down based on their needs without the traditional constraints of purchasing software licenses or hardware upgrades. SaaS applications are widely used across various industries and are available to both individuals and businesses, making them a popular choice for deployment in today's digital environment.
