SaaS
Abbreviation for Software as a Service
In short and in plain language
SaaS is software that you use over the internet in your browser.
You do not have to install it yourself. You usually pay for it on a regular basis, such as every month.
What often matters here is how fast the software reacts after you log in.
Definition
SaaS refers to software that a provider offers over the internet and that customers use in the browser instead of installing it. It is usually paid for on an ongoing basis, for example as a monthly subscription. For load time, what often matters there is how quickly the interface and data respond after login.
