It's impossible to avoid SaaS nowadays. We do this routinely as part of our regular schedule. If you logged into Gmail today or paid a monthly fee to Netflix, you are using the software as a service. — As the name implies, SaaS (Software-As-A-Service) provides users with software applications as a service. Instead of downloading the software application to your device as an offline application, you access it via the internet using your browser. In other words, you can't use a SaaS application unless you have internet access.
