What is SaaS

SaaS or Software as a Service means software delivery and maintenance via a subscription model. A SaaS product is hosted in the cloud, which means it does not need to be installed on a computer and is not sold with a lifetime license.

Users of such software do not have to deal with complicated configurations or updates. They always have access to the newest versions of the software. Such programs can be used anywhere in the world, from any device and web browser even without an internet connection. A great example of a Software as a Service business model is Adobe’s Creative Cloud - which moved from traditional software to a SaaS model.

SaaS offers benefits like:

Security - cloud service providers ensure maximum security of data
Cost efficiency - no need to buy and maintain hardware
Reliability - servers can be located around the world so even if one of them goes down, the app will remain online
Scalability - you can upgrade or downgrade your plan with a few simple clicks according to your requirements
What is more, a SaaS-based application can be used on multiple devices (including mobile devices) with a single login, contrary to traditional software. Users also usually have the opportunity to test the software before buying the subscription which is a significant advantage.
