Software as a Service (SaaS) is a popular business model which allows businesses to work more efficiently, empowering it to be more productive and making enterprises more competitive. Perhaps, you would like to know how it is helping businesses, why so many organizations progressively adopting it and how to build a SaaS app for you? Let’s understand SaaS Application Development together!

Software as a Service (SaaS) is a dominant business model in which businesses host and license their software from a cloud-based server on a subscription basis. Nowadays, the SaaS market is growing fast and is expected to hit the approx US $307.3 billion in 2026.

Software-as-a-service is a popular cloud-based software licensing or subscription model in which you can access your organization’s data anytime, anywhere from any device connected to the Internet.

What is a SaaS application?

Software is delivered to the end-users as a service, and users do not need to install the software and maintain or update the server. SaaS stands for “software as a service”, which refers to the cloud-hosted applications and users can access them using any device.

The software tools like Dropbox, Google Docs, Canva, etc, in essence, are SaaS platforms. Let’s see what sets SaaS applications apart from traditional software:

  • Subscription

You need to subscribe to cloud-based applications; you are not required to purchase a license to use them on a software-as-a-service basis. Application vendors charge you a subscription fee for a full set of its features. You have the choice to subscribe to it yearly, half-yearly, or perhaps monthly.

  • Access

Since these apps are deployed in cloud infrastructure so you can access them using a web interface or a mobile device from everywhere you go.

  • Updates

You do not require purchasing a new SaaS app version every time the app development team releases an update. There are regular upgrades and updates launched by development without interfering its core functionality and affecting user experience.

Comparison of SaaS Software vs. Traditional Software

Lets’ understand the difference between SaaS and traditional apps using an example of – A popular product Adobe Photoshop which has recently adopted the SaaS model. Years ago, users need to buy Adobe Photoshop along with many other programs for a one-time price. Once the product is purchased, users were given an unlock key to access a specific version of Photoshop for a lifetime.

However, if you try to purchase the latest version of Photoshop on Adobe’s website, you will get to know that Adobe offers its product on a subscription basis to the users. You need to sign up for a monthly subscription instead of paying a high up-front cost and you can access the most recent version of multiple adobe products including instant updates. The monthly fee is comparatively low than that of the one-time purchase price of the old model.

Despite the pushback against the subscription way, the SaaS Application Development is on the boom because of its advantages for both developers and users.
