SAAS (Software as a Service) Platform Architecture

Throughout the years, numerous different software models started to emerge. One-time software licensing was the ideal choice at first, but nowadays new features and security updates are added often to a software, not to mention some people need to use that software from time to time. That’s how the Software as a Service platforms started to emerge.

What is Software as a Service?

At its core, the idea behind this software licensing and delivery model is that you receive a license for the software based on a subscription basis. The software is usually cloud-based and you can access it on a variety of platforms. You can choose to pay for as much time as you want, and when you don’t need the software anymore you just stop using it. This is one of the most convenient and professional ways to use software, and it brings in front outstanding solutions at a very good price. 

Some of the main Software as a Service characteristics are that you access the software online, it’s managed by a central location, it’s hosted on a remote server and it will bring in a multitenant architecture. What that means is that everyone shares the same, common infrastructure, but they can choose to customize and modify it the way they want.

How does the Software as a Service platform architecture work?

The core Software as a Service platform will have a single configuration that’s deployed to every customer. The application will be installed on a varied set of machines in order to deliver scalability. Sometimes the Software as a Service system can also have a second version of the application, but that one is usually focused on testing and pre-release functions that are not available in the core ideas at first. 

You can find two different Software as a Service varieties, and each one has its own architecture approach. Vertical SaaS for example answers the needs of a certain industry like healthcare, IT companies, finance, agriculture and so on. Horizontal SaaS on the other hand will focus on a single category within the industry. 

While the Software as a Service platforms are very complex, the way they are deployed is very simple. And since everything is cloud-based most of the time, you won’t have to worry about any updates. You are always getting access to the latest features and versions very quickly. That helps a lot and it helps bring in front a very good experience.
