Knowing SaaS to the Core & a Complete Guide to Best SaaS App Development Methods


Introduction to SaaS

SaaS is Software as a Service. As the name suggests, SaaS allows software providers the ability to provide their application’s services to the users without the users requiring the need to install that particular application in their devices. All this is done via the internet, on the internet. Let’s understand this using an example:

Have you heard of or used Zoom or Slack?

Even if your answer is no, you can go check right now – these are the platforms for business communication via audiovisual calls or messaging. When you search them, you can see that none of these applications require installation, meaning you can use them directly on the internet.

Now, this is possible because they are SaaS applications. These applications are hosted on their respective servers, and you can use them whenever you want without installing them on your devices – all you need is a stable internet connection.


Types of SaaS Apps

There can be various types of SaaS apps – precisely, it can be whatever you want it to be; however, usage of SaaS apps can be most sought in the below sectors.

Differences Between SaaS Applications & other Web Applications

SaaS applications & web applications both use servers to be hosted, and both can be accessed via web browsers by the users – then what’s the difference between them?
There are still differences between them – please look at the points below to get clarity between the duo.


Deployment Model

SaaS Applications

SaaS is a software delivery model where the application is centrally hosted and provided to users on the internet. Users typically access SaaS applications through a web browser – eliminating the need for individual installations on local devices.

Web Applications

As SaaS, web applications refer to any software application accessed through a web browser. Hosted on a central server, they might require individual installations on user devices.


Licensing & Accessibility

SaaS Applications

SaaS applications usually follow a subscription-based licensing model. Accessibility is typically universal through web browsers, and updates are managed centrally by the service provider to ensure all users have the latest version.

Web Applications

Web applications may have various licensing models, and accessibility might depend on individual user licenses or installations. Unlike SaaS, web app users often need to manage updates themselves.


Customization & Scalability

SaaS Applications

SaaS applications are designed with multi-tenancy and scalability in mind. They often provide customization options to allow users to customize the application according to their needs without sacrificing the advantages of a centralized architecture.

Web Applications

On the other hand, with web apps, customization & scalability depend on the design and architecture choices made during development. Some web applications may allow customization, but scalability may require additional efforts.


Maintenance & Upgrades

SaaS Applications

Maintenance & upgrades are handled centrally by the service provider. Users have access to the latest features and security updates without individual intervention.

Web Applications

Users typically handle maintenance tasks, such as updates & patches, on their respective devices. This can lead to fragmentation and potential compatibility issues.


Why SaaS Development?

When the talk is about SaaS apps, the question should not be why SaaS; instead, it should be why not SaaS.

Since we have already gone through the SaaS app benefits, it’s better to show you the scale on which SaaS applications are being used and flourishing.

This year, the SaaS app market is expected to cross the $215 billion mark. Over 86% of companies use SaaS software in their systems, and more to join this figure sooner.
