What is SaaS? A Quick Intro

4 Mins read

Software deployment has shifted from making regular installations and configurations on hardware to the utilisation of virtual computers through cloud computing. SaaS has made such a shift possible.

This model of software delivery has been beneficial to its providers. According to BMC, SaaS is expected to bring in nearly $105 billion this year, and close to $141 billion in 2022.

What is SaaS?

SaaS, or Software as a Service, is a software delivery model in which software is made available via the web or through an API, and can be accessed by users on a subscription basis.

In simpler terms, it involves the deployment of software over the internet to users/businesses who pay on a subscription basis, either monthly, annually or custom intervals.

Since SaaS can be accessed via the internet, it allows users to make use of it on any internet-enabled device. It can also be integrated with other tools in an organisation through an Application Programming Interface (API).

Benefits of SaaS

SaaS offers a tonne of benefits to not just users, but providers. This section lists out 7 top benefits.

a. Ease of Use / Implementation

Unlike native applications which require you to have specialised knowledge on given hardware, and might incur extra costs to implement, SaaS products can be used easily as they can be implemented with little or no need for configurations.

This is because they’re installed and configured in the cloud. Also, SaaS products offer easy-to-follow guides to help customers quickly get started.

b. Ease of Access

A popular benefit of using a SaaS product is how easy it is to access. Since the software is hosted on the cloud, users can gain access to it via the internet.

This eliminates the worry of the software’s compatibility with your Operating System (OS), be it macOS, Windows, or Linux. Users can make use of the software not only on desktop computers but also on mobile devices, as such applications are designed to be mobile-friendly/responsive.

c. Upgrades

Since SaaS products are centrally hosted, providers can push updates to the software and make it available as soon as possible to all customers for use without affecting their activities.

On the side of the SaaS provider, the efforts made to implement such updates are lower than those required to make it possible for traditional software.

Upgrading traditional software might require purchasing a newer package to install and might also require you to pay extra fees to access support to make the installation possible.

d. Reach

Businesses of any scale can access SaaS products, which in turn, improves their services and opportunities. SaaS enables providers to supply software to the majority of the market, eliminating the limitations of a targeted segment.

This results in broader market reach, making it accessible to not just large-scale enterprises, but start-ups that wouldn’t have had access due to high licensing costs. This brings us to the next benefit, affordable pricing.

e. Affordable Pricing

From the definition of SaaS, we got to know that it is offered on a subscription-based model. These subscriptions are offered either on a monthly, annual, or custom interval. Coupled with the fact that it’s hosted on the cloud, it eliminates the extra costs incurred for hardware installation and maintenance, a problem usually encountered by organisations using traditional software.

On the side of the SaaS provider, they wouldn’t be too concerned with piracy, as customers can only gain access to their product after making payment. This can’t be said for providers of traditional software as their products easily fall victim to piracy.

f. Analytics

With SaaS, everything runs on a centralised platform. This makes it easy for customers to gather data and make accurate analysis. SaaS providers usually offer tools to their users to provide valuable insights, which in turn, helps improve their workflow and efficiency.

g. Scalability

In organisations, the demand for IT resources change, and this is easily adjustable for SaaS customers as they wouldn’t need to purchase additional hardware or abandon them when they aren’t in use.

SaaS providers offer easily customisable options for their users to add or drop resources as their demands change, which in turn, has an effect on their subscription.
