Software as a Service (SaaS)

What is Software as a Service (SaaS)?

Software as a Service (SaaS) is a cloud computing model that delivers software applications over the internet on a subscription basis. In this model, users can access the software and its features through a web browser without the need for local installation or maintenance. SaaS eliminates the traditional model of purchasing, installing, and maintaining software on individual devices, providing a more cost-effective and scalable solution.

What is typically included with SaaS solutions?

Subscription-based Access

Users pay a recurring subscription fee to access the software, often on a monthly or annual basis.

Centralised Hosting

The software is hosted on the vendor’s servers, and users can access it remotely via the internet.

Automatic Updates

Software updates and maintenance tasks are managed by the service provider, ensuring users always have access to the latest features and security patches.


SaaS solutions are scalable, allowing organizations to adjust the number of subscriptions based on their changing needs.

Multi-Tenancy Options

SaaS applications support multiple users or organisations (tenants) on a shared infrastructure while maintaining data isolation and security.

Common examples of SaaS applications include customer relationship management (CRM) software, office productivity suites, collaboration tools, and enterprise resource planning (ERP) systems. SaaS has become a popular choice for businesses seeking efficient, cost-effective, and easily accessible software solutions without the burden of complex infrastructure management.
