Analysis Of Software As A Service Model

Software as a service (SaaS) is a software delivery model where a third-party provider hosts apps and avails them to clients over the Internet. Based on current trends, it is projected that more than 80% of apps will be delivered via SaaS by 2022. It’s generally regarded as a category of cloud computing.

With the SaaS model, clients are provided with specific access to a copy of the app the provider has created for Software as a Service distribution. Many organizations have combined SaaS applications with other software applications using programming interfaces to achieve success. General SaaS applications for vital firms’ technologies include email, sales management, finances and human resource management.

Why Bother?

  • SaaS eliminates the need for companies to run applications on their computers thus reducing expenses related to hardware acquisition, software licensing and installation. 

  • It offers flexible payment options; SaaS provides income for users who purchase either a license or a subscription.

  • SaaS offers high scalability usage, by offering customers choice in accessing more services or features on-demand.

  • SaaS is cost-effective and facilitates automatic delivery of software updates. 

  • Users can access SaaS applications from anywhere there’s Internet  

SaaS (Software-as-a-Service) Development 

The development process includes several different activities. SaaS software development projects typically place emphasis on design, integration and scaleability. SaaS testing has to cover all these activities and more for it to triumph. 

Key Considerations

  • Multi-tenancy Vs single tenancy SaaS architecture: The largest benefit of multi-tenancy is cost-effectiveness since all expenses like server fees and updates are shared by multiple tenants.

  • Increased Security: The confidential data for each tenant is isolated and accessible only by a unique keyword or code for each user; data may be stored on the same server or on different servers. 

  • Performance Accessibility: SaaS development provides the flexibility to manage features that can be executed for certain packages or licenses.

Development Process

Pre-development Stage 

This stage involves analyzing requirements to estimate time and budget, researching and thinking over the best technology stack as well as the architecture.

Unit testing

These are the methods used to ensure that applications built using the software as a service model of development function as designed.


Creating a SaaS application design involves taking a look at your application feature scope, considering customer acquisition costs and comparing it to customer lifetime value.


Debugging is a multistep process that involves identifying a problem and then removing errors from computer hardware or software.


SaaS data integration allows users to distribute applications to those within their organization safely, securely and without configuration; allowing them to easily share applications.
