What is SaaS Software?

SaaS (software as a service) is a cloud delivery model in which software applications are made available to customers on a subscription basis. Users access SaaS apps on their devices using a web browser such as Google Chrome, Microsoft Edge, or Firefox, rather than installing or maintaining software apps locally.

SaaS software includes customer relationship management (CRM), enterprise resource planning (ERP), email marketing, project management, and collaboration tools. Before creating SaaS applications, you must know how the SaaS software functions. In the next section, let’s understand the working nature of SaaS applications.

How Does SaaS Software Work?

Here’s a basic breakdown of how SaaS works:

  • Software is hosted and managed by the provider on their servers/cloud infrastructure
  • Users access the software via the internet (web browser or thin client)
  • Users pay a subscription fee (monthly/annually) instead of purchasing the software outright
  • The software can be customized and scaled based on user requirements
  • SaaS provider handles software updates, maintenance, and security
  • Finally, data storage and security (backups, disaster recovery) managed by the SaaS provider

What are the Characteristics of SaaS Software?

How do you ensure that the software or an application is built on a SaaS model? Here are the key characteristics of a SaaS solution.

  1. Multi-tenancy Architecture

    SaaS applications are created to service numerous clients using a single instance of the program. The multi-tenancy design enables optimal resource use and scalability, assuring cost-effectiveness.

  2. Subscription Model

    SaaS programs operate on a subscription basis, with customers paying recurring payments monthly or annually to access the product. In comparison to traditional software licensing, a subscription-based approach offers greater flexibility and cost. For example, subscription models like pay-as-you-go or custom plans offered by vendors.

  3. Cloud Infrastructure

    SaaS applications are hosted on cloud infrastructure provided by either the SaaS vendor or a third-party cloud service provider. The cloud infrastructure allows on-demand access, regular updates, and enhanced reliability.

  4. Web-based

    SaaS apps are delivered over the internet and accessed via a web browser on the client’s device. Additionally, SaaS-based software eliminates the requirement for software installation and maintenance on the user’s end.
