What is SaaS?

SaaS, the short form for software as a service, is an internet-based software delivery model where users can access and software services via a browser. The software is centrally hosted in the service provider's data center and can be accessed in a subscription framework. With SaaS, customers don't have to install the software on their devices or update them from time to time - the SaaS provider is responsible for the smooth running of the application on devices.

SaaS applications can be in various forms - they can be personal or organizational in nature. Some examples of SaaS are email/messaging services, calendaring, office software, enterprise resource planning (ERP), human resources management (HRM), geographic information systems (GIS), virtualization, and CAD software. SaaS helps organizations to start functioning smoothly without the burden of setting up all software infrastructure from scratch.

Here's a look at some of the services offered within the SaaS umbrella.

  • Physical data center infrastructure
  • Networking and security firewalls
  • Servers and storage
  • Operating systems
  • Development tools
  • Data management and analytics
  • Hosted applications

Major Advantages

Accessibility: SaaS applications are easily accessible via web browsers, regardless of the operating system being used. Hence, users don't have to worry about application compatibility or system hardware requirements.

Subscription model: The pay-as-you-go subscription model of SaaS applications means that the service scales according to usage. It also allows users to save on infrastructure and licensing costs.

Free software services: Users don't have to download or install the software and use it comparatively free of cost. Furthermore, updates and upgrades of the software are carried out by the SaaS provider.

Availability across devices: Users can access the software from devices of their choice - applications are available in desktop, mobile, or tablet formats.

Flexibility for teams: Since the data on the application is hosted on the cloud, users can even access it simultaneously across devices. This benefit works great for collaboration among team members.

Security: Users don't have to worry about establishing security protocols/firewalls for applications as the service provider is responsible for the same.

Data and Analytics: The centralized data storage of the collected data means that processing and analytics can also be done easily by the provider. Enterprises can request the analytics from the SaaS provider as needed and gain insights from the results.
