What is a SaaS Application?

If we compare a SaaS application with our life, it’s like the water supply connection in our homes. All the consumers access the same water supply. Whenever they need, they can open the tap and get access to water through the vast scale of supply channels built by municipal corporations.

Here, the consumers need not worry about water leakage, quality or maintenance of the services. The municipal corporation manages all this. So, while creating parallels between these two services, let us understand the SaaS model.

It is a kind of centralised SaaS product-based subscription model with cloud-computing architecture for online services like email, office tools, photo editors, and other specialist applications, delivering an application over the internet, in the form of a service. Over here, the SaaS Businesses host the cloud service servers, the foundational hardware architecture, app data, and cybersecurity infra; and manage the access, security, availability, performance, and maintenance of the application as well.

​​Hence, the clients get cloud-based applications from a Cloud Computing Solutions Provider on rent, at minimal upfront costs, where you pay-as-you-use, and their users access it over the internet.

To better understand the topic, suppose we have a photo to edit. You need not have your personal laptop, PC or mobile phone. If you have access to the internet on a screen device, you can edit it from anywhere, using any of the cloud applications available online. One of the best features is, as the application is accessed online whenever and wherever the user wants, there are no software maintenance needs from the user side.

On top of that, it is easy to customise the applications as per the business needs in their various processes, without affecting the core software solutions infrastructure of the SaaS Application.

Some Other Types of Cloud Computing Solutions for Business IT Systems

A few other cloud computing services available in business solutions are:

  • PaaS (Platform as a Service): Here, the platform on which the client will develop, manage or run its own customised applications with the help of multiple developers, is offered as a service through the internet. Example: AWS, Google app engine.

  • IaaS (Infrastructure as a Service): Here, the whole infrastructure of network, servers, and operating systems, needed to build a solutions system is offered as a service to the businesses who need only the hardware technology for cloud computing from the IT-Solutions providers. Example: Google Compute Engine, Microsoft Azure
  • XaaS (Everything as a Service): This is a whole package of services which includes end-to-end Cloud-Computing Solutions, i.e. SaaS, PaaS, and IaaS services to the clients. Example: Microsoft Azure.

Benefits of SaaS Application

Following are some of the benefits of SaaS Applications: 

  •  Negligible Setup and Infra Costs on Balance Sheet.
  • Accessibility
  • Vast Scalability
  • Frequent Debugging and SaaS Software Updates
  • Enhanced Cybersecurity:
  • The flexibility of Use
  • Accessibility: 

Let us further understand these features with more clarity:

1. Negligible Setup and Infra Costs on the Balance Sheet

SaaS-based businesses provide nil installation, app updates, or hardware and software maintenance charges for sophisticated applications like project management, CRM, employee tracking, etc. Thus, there is a negligible maintenance cost for these specialised apps on the balance sheet.

2. Accessibility

As the internet is accessible in almost all remote locations, you can access the SaaS solutions via laptop, mobile, PC, etc.

3. Vast Scalability

The SaaS platforms are adaptive as per the needs of any number of users, any amount of cloud data, and various functions as per the customisation by the businesses.

4. Frequent Debugging and SaaS Software Updates

The updates and debugging of SaaS applications are very frequent from the user feedback about their needs. This saves time for the company’s IT department for business-core activities.

5. Enhanced Cybersecurity

The vast amount of users’ big data access is protected from the highest level of security standards. The security level is the same for all users.

6. Flexibility of Use

The pay-as-per-use system saves money for users and promotes its usage. No special software are required to be purchased by the clients of these companies.

7. Accessibility

As it is a cloud computing-based application, users can access the SaaS platforms even from remote locations with any internet-connected device without losing any data if the user’s device fails.

It will help create an outline of the SaaS product by assembling data and brainstorming the platform features, giving particular cost estimates, preparing maintenance plans, etc.

3. Design the Software 

Here, research on UX and UI is performed. Proper interfaces are tested using big data on the target audience’s behaviour patterns, the gadget platforms they use, and so on.

4. Create Software Package Architecture

A cloud-based software architecture designing system is used at this stage. The software architecture system must possess the features of adaptability of the cloud databases and programming language, scalability of the system, security of big data, and ambient pricing rates.

5. Testing the Product

Quality assurance is done using the Agile Approach on the front-end and back-end of the software, its platforms, its functions, and many more.

6. User Feedback and Routine Maintenance

Here, studying user input, further improvements, and add-on features are performed.
