What is SaaS and How It Works? – 2022 Guide

Almost all the users have probably encountered the SaaS concept at least once. So, if you still do not know what is SaaS and how it works, then it is high time to keep up reading this article. In this 2022 guide, you will reveal all the advantages and characteristics of SaaS products.

What Is SaaS?


If simply described, SaaS stands for Software as a Service and is one of the cloud computing categories. It is a way of providing applications and software through the Internet presenting it as a service. For example, Door3 is a company that provides financial software development services.This eases the user experience. As instead of passing through the installations or software maintenance processes you are able to access them through the Internet. Due to this feature, SaaS products are sometimes called web-based, on-demand, as well as hosted software. You obtain all the valuable and crucial components such as security, performance, and availability from the provider.

So, this means that you need only a simple Internet connection to access the SaaS product and make anything with it.

How Does SaaS Model Work?


SaaS products have an interesting working model. We may divide them into characteristics mentioned below:

  1. Multi-Tenant Architecture: All the product users share the same SaaS infrastructure and codebase. This helps them a lot. Because they get rid of spending hours maintaining obsolete code versions. Furthermore, using low-code tools can make SaaS development more efficient. These tools help by allowing faster changes and making the process of writing code by hand less complicated.
  2. Simple Customization: This enables the users to customize the SaaS applications without harming the main infrastructure. This means that the customizations are specific for each of the companies or users. This is preserved by upgrades. Correspondingly, SaaS product owners can make upgrades more frequently. Meanwhile, this will cause fewer client risks and lower costs for adoption.
  3. Improved Access: Any of the networked devices will have improved access to data.

What Are The Other Cloud Computing Categories?

As you may guess SaaS is not the only cloud computing category. There you will encounter also Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). The main feature connecting these three main cloud service models is that all of them include cloud providers delivering their hosted data center resources to clients through the Internet. Below you will meet the differences between these three concepts:

Those who use SaaS products are not obliged to download this or that software or application, as well as they do not need to manage already existing IT infrastructures. All of those processes are managed and maintained by the vendors.

Unlike SaaS products, IaaS users are those who want to just outsource their data center or other computer resources to the provider. Surely, IaaS cloud providers host servers, storage, virtual resources, and network hardware. Yet, the customers have to manage the data use, operating systems, etc. on their own.

And finally, PaaS enables the in-house developers to obtain resource frameworks. In other words, they get a hosted platform to make customized applications.

Advantages of SaaS


So, coming to the SaaS advantages it is worth mentioning that these products decrease the expenses related to the acquisition of hardware, and maintenance. Besides, you are not required to spend your resources on software installation, licensing, as well as its support. So, summing up, below you will meet the advantages of SaaS products:

  • Payment Flexibility – in the case of SaaS products you do not have to purchase any software, install it, or seek premium support. Instead, you pay for the subscription. This mode of payment makes the business budgeting process even easier. In addition, when the users do not want to continue the subscription they can stop it anytime they wish by simply not renewing the license.
  • Vertical scalability – this is provided by the cloud services such as SaaS. This enables the customers to use as many services as they wish according to their purposes or demands.
  • Constant updates – on this condition, SaaS providers and owners do automatic updates to give their customers the best user experience. So, they are not obliged to buy new software every time.
  • Easy accessibility – By using SaaS products the users get fast and smooth accessibility to the product on almost all devices that are switched to the Internet.
  • Customization ready – The majority of SaaS apps are customizable. So, they can be integrated into other applications.

Disadvantages of SaaS


Along with all the perfect features in the Software as a service application, they have some disadvantages, too. So, at this point, we will meet the disadvantages and risks related to SaaS products.

  • Issues that are not under the user’s control – You as a user may encounter these issues when the provider makes unwanted changes. This can somehow disturb the customer’s usage of the product. So, the user must understand the Service Level Agreement.
  • Users do not have control over versioning – this is also a serious reason. Because the adopted version of the provider will be passed through all the app users. And they do not have the power to change it even if they do not want to use exactly that version.
  • Customers may encounter some difficulties while switching vendors. As every time they must migrate huge data.
  • Security is the last disadvantage of SaaS products. Sometimes it concerns the users because of security monitoring, data residency requirements fulfillment, data privacy, and lack of contact between technical and security experts during the purchasing processes.

When It is Beneficial To Use SaaS Products?

Under some circumstances, it is effective to use SaaS products. You will find those cases listed below:

  • Small, low-budget, and startup companies and businesses that aim to open e-commerce platforms quickly. These usually do not have time or budget for solving server or software issues.
  • Projects that are not so long-lasting and only need a short-time and affordable cooperation.
  • Apps that require web and mobile access. Besides, there are some others that are not utilized so frequently.
