Basic Things to Know About Software as a Service (SaaS)

Last Updated on April 12, 2023

Software as a Service (SaaS)

Software as a Service (SaaS), usually referred to as cloud-based software, is now widely used. And with good cause. Web-based business apps are paid for on an hourly basis rather than all at once and don’t require difficult installations or binding contracts. The systems are typically more adaptable and cost-effective due to this.

What is SaaS?

Software as a Service (SaaS) is a relatively new method of distributing software that allows users to access programmes online without the need for special installation or physical discs. SaaS products are maintained and automatically updated by a provider who also centrally hosts them. Customers use them and have access to them through mobile and online browsers. Software as a Service has unquestionably transformed the way software is delivered.

Introducing a new application to an organisation used to be a burden. Before staff members could begin using a new tool efficiently, it could easily take weeks, if not longer, due to the drawn-out sales process, difficult on-site installation, custom creation, and training. This can happen with SaaS in a few days or less.

As a result, Software as a service is quickly replacing other delivery models for essential business applications. In fact, established on-premises software suppliers are now developing SaaS products, and they frequently broaden their product portfolio by purchasing SaaS firms. A few instances are Oracle buying Opower for $532 million, Microsoft Teams, Amazon Chime, and Microsoft Teams. Unlike IaaS and PaaS, SaaS products are frequently marketed to both B2B and B2C users.

How Does Software as a Service Work?

Software as a service utilises the cloud delivery model to function. An ISV may hire a cloud provider to host the programme in the provider’s data centre, or a software provider may host the application and accompanying data using its own servers, databases, networking, and computing capabilities. Any device with a network connection will be able to access the programme. Web browsers are often used to access SaaS apps.

Because of this, businesses that use SaaS apps are not required to set up and maintain the software. Users can access the programme by just paying a membership charge, which is an already-made solution.

Software as a service is closely related to the on-demand computing and application service provider (ASP) software delivery models, where the provider hosts the client’s software and sends it via the internet to authorised end users.

In the software-on-demand SaaS model, a single copy of an application that the provider developed especially for SaaS distribution is made available to consumers via a network. All clients share the same source code for the application, and as new features or functionalities are made available, they are distributed to all users. The customer’s data for each model may be kept locally, in the cloud, or both locally and in the cloud depending on the service-level agreement (SLA).

Using application programming interfaces, businesses can combine SaaS apps with other software (APIs). A company may, for instance, create its own software tools and interface them with the SaaS service using the APIs of the SaaS provider.

SaaS Characteristics

A suitable analogy for the SaaS model is a bank, which preserves each customer’s privacy while offering a service that is dependable and secure—on a large scale. Customers of a bank can utilise the same financial technologies and systems without being concerned about unauthorised access to their personal data.

Multitenant Architecture

a multitenant architecture where all users and apps share a single, centrally maintained infrastructure and code base. SaaS providers are able to innovate more quickly and save important development time because all of their clients use the same infrastructure and code base. Previously, vendors would have had to maintain numerous versions of obsolete code.

Easy Customisation

Allowing users to quickly alter applications to meet their particular business processes without having an impact on shared infrastructure These customizations are exclusive to each business or user and are always maintained across upgrades because of the way SaaS is built. As a result, SaaS providers can release updates more frequently, with substantially lower adoption costs and reduced client risk.

SaaS Harnesses the Consumer Web

The web interface of common SaaS apps will be familiar to anyone who is familiar with or My Yahoo! The SaaS model allows for easy customization, making the weeks or months it takes to upgrade conventional company software appear hopelessly antiquated.

Better Access

Improved access to data from any networked device while making it simpler to control access rights, keep track of data usage, and guarantee that everyone is viewing the same information at once.

SaaS Trends

For the purpose of creating new SaaS applications, organisations are currently creating SaaS integration platforms (or SIPs). When Software as a service goes beyond standalone software capabilities and turns into a platform for mission-critical applications, it is known as the “third wave” in software adoption, according to consulting firm Saugatuck Technology.

SaaS is one of many cloud computing remedies for enterprise IT problems. Additional “as-a-Service” choices include:

  • Infrastructure as a Service (IaaS) – the provider hosts hardware, software, storage and other infrastructure components
  • Platform as a Service (PaaS)
  • Everything as a service (XaaS) – which is essentially all the “aaS” tools neatly packaged together.

These services typically have a per-seat, per-month fee based on usage, meaning that a business only has to pay for what they actually use, which lowers up-front costs.

SaaS Vendors and Examples

There are many different software suppliers and products available in the SaaS industry. Players in the market range from modest, one-product manufacturers to massive cloud providers like AWS and Google.

SaaS products come in a variety of forms, from tools for IT business analytics to streaming video services. Basic company functions including email, sales management, customer relationship management (CRM), financial management, human resource management (HRM), billing, and collaboration are all covered by SaaS apps. Vertical SaaS products are enterprise SaaS applications designed for certain industries, like insurance or healthcare.

SaaS products may be primarily marketed to B2B, B2C markets or both. Examples of popular SaaS products include:

  • Salesforce
  • Google Workspace apps
  • Microsoft 365
  • HubSpot
  • Trello
  • Netflix
  • Zoom
  • Slack
  • Adobe Creative Cloud
  • Shopify
  • Mailchimp

Advantages of SaaS Technology

SaaS software develops more quickly than on-premise software, as do its development cycles. Software as a service offers small businesses the chance to upend established markets while enjoying favourable SaaS pricing structures as a comparable cloud service.

SaaS solutions are beneficial in many commercial settings since they are simple to adopt and may be self-provisioned for user-friendly apps that are accessible on public clouds. However, integrating cloud SaaS systems needs vendor training and hands-off configuration.

Size of business

Smaller organisations will primarily choose the best SaaS solution, especially when a relatively straightforward process is involved. While SaaS solutions can be effective for businesses, some of them fall short in handling the complicated needs of bigger organisations without the addition of setup.


Software as a service provides simple flexibility to meet any company’s changing business requirements. For instance, you can easily update your plan with more licences as your business expands and your capacity and user base develop.


Software as a service removes the need for hardware from the company’s business plan. The database, code, and other server software components are hosted and maintained by the provider. Hardware installation and purchase are not necessary because SaaS application developers do not have to install or run their applications on the business’s servers. As long as it doesn’t employ PaaS and IaaS, there is a substantial demand for equipment on the provider’s SaaS side.


In order to prevent falling out, SaaS suppliers need to be vigilant to maintain their platforms updated. You may instantly upgrade the software to the most recent version thanks to web-based software. As a result, you won’t need to spend money annually updating the software for every employee to run your business effectively.
