Software as a Service


Software-as-a-Service (SaaS) is a software licensing model in which users pay a monthly fee for access to software that is hosted on external servers rather than on internal servers.

Software-as-a- Users log into the system using a username and password and access the service through a web browser. Instead than having to install the software on their own computer, users can access the program through the Internet.

  • Software-as-a-Service (SaaS) is a software licensing model, which allows access to software a subscription basis using external servers.
  • Allows each user to access programs via the Internet, instead of having to install the software on the user’s computer.
  • It has many business applications, including file sharing, email, calendars, customer retention management, and human resources.
  • SaaS is easy to implement, easy to update and debug, and can be less expensive (or at least have lower up-front costs) since users pay for SaaS as they go instead of purchasing multiple software licenses for multiple computers.
  • Drawbacks to the adoption of SaaS center around data security, speed of delivery, and lack of control.

Understanding Software-as-a-Service (SaaS)

The rise of cloud-based computing correlates with the rise of Software-as-a-Service (SaaS). Cloud computing refers to the technique of providing technology services through the Internet, which often comprise data storage, networking, and servers. Before SaaS, firms who wanted to upgrade their computers’ software had to buy compact disks with the changes and download them onto their computers.

Updating software was a time-consuming task for large enterprises. Over time, organizations began to purchase more licenses rather than additional disks, and software upgrades were available for download via the Internet. However, a copy of the software had to be installed on all of the devices that needed it.

Users do not need to install or update any software when using SaaS. Instead, consumers can access the service by logging in via the Internet via a web browser and connecting to the service provider’s network.

SaaS is an example of endogenous growth theory, which is an economic theory that holds that economic growth can achieve through the development of new technologies and increased production efficiency. Technology firms, financial services firms, and utilities have been among the first to adopt SaaS technology.

History of SaaS

Time-sharing, a concept developed in the late 1950s and early 1960s to make more cost-effective use of expensive processor time, is where SaaS gets its name.

Hardware and computing became less expensive during the next few decades. Using on-premise software, businesses transitioned to individual ownership of personal computers. However, the approach was still inefficient on a broader scale, as firms were burdened by continual software and hardware maintenance of individual computers.

The Internet achieved unprecedented heights in terms of e-commerce transactions in the mid-1990s, which fuelled the emergence of the “online cloud,” which allowed businesses to access software from anywhere.

Salesforce launched its own customer relationship management (CRM) platform in 1999, going all-in on SaaS. Salesforce became the first superstar in the SaaS market thanks to its head start and “no software” credo. It is still one of the largest pure SaaS businesses in the United States.

After Salesforce demonstrated the sustainability of the SaaS business model, organizations of all sizes were eager to adopt it, from small startups to established industry heavyweights like Microsoft, Oracle, and SAP.

SaaS is now widely useful. The SaaS market is estimated to reach $145 billion in 2022, led by pure-play companies such as Adobe, Salesforce, Shopify, and Intuit.

With SaaS, users can access software through a web browser from multiple locations, including outside the office. Remote desktop software can help employees securely access work computers from home or allow technicians to resolve computer issues without having to make an onsite visit.

Advantages and Disadvantages of SaaS


Compared to traditional software licensing methods, SaaS has a number of advantages. There is less demand for the licensing business to invest in new hardware because the program does not reside on its servers.

It is simple to set up, update, and debug, and it can be less expensive (at least in the short term) because customers pay for SaaS as they go rather than purchasing various software licenses for multiple PCs.

SaaS has numerous applications, including:

  • Email services
  • Auditing functions
  • Automating sign-up for products and services
  • Managing documents, including file sharing and document collaboration
  • Shared company calendars, which can schedule events
  • Customer relationship management (CRM) systems, which are essentially a database of client and prospect information. SaaS-based CRMs can hold company contact information, business activity, products purchased as well as track leads.

Enterprise-level services, such as human resources, are often the focus of software that has transitioned to a SaaS model. These jobs are frequently collaborative, requiring staff from many departments to share, edit, and publish material.


The security of data and the speed with which it is delivered are two major drawbacks of SaaS adoption. Companies must ensure that data stored on external servers is secure and unauthorized persons can’t access it.

Slow Internet connections can degrade performance, particularly if the cloud servers are accessible from afar. Internal networks are typically quicker than Internet connections. SaaS solutions suffer from a lack of control and customization due to their distant nature.


Examples of SaaS

Google Docs

One of the simplest real-world examples of SaaS is Google Docs, Google’s free online word processor.

In order to use Google Docs, all you need to do is log in on a web browser for instant access. Google Docs allows you to write, edit, and even collaborate with others wherever you happen to be.

Google Docs launched in October 2012.


It is a simple real-world example of SaaS. Dropbox is a cloud storage service for organizations that allows them to save, share, and collaborate on files and data. Users can, for example, back up and sync images, movies, and other things to the cloud and view them from any device, regardless of location.

It established in the year 2007.

SaaS vs. IaaS vs. PaaS

The market for as-a-service items is quickly expanding. However, they often fall into one of three categories: SaaS, IaaS, or PaaS.

SaaS is a subscription software service that is delivered via the Internet and controlled by a third-party provider. Dropbox, Google Workspace, and Salesforce are all well-known SaaS examples.

Meanwhile, infrastructure-as-a-service (IaaS) provides access to resources like servers, storage, memory, and other services. It enables businesses to buy resources as they are required. Amazon Web Services (AWS), Microsoft Azure, and Rackspace are some examples of IaaS.

Finally, platform-as-a-service (PaaS) offers a web-based software development platform. It helps developers to concentrate on software development rather than worrying about storage and infrastructure.
