A computer is not just a machine; it has become necessary for growth today. Imagine running an organization without computing resources in the digital age. You can’t even think of competing with others. Even hiring an employee without computer illiteracy is suicidal. 

The next big thing is the accessibility of computing resources. We’re living in a digital transformation era where remote collaboration is crucial for growth. However, traditional computing infrastructure works within a confined space only. For instance, you cannot access your office computer from home unless connected to the internet. On-demand cloud computing can address this challenge. 

The on-demand cloud computing model is now integral to modern IT infrastructure. It is not confined to the physical limitations of machines. It allows users to access their desired computing resources anytime, anywhere. 

This article explains the on-demand cloud computing to beginners addressing their questions and clarifying common misconceptions about this model. 

So, let’s get started. 

What is On-demand Cloud Computing? 

As the name indicates, on-demand cloud computing refers to delivering computing resources over the internet. It enables users to access specific software or functionalities as needed. There is no device, place, or time restriction to cloud resources. 

Let’s understand it with an example. 

You work for a small SaaS startup with less than 100 employees. Your team has a mix of remote, hybrid, and onsite members. As long as you’re in the office, you can access all essential documents stored on your computer. Besides, you can seamlessly use tools like Word, PowerPoint, Excel, etc. 

Now, how can you access your desired resources if you plan to work from home, as many teams did during the pandemic? On-demand cloud computing is the answer. 

This model gives you uninterrupted access to computing resources wherever required. You simply have to connect your PC to the internet, log in to your cloud account, and start doing your work. On-demand fulfills the primary requirement of providing resources as needed. 

Similarly, you can use cloud tools like Zoom, Meet, and Slack to conduct online meetings and discuss projects. Team members can also collaborate and live edit documents with Microsoft Office 365 and Google Workspace. All these are cloud software that makes teamwork easier and more seamless. 

Major Service Categories in Cloud Computing 

On-demand cloud computing has three main categories. Let’s explore them one by one. 

Infrastructure as a Service (IaaS) 

The first category is infrastructure as a service (IaaS). In this mode, third-party cloud providers enable businesses to gain on-demand access to scalable IT infrastructure per their organizational needs.  

Startups and small businesses usually prefer IaaS. They have limited resources and expertise. Hence, instead of spending on expensive IT infrastructure, they collaborate with IaaS providers. This collaboration allows them to access customizable services required to deliver products or services. As their business grows, they expand the scope of IT infrastructure.  

The core benefit of IaaS is that it requires very little capital investment. Besides, employers don’t need to bear the burden of infrastructure management. They can also expand the cloud resources as per their organizational needs. 

Platform as a Service (PaaS) 

Platform as a Service (PaaS) is ideal for companies in the technology sector. This model offers a comprehensive application suite for different organizational operations.  

For instance, a software development company can collaborate with a PaaS provider to build, test, and release custom applications. PaaS solutions are delivered over the internet and don’t need on-premises installation. Hence, users can solely focus on crucial business areas like business development, client sourcing, and operations management. The infrastructure and platform management are taken care of by the PaaS providers. 

Additionally, PaaS solutions bring many features tailor-made to growing users’ needs. By leveraging these tools, companies can reduce their operating costs and work on complicated projects that demand extensive infrastructure. 

Software as a Service (SaaS) 

Software as a Service (SaaS) is the most popular cloud computing model. Both individuals and organizations widely use it for various purposes. SaaS refers to the delivery of customized applications over the internet.  

The most significant benefit of SaaS applications is that you don’t need to install them on your local devices. All you need is just a computer with the internet and login credentials. All features are available online and can be accessed anytime, anywhere, on any device. You can store data, perform your desired functions, and collaborate with your team with SaaS. Besides, your data is secure unless multiple users access your account. 

We use different SaaS applications in our daily lives. Common examples are Zoom, Meet, and Slack. Likewise, Netflix is a good example of online on-demand cloud computing services. You can watch your favorite movies without downloading them on your device whenever you want. 

Top Benefits of On-demand Cloud Computing 

Here’s how on-demand cloud computing benefits businesses and individuals with their exclusive features: 

Cost Efficiency 

Businesses can access their desired resources in on-demand cloud computing without setting up expensive infrastructure, hardware, software, etc. Hence, they can achieve long-term cost savings with significant improvements in their operational efficiency. 

Flexibility to Access 

Since cloud solutions are delivered online, any user connected to the internet can access them whenever needed. There is no restriction of time, device, or place. 


We live in a global village connected via the internet. Cloud computing further empowers this virtual world by ensuring seamless access to the desired IT services. Any individual or business can become a part of globalization with the cloud. 


Data security is a rising concern for most businesses. Cloud providers address this challenge by taking robust cybersecurity measures to thwart potential threats and ensure the safety of confidential data. Hence, you can use any cloud solution without any risk of data breach. 


As businesses grow, their organizational needs also scale with time. On-demand cloud computing is the best way to scale the computing resources instantly while avoiding unnecessary expenses. 

Final Thoughts 

The future of digital transformation is linked with cloud computing. The flexibility this model gives to its users is simply unmatchable. This flexibility and other benefits are the primary reason businesses are swiftly moving to this model. 

Experts predict that on-demand cloud computing will become vital to every industry in the coming years. This transformation has already started. Today, we don’t need to use our device storage to store important documents, files, and data. Cloud storage can store everything securely. Similarly, video streamlining platforms like Netflix and YouTube have eliminated the need for video downloads. 

In the future, we will be able to access our virtual workspaces through cloud solutions. Teams in different parts of the world would work on the same project by sharing cloud resources. This would be the start of a new age, and transformation has already started across many sectors.
