What Is IaaS and what does it stand for.

As soon as you read the title of this article, this question must have come to mind of most of you. So in today's article we are going to tell you about IaaS itself, and also learn more about it. So let's begin.

What is IaaS? First we come to this question. This is a cloud computing related term. You should also read our first article on cloud computing for better understanding. We also talked about it in that article. Let's come to the second question, i.e. What does IaaS stand for? Well, short answer to this is IaaS stands for Infrastructure as a Service. This means, using a computer infrastructure as a service.

IaaS is a type of cloud in which cloud service providers deliver services like servers, storage, and networking to you through a private interface. These services are provided over the internet and on pay-as-you-go basis. Pay-as-you-go, as we know, means that we only pay for the service we use.

With IaaS, users can scale up or down computing resources as needed. This way they can avoid having to "own" different devices unnecessarily, and the resulting cost increases.

Where Does IaaS Helps The Most?

IaaS is very useful in the applications where the workload is very high. With IaaS model, you can have a better control on your cloud sources. Even the models like Platform as a Service, Software as a Service and Serverless, can't offer such control.

Since 2010, IaaS has become a standard for computing. And since then, users declare it the most popular computing model.

What Is IaaS? What Are The Building Blocks Of This Platform?

IaaS is a collection of resources, both physical and virtual, that provide customers with all the basic components needed to deploy cloud-based applications. Now let's talk about the components i.e. building blocks of IaaS.


It provides the infrastructure for delivering services and resources over the Internet. It enables enterprises to rapidly scale their computing resources as needed, without having to invest in and maintain physical infrastructure.

Hence, computing is an important component of IaaS model. It lays foundation to offer other services as Platform as a Service and Software as a Service.

Cloud computing is often accompanied by supporting services such as auto-scaling and load balancing, which provide the high availability, scaling, and performance qualities that make the cloud more attractive.

Physical Data Centers

IaaS services providers oversee enormous data centers located around the world that contain physical computers, servers, storage, security, and network devices. Thus end users will be able to access these physical devices with the help of virtual infrastructure.

As end users, we don't usually interact directly with physical infrastructure in IaaS model, but we access it as a service.


In cloud networking, traditional networking-related hardware such as routers, switches, etc. are provided to users through certain APIs with the help of a program.

Data Storage

There are three types of storage in cloud storage which are file storage, block storage and object storage. Block and file storage are used in traditional storage the most. But they struggle to cater the scalability and performance features of cloud.

Being highly distributed, object storage has become the most prominent form of cloud storage. It uses commodity hardware and helps access data at the API end points. For end users like us, storage is unlimited in object storage services.

Applications Of IaaS Model

Cloud's flexibility and ease of use make IaaS resources highly scalable and robust. We've also seen uses of cloud computing before, many of which will also be included in the IaaS model. So after we have talked about what is IaaS, let's talk about its uses.

Testing And Development

With IaaS, your team is able to quickly build and disassemble testing and development environments. This way you as a company can bring your new apps to market faster.

With the IaaS model, testers and developers can scale up or scale down their testing and development environments very quickly and efficiently at low cost.

Migration Of Applications On Cloud

IaaS model is the quickest and most effective way of migrating an app on cloud. In this model, you can improve scaling capability and application performance without changing the existing architecture.

Data Storage, Recover And Backup

Your company can avoid the cost of storing data and the complexity of managing storage. This usually requires hiring qualified personnel to manage data and meet legal requirements.

IaaS storage helps deal with fluctuating demand and ever-increasing storage requirements. It can also simplify the planning and management of backup and recovery systems.

Better Performing Computing

Supercomputers, computer grids, and computer clusters solve critical problems involving millions of highly complex calculations. The common features of all these computers are available to you in the cloud with just a few clicks. Some examples of this are protein folding, earthquake simulations, weather and climate predictions, financial modeling and product design assessment.

What Is IaaS?: Usage In Web Apps

IaaS provides all the infrastructure needed to run online apps, including storage, web and application servers, and networking devices. Your company can quickly build web apps on IaaS resources and scale up or down the infrastructure required by the app.

Benefits Of IaaS Model

After we knew what is IaaS, we saw some of its applications. Now, below we are going to present some of the benefits of IaaS model, which are more or less similar to that of cloud computing:

It Reduces Cost

IaaS reduces the cost of setting up and maintaining a physical data center, making it a low-cost alternative to the cloud. Pay-as-you-go subscription models are the standard method among IaaS service providers, allowing your IT team to focus on your core business while saving money on hardware and maintenance.

There are other pricing options and optimization techniques as well, which can lower your costs.

Scalability And Performance

Being scalable is the biggest asset of IaaS model. You can scale applications internationally and accommodate increased resource demand with IaaS. In this way, you can launch your app internationally and can improve its performance.

Better Stability, Dependability And Supportability

IaaS eliminates the need to maintain and upgrade software and hardware and deal with equipment issues. With the right contract in place, your service provider ensures that your infrastructure is reliable and compliant with Service Level Agreements.

Business Continuity And Data Recovery In Case Of Any Disaster

High availability, business continuity, and disaster recovery can be a costly process as it requires significant investment in technology and manpower.

On the other hand, if right service level agreements are in place, IaaS can lower this cost as well. IaaS can recover more quickly and efficiently during a crisis or outage than maintaining your physical server.


If you enter into a better service agreement with a cloud service provider, it can further improve the security of your infrastructure.

What Is IaaS?: Conclusion

Finally, the IaaS computing model has revolutionized the way organizations approach their IT infrastructure. With IaaS, organizations can focus on their core business processes while leaving infrastructure management and maintenance to service providers.

This shift in IT infrastructure management has made it possible for organizations of all sizes to harness the benefits of cloud computing, making IaaS a critical component of modern IT architectures.۔
