IaaS (Infrastructure as a Service)

IaaS stands for Infrastructure as a Service. In simple terms, it’s a cloud computing service that provides virtualized computing infrastructure over the internet. Instead of owning and maintaining physical servers, businesses can rent virtual servers, storage, and networking resources on a pay-as-you-go basis. This allows for greater flexibility and scalability, as users can easily scale their infrastructure up or down based on their needs without the burden of managing hardware.

Characteristics Of IaaS

In the infrastructure-as-a-service (IaaS) model, all other technology stack components are established and maintained by the subscriber, who only leases the hardware infrastructure (networking, servers, storage, data center space, and virtualization services).

1. Resources-as-a-service

The cloud service model is based on the concept of resources-as-a-service. As an alternative to spending money on the up-front equipment costs associated with creating and managing a server room or data center, the cloud service model allows organizations to access and implement IT infrastructure with a subscription-based payment model that’s more affordable.

2. Pay-as-you-go pricing model

IaaS services are provided on an on-demand basis and billed on a pay-as-you-go basis, making them a cost-efficient option for smaller organizations that can only afford to pay for the computing resources they use. An IaaS provider might bill according to the number of virtualization instances created or based on the quantity of data stored.

3. Scalable services

The ability to quickly and easily scale service is one of the major benefits of the IaaS model. Cloud service providers maintain data centers with large volumes of servers and data storage available, which can be apportioned to a customer upon request. 

This significantly cheapens and simplifies the process of scaling up IT infrastructure for subscribers to IaaS services compared to organizations that deploy IT infrastructure in an on premise data center.

4. Automated administrative tasks

IT organizations that manage data centers and hardware infrastructure in the on premise model are responsible for routine updates, patches, and maintenance activities that can affect the availability of hardware resources and the software applications that depend on them. In contrast, IaaS service providers handle upgrades and maintenance to their servers without compromising infrastructure availability for customers.

5. Platform virtualization

Platform virtualization refers to creating a virtual machine that acts as a logical abstraction of a hardware platform. The main purpose of virtualization is to divide the resources of a mainframe computer between different functions and applications and to segment those environments from each other for operational or testing purposes. Platform virtualization enables IaaS subscribers to deploy virtualized computing instances as needed to support software development and other tasks.


Infrastructure as a Service (IaaS) plays a crucial role in modernizing and simplifying the way businesses manage their IT infrastructure. It allows organizations to rent virtualized computing resources, such as servers, storage, and networking, on a flexible and scalable basis. With IaaS, businesses can avoid the upfront costs and complexities of owning and maintaining physical hardware. This cloud computing model enables them to scale their infrastructure up or down based on their needs, pay only for the resources they use, and benefit from the service provider’s management of underlying hardware.


Infrastructure as a Service (IaaS) is vital for businesses seeking flexibility, scalability, and cost-efficiency in managing their IT infrastructure. By allowing organizations to rent virtualized computing resources instead of investing in and maintaining physical hardware, IaaS minimizes upfront costs and simplifies the management of IT systems. This cloud computing model enables businesses to easily scale their infrastructure based on demand, paying only for the resources utilized. The importance of IaaS lies in its ability to provide a dynamic and responsive foundation for digital operations, allowing companies to focus on their core activities, innovate more rapidly, and adapt quickly to changing business requirements.
