Benefits of IaaS

What is IaaS? What are the benefits of IaaS?

Firstly, infrastructure as a service, or IaaS, is a cloud-based service that provides you with virtualized computing resources over the internet. IaaS is one of the three main types of computing services, alongside SaaS and PaaS.

To learn about all three computing services, check out our free guide here.

IaaS delivers cloud computing infrastructure, including servers, networks, operating systems, and storage, through virtualization technology.

Organizations are typically provided with a dashboard or an API, which in turn gives them total control over the infrastructure.

The objective of IaaS is to allow organizations the same capabilities and technology of an on-premise data center without having to purchase the hardware outright or manage it all.

Furthermore, cloud providers deliver IaaS to consumers on-demand, over the internet, and on a pay-as-you-go basis.

Here is a list of some of the top advantages and benefits of IaaS.

Top advantages of IaaS


IaaS quickly scales up and down on-demand, letting you pay only for what you use. IaaS is the most flexible cloud computing model. Organizations can change out specific hardware and software easily as their needs evolve. For instance, as soon as you decide to launch a new product or application, the necessary computing infrastructure can be ready within minutes or hours. In contrast to traditional internal set up of infrastructure, which could take weeks and sometimes months to set up.


IaaS can be an economic option for start-ups or enterprises testing new ideas because it eliminates the upfront expense of buying hardware outright and managing an on-premise data center. Furthermore, resources can be purchased as needed, letting you pay for only what you use. For instance, IaaS is an effective model for experimental applications. Organizations can host and test the application using an IaaS provider, then refine it or go in a different direction without having to take on the full cost and responsibility of purchasing and maintaining onsite data centers.

IaaS business advantage

IaaS frees up time to focus on your organization’s business objectives, as opposed to your IT infrastructure. Setting up, managing, and updating traditional on-premise data centers is time-consuming and costly. IaaS gives organizations the flexibility to prioritize their business goals.


By combing the computing power of a significant number of cloud servers, IaaS providers are less likely to disrupt organizations with performance issues or downtime due to spikes in demand. Furthermore, the IaaS server model protects against single points of failure. If one server fails, there are multiple other servers that can deliver that resource in its place.
