Business applications are increasingly having IT infrastructure provider as one of the main part of the organization’s backbone. IT infrastructure refers to the hardware, software and applications that an organization uses to run its day to day business. Due to the major role it plays in enterprises, IT companies have come up with a better solution which entails providing the infrastructure as a service. This concept is known as Infrastructure as a Service (IaaS).

What IaaS does is, lets a third party come into an organization and manage the hardware, software and storage of the enterprise’s data. This has been made easy with the advent of cloud computing and virtualization technologies and has increased the customer base for IaaS providers. Other services almost similar to IaaS and that rely to the mentioned technologies include Software as a Service (SaaS) and Platform as a Service (PaaS). The service provider automatically becomes an extension of the organization.

Outsourcing the management of IT infrastructure to an external organization can serve to increase an enterprise’s output in many ways as it is cost effective, increases a company’s efficiency and improves its chances for beating compliance control. The benefits got from outsourcing IT infrastructure majorly result from the fact that it is the cloud being used by the service providers to manage the IT infrastructure. They include:

  • The organization gets confident that infrastructure is always up to date and can keep up with the innovative and competitive nature of the modern world.
  • It is cost efficient. This is due to the fact that the need to repair, update, maintain or even replace hardware and software is offloaded off the shoulders of the enterprise. The organization will also need less IT staff due to the small IT infrastructure that remains on its side. Most IaaS providers also operate on a pay-as-you-go policy which is of benefit to the organization as no fixed monthly or annual fees are needed.
  • The model with which IaaS is built allows for scalability. This maximizes returns as the infrastructure can be easily scaled up when there is a high demand for the resources and get easily scaled down when the demand is low
  • A business enterprise can use the ability for the system to be scaled up to his advantage. The organization can market there goods faster and beat competition by ramping up resources since the model is scalable.
  • Updating the system becomes easy and less time consuming as it just needs to be updated at the server’s end. Repairing and patching software also becomes centralized. The centralized system also allows for a person to access data from any point through a network as the data is backed up in the cloud. The backup provided is very reliable too.

A drawback with IaaS is that, since the system relies on computer networks, services to the customers may be affected In case the network’s down speed goes slow or the network experiences difficulties. Examples of well-established IaaS providers include Amazon, Google, IBM and Rackspace.
