Infrastructure as a Service (IaaS) is a form of cloud computing that provides a virtualized resource over the internet. IaaS is only one of the three main categories of cloud computing. The others are SaaS (Software as a Service) and PaaS (Platform as a Service).

How IaaS works

A cloud provider hosts the infrastructure components that are traditionally present in an on-site data center. This includes the servers, storage, and all the hardware for the network. There are added services that can be covered with IaaS. These are security, load balancing, recovery, monitoring, backup, and storage resiliency.

Why use IaaS?

Many companies look into this option because it can be more accessible, faster, and more cost-effective to a business. Organizations can use this infrastructure without the need to purchase, manage, or support the underlying infrastructure needed such as servers and other data center equipment. IaaS can be easily scaled up or down depending on your requirements and you only pay for what you use. Each resource is offered as a separate component and you can pick and choose what your business needs.

Common Uses for IaaS by Businesses

Storage, backup, and recovery – As a part of a layered approach to cybersecurity, it is recommended that a backup of your data be stored off-site. This will allow you to resume business should something happen to the physical location of your company. It can also handle unpredictable demand and storage that is needed, not to mention the ease of planning and management of your recovery, should it be necessary.

Web apps – IaaS provides all the infrastructure to support web apps, including storage, web and application servers, and networking resources. Organizations can quickly deploy web apps on IaaS and easily scale infrastructure up and down when demand for the apps is unpredictable.

Significant data analysis – Big data is a popular term for massive data sets that contain potentially valuable patterns, trends, and associations. Mining datasets to locate or tease out these hidden patterns requires a tremendous amount of processing power, which IaaS economically provides.

The advantages of using IaaS are many but some of the highlights include:

  • Reducing ongoing costs of your IT infrastructure
  • Disaster recovery simplified
  • Business continuity
  • Quicker response to changing information technology demands
  • Higher cybersecurity
  • Allows you to focus on your company

Reliability, cost savings, and the services you require should all be considered before shopping for a provider. Employing IaaS is not just for enterprise-sized business. There are many options available for small to mid-sized companies.
