Infrastructure-as-a-Service (IaaS) is a type of cloud computing. In this model, the service provider manages all of your company’s virtualized IT infrastructure, including cloud-based servers and storage solutions. IaaS offers a number of benefits that traditional IT infrastructure solutions lack. However, some companies unfamiliar with the technology are hesitant to make the switch.

Here are three reasons why IaaS might work for you:

1. Deploy Infrastructure Faster

Purchasing and deploying physical equipment can take weeks and sometimes even months. Ordering, assembly, shipping, configuration, and installation all require time and resources. With IaaS, all you need to do is fill out a web form. Requests are processed almost instantly. Your company’s system administrator can provision and configure a new virtual server in a fraction of the time.

2. Scale Resources Easily

Scaling has different meanings in the world of IT. In this context, it means adjusting resources such as processing power, memory and storage. A major strength of IaaS is its ability to scale in real time with the needs of your company. This ability is simply not supported by physical IT infrastructure.

IaaS offers two scaling solutions. One is basic manual scaling. This allows companies to adjust their own computing resources. The second is dynamic scaling, which automatically adds and removes resources as your needs change. This takes the hassle out of scaling and ensures you have the right resources when and where you need them.

3. Cut IT Costs

Purchasing and maintaining physical infrastructure can be extremely expensive. After the up-front costs for the hardware itself, companies must account for ongoing operational expenses. These include hiring and training qualified staff, renting or purchasing space, and electricity for powering and cooling the hardware. Physical infrastructure also limits your ability to quickly and cheaply adapt to changes in the business environment. Forces such as economic instability and the rapid pace of technological advancement make it difficult to estimate future needs.

IaaS offers low or zero fixed costs, depending on the provider. Pay careful attention to fixed fees outlined in any contracts offered by IaaS providers. IaaS is generally billed on a metered basis, which means that companies only pay for what they use. This benefit alone is often enough for companies to make the switch.

Overall, companies find that eliminating the need to manage physical infrastructure results in huge cost savings. This gives companies the freedom to redirect resources where they belong: on growing and expanding their business.
