What is IaaS?
In the most basic sense, IaaS means provisioning basic computing resources such as storage, hardware, networks and servers over the Internet. The actual physical infrastructure of your Information Technology systems moves outside of your organization and into a service provider’s environment.
IaaS works well as a foundation for similar technologies, such as Software as a Service and Platform as a Service.
Let’s take a look at three specific benefits Infrastructure as a Service may be able to provide to your organization:
- Elasticity and flexibility. IaaS leverages the elasticity and flexibility inherent in the cloud to deliver infrastructure to your organization. It lets you choose when, how and which computing resources are going to be consumed, which will be scaled up or down based on the actual demands of your organization, and doing so in real time. Because it’s your IaaS provider that has to be concerned with configuring and maintaining the infrastructure, you don’t need to be bogged down with upgrades, and you can instead focus on managing your business applications.
- Reduction of capital expenditures. When you have IaaS, you pay as you go. You don’t lay out large amounts for new hardware or software. You pay the IaaS provider only for the resources you use during a given period. This makes IaaS an attractive option for small and medium-sized businesses, but also for the enterprise that needs state-of-the-art infrastructure to truly support their business needs.
- Short term gains. While the flexibility and lower cost of IaaS tends to pay off over the long term, you can also leverage IaaS in the short term. You can use it, for example, to boost seasonal marketing campaigns or particularly busy times of the calendar year, and scale back down when the demand for resources scales back down.
Most businesses can make a good case for at least considering Infrastructure as a Service.
