What’s Up With IaaS?

Cloud services are typically grouped into 3 categories. Software as a Service is the best known option since hundreds of vendors in HR software and related business spheres provide their services via this model. Our Universal Onboarding program is an example of an application that can now be accessed in a cloud-based format for clients who want to get on board with this technology. Platform as a Service is becoming popular with both vendors and end users who need an affordable and readily scalable base on which to construct custom applications. Infrastructure as a Service (IaaS) is the third category. This sector is poised for exponential growth as organizations migrate from legacy server systems to virtual servers.


More Companies are Switching

According to CIO.IN, 25% of organizations are currently planning to take advantage of IaaS through third party providers like Amazon and Google. These companies use virtual servers to shift loads around the cloud and make the most of available resources minute by minute. This is in stark contrast to traditional data centers that typically have a great deal of infrastructure available at all times but rarely operate anywhere near peak capacity. Legacy data centers have to be constructed to factor in plenty of capacity for those times when demand increases, and customers pay for the assurance of this availability even when they aren’t using it.

The Cloud IaaS Difference

With cloud infrastructure, usage is metered. Customers pay for what they use and can scale up or back at any time. This is particularly useful for IT in the development and testing of new applications that may require additional server space on a temporary basis. The organization doesn’t have to invest in permanent infrastructure upgrades to avoid interfering with other processes on their existing servers. For inward facing applications such as HR, IaaS could offer an organization the ability to explore new training and development programs cheaply and effectively.

The corporations running the cloud infrastructure have access to such a massive quantity of server resources that available capacity for their entire customer base is more than adequate even when demand is high. At the same time, it costs a fraction of the expense of running a legacy server system in terms of energy. This means customers often pay much less than they would when running their own servers in-house or outsourcing to a non-virtual infrastructure provider.
