As organizations increasingly depend on advanced, high-functioning computing systems for most or all of their critical business operations, it's imperative that IT operations become faster and more efficient in response to this changing landscape. Effective enterprise cloud computing will rely on IT as the focal point of the new system and will only be able to grow as quickly as the IT infrastructure allows. Expanded IT functionality is not the only reason why enterprise IaaS clouds are the logical next step for businesses looking to become more agile and data secure, but it is certainly one of the most compelling.

Here are two reasons why the IaaS cloud can be a vital pillar in the development of a more intelligent IT approach.:

1) Centralized operations
Over time, companies increasingly augment business models and operations with new technology, systems, interactive components and specialized staff to make all of these things work in concert. While a business may think that it is running at optimal capacity purely because everything is functional, it can easily lead to complacency about how much things have changed. As more working parts are added to the existing machine to accommodate each new innovation or strategy, there is often less attention paid to the structure on a holistic level. Furthermore, attempting to penetrate deep into existing computing systems with the objective to reorganize can be time-consuming and costly. Businesses don't want to dismantle systems that they've already built up.

Think of the switch to an IaaS cloud as a smart choice for a much-needed house-cleaning. A recent TechTarget report dissected the problems associated with increased specialization and silo-ing of networks and systems. This stratification means that different departments are less likely to collaborate with each other, and could even be approaching the same problem from different perspectives, which can lead to redundant efforts and counter-productive actions.

The report cited IDC statistics that stated that organizations with consolidated IT can benefit from a 33 percent reduction in downtime incidents and a 17 percent rise in overall IT productivity. IaaS offers better centralized operating systems and consolidated applications, so that requests and systems treatment travels through one source and is more visible to all.

2) Increased virtualization
As the amount and scope of information necessary to run and further cultivate critical business applications grows, managing storage and disaster recovery plans can become a more time-intensive and cumbersome task. Having to back up each machine, server and even individual disks contributes to slow going on the front end, and restoring each as part of the recovery step could create bottlenecks and slowdowns on the back end, according to Virtual-Strategy Magazine. That's a significant chunk of time spent on what is essentially the manual labor of enterprise IT operations.

Virtual machines, on the other hand, are much easier to back up automatically and reduce restoration exertion, Virtual-Strategy Magazine stated. Virtualized data can more easily be moved between servers and networks in the event of one failing, and virtualized machines can be shifted to another host if the original one has been hit by a disaster without fear of compromised functionality.
