While the business benefits of moving to an enterprise cloud are clear – increased mobility, reduced hardware spending, better data security and disaster recovery – the benefits for those in an IT department may not be as well defined. However, as Cloud Tweaks contributor Moassam Adnan stated, the cloud provides numerous computing benefits that make an IT manager's life easier.

"Cloud computing is not limited to web hosting. It has a full array of computing power that can span private networks as well," Adnan wrote. "Cloud computing is really just a representation of what it could be. As an IT manager, you get to choose what you want cloud computing to do for you. This means that the concept is really open-ended. The features allow for continual expansion and upgrading, without the need for server technicians to add additional servers."

Ultimately this leads to better server productivity. The setup allows those in IT to handle server requests more efficiently, never running out of resources, as those are offered by the cloud service provider to meet any requirements needed. They can also deploy new upgrades that would've normally taken months in just days. The only big job required of IT is monitoring the infrastructure, possibly requiring IT staff to get some additional training.

IaaS cloud perfect for many businesses
Infrastructure-as-a-Service is an effective cloud model for businesses looking to reduce hardware in their data centers. According to Business 2 Community contributor Brian King, IaaS clouds are the perfect way to cut costs.

The cost effectiveness of the IaaS is two-fold. One, the company is able to get rid of old servers or other hardware that needs to be replaced by moving those infrastructures to the cloud. This also includes any additional support that was needed to run those systems. Two, the pay-as-you-go model of many cloud service providers is ideal for a lot of businesses. Companies are able to pay for the services they use, and can scale them based on need. This is better than a flat-fee model that forces an enterprise to pay up front for services they may not use. IaaS also meets a lot of other business demands.

"IaaS serves the lower level of need for business, the underlying computational power or the storage facilities for large amount of archived data," King wrote.
