If you have been paying any attention to current IT trends over the past couple of years, there is no doubt you have heard the term “cloud computing”. There is also no doubt that it’s 1 of the hottest IT buzzwords floating about out there, these days. But what specifically is the cloud, and what are some of the positive aspects, and precautions, your business ought to take when evaluating regardless of whether to use cloud computing?
To put it merely, cloud computing is utilizing a cluster of resources that may possibly or may not be local to your IT infrastructure to perform IT functions on demand. Feel of it this way – in the past, a lot of organizations had dedicated servers that performed specific functions, such as financial backend processing to a project. Firms had to strategy for peak usage, redundancy, growth, etc. This generally meant that companies were investing huge amounts of cash in IT infrastructure, that could sit idle for lengthy periods of time.
Cloud computing assists with some of these issues by providing resources that exist not as a singularity, but as a pool. These resources may possibly or may not be owned by your company – some of the biggest cloud resource providers appropriate now are Amazon and Microsoft. Instead of having a dedicated box or multiple servers, when programs or other IT processes need to have resources, they just reach out to the “cloud” and request them.
These resources can grow and shrink dynamically in numerous circumstances. Require more disk space? Just request more. Want much more processing power? No difficulty. It’s like a pay-as-you-go model. You are only paying for what you want, when you want it.
Cloud computing also helps with redundancy and failover as you are no longer dependent on a single machine. The cloud is allocating resources from the pool of available resources that might be located at multiple data centers about the world.
Of course the greatest concern with the cloud is the security and privacy of data. Public clouds, such as those owned by Amazon and Microsoft, are situated outside of your corporation, and there are concerns about the privacy and security of data. There is also the question of, “what occurs if the cloud provider goes out of enterprise tomorrow?” – can your corporation just switch providers, or are you so integrated with that provider it could trigger significant issues?
To address some of these concerns, companies are seeking at private clouds. These private clouds work in considerably the very same way as public clouds, but they are generally owned and operated by the business itself. The corporation might have servers and other resources that are not dedicated to certain tasks, but rather are portion of resource pools that are offered for any IT process to use. You often see such a setup implemented with virtualization technology and blade computing. It can bring many of the benefits of the cloud into the organization even though still supplying peace of mind about security and data integrity problems.
As the cloud continues to grow in popularity, we will no doubt see a lot more companies beginning to take benefit of its capabilities. You most likely are already making use of some cloud functionality, and may even know it. Web mail providers such as Yahoo, Microsoft Live and Gmail, and photo sharing services like Flickr all use some cloud functionality. The cloud is everywhere — just be careful to watch for occasional thunderstorms!
