Cloudy with a Chance for Rain: How Cloud Computing is reshaping the Role of IT Edit

Cloud


The Sky Ahead Us is Full of Clouds Edit

Brief explanation of how Cloud Computing is becoming a dominant set of technologies that should be fully understood by IT Managers in order to apply them correctly, make the most of it while keeping the risks low


What is the Cloud? Edit

Cloud Computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, application and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models [1]

Need to add additional content to explain characteristics, service models and deployment models in a simple way.

Why Cloud Computing Matters Today?Edit

In today’s competitive globalized world, speed is everything. According to a HBR global survey sponsored by Microsoft [2] in which about 1,500 organizations and leaders participated, 44% identified Cloud Computing as a key factor to achieve agility.In today’s competitive globalized world, knowledge is power. Small businesses can connect via the Internet to the widest range of tools, software, and programs once accessible only to the most profitable, deepest pocket, blue chip stock. Startup costs for any entrepreneur have been significantly minimized through cloud computing. First, collaboration has been

significantly improved. Over 66% of small to medium sized businesses need to allow their employees to work anywhere, anytime (1). Any smartphone, tablet, notebook, or PC can be connected to their company's cloud to collaborate with coworkers, vendors, suppliers, or customers. One rosetta stone can be placed in the cloud for all to build upon. No longer is there a need to email multiple versions to various individuals in hopes the "master" copy is still intact. Secondly, as growth ebbs a

nd flows the cloud will allow you to manage up or down your business's need for applications and software. By managing this growth (or contraction), you are managing your ability to meet your customer's needs while maintaining a bottom line. Thirdly (possibly most important), the cloud allows companies to manage their costs more efficiently. IT Departments are able to add and subtract programs, hardware, or memory as needed, instantaneously. Having various licenses for num

erous software applications unsure of the need for each, can now be scaled into and out of, as necessary. This management of software needs will save businesses significantly. Next, cloud based computing offers computer back up services. Quite possibly second most important after business profitability is protecting your information from theft, file corruption, natural disaster, etc. The cloud offers routine or automatic back up services with geo-redundant capabilities which is the ability to back up your company's information across many data sites, across many locations. Lastly, by putting your software needs in the cloud you increase the reliability the service offered because cloud based services have dedicated IT personnel to manage your needs, immediately. Since cloud IT Departments are able to access and troubleshoot your problems immediately, the company can get back to work faster. Having to call on-site IT managers will now be a thing of the past. Trouble tickets will be located in the cloud, attended to immediately. As you can see, there are many reasons to consider basing your software needs in the cloud. All will contribute to making your business run faster, more efficiently, and more competitively.

The Challenges of Flying through Clouds Edit

This is the real beef. An analysis of that are the common issues facing in dealing with the Cloud. I originally thought that reference [3] would help, but that article is more about the challenges the Service Provider faces (HP, Amazon, Microsoft) when servicing the Cloud.</span></p>


Weathering the Storm Edit

I think it is interesting to list recommendations that would help an IT manager to avoid pitfall. Performing due diligence such as understanding if the business is prepared for the Cloud or not, the best Cloud Service and Deployment models applicable to the company, and the misunderstanding that moving to the Cloud equals zero management or could be cheaper than other solutions is among the things I thought to add here.
