Cloud Computing Overview

Cloud Computing Overview, Most likely in the next five years, the popularity of cloud computing within the enterprise and the government would increase significantly. However, Cloud Computing itself is not the answer.
Cloud computing has grown in popularity in the industry since early 2007. In nontechnical terms, I would define a cloud as a common (C) (L) OCATION INDEPENDENT (O) nline (U) TILITY in (D) on-demand service.
Recently, I’ve been involved in discussions about social networks, especially Facebook, in terms of cloud computing, because I’ve been an evangelist of the cloud a little over a year and I am shocked by the pessimism of a Nigeria raises many technology experts in this discussion.
First, there have been thousands of variations in the definition of the cloud. Everyone has a different perspective and understanding of technology and misconceptions surrounding the issue was evident when Steven Ballmer, CEO of Microsoft, had communication problems of his company’s strategy & infrastructure cloud, Microsoft Windows Azure to a select group of C-level executives last November.
The vagueness surrounding this “phenomenon” is mostly attributed to what I call the “hype cycle.” Since February 2007, Cloud Computing has been a buzzword for companies and governments are hoping to save costs and reduce energy consumption and carbon emissions.
For my audience no techie, Cloud Computing is essentially outsourcing, pay you-go, on demand and in any part of the Internet experience that is always offered as a service. Even if you are not an entity that adopts the technology good or jargon a “digital immigrant”, you will be amazed at how much the interface with the cloud.
Mobile phones that have the email addresses (Yahoo, Windows Hotmail, Google Mail, etc) that we, IM (BlackBerry Messenger, Yahoo, Windows Live, Nimbuzz, Meebo, 2GO, eBuddy etc.) we use to communicate on the go, are typical examples of cloud computing services.
It is due to the fact that the physical layer of the OSI (Open Systems Interconnection) model has been extracted. On the plain, for example, that means a subscriber of Airtel should not worry about where the server serves / she is, but his / her focus should be oriented service that has been delivered.
Nor is there a Gmail user to worry about where Google’s server because it is completely irrelevant. This generation is a generation of services. All that is now offered as a service and the benefits of being cared for is essential to avoid.
From a technical perspective, the Cloud Computing is divided into three main levels, namely:
1. Software as a Service (SaaS): This is basically what everyone already is in the form of Gmail, Yahoo Mail, WordPress, search engines, Wikipedia, Facebook, Twitter, etc.
2. Infrastructure as a Service (IAAS): This is an offer from Amazon was a pioneer as the great father with Elastic Compute 2 (EC2). Developers and system administrators an overview of calculation, storage, queues and other resources and run their applications with the least amount of limitations. This is the most powerful type of cloud in that virtually any application and any configuration that is suitable for the Internet can be assigned to this service. Microsoft’s cloud infrastructure is called Windows Azure.
3. Platform as a Service (PaaS): This is the last entry, which provides an application platform for developers in the cloud. Developers write their application of a more or less open specification and then upload the code in the cloud.
Highlighting all the benefits of cloud computing to businesses, individuals and governments can not be over-emphasized. Cloud Computing in all facets of budget releases handcuffed by IT expenditures. Instead of buying software licenses for new employees and locations, companies only have to add accounts to expand computing capacity.
Governments benefit from it because the pool of all industries as diverse as a whole and would ensure openness, accountability and prudence. For example, the Government of Nigeria can create a cloud that citizens pay their bills shelter, water and electricity in a central platform. Nigeria police can create a cloud infrastructure is appointed in this case, the Intellipedia Nigeria ® that have sub systems such as cloud Police ® ??reporting software, which inadvertently brings the claim that the role of a base central database and facilitates the management of a crime less complicated issue.
Over the times and trends, some young Nigerian entrepreneurs are creating overly ambitious private infrastructure cloud is beginning to generate positive vibes. The first is the Naija Bank ® information which when completed will be the largest database of Human Resources in Africa, with a capacity of more than 80 million users and second www.traffic.com.ng still is in its beta phase and after completion would provide traffic report describing the GPS coordinates of every corner of Nigeria. All you have to do as an end user is connected to the cloud and enjoy these services.
Most likely in the next five years, the popularity of cloud computing within the enterprise and the government would increase significantly. However, Cloud Computing itself is not the answer. The key to achieving great success is for businesses and governments to use powerful software to integrate existing infrastructure facilities in the cloud.
