Cloud Computing: New Concept of Distributed Computing

Cloud Computing is a new concept of distributed computing which is a major revolution in the world of IT. Within the last few years, many emerging technology Buzzword. Gartner (www.gartner.com) a leading research institute, in its annual report, 2008, released "Gartner's Hype Cycle Special Report 2008". In the category of emerging technologies, Gartner stated that "Cloud Computing" will reach its maturity level of about 2 to 5 years to come. Based on these reports, this time, Cloud Computing is still regarded as a technology buzzworld still face the problem of market adoption.

In general, Cloud Computing can be described as follows:
• Computing and information-related technologies are no longer needed or owned by the company and stored in the company's own environment. This also means that any company can use business applications, without having to buy a license, buying servers and storage needs, purchase a database license, and buy equipment and data communications networks. Company is contacted and ordered the company applications cloud computing provider, signed a contract and register the user who will use the application, and then applications can already be used by users with access to the Internet via a browser that has been set.

Apart from the many problems of technology adoption in the marketplace and its mature yet these solutions, while providing cloud computing promises irresistible to many companies.

In the case of technology ownership, the company actually has two choices ie, have the technology or hiring technology. For companies, the cost of rent will cause what we call OPEX - Operational Expenditure, which is routine in nature and tend to stay. While the cost of buying will cause CapEx - Capital Expenditure, its only once, when bought, but is usually accompanied by other costs such as maintenance and capital depreciation costs. Many companies prefer OPEX costs than CapEx. Based on the cost concepts above, cloud computing is also very inclined to use OPEX cost model.

There are some things that is the reason.
1. Companies that adopt this technology does not need to buy or have the technology products, such as servers and storage.

2. Companies that buy the solution-based business applications cloud computing-based business does not need to buy a license.

3. The company also does not need to have an IT department that monitors servers, storage, networking, and business applications.

In general, cloud computing is the latest form of the combination of the three concepts of technology: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Cloud Computing also has characteristics of the three concepts of the technology: Grid Computing, Utility Computing, and Autonomic Computing. All IT services based cloud computing is usually a business application services online. It also illustrates well that this cloud computing service infrastructure that tend to have complex behind it.
