Cloud Computing

1. Understanding Cloud Computing

Understanding Cloud Computing, Cloud computing or cloud computing is the definition for grid computing technologies (grid computing) that are used in the mid to late 1990’s. Jargon cloud computing began to emerge at the end of 2007, is used to move a service used daily to the Internet, not stored on the local computer again.

Email is available in the form of web mail is a very small example of cloud computing technology. By using email services like Gmail and Yahoo Mail, people no longer need to use Outlook or other desktop applications to their email. Reading email with browsers enabling done anywhere along the existing Internet connection.

In 2007, other services including word processing, spreadsheets, and presentations have been moved into the computing cloud. Google provides word processing, spreadsheet and presentation applications in the cloud computing environment and integrates with Gmail and Google Calendar, providing office environment on the web (or in the cloud). Microsoft and other companies are also experimenting with transferring programs into the clouds to make it more affordable and more accessible to the user’s computer and the Internet. Software as a service (Microsoft’s term for cloud computing) is a very new stuff for most people at Microsoft. 

Cloud computing is currently very popular, apart from major players like Microsoft and Google’s software, other companies popping up just to provide cloud-based services as a substitute or refinement applications on PCs today. Some of these companies was, an online office suite,, is a site devoted to online records, and, online task management.

Computing technology and new programming techniques or changing rapidly developing technique, the goal of cloud computing will make the technology seem to be very easy in the eyes of users and make it as simple as possible. Very rapid development of Internet-based current with the booming blogging and microblogging and social networking service that aims to find new ways to help individuals and businesses to be able to communicate with one another in the cloud computing arena.


There are at least several conditions that must be met:

2. Service is elastic / scalable, where users can add or reduce capacity, types of services they want at anytime and the system can always accommodate the changes.Let users subscribe to Internet in the bandwitchnya 512KB / s and want to add speed to be 512KB / s then asks the user to call customer service to increase customer service bandwitch then respond by changing bandwitc to 1Mb / s.

3. Fully managed service provider / providers, users only needed by the personal computer / notebook plus internet connection.

2. Benefits of Cloud Computing

The greatest advantage of cloud computing that we provide virtually unlimited resources in a network that end, extensive polymerization of the world’s natural resources, as long as there is a network, we can all over the world anytime, anywhere access to resources. Through our own terminal in any case, reach results.

Secondly, to improve the security of cloud computing, data storage in data to maintain a professional corporate data centers, because we no longer have the virus, the system is not secure and was devastated. That is not no longer has a corporate network administrator to this position out.

Third, do not often do the replacement of equipment, because the cloud computing needs of the terminal device is very low. Cloud computing development to the adult stage, different devices can achieve data sharing and application, it sounds very good.

3. Problems Cloud Computing

1. Access to continue in the hands of others
Cloud computing model fully the data stored in the equipment service vendor Tigong cloud which means that your data is the highest access Quanxian cloud providers, not of yourselves, but on information security challenges.

2. Compliance
In “Sarbanes – Oxley Act,” the power of the era, companies have a responsibility to apply a strict level of data monitoring and archiving. Even a company with an external cloud computing services provider signed a contract, this rule still requires a responsible company. Cloud computing service providers must submit an audit and security certificates, to ensure that the other parties to fulfill contract commitments.

3. location data
With cloud computing model, your data will be placed throughout the world, maybe Beijing, New York or London, may apply in three places at the same time, you must ensure that the service provider cloud, they are willing to give a commitment contract, in accordance with some privacy laws.
