Advantages and disadvantages of the pattern of "cloud computing"
1. Advantages
The advantages and strengths below have contributed to help the "cloud" computing models are becoming widely applied all over the world :
a. Fast processing speed, give the users the quick service and cheap price based on centralized infrastructure (cloud).
b. The cost of the initial investment on infrastructure, human resources and select the user's cloud are reduced to the lowest level.
c. No longer depends on the geographic location and equipment, allowing users to access and use the system via web browser anywhere and on any device they use (such as a PC or mobile phone...)
d. Sharing of resources and costs on a large table, bring the kind of handy for users such as:
� The focus of infrastructure in a position to help users lower the cost of investment on equipment.
� Faster processing capacity by resources are focused. In addition, users do not need to invest in human resources management system.
� The ability to harness and installed performance better 10-20% compared with conventional personal computer.
e. With high reliability, not only for the common user, cloud computing fit in with the high requirements and continuity of the company business and scientific research. However, a few major services of the cloud sometimes fell into overload, which makes the operation was delayed. When fall into this State, the user does not have the ability to handle incidents that are attributable to the professionals from the cloud processing.
f. Ability to expand, helping to improve the quality of the services offered on "the cloud".
g. Security capabilities are set in good due to the focus on data.
h. The application of cloud computing easy to repair more than because they were not fixed on a cheek c�a computer would. They are also easy to install and friendly support in terms of features.
i. Resources use of cloud computing has always been managed and statistics on each client and application, each day, each week, each month. This ensures that the price of each weight by the cloud service provided to a user may select as appropriate.
2. Disadvantages:
However, this computing model still had a number of disadvantages:a. Privacy: The user information and the data are stored on the cloud are guaranteed to be private, and whether such information has been used for some other purpose?
b. Availability: does the cloud services have been "suspended" incidentally, users cannot access the services and data in the time period which affect your work?
c. Data loss: A few services store data online on the clouds suddenly stop working or not continue to provide the service, users should backup their data from the "cloud" on your personal computer. This will take more time. Even in a few cases, for some reason, the user data is lost and cannot be recovered.
The data contained on the "cloud" will have to entrust the entire "fate" for "cloud"
d. Data portability and ownership: A question arises, whether users can share data from cloud services to other cloud services? Or in the case of not wanting to continue using the services of supply cables from the cloud, whether users can back up their data entirely from the cloud? And how can users be sure that cloud services will not cancel the entirety of their data in case of decommissioning services?
e. Security: problem focused data on the "cloud" is the effective way to enhance security, but on the other hand also the concerns of the users of cloud services. Because once the cloud is attacked or break, the whole data will be captured. However, this is not really a matter of "private cloud", by data theft attacks probably was the problem encountered in any environment, even on the personal computer.
