Public cloud vs Private cloud which data is more secure?

In this has evolved to http://www.aliyun.com/zixun/aggregation/8416.html "> Web3.0, at the same time, the information explosion of the era, the Internet in the arms of each individual is in milliseconds as a unit of time to receive the mass of T space units of data, 10 years ago we can not imagine the data events in today's so natural hair in each individual body.

For example, when you enter the home page of the traditional portal, you find that the content appearing on your screen is quite different from that of your neighbour's little friend the first time you may be surprised to shout the website bug, but when the eyes of unfamiliar disdain quickly focus on your point, but you can not speak again, with the accumulation of time, Also gradually become accustomed to, all this simply because the portal before you is not a portal of thousands of people, but in line with your browsing habits personalized portal.

Yes, no one persuaded you, your own happy surrender agree with this new gadget, this is the charm of large data mining, so that information to reach each target audience time greatly shortened, the efficiency doubled, or based on both sides of B and C benefits. Of course, all this premise should be based on the user out of the voluntary situation, the data itself naturally revealed traces of the result, if everything is desired, the world of course more beautiful, however, the contrary, any emerging things have a dramatic symmetry of the opposite. Other data events often haunt everyone's daily lives, for example, you are good at enjoying the beautiful experience of shopping, suddenly the phone is inexplicable rang up, not in the contact area of the number, so that you are not connected nor not, in a rush to make the answer to hear a decision, the phone another noise in the background sound, Tender voice is clearly asking if you want to buy shops along the street, you angrily pressed the Hang machine key, when you are about to the next to the best friend to spit, only to find that this is the usual day, and even more shocking is that the door of the book kiosk is selling your contact with the industry elite contact list, instant black lines countless. What's wrong? Very simply, your data has been leaked!

This is certainly not a voluntary act, and we can be certain that, for a long time to come, the scene of the uproar over your data leaks is as often your nightmare as the plight of a Hong Kong-Taiwan star. So let's look at this from a different point of view, the personal data of these events, it seems that there is no time and again to find a solution to deal with, that change as a business? Is the company's data in the traditional information under the protection of the armor is really foolproof?

In a business, regardless of its size, who will be the most concerned about the company's data security role, the answer at a glance, Cio,it manager and the boss himself, in the traditional enterprise information architecture, data security is the above role in choosing to use any software products, the most need to consider one of the problems, Let us take a moment to cross the traditional single line deployment of this ancient information totem, followed by a fixed thinking of the emergence of the so-called public cloud is not safe, private cloud security is widely circulated.

For this problem, in fact, many people fall into a misunderstanding, that is, if the hardware is mine, the data inside is mine, this is safe. The problem is, like the personal data leaks in the previous article, the data itself and the real thing is very different, the data is made up of binary 0 and 1, no matter where you put it, is not in fact not determine whether he is safe or not, because the mobile data does not need cost, only need a network of transmission to complete.

So, whether you put the data in the so-called own machine, or hosted in the third party IDC, as long as exposed to the public network, in fact, can be invaded, the data is theoretically unsafe. If you put data on a completely isolated host, there is no external interface, including USB port, so that is absolutely safe. However, with the development of the Internet, including the evolution of mobile Internet, a completely no external interface of the device is not valuable, and a hosted in IDC, or the public network access to the security of the server is that you need to invest a lot of resources to safeguard maintenance, such as the previous OpenSSL loopholes, If you don't handle it in time, you may have lost the data. In addition as the internal data managers, in fact, is very good to be bought under the line, such as an institution of the IT department of the group by their opponents dug away, of course, not only people, but also data.

So the real sense of data security, those who have the Internet interface platform is also good equipment, in fact, all need a strong security, and at this point, the public cloud is far more secure than the private cloud, first, the public cloud Platform unified maintenance, unified management, including a unified firewall, than some of the naked running on the Internet host must be a much higher safety factor. Second, the provision of any public cloud services companies, security is the lifeline of this type of enterprise, the contractual relationship between the two ends of the service to ensure that the acceptance of the service side of the data security is connected with the service provider Lifeline. Obviously, hosting the server in IDC security is not the responsibility of IDC room. Third, the public cloud service itself can effectively deter internal managers, because all data change operations records are in the hands of third-party service providers, not in the hands of an internal manager.

There are many things in this world that are converging in nature, for example, the security of data and financial security, is essentially one thing, the existence of bank money must be more than in your own vault of money to be safe, even if the bank is stolen, the bank that receives your deposit will pay you, and the same as cloud services, with a contract guarantee, You have at least a corresponding authority to restrain the service providers, at the same time, in order to perpetuate the difficult partnership, Third-party service providers in the framework of contract and legal spirit, but can provide more quality services.

Obviously, if you're really a key arranges in your business that is concerned with data security, when choosing a cloud service, it is not a simple distinction between a public cloud or a private cloud, but rather a look at what kind of security promises a third party provides to you, and a signature, if so, you can now start your own cloud strategy deployment.
