On the three Sins of cloud computing: Offline fault privacy and security

As you know, cloud computing has the cost, the resources to expand, flexibility and other advantages, but anything like a coin has two sides, cloud computing There are some disadvantages you must know, service providers are trying to put you on their products, but do not force you to maintain the loyalty of the right, but the technology provider has a way to drive you to maintain loyalty , the following are some of the drawbacks, suggestions, and reminders about cloud computing.

Analysis of cloud computing disadvantage: Offline fault privacy and security

Offline

The first thing to mention is offline, this is the first and most important disadvantage of cloud, because if you do not have continuous network connectivity, many features you can not achieve, you will find that you can not receive mail, can not edit the file, but also unable to retrieve the backup.

Do you want to say that Google has published the operation of offline applications? In fact, Google Apps will only allow you to watch emails, itinerary, and files offline, and you're editing them, which may not be a big problem for you, but the editor of the file is a huge problem for you, You will find that these features are limited to Google's Chrome browser, Firefox and IE browsers are not able to achieve these functions, which to some extent also form a user binding.

Google also said it would provide offline editing, but that would also face the same binding problem, since only Google Doc could work. People at work want to use Microsoft Office, Open Office, or Google Doc in accordance with their customers ' preferences, rather than being bound in any way.

Of course, Google also says it will provide offline editing, so users will face the same binding problem because only Google Doc can run. The user, at work, wants to use Microsoft Office, Open Office, or Google Doc in accordance with the customer's preferences, rather than being limited to any one way.

Fault

Unlike offline is the failure problem, that is, the service for some reason failed to provide services, Google, the current free services provided by Google does not have any support, so once the failure problem, users can only pray that in the event of a major problem, these services can be restored as soon as possible.

Do not pray failures do not occur, because the fault really happened, the recent days of Microsoft and Google's cloud services have been different degrees of failure, Google doc offline one hours, Microsoft's Hotmail, Office 365 and SkyDrive disconnected 3 hours, Amazon also has a serious downtime, and these services used to have more disconnected records, although it does not prove how unreliable they are, at least to indicate that the fault occurred sooner or later.

Privacy and security

But when someone has mastered your information, you have to worry about the problem is not only the problem, privacy and security are you have to consider the problem, the Internet world today, the hacker attack is simply a commonplace thing, Sony on this is deeply hurt, cloud computing security problems when the global problem, Many cloud service providers currently lack real security planning.

Is cloud computing really good for consumers? Yes, there are already a large number of users have been using cloud services to backup files, accumulated a considerable amount of data information. But the potential security issues should not be overlooked, so it is recommended that users in the selection of service providers more time to select a high degree of trust service providers, but also pay attention to these cloud service providers will be closing, even if it is less than the risk of your hard disk damage.

Finally, to remind you to use the cloud services correctly, do not believe too much hype side, this is the wise.
