Data loss due to disk corruption Grand Cloud host propaganda was accused of exaggerating

A web site down, for false cloud host poured some cold water.

This Monday, the Travel service website "The Backpack Rabbit" appears the unusual visit, as the Operation Manager's Cao Ming hurriedly calls Sheng's customer service personnel. Sheng customer service staff told him that the "Backpack Rabbit" site cloud host of the physical server disk damage, so the site can not operate normally, but also inevitable data loss.

This makes Cao Ming feel a little angry. "Backpack Rabbit" site using a grand cloud host has more than half a year, has been operating normally. This downtime, let him find that the original Sheng host publicity before the function was exaggerated.

Sheng Mainframe Downtime

Sheng is an independent subsidiary of the Shanda Network, opened for public testing in July 2011. Currently launched Cloud host, Cloud hard disk, cloud storage, cloud distribution, cloud monitoring and other products.

Cloud Host is a new generation of host rental services, it will CPU, storage and network bandwidth, such as the integration of three services, through a unified platform, on-demand access to services. It effectively solves the traditional host rental price high, uneven service products and other shortcomings.

uses the Grand Cloud host "the Backpack Rabbit" is a specially for the user to provide the on-line free production traveling itinerary the website, each day independent access IP in 30,000 or so. And the site suddenly crashed in Monday, so that the "backpack rabbit" operators feel angry.

This outrage can be seen in their release of Sina Weibo. August 6 afternoon, "Backpack Rabbit" released Weibo, on the one hand apologized to users, on the other hand, denounced the grand cloud.

"Backpack Rabbit" in a micro-blog words fiercely said: "Shanda this use of ordinary no backup of the virtual host to impersonate can data backup cloud host, is a complete fraud!" ”

In the face of the user's accusations, Sheng also did not shirk responsibility. The company also posted an apology letter on Sina Weibo as a response. Sheng Wuxi Computer Room A physical server disk damage, resulting in the loss of individual user data. Because the physical disk fails, the cloud host will inevitably cause data loss.

"Grand Cloud host propaganda exaggerated"

After the release of Sheng letter of apology, many Weibo netizens have questioned the Sheng host. Have Netizen Blunt, Sheng host like is 5 years ago already eliminated host virtualization technology. Some netizens also pointed out that physical disk damage is unavoidable, but the service providers know that it is difficult to avoid also caused accidental losses, the blame.

An industry personage who declined to be named said, generally speaking, the cloud hosts have multiple backup functions, basically there will be more than 3 copies of synchronous backup, or even off-site disaster-tolerant mechanism, there will be no data loss.

The person pointed out that in the local hard drive data backup from the technology can be completely done, but Sheng did not do the main service inside, in principle such products should not be called cloud computing, if not to the customer to explain the suspicion of fraud.

according to Sheng related technical personnel introduced, the main Sheng host divided into two categories, one is the use of cloud host local hard disk, a class of the use of grand cloud hard disk.

When using the cloud host local hard drive, Sheng will remind the user in the use of a reminder that the local hard drive will not have redundant data backup, while using the cloud hard disk can be more than backup to ensure the security of the data, but the need for additional fees. The problem is the use of local hard disk cloud host.

Cao Ming said that the reason for the choice of cloud host, or value "cloud" technology in the Internet application trend. Cloud hosts should be more secure and reliable than the most common virtual hosts on the market.

Cao Ming said that the most important feature of the cloud host is a multiple-point backup, which is not likely to affect data reading because of a physical disk failure. He said that the choice of Grand Cloud host is because of bullish on the brand's influence and strength, but now feel grand Cloud host propaganda a bit exaggerated.

Cooling Domestic Cloud computing

In recent years, with the rapid development of cloud computing, the concept of cloud host is also gradually hot up. Many traditional and next-generation data center cloud service providers are playing cloud concept for product sales, and strongly publicize the convenience of cloud services, reliable and safe. At present, a number of domestic companies have launched a cloud host services, in addition to Shanda, Alibaba (micro-blog), million nets, Tencent and so on are involved.

but security issues seem to have been accompanied by the evolution of cloud computing. Over the past few years, cloud services have been "interrupted" by companies such as Amazon, Google and Microsoft, the leading cloud-computing technology.

And this Sheng host incident actually also to the domestic cloud computing manufacturers sounded the alarm: as a cloud computing platform, in the product design should focus on data security issues, and anticipate the emergence of problems, and the user to focus on the description.

at the same time, for IT staff, choosing a cloud vendor means abandoning direct control over most of the IT infrastructure, so understanding the operating layer of the cloud and the security of the application layer is essential.
