Low-cost public cloud service is reliable?

Today, information technology has become popular in all fields of cloud computing technology. We have also been able to see many products derived from the concept of cloud computing, such as a wide range of cloud storage servers and so on, Come a lot of convenience. In the Internet industry, similar public cloud services have been gradually promoted.

Compared with the traditional self-built IT information platform for enterprises, public cloud services are cheaper and have long been regarded as a shortcut to the development of enterprise IT. But is it really trickle child? There are still many companies questioned its existence.

Not so long ago, an article in the IT Times left a very serious problem to the user. Cheap public cloud service fly it? Which mentioned a user rented more than 20 cloud server, appeared in the past half a year all the machines all power outages, 2 multiple hard drives suddenly read only, 3 times a sudden hard drive IO Full, 1 customer service without direct reboot, more than 10 operation and maintenance does not respond. When dealing with these issues, the user also accused customer service calls have never been connected within 5 minutes, and finally the user gave up the cloud service, ready to move out of all machines.

This information got some user responses using the cloud service, and also claimed to have encountered the same problem. One of the game company's CEOs disclosed that hundreds of thousands have been invested in a year, but there are also hundreds of thousands of losses caused by cloud server downtime, directly driving up costs.

In the traditional business model, companies want to "Internet" to deploy Internet-related business, the need for a very long period, including the pre-purchase of equipment, installation and commissioning, test run, the latter part of the equipment maintenance, updating, etc., Cycle or financial aspects require a small overhead, so companies will naturally have to find a simple, convenient and quick solution ideas. Under such circumstances, public cloud services transformed from traditional hosting and space leasing businesses have become the priority of the enterprise.

At present, the public cloud service relies mainly on IDC hosting and space rental services. The original hosting and renting servers are limited by bandwidth, system platform, hardware specifications and content, which make it difficult to meet diversified needs of users. Meanwhile, Brought a lot of legal risks to service providers. However, with the advancement of virtualization technology, the utilization rate of data center equipment has risen dramatically. Meanwhile, the mechanisms for Internet operation and filing have been gradually improved. Some resources originally manipulated by service providers have gradually been decentralized to users. As a result, Public cloud service.

In the public cloud service, users can choose different hardware specifications, storage space and exit bandwidth according to their needs when setting up the platform. The operating system and database can also be customized as needed. After the user determines the hardware specifications and the system, the user directly deploys the service This is actually "does not exist" in the host, it will be able to quickly complete all the work, so public cloud in front of the user is very attractive.

It is noteworthy that the current public cloud service is still in its infancy, and public cloud services for all customers and almost all types of Internet services, the overall reliability of the virtual machine environment in such an environment has not been fully verified, it is difficult Avoid this or that problem. For now, as long as users choose public cloud services, there is a certain probability to face such a problem. Unless there is a relatively reasonable and complete virtual machine load management mechanism.

Users complain about suppliers, but suppliers can not easily solve all the problems. In addition to gaining experience, as time turns all the problems into experience, there are no other quick solutions to the problem. So now for the user, the use of public cloud really need to take some risks, but for the time being there is no good solution.

At this stage, the self-built platform is relatively reliable, but the period is long and the cost is high. The public cloud service helps to reduce the cost, but the reliability is not very good from the user's feedback, and the user needs to bear certain risks. How to choose seems to be a problem, but for the user, public cloud service and the traditional self-built platform service is not the opposite relationship, not the other.
