The past few days saw a series of news people could not bear to dirge.
User crusade, media follow-up, wave after wave of fermentation, the last actually actually 'local storage devices' to the cusp.
The question is coming Is it possible to power down the local storage device and video loss?
Lei Feng network learned that leading to the local storage devices can not read the data for many reasons: for example, the quality of equipment failed, resulting in the work can not afford the strength of 24 x 7 and damage; suffered shock or impact, resulting in equipment in operation damage; lightning, interference Leading to equipment damage; frequent power-off, and time just may lead to disk head back to the data after the write-back, the normal homing, multiple occurrences will lead to abnormal head, leading to the normal reading and writing equipment.
Based on this, the industry has proposed a variety of solutions, such as a variety of storage devices to work together, or reduce the content to reduce the pressure on the storage side, but from the root point of view, these methods solve the problem.Thus, from a purely technical point of view, Is there a more secure and efficient way to replace the original storage?
'Cloud Storage' is now recognized as the best choice for businesses in the industry.

In recent years, with the projects such as 'Wisdom Early Childhood Education,' "City Brain," and "Chef Mingcai" constantly landing, a huge 600 billion yuan cake was launched around the camera.
Faced with these vast amounts of data brought by the Skynet cameras, relevant departments hope that the stored data will be linked and shared with each other, for example, in the tracking of criminals, many kinds of stored data such as public security, traffic and civil industries can be shared.
Obviously, the traditional storage methods can not calmly deal with.
'Cloud storage can analyze in-depth data, handle it effectively, share it quickly, and provide hot backup and disaster recovery solutions in the same city. As a result, the massive surveillance video can be permanently stored and ready for use. This is an inevitable choice for the security industry. 'Aliyun Liu Qiang, general manager of multi-media business to Lei Feng network said.
Compared with the traditional storage methods, cloud storage really has obvious advantages, which increase storage efficiency, through the distributed technology to solve the waste of storage space, you can automatically re-allocate data; improve the utilization of storage space, with load balancing, Fault redundancy function; the most important thing is that it can achieve economies of scale and elasticity to expand, reduce operating costs and avoid wasting resources.
According to Lei Feng network, now includes world-class security monitoring of Haikang fluorite, Dahua Le Orange, Lenovo Jiabao, consumer electronics companies have chosen to PB-class cloud video Surveillance data stored in Ali cloud.
'At present, most security companies in China are using our cloud services,' adds Liu Qiang. 'Not only cloud storage, Ali Group in the' brain of the city ', mobile phone Taobao Amoy Amoy, group security, real certification and other machines Visual technical reserves, but also to help Alibaba security industry customers from the equipment sales enterprise transformation into a big data enterprise.

At the same time, he also admitted that before communicating with his client, he found that there are still some obstacles to the application of cloud storage technology in the field of security. The biggest obstacle comes from the camera's high bandwidth network.
In response, Liu Qiang Lei Feng revealed to the network, compared to other cloud service providers, Alibaba cloud in the original on the basis of further updates and upgrades, and now Alibaba Cloud storage program outstanding genes can be summarized as four points:
Cost-effective Through the use of low-cost, low-profile cloud server to ensure business continuity, with the use of flexible scalable services in the business peak automatically increase the number of cloud servers to protect the normal operation of the business.This approach can effectively reduce the computational costs, making the overall cost The structure is more reasonable; In addition, Liu Qiang said that no matter how much traffic, upload traffic all free, very suitable for mass upload, a small amount of downloaded video surveillance scenes to minimize video surveillance bandwidth costs.
High reliability. Aliyun cloud storage object has a very low write failure rate, can effectively avoid the video file slicing failure led to the video watching Caton and other non-smooth phenomenon; Aliyun's object storage service OSS can provide massive file storage services, and Can expand capabilities almost unlimited, do not worry about storage will become the bottleneck of business growth.
Mass video file storage capabilities. Aliyun's Object Storage (OSS) can provide massive file storage with 11 data reliability at the same time, and provide hot backup and remote disaster recovery solutions in the same city, making the monitoring video of the mass storage permanent and readily available.
High security. In general, data security protection mainly from four aspects, data leakage protection, data protection, data management, data encryption.Data leakage protection, as the name suggests is to prevent data leakage.For example, Aliyun launched cloud shield WAF, is to prevent hacking Get business data.
Another point is that the video surveillance data on the cloud, you can seamlessly connect with Aliyun AI: real-time video analysis; when the video file is uploaded to the cloud, a large number of video files account for a large amount of storage space due to cost and Other factors to consider, the general storage of video data regularly deleted after a certain period of time.
Liu Qiang frankly, through cloud storage, security will be different. In the future, more and more industries in the deployment of security video surveillance system, will introduce the concept of "cloud" and technology.

If the large-scale application of cloud storage is an innovation in the security storage market, breaking the traditional storage just stay in the hardware device simple overlay applications, then many service providers, the user how to pick?
According to Liu Qiang, firstly, from the perspective of input costs, a complete set of infrastructure needs to be supported behind cloud storage. Large amounts of data storage, computing and daily operation and maintenance are not easily managed.
Second, the business model of cloud storage services, the focus is not 'storage', but in the 'service' is stored in the cloud information itself is a static byte, does not have any value, only through some kind of service context To give meaning, to show its value.
From these two points of view, large companies obviously have inherent advantages in resources, experience and technology.
