With the maturity of cloud storage technology, many Internet companies and operators have launched cloud leasing services. In the civilian general market, storage free services for individual users are no longer new. At the same time, with the storage of free services, many manufacturers with general security products, throwing surveillance camera rentals, and even free service operation mode, once again stimulated the fierce security of the civilian security market.
First, cloud storage free of charge is mainly distributed in the public domain of the Internet.
1, free cloud storage mainly appears in the Internet public domain
From the market analysis, it is not difficult to see that cloud storage free of charge mainly appears in the Internet public domain. These services are not specifically divided for users, and can be distributed in various industries, with a large number of individuals and low cost per user. Security manufacturers provide a common front-end for these users, but also have the characteristics of low cost, single function, easy to use, and cute appearance, such as Haikang's fluorite.
On the basic storage platform, the cloud storage free service is provided to individual users, generally the well-known Internet service vendors in the industry or the vendors with the basic capabilities of cloud storage services, such as Alibaba and Qiu Niu. These companies are relatively large. Infrastructure resources such as storage servers can build a large and unified storage platform. While meeting their own business needs, they still have space surplus to lease, or provide free to enterprises and individual users.
2. The "free" status of cloud storage in the public domain of the Internet is more difficult to appear in the security field.
Why are these Internet companies or IT infrastructure service providers capable of providing free services to the civilian market? There are two main reasons: First, these companies have other profit models, and their own business is closely integrated with users. By providing storage freely, you can “circulate†more users, media resources and traffic for other businesses. And then obtain the corresponding commercial benefits. Secondly, as mentioned earlier, these enterprises have the ability to set up a professional and massive cloud storage system. In most cases, the basic IT system still has a surplus while meeting its own business needs, and leases this surplus to enterprise users. To make full use of the resources of the enterprise, it is a good win-win model.
But in the field of professional security, it is almost impossible for cloud storage to have all the free services. For mainstream security vendors, the industry-oriented users are mainly public, inspection, law, division, government, enterprises, etc. These users will generally build professional security cloud storage in the construction of safe city, park security or cloud video conference. Or use a dedicated cloud storage service. Moreover, for the sake of data security and system performance, the system is generally set up in a private network. In most cases, cloud storage and the Internet are physically separated, and can only be dedicated to users; Under the request, for security manufacturers, except for project construction and equipment costs, it is difficult to have other profit methods at present, so it is unrealistic to completely “freeâ€, but with the development of technology, the cloud storage cost “big diving†is It may happen.
Second, the public domain cloud storage free meaning positive but hidden dangers
The positive significance of cloud storage free is mentioned in the above. For Internet companies or IT infrastructure service providers, providing cloud storage free or leased services can “circle†more users, media resources and traffic. This will benefit other profitable businesses of the company. For individual users or some enterprises, self-built cloud storage is obviously unrealistic because the construction and operation costs are too high, and the lease or free way is more acceptable. However, there are certain hidden dangers in cloud storage free of charge, mainly in terms of data security and service quality assurance:
1. Storage security is tested
Various star pornographic leaks, security incidents, etc., have made the data security and reliability of Internet-based data storage methods questionable. Excessive openness and sharing have made it difficult to guarantee the security of the Internet itself. The professional security cloud storage system physically isolated from the Internet is quite different.
2. Security storage is professional
The Internet cloud storage service has the characteristics of a large number of users, a large number of users, a wide variety of systems, a system deployment, and a complicated data transmission link. Once data loss occurs, it is difficult for operators to assume responsibility; security cloud storage is generally only for user-specific, total business Classes are relatively simple and unambiguous, and the deployment and runtime environment is not as complex as on the Internet. In the event of system anomalies or data loss, vendors can provide services in the first place.
3. Cloud storage has different impact on individuals, enterprise users and industry users.
For individuals and enterprises, documents with strong privacy and core confidential information are generally stored in local disks such as mobile phones, computers, and enterprise-built servers; some entertainment, learning, and general data information or insignificant files. The data will be stored in the cloud, free cloud storage will bring more use of this part, users will feel the application more convenient.
For professional security industry users, it is not appropriate to choose free cloud storage. The main reasons are the following three points: In addition to the security and service quality mentioned above:
First, the security industry has high requirements for code stream. The code stream transmitted by the monitoring front-end is generally 1080P or even 4K, and the required bandwidth is very large. Generally, a special transmission path is required, and the enterprise specially lays out a fiber to the core network for storage. Used for transmission is not realistic.
Second, the data transmission environment of the Internet is relatively complicated. The requirements for high-rate video data transmission in professional security cannot be well matched. In order to adapt to different usage scenarios of large users, broadband adaptive functions are generally adopted, that is, when bandwidth conditions are poor. In order to ensure the smooth transmission of video, it will properly compress and reduce the video quality, which is difficult to accept in the professional security industry. The security monitoring system must ensure the transmission quality of video images and control response speed.
Third, with higher security and reliability, the security industry data generally has extremely high confidentiality and security requirements, and also has its own data control management strategy, which is not suitable for the Internet with large variables and high openness.
Third, the difference between security cloud storage and Internet cloud storage
As the scale of construction of safe cities continues to expand, the requirements for storage space and storage performance are increasingly urgent. In this context, mainstream security vendors in the industry have launched security cloud storage to meet the massive video storage needs of the era of big data. Compared with Internet cloud storage, in addition to storage virtualization, massive storage space, and convenient expansion. Security cloud storage mainly has the following characteristics:
1. Security cloud storage features
(1) High speed access
Security cloud storage needs to face high concurrency and high bit rate data storage requirements. It is faced with high-definition, high-rate video storage. The storage system needs to provide high-performance data throughput. Security cloud storage adopts data discrete storage mechanism. Each monitoring point is recorded in blocks and concurrently stored in different storage nodes. When reading, these storage nodes will provide concurrent services, avoiding single devices. The bottleneck of reading is several times faster than traditional storage, which can meet the needs of massive concurrent storage and reading in large security projects such as Safe City.
(2) Security integration
In practical applications, security cloud storage is closely integrated with various business systems, such as image detection and video intelligent analysis, directly integrating video recording management, video playback and media forwarding services in the storage array, making full use of cloud storage high reliability hardware. And the network. At the same time, Security Cloud Storage provides a standard sdk interface, which makes it easy for customers to conduct secondary development of the security business system and integrate more closely with the security business system.
(3) Code stream direct storage
Due to the location of its use, the user's fixedness, and the user's requirements for efficient video applications, security cloud storage generally uses code stream direct storage, which simplifies system architecture, reduces fault points, and improves system deployment efficiency and operation and maintenance costs. And cloud storage is generally set up in a private network, which can better guarantee the quality of video.
