Cloud Storage Development Drivers

Noda Consulting "Cloud Storage Market Research Report 2012" shows that the rapid development of cloud storage, mainly thanks to the improvement of network environment, mobile Internet and intelligent terminal development, application storage development, clustering technology and grid technology upgrades, storage virtualization technology and network storage security development.

Cloud Storage Development Drivers

Chart 1 cloud storage development drivers

The development of network broadband

Cloud storage is an internet-based storage application system, most of the user's PC is connected to cloud storage via ADSL, DDN and other broadband access devices, therefore, cloud storage users need to connect with the storage system using broadband network, only if the broadband network is sufficiently developed, can the users obtain enough data transmission bandwidth, To achieve large capacity data transmission, enjoy the convenience of cloud storage.

According to the China Internet Center (CNNIC), the 29th China Internet Development Statistics report shows that by the end of December 2011, China's internet users reached 513 million, the entire year added 55.8 million users. At the same time, China's national Development and Reform Commission, the Ministry of Finance, the Ministry of Science and Technology, the State Council SASAC and other departments have set up a working group, will jointly organize the "Broadband China" strategic research. In the strategic emerging industries and information industry two "Twelve-Five" planning, also mentioned the realization of "broadband China" strategy and the launch of "Broadband China" project. This has laid a solid user base for the development of cloud storage.

Development of mobile Internet and mobile intelligent terminals

Mobile internet has become a new growth point of domestic economic development. Wireless broadband networks, mobile terminals and the development of business applications and services are the basis for the development of mobile Internet. Domestic mobile terminals have made great breakthroughs, China's mobile terminal capacity has ranked the world's first, accounting for global mobile terminals total production of more than 50%. According to statistics from China's Internet Information Center, as of the end of June 2011, China's mobile internet users reached 318 million people, compared to the end of 2010 to increase 14.95 million people, mobile internet users in the overall proportion of netizens reached 65.5%.

It is precisely because of the development of mobile Internet, users in the wireless network to obtain more flexible services, cloud storage users will be PCs, mobile phones, mobile terminals and other devices to achieve data, documents, pictures, audio, video and other content of the centralized storage and information sharing.

Development of application Storage

Cloud storage is not just storage, it is more applications. Application storage is a storage device that integrates the function of application software, which not only has the function of data storage, but also has the function of application software, which can be regarded as a collection of servers and storage devices. The development of application storage technology can reduce the number of servers in cloud storage, reduce the cost of system construction, reduce the single point fault and performance bottleneck in the system, reduce the data transmission link, provide system performance and efficiency, and ensure the efficient and stable operation of the whole system.

The development of cluster technology, grid technology and Distributed File system

The cloud storage System is a collection of multiple storage devices, multiple applications, and multiple services, and any single point of storage system is not cloud storage.

Since it is composed of multiple storage devices, among different storage devices, it is necessary to realize the cooperative work among multiple storage devices through cluster technology, distributed File system and grid computing, so that multiple storage devices can provide the same service and provide greater and stronger data access performance. Without the existence of these technologies, cloud storage could not be truly implemented, and the so-called cloud storage could only be a single system, not a cloud-like structure.

Storage virtualization technology, storage networked management technology

The number of storage devices in cloud storage is large and distributed across many different geographies, how to implement logical volume management, storage virtualization management, and Multilink redundancy management between multiple devices of different vendors, different models, and even different types, such as FC storage and IP storage, will be a huge problem, Storage devices can be the performance bottleneck of the entire cloud storage system, the structure can not form a whole, but also bring late capacity and performance expansion difficult issues.

The development of network storage security

As the data transmission of cloud storage is transmitted through ordinary broadband, the security of data transmission must be ensured, and cloud storage can ensure that the protective devices in cloud storage are not accessed by unauthorized users through CDN content publishing system and data encryption technology. Each data backup and disaster-tolerant technology ensures that the data in the cloud storage is not lost, thus ensuring the security and stability of the cloud storage itself.
