Cloud storage Global outbreak has a profound impact on traditional markets

Cloud storage has a direct or indirect relationship with the IT Hot word "big data", which has been booming in recent years. The explosive growth of structured, especially unstructured data, not only makes businesses feel the pressure of "data storage", but it also prompts them to start thinking about how to grab opportunities in large data. Cloud storage Global outbreak, a profound impact on traditional markets, in the future development process, cloud storage development will still be subject to certain constraints.

Cloud storage Global outbreak, profound impact on traditional markets

With the rapid development of cloud storage, the challenge of massive storage is becoming more and more serious. Exploding volumes of data are hitting their storage systems like a tidal wave. At the same time, the data security requirements of various industries are increasingly high. As a new technology concept, cloud storage is changing the way of providing and using traditional storage, and also has a far-reaching impact on storage industry.

Cloud storage is becoming one of the trends in the global storage industry, and the range of applications for cloud storage products is growing and the customer base is more fragmented. In view of the diverse needs of industry applications, Innovation division believes that users in all industries only apply innovative flexible system architecture to meet the dynamic growth of storage needs. In combination with its innovative flexible cloud storage system architecture, and using distributed storage technology and unified monitoring and management platform of large-scale distributed cloud storage file system, will help various industries to achieve massive data storage, disaster recovery and backup of the new model. For applications with large data volume and high concurrent access, a large distributed cloud storage System is a file-sharing storage platform that can provide massive storage space and support flexible and high performance access.

Unlike traditional storage systems, distributed cloud storage systems are designed specifically for the characteristics of large-scale distributed data processing and multimedia applications. A distributed cloud storage system is clustered by metadata server clusters and storage servers and accessed by many clients. The metadata server is used to store all the metadata in the file system, including the namespaces, access control information, storage location, and so on, while the storage server cluster is used to store the user's file data. When the client accesses the system, it first accesses the metadata server node, obtains the information of the storage server node that will interact with it, and then directly accesses the storage server nodes to complete the data access, which effectively prevents the metadata server from overloading and greatly improves the system efficiency.

Comparison of advantages between cloud storage system and traditional storage system

Cloud storage provides storage services that store local data over the network in online storage provided by the storage Service provider (SSP). Users who need storage services no longer need to set up their own data centers, simply request storage services from the SSP, thereby avoiding duplication of storage platforms and saving expensive hardware and software infrastructure investments. "Cloud computing will expand and mature, with many new public cloud hotspots, private cloud services, cloud applications and services linking the public cloud to the private cloud," said the top ten 2010 forecasts for the IT and telecoms industry released by the Internet Data Center (IDC) in December 2009.

Compared to traditional storage systems, cloud storage systems have the following differences: First, from the functional requirements, the cloud storage system for a variety of network online storage services, while the traditional storage systems for such as high-performance computing, transaction processing applications; second, from the performance requirements, cloud storage services first need to consider the data security, reliability, efficiency and other indicators, and because of the user scale, wide range of services, complex and changeable network environment, the realization of high-quality cloud storage services will face greater technical challenges; third, from data management, cloud storage systems provide not only traditional file access similar to POSIX, It also needs to be able to support the massive data management and provide the public service support function, in order to facilitate the cloud storage system backstage data maintenance.

Data storage layer: The cloud storage System provides a variety of different storage services, the data of various services are stored in the cloud storage system, forming a mass data pool. From the view of the organization of most of the network service background data, the traditional data organization based on single server is difficult to meet the throughput performance and storage capacity demand under the multiuser condition of WAN, and the data organization based on Peer-to-peer architecture needs large number of nodes and complex coding algorithm to guarantee the data reliability. In comparison, the data organization method based on multiple storage servers can better meet the needs of online storage service, and when users are larger, the Distributed data Center can provide better service quality for users in different geographical regions.

The data storage layer of cloud storage will interconnect different types of storage devices, realize the unified management of massive data, and realize the centralized management of storage devices, state monitoring and capacity dynamic expansion, in essence, it is a service-oriented distributed storage system.

Data management layer: The Data management layer in the cloud Storage System architecture provides a unified view of public administration between different services for the upper tier. Through the design of a unified user management, security management, copy management and policy management, such as public data management functions, the underlying storage and upper application seamless convergence, to achieve the cooperative work between the multiple storage devices to provide a wide range of services to better performance.

Data Service layer: The Data Service layer is a flexible and direct user-oriented part of the cloud storage platform. According to user needs, can develop different application interface, provide corresponding services. such as data storage services, space leasing services, public resource services, multi-user data sharing services, data backup services.

Cloud computing development barriers: Government and legal intervention

Security and compliance issues remain a major impediment to cloud computing. Recently, a survey from Lieberman Software security company shows that nearly 48% of the teams are afraid of government and legal intervention before putting sensitive data into the cloud. The Lieberman Software security company released a survey of more than 300 IT professionals, which showed that companies were hesitant to move sensitive data to the cloud, mainly because of concerns about government and legal intervention. Government regulation, cloud legislation and data security are becoming important factors in preventing business development.

A survey from the Cloud Security Alliance found that 88% of respondents feared their sensitive data in the cloud could be lost or damaged. As a result, more than 86% do not store sensitive business data in the cloud, and even 51% of people do not trust cloud storage at all, and they do not store any personal data. In fact, it is difficult for organizations to ensure that data stored in the cloud is fully secure, and that their data protection policies can be passed through security audits or government regulatory inspections. While it experts say there are many reasons why it is difficult for companies to store data in the cloud, the key issues are government regulation, cloud legislation and data security. IT managers worry that if data is migrated to the cloud, they are at risk because they do not know if the data will be properly protected, and this could affect their work and business.

But another issue is about cloud legislation, and IT managers don't want the government to pry into their corporate data. If the government or the official The agency wants to see data from a company deployed in the cloud, and the cloud service providers involved are legally obligated to provide access. This means that there is only very limited privacy in the cloud environment. The report adds that IT managers are well aware that hiding data within their own private networks is an easy task.

Trend technology also conducted a similar cloud security study, which found that more than half of respondents thought data security was the biggest cloud "inhibitor". Another study from Symantec found that businesses of all sizes were plagued by public cloud applications, and that rogue cloud backups, complex recovery processes, and inefficient cloud-storage programs could damage data.
