File Storage Server Architecture

The storage system is the core infrastructure of the IT environment in the data center, and it is the final carrier of data access. Storage in cloud computing, virtualization, large data and other related technologies have undergone a huge change, block storage, file storage, object storage support for a variety of data types of reading; Centralized storage is no longer the mainstream storage architecture of data center, storage access of massive data, need extensibility, 　　Highly scalable distributed storage architecture. In the new IT development process, data center construction has entered the era of cloud computing, enterprise IT storage environment can not be simple ...

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...

Original: http://hadoop.apache.org/core/docs/current/hdfs_design.html Introduction Hadoop Distributed File System (HDFS) is designed to be suitable for running in general hardware (commodity hardware) on the Distributed File system. It has a lot in common with existing Distributed file systems. At the same time, it is obvious that it differs from other distributed file systems. HDFs is a highly fault tolerant system suitable for deployment in cheap ...

Aiming at the problem of low storage efficiency of small and medium files in cloud storage system based on HDFS, the paper designs a scheme of small and medium file in cloud storage System with sequential file technology. Using multidimensional attribute decision theory, the scheme by combining the indexes of reading file time, merging file time and saving memory space, we get the best way of merging small files, and can achieve the balance between the time consumed and the memory space saved; The system load forecasting algorithm based on AHP is designed to predict the system load. To achieve the goal of load balancing, the use of sequential file technology to merge small files. Experimental results show that ...

Aiming at the problem of data security in cloud storage system and application process, this paper proposes a cloud storage security architecture for distributed storage. This architecture adopts information diffusion method, decentralized storage management, data bootstrap recovery and so on, and realizes the data security storage management and transmission of the application system in the cloud storage. The simulation side test shows that the architecture improves the overall performance of the system while guaranteeing the high security of the data. With the development of information technology, people's requirement of computing ability is also increasing, as the storage technology which is inseparable with computation, it is also accompanied with the upgrade of computing model, from the most ...

For a large enterprise, small and medium-sized enterprises, or individual users, what is the consensus that can not afford it? There are a number of answers, but one answer is shared by most people, and it is data loss. When the importance of information is more and more related to the survival of enterprises, data protection is more and more important. So, a variety of disaster-tolerant systems, backup, archiving programs have taken the stage, trying to make everyone's information security impregnable. However, in the implementation process, whether the implementation of costs or technology, so many enterprises to shrink. Now, many enterprises, especially individual users, in the data protection ...

Sharing photos is one of the most popular features of Http://www.aliyun.com/zixun/aggregation/1560.html's >facebook. So far, users have uploaded more than 1.5 billion photos, making Facebook the largest photo-sharing site. For each uploaded photo, Facebook generates and stores four images of different sizes, converting to a total of 6 billion photos with a total capacity of over 1.5PB. Currently 2.2 million new photos per week ...

The concept of cloud computing began to penetrate more and more into the field of security in the past two years. The breakthrough application of cloud storage is particularly noticeable. 　　This article will mainly on the application of cloud storage in the field of security analysis. The popularization of network technology, making the network sharing of video resources become more and more urgent demand of many industries, the existing distributed video resources are moving towards the direction of large concentration; Safe city, Intelligent transportation and other major industries market through the point, line, face of intensive coverage, every moment are adding new video sources; 720p,1080p, 4 K, higher video resolution means greater ...

The concept of cloud storage began with a service offered by Amazon (S3), along with its cloud computing products (EC2). Behind Amazon's S3 service, it manages a number of commodity hardware devices and bundles the appropriate software to create a storage pool. Emerging web companies have embraced the product and proposed the term cloud storage and its corresponding concepts. Cloud storage is a schema, not a service. Whether you own or lease this architecture is a secondary issue. Fundamentally, by adding standard hardware and sharing standard networks (public Internet ...).

(i): Market Overview China's cloud storage market dynamics China's current corporate cio/cto is sceptical about the public cloud, at present, about 70% of enterprises are unwilling to put the data in the enterprise on the public cloud, mainly from the security point of view, but the data for the enterprise business investment more and more,     Will force enterprises, especially for data security is very high financial industry also gradually towards the public cloud. Domestic ...
