&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; This chapter describes the open source storage System MFS Linux, which was developed by Poles. The MFS file system enables RAID functionality, not only to save storage costs, but also to professional storage systems and, more importantly, to achieve online scaling. The reader must understand that MFS is a semi distributed ...

This article describes the implementation of large pages in the Linux operating system. From the memory layer, file system layer, LIBHUGETLBFS, and how users use the big page and so on in these aspects are analyzed and introduced. Gives you a better understanding of the implementation of the big page in the kernel and http://www.aliyun.com/zixun/aggregation/6579.html "> User usage." Large pages are primarily designed to provide an optimized way for users to use large amounts of memory. It passes through the hardware ...

As a new computing model, cloud computing is still in its early stage of development. Many different sizes and types of providers provide their own cloud-based application services. This paper introduces three typical cloud computing implementations, such as Amazon, Google and IBM, to analyze the specific technology behind "cloud computing", to analyze the current cloud computing platform construction method and the application construction way. Chen Zheng People's Republic of Tsinghua University 1:google cloud computing platform and application Google's cloud computing technology is actually for go ...

MapReduce: Simple data processing on large cluster

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 ...

IBM launched the Blue Cloud computing platform on November 15, 2007, offering customers the cloud computing platform to buy. It includes a range of cloud computing products that allow computing to run in a network-like environment by architecting a distributed, globally accessible resource structure that is not limited to local machines or remote server farms (i.e., server clusters). Through the IBM technical White Paper, we can glimpse the inner structure of the blue cloud computing platform. The "Blue Cloud" is built on the expertise of IBM's large-scale computing field, based on IBM software, System technology ...

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 ...

Hadoop is a highly scalable, large data application that can handle dozens of TB to hundreds of PB of data through fewer than thousands of interconnected servers. This reference design realizes a single cabinet of Hadoop cluster design, if users need more than one cabinet of Hadoop cluster, can expand the design of the number of servers and network bandwidth easy to achieve expansion. Hadoop solution The features of Hadoop design Hadoop is a low-cost and highly scalable large data place ...

Part of Hadoop is a Java implementation of Google's MapReduce. 　　MapReduce is a simplified distributed programming model that allows programs to be distributed automatically to a large cluster of ordinary machines. Hadoop is mainly composed of HDFs, MapReduce and HBase. The concrete composition is as follows: the composition of Hadoop figure 1. The Hadoop HDFs is the Open-source implementation of Google's GFS storage system, the main ...

So whether you're an environmental deployment engineer or an automated scripting developer, reading this article will help you if you want to develop a solution for an automated environment deployment. The author of the project is IBM based on a large and complex cloud computing strategy products, by providing users with a visual network platform interface, fully and quickly to help customers deploy a high degree of flexibility of the cloud solution. In the process of project development and on-line, the average release of a new installation version every four hours, from software testing to production release needs more than four environment support, especially in the Demo ...
