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 ...

With the rapid development of IT technology, the virtualization technology is becoming more and more mature, and more and more enterprises are starting to deploy the virtualization platform because of its obvious advantages in the capital saving and it efficiency. The number of LPARs in a virtualized platform increases as the business grows, and rapid deployment of the operating system becomes a must. The general deployment of an AIX operating system takes about 50 minutes and requires more human involvement, and takes up a lot of time and effort from the administrator. To improve the deployment speed and flexibility of the system, this article will focus on the existing IBM power V ...

Fedora Linux allows you to install the operating system via the http://www.aliyun.com/zixun/aggregation/18415.html > network connection using the Kickstart server. Faster than using CDs and can be automated. The process is fairly simple: Connect a new server (client) to a preloaded installation file server (installation service side) to the same network. Boot on the client with a dedicated boot CD. Choose the preferred installation method (FT ...).

This paper is an excerpt from the book "The Authoritative Guide to Hadoop", published by Tsinghua University Press, which is the author of Tom White, the School of Data Science and engineering, East China Normal University. This book begins with the origins of Hadoop, and integrates theory and practice to introduce Hadoop as an ideal tool for high-performance processing of massive datasets. The book consists of 16 chapters, 3 appendices, covering topics including: Haddoop;mapreduce;hadoop Distributed file system; Hadoop I/O, MapReduce application Open ...

If you want to create a private cloud, you need to use management software to create a virtual pool of computing resources, provide access to end users, and deal with security, resource allocation, tracking and billing issues. We tested five mainstream private cloud management products: Novell's Cloud Manager,eucalyptus Enterprise Edition, Opennebula,citrix Lab Manager and cloud.com cloudstack ...

This chapter is a high-level topic in the installation manual. In general, we use U disk or CD-ROM to boot the installer. However, if you encounter a computer without an optical drive or USB device interface (or if you are using a non-standard USB device and optical drive), you can use the PXE installation method. In addition, PXE installation is an efficient way to work when a large number of computers need to install the system at the same time. 4.1 What is PXE strictly speaking, PXE is not an installation, but a way to boot. The prerequisites for PXE installation are the computers to be installed ...

Preface Having been in contact with Hadoop for two years, I encountered a lot of problems during that time, including both classic NameNode and JobTracker memory overflow problems, as well as HDFS small file storage issues, both task scheduling and MapReduce performance issues. Some problems are Hadoop's own shortcomings (short board), while others are not used properly. In the process of solving the problem, sometimes need to turn the source code, and sometimes to colleagues, friends, encounter ...

In this article, the author describes some of the basic concepts of shared services, describing the sample shared services plug-in in the plug-in Development Kit (PDK), which provides a good starting point for creating a new shared service. The author will also describe how to convert the sample shared services to functional general media sharing services, a generic service repository in which client deployments can obtain common files. Shared Services is a predefined pattern that is deployed in the cloud and deployed by multiple client applications in the cloud (such as virtual applications, Http://www.aliyun ...).

This is the purpose of this article, that is, to faithfully record and try to sum up some of the problems in this process, and share with you. With Amazon's success in the private cloud of public cloud and VMware, companies are taking their own steps in the cloud era, which they want to maintain at a relatively low cost while gaining powerful functionality in their computing resources (host, network, storage) virtualization. This is the driver of IaaS suppliers. IaaS provides automated management of resources. For example, using interfaces, scripts, and even Web serv ...
