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 ...

Plasma realizes the schematic/reduction framework in the computer cluster. It has its own distributed file system, PLASMAFS for transaction processing (ACID), reliable, fast, and it provides a complete set of file operations. Plasmafs can be via RPC protocol, or via NFS (i.e., it can be mounted). Plasma 0.5 This is the first beta version of the project. The code is fairly stable, fast, and ready for wider testing. Almost all the Http://www.aliyun.com/zix ...

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 ...

Cloudstack is the Ctrix company's flagship product in the IaaS market, providing flexible deployment and management capabilities for cloud computing resources. In the first half of this year Ctrix will contribute its source code to Apache, Cloudstack become an open source project. The documentation for such open source projects has been perfected, but as a novice in the cloud computing field tries to install and deploy it, there are still more or less challenges. This is the purpose of this article, that is, to faithfully record and try to sum up some of the problems in this process, with everyone ...

Cloudstack is an open-source, highly available and scalable cloud computing platform that supports the management of most mainstream virtual machine managers, such as KVM and XEN. There are two types of storage in Cloudstack: Primary storage provides disk volumes for virtual machine instances, and level two storage provides templates for virtual machine instances to install mirrored files for systems and disk snapshots of virtual machine instances. Both types of storage support network-attached storage (NAS). Figure 0. Cloudstack architecture This article we will be a Linux host ...

High-performance Computing (highperformancecomputing) is a branch of computer science, which mainly refers to the research and development of high-performance computers from the aspects of architecture, parallel algorithms and software development. With the rapid development of computer technology, the computational speed of high-performance computers has been increasing, and its standards are also changing. High-performance computing is simply the completion of certain types of technical workloads on 16 or more servers. It doesn't matter if the number is 8, 12 or 16 servers. Under our definition I ...
