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 ...

So, we used to see the C disk, D disk, and so on, often corresponds to the first partition, the second partition. Below Linux, these partitions appear in the form of devices, such as/dev/hda1/dev/hda2 ...

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 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 ...

Of all the recent concerns about cloud computing, storage is more viewed as an underlying platform. Today, many cloud computing offers only a collection of CPU cores, quantitative memory allocations, low speed storage, or some Internet-facing IP technology. 　　 　　Recently, there have been interesting advanced technologies related to cloud computing and storage, especially the use of Web Access, which makes access storage no longer restricted to device files or NFS mount points. The "Enterprise-class features" of typical data storage and management are constantly being pushed into new IT architecture innovations. Storage schema ...

[Guide] Typical data storage and management of the "Enterprise-class features" In the IT architecture innovation constantly pushed to new.   Storage architects are aware that these features are important for critical business and production applications, but the current cloud computing lacks these features. Of all the recent concerns about cloud computing, storage is more viewed as an underlying platform. Today, many cloud computing offers only a collection of CPU cores, quantitative memory allocations, low speed storage, or some Internet-facing IP technology. Recently, there have been interesting and cloud computing ...

VMware suddenly released its first open source Paas--cloudfoundry this April. In the months since its release, the author has been concerned about its evolution and benefited from its architectural design, and felt the need to write to share it with you. This article will be divided into two parts: the first part mainly introduces the architecture design of Cloudfoundry, from the module that it contains, to the information flow of each part, how the modules coordinate and cooperate; The second part will be based on the first part, how to use Clou in your data center ...

Today, we are frequently exposed to the term "large data". But the industry still lacks a standardized definition of what big data is. So what does big data mean to the data storage infrastructure? The definition of large data by the Enterprise Strategy Group (ESG) is "a dataset that is larger than the conventional processing capacity boundary, which makes you have to resort to unconventional means." "In simple terms, we can use the word big data on any data collection that breaks through the traditional it processing to support the day-to-day operational capabilities of the business." These boundaries may appear in the following ...
