Storage Server Open Source

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 ...

OpenStack Object Storage (Swift) is one of the subprojects of the OpenStack Open source Cloud project, known as Object storage, which provides powerful extensibility, redundancy, and durability. This article will describe swift in terms of architecture, principles, and practices. Swift is not a file system or a real-time data storage system, which is called object storage and is used for long-term storage of permanent types of static data that can be retrieved, adjusted, and updated as necessary. Examples of data types that are best suited for storage are virtual machine mirroring, picture saving ...

While the term cloud computing is not new (Amazon started providing its cloud services in 2006), it has been a real buzzword since 2008, when cloud services from Google and Amazon gained public attention. Google's app engine enables users to build and host Web applications on Google's infrastructure. Together with S3,amazonweb services also includes elastic Cloud Compute (EC2) calculation ...

Open source Hotspot Inventory 1984, Richard Stallman launched GNU and Free Softwarefoundation, which has been open source for more than 28 years. From the bottom of the operating system to advanced desktop applications, there are open source footprint. Linux, which is especially open source operating system, is a controversial issue and is subject to many commercial attacks. 　　Many people like to put open source and business together, to accuse Open source is how "irregular", "energy consumption", "instability" and so on, especially Microsoft. Talk about ...

At the end of March, Red Hat released its fiscal year 2012 and full-year earnings for the year ended February 29, 2012. Red Hat's total revenue for fiscal year 2012 was 1.13 billion dollars, according to earnings reports. At this point, Red Hat has become the first IT industry revenue more than 1 billion dollars of open source solution vendors. How does Red Hat do three years 1 billion? What are the new trends in red Hat in the past 2012 years? What are the plans for the future? Core Linux business and virtualization this May, the Red Hat Enterprise Linux has been unveiled for 10 years. May 2002, Red Hat launched the first enterprise Linux ...

A, virtualization virtualization refers to the ability to simulate multiple virtual machines on the same physical machine. Each virtual machine has a separate processor, memory, hard disk, and network interface logically. The use of virtualization technology can improve the utilization of hardware resources, so that multiple applications can run on the same physical machine with each other isolated operating environment. There are also different levels of virtualization, such as virtualization at the hardware level and virtualization at the software level. Hardware virtualization refers to the simulation of hardware to obtain a similar to the real computer environment, you can run a complete operating system. In the hardware virtual ...

Absrtact: 7 years ago, one of the ideas, the success of today's popular social network and microblogging service--twitter. Twitter now has more than 200 million monthly active subscribers, and about 500 million tweets are sent every day. 　　Behind all this is the support of a large number of open source projects. Twitter, known as the "Internet SMS Service", allows users to post no more than 140 tweets, the idea from Twitter's co-founder, Jack Dorsey, which was dubbed "the dumbest Ever" by analysts 7 years ago ...

Server virtualization is a technology that consolidates x86 servers and improves efficiency. Any enterprise with more than one physical server should have its own virtualization strategy for deploying a highly virtualized x86 server platform. Currently, enterprise users have embraced virtualization and are beginning to prioritize deployment scenarios. More than half of the x86 workloads have been virtualized, with Gartner predicting that by 2016 China's 70% X86 Enterprise Servers will be virtualized. Avoid vendor abduction deploy multiple management processes ...

Disk storage is like a closet, never enough, especially in the big data age. "Big data" means that more data is needed than a traditional storage platform. 　　The choice of storage services for large data is not entirely traceable. What is big data first, we need to be clear about the difference between large data and other types of data and the technology associated with it (primarily analytical applications). Large data itself means very much data that needs to be processed using standard storage techniques. Large data may consist of terabytes of (or even petabytes) of information, including structured data (...).

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 ...
