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 ...

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 ...

The benefits of server virtualization now are significant, and it is a natural choice to implement the technology. First, server virtualization makes more use of computing resources than physical servers, because you can run many different virtual servers on a single physical host. In fact, the number of common server instances that a single current server can handle at the same time can be a surprise to you. Another great advantage of server virtualization is the ability to transfer a running virtual server between multiple physical hosts, balancing the load and facilitating maintenance. You can also use the virtual server snapshot, in the change ...

One of the key decisions in setting up a private cloud infrastructure is to choose the storage platform where the cloud is deployed. Storage is a key component of the infrastructure that plays a pivotal role in the overall performance of the private cloud. In addition, because the storage decision involves a relatively large scale of investment, the cycle is longer, so its importance is stronger. When choosing the right platform, there are several factors that must be taken into account: protocol, capacity, performance, scalability, manageability, and cost. In addition to the determinants of these criteria, you have to make sure that the storage device you choose does not ...

IT industry has different views on cloud computing, it is still one of the hottest IT vocabulary in recent years. What exactly is cloud computing, and how does it help us to focus on enterprise R&D informatization?

Although it industry has different views on cloud computing (clouding Computing), it is still one of the hottest it vocabularies in recent years.       What is cloud computing, and how does it help the enterprise research and development information that we are concerned about? More commonly said, cloud computing is hardware + software + services. These three are not simply added, for the research and development of information, cloud computing should be defined as, adapt to research and development requirements of the hardware and software reasonable collocation, and for research and development to provide easy-to-use, high ...
