One computing center has 21 classrooms, 150 computers, and more than 40 kinds of teaching software on each computer, but only one operating environment windows. 　　Because of the general performance of computer hardware and the complexity of the software, it takes 3-5 minutes for each student to start and turn on the software-"This is a very embarrassing thing in the ' Cloud computing ' era," said Pan Zhihua, the product director of Ruijie Network Export Gateway, at the Ruijie 2014 Product Strategy conference recently. More embarrassing is, if you want to update or upgrade a software, every ...

Remote invocation is the communication mechanism between system and process, and is the core technology of distributed system development. Remote invocation technology can form a group of computer systems into a network system, the external provision of the overall service, then this group of computer systems constitute a larger, more performance of the computer system. A general statement on the architecture design of the remote invocation service first, we need to understand the following questions: Why is a remote invocation service required in an application software service? What is the problem with the remote Invoke service that solves the software design? I have written an article on the design of distributed Web site architecture, ...

Last week, David Linthicum of the Info World website published an article on the importance of it fundamentals, emphasizing that it can help you better in the area of cloud computing. In this article, linthicum that if you don't have a good understanding of the traditional enterprise IT environment, don't expect much success from cloud computing. In this article, I want to further expand his view, and as server virtualization flourishes, I see a broader trend. Once upon a time, when the server ...

Recently, the news media is more focused on cloud computing, so you rarely hear about high availability. 5 years ago, the IT community was very focused on high availability and cluster development. But in the near term, things are different. In any case, high availability remains one of the key topics in the IT world, says Kai Dupke, senior product manager at SuSE. It has a greater emphasis on cloud computing flexibility and low-cost advantages, so high availability topics seem to be rarely mentioned in cloud computing information. In the past, UNIX and Linux platforms have traditionally assumed most of the high availability (HA ...).

Ask a technician What is cloud computing, and what you most likely get is a boilerplate answer that includes words such as "flexibility", "agility", "Broadband access", "dynamic", "measurable". For most people, however, these definitions do not help them understand what role cloud computing can play in their IT environment. It is for this reason that I developed a method of analogy with the American Thanksgiving dinner to help introduce the concept of cloud computing. So far, this approach has been very useful, and it has enabled us to communicate with our customers when discussing ...
