Our business systems, whether internal enterprise systems or Internet application systems, require scalable and highly available systems. Scalability and high availability are not isolated. Only by combining them can we achieve the desired results. Scalability is an optional attribute of a system, network, or process.

components. Applications are simple enough without a layered architecture. Most of the work can be done by calling these components. Components developed in different languages need to be combined. For example, Asp.net needs to call COM + components written in VB. Applications must support plug-in technology and can dynamically switch components, such as plug-in technology implemented by. Net reflection technology. We can choose a component-based architecture. If Applications are complex.

From: China Mobile Communication Forum I. CDMANetwork China Unicom announced the large-scale development of CDMA networks and explicitly proposed the implementation of SIM card functions similar to the GSM system in the CDMA system. This action immediately aroused strong repercussions at home and abroad. In China, many people argue over the advantages and disadvantages of the SIM card (called uimcard in CDMA systems) and the air activation Technol

Performance Comparison Between SUSE and RedHat SystemsAs early as a few months ago, SUSE officially released the SUSE Linux Enterprise 12 operating system, which enhances cluster software to improve service availability in physical, virtual, local, and global environments. The new web Console, updated OCFS2 and GFS2 file systems, and the latest ReaR updates for disaster recovery make it easy to protect core business

Whatever the system, the safest way. After debugging, make a backup. If you encounter any major problems, you can recover them directly, which is convenient and easy to handle. The following describes the Linux backup and recovery methods:The backup and recovery system is responsible for backup and recovery beforehand. In the current rapidly developing network environment, no information system on any network can guarantee absolute security. As long as there is a network, There will be various t

So, I've listed some open source software backup tools for everyone.What do you think about when choosing a backup tool for an enterp

Linux operating systems mainly include UNIX operating systems, MINIX operating systems, the GNU program, POSIX standards, and internet networks. Windows operating systems include Windows2003, windows2008, XP, Win7, and so on. What are the different differences between these Windows

Linux disks and file systems?? When we get a brand new disk, we are not able to use it directly, but need to be partitioned, formatted, and mounted before the operating system can recognize and write and read the data. Different operating systems vary in file systems, so the partitioning of disks is not the same.I. Disk 1. Structure?? In the computer field, disk

In the days when the network is booming, network security issues have become increasingly prominent. Black and white channels on the network are fiercely competitive in various fields of network security. The Black Hat community is constantly introducing new technologies to avoid or bypass Network Intrusion Detection Systems (NIDS). NIDS developers are constantly adding Detection techniques to their own products. However, due to the limitations of NID

why Apple iOS OS is running faster than Android, and many people are reacting to Apple's iphone than the average AndroidMobile Phonefluency, which is a phenomenon to be said to be a big problem not to mention, after all, the two are completely two different systems so it's not fair to put it all together in strict contrast. But because Android and iOS are the two major operating systems of the moment, it's

Article Title: differences between LINUX and other operating systems. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. It is very important to know how Linux differs from other operating systems. Here we mainly discuss the oper

Early database management adopted file systems. In a file system, data consists of several named files based on their content, structure, and usage. Files are generally owned by a user or user group, but can be shared by other users. Users can open, read, write, and close files through the operating system. File systems have obvious disadvantages:(1) it is inconvenient to write applications.The Application

Through the comparison and testing of the 3DMark series software, we can see that the test scores and trends of Asus Z99j with NVIDIA GeForce Go 7300 independent graphics card are roughly the same as those of Dell's 6400, the display performance of Windows XP operating systems

Let's take a look at the actual operation of the top command.# Top2. vmstat-Virtual Memory StatisticsThe Vmstat command is used to display more information such as virtual memory, kernel threads, disks, system processes, I/O modules, interrupts, CPU active states, and more. In the default case, the Linux system is not vmstat this command, if you wan

http://news.cnblogs.com/n/84066/ The logo of Linux is a very cute little penguin, and FreeBSD is a small demon holding a fork. Do you often hear people confuse Linux with BSD systems? Yes, I hear a lot of beginners sometimes, even the media say so. There are, of course, a lot of similarities in the two, for example, they are all based on Unix, and basically both types of systems are developed by nonprofi
