Lync2013 deployment series Part1: lync2013 introduction and infrastructure preparationPreface:Lync 2013 has been released for a long time. I have been conducting relevant learning and testing. with limited resources, I have installed and deployed the simulated roles, since my work is still very busy, I have not organized the previous deployment into documents until recently for your reference and learning. This series does not involve enterprise speec

From the code structure, nginx can be divided into three parts: infrastructure, concurrency model and application module. We have introduced the modular design of nginx and analyzed the nginx concurrency model. The concurrency model is mainly implemented by the core class module and event class module. The application module mainly refers to the HTTP and mail modules, which implement the functions of nginx as a Web server, reverse proxy server, and ma

Public Key InfrastructurePKI: Public-Key Infrastructure)Public Key Infrastructure (PKI) is a system that provides Public Key creation and management based on the concept of Public Key encryption Public Key Cryptography. It supports efficient data encryption and Key exchange processes.The PKI system is developed by the Internet standards group and NIST. In the PKI structure, a key Certification Authority (CA

According to a survey conducted by Ovum, a well-known research firm in the market, the rapid growth of mobile broadband traffic has prompted operators to consider problems other than the negative benefits of Wi-Fi. However, even though Wi-Fi traffic is being increasingly integrated into most operators' infrastructure strategic plans, carrier-level solutions cannot fully meet operators' needs. According to the survey, many operators are still looking

The Asian cloud helps reebonz, a B2C online retailer in Singapore, better meet large-scale customer growth. before entering the Asian market, the shopping platform was operated and managed by hosting service providers, one major problem they face is the inability to expand their infrastructure based on traffic needs. Smartmachine has helped Asian cloud build a scalable architecture, and benchmark tests show that new platforms can securely and reliably

Remember the development process of a social app--Infrastructure selectionCatalogue [-] Basic Product Form Technology selection The last two weeks are busy developing a social app, because before doing a bit of social things, it was pulled to do the API backend, a head of a complete set of things, there is no PM and all kinds of urging, the process is very relaxed happy full of fun, now the backend has been basically completed, Next

configured through the user Space command, the/proc file system, or the protocol itself. Finally, all the protocols that access the cached function are the same, but different protocols may use different byte lengths of keywords (addresses). Therefore, the infrastructure provides a common way to define the type used by the keyword.The end host needs no configuration or any special browser. This proxy is called a transparent proxy.The host needs to be

1. Overview Dr. Roy Fielding (see Personal homepage) is the main designer of the HTTP and URI protocol issued by the IETF. HTTP and Uri are the two most important web infrastructure protocols, so Dr. Fielding is one of the founders of the Web architecture. In addition to academic excellence, Dr. Fielding has been involved in the design and development of many Open-source software. He was the developer of Libwww-perl, one of the world's earliest HTTP

achieve a specific function of the components, the implementation of the function is pure hardware, but it is also available to the Linux operating system, so need a kernel exists in the infrastructure to drive the FPGA to export to the user.This driver component is xillybus. Xillybus users must put the IP core of the Xillybus module into the FPGA hardware in the FPGA, the kernel will run a Xillybus data forwarding module, exported to user space for

like "noodles" affects the cabinet space utilization and appearance. chaotic scenes are like the tangle of many snakes, which cannot be clarified. We understand how things have evolved so far, but we cannot determine the root cause of this result. Is such chaos the result of technological evolution? More importantly, how can we improve data center cabling? This article explains how to design and implement the data center cabling infrastructure from t
