1. Using DNS Forwarders DNS forwarders are for other DNS servers The DNS server that completes the DNS query. The primary purpose of using DNS forwarders is to mitigate the pressure of DNS processing, to transfer query requests from DNS servers to forwarders and to benefit from DNS forwarders potentially larger DNS caches. Another benefit of using DNS forwarders is that it prevents DNS

First, analyze some code when the Java client is started. Memcached allows you to directly set multiple servers attributes to achieve multiple memcahced balancing. The corresponding attribute is weights, which literally means weight. After analyzing the code, it is the same as what I think. The code for starting memcached is usually as follows:Java code Sockiopool pool = sockiopool. getinstance (poolname ); Pool. setservers (

present, another kind of webserver has emerged, which is superior in terms of concurrency, called asynchronous servers Asynchronous Server. The most famous ones are nginx and Lighttpd. The so-called Asynchronous Server is the event-driven in the event-driven mode. In addition to the user's concurrent requests, only one or several threads are required. Therefore, system resources are very small. These are also called lightweight Web

I've been doing TMG planning and implementation of high availability in the enterprise for some time. The most common use of high availability in Windows products is "cluster (Cluster)" and "Network Load Balancing (NLB)", so how do we operate in TMG to achieve high availability? In the Microsoft TMG products to achieve high availability, we generally rely on "TMG array" + "Network Load Balancing (NLB)" to achieve, currently in the enterprise security boundary planning, we generally use one or m

With the rapid growth of the Internet, network servers, especially Web servers, need to provide a large number of concurrent access services as the number of visitors increases rapidly. For example, Sohu receives millions of access requests every day. Therefore, CPU and I/O processing capabilities will soon become a bottleneck for servers that provide large-load

adopts a completely new configuration system that can fully delegate site management, and finally make xcopy deployment of Web applications a reality. The new management API and diagnostic functions make server deployment, management, and troubleshooting easier and more convenient than before. But before the next Windows Server version (codenamed "Longhorn") is about to be released, why should we consider the IIS server application? It is important to consider using it Because Windows Vista wil

Most people run a single MySQL server on a specified machine, but in some cases, running multiple servers is advantageous: you can test the new version of server when the finished server is running. In this case, different servers will run. The operating system usually limits the total process on the number of opened file descriptors. If the system Most people run a single MySQL server on a specified machin
