Software load balancing is generally implemented in two ways: software load implementation based on the operating system and software load implementation based on third-party applications. LVS is a kind of soft load based on the Linux operating system. HAProxy is an open-sou

Using Web Sphere Edge Server to build Load Balancing for cold rolling Systems A user's ERP system has been running for eight years. The Cold Rolling Workshop system has been running for nearly five years. Its core business system is the cold rolling Data Summary Query System, which is built based on the WAS, DB2, and Power minicomputer environment, stable Operation till now. Since the cold rolling query fun

result is also not conducive to the promotion of software. So how do you cross this bottleneck and increase the concurrency of MySQL? There are many methods, such as distributed database, read/write separation, high available load balancing, increasing cache server and so on. The previous article has introduced a read-write separation scheme, and next I will explain MySQL high-availability

The theme of the Technical Salon (http://linux.chinaunix.net/bbs/thread-1019366-1-1.HTML), it is a pleasure to be able to discuss with many industry elites,

, listen, frontend, and backend are proxy segments. frontend is used to match the domain name or URI of the client request. backend defines the backend server cluster. listen is the set of frontend and backend, sometimes only listen can be used to replace frontend and backend.
