architecture, in this way, if one of the MySQL Databases goes down, the other can temporarily take on all the loads, and the database of the down server can be instantly and completely restored based on the database of the active host, to achieve high availability.

interval between the previous session completion and the next session comes back is smaller than the timeout value, bigip will keep the new connection for session persistence, but if the interval is greater than the timeout value, bigip considers the new connection as a new session and balances the load ｡ The original address-based session persistence is easy to implement. It can be implemented only based on three or four layers of data packets, effi

Core Tip: Goal: To use Apache and tomcat to configure a Web site that can be applied, to meet the following requirements: 1. Use Apache as the httpserver and connect multiple Tomcat application instances, and load balancing. 2. Set the Session Timeout time for the system, including Apache and tomcat 3. List of blocked files for the system, including Objectives:To use Apache and tomcat to configure a Web site that can be applied, you must meet the foll

Let's start with a quick look at what is load balancing, which is interpreted literally to explain the average load sharing of n servers, not because a server is under-loaded and idle on a single server. Then the premise of load balancing is to have more than one server to achieve, that is, more than two units can be.Test environmentBecause there is no server, th

firewall to Internet users for access. The reverse proxy can also provide load balancing for multiple servers in the backend, or provide buffering services for servers with slower back-end. In addition, the reverse proxy can enable advanced URL policies and management techn
