front end load balancer

Learning a burst of front-end optimization, it is time to end up, the next step will be in various aspects of the end of the optimization solution.-----------------------------------------------------------------------------------Because scripts block the download of other resources on the page, it is recommended that

Nginx Server Load balancer transmits the parameter method to the backend (the backend is also an nginx server), and nginx Server Load balancer A website uses nginx for load balancing and multiple nginx servers at the backend. Encountered a problem, when it is used as SSL sup

Build a mysql Server Load balancer and a high-availability environment and a mysql Server Load balancer Objective: To use two hosts to achieve Mysql load balancing and redundancy, and achieve dual-master-slave mutual backup; Environment: rhel5.8, mysql-5.0.77, keepalived-1.2

Article Title: Server Load balancer technology is used to build a high-load network site. Linux is a technology channel of the IT lab in China. Including desktop applications, Linux system management, kernel research, embedded systems and open-source, and other basic categories. The rapid growth of Internet makes multimedia network servers, especially Web servers

systems. Distributed and business splitting solves the problem from centralization to distribution. However, each deployed independent business still has single point of failure and unified access portal. to solve single point of failure, we can adopt redundancy. Deploy the same application on multiple machines. To solve the unified access problem, we can add a server load balancer device in

Now, basically all enterprises use the network for daily work. In the network operation of an enterprise, the transmission and data sending and receiving processes are not evenly distributed. Then, using Server Load balancer technology can achieve a balanced concept. So how to implement it? If it is not realistic to purchase large load balancing equipment, softwa

business still has single point of failure and unified access portal. to solve single point of failure, we can adopt redundancy. Deploy the same application on multiple machines. To solve the unified access problem, we can add a server load balancer device in front of the cluster to achieve traffic distribution. Load

. If you have enough funds, you can use up to 100,001 hardware devices. If you already have a technical team, use nginx/haproxy + keepalived to build your own front-end. Balanced methods are flexible, with random, weight, ip, and url options.4. Synchronization depends on what to synchronize. Common files can be synchronized in real time. However, if the database is used, you must select the synchronization

. Therefore, it is not required for small network services for the time being; in addition, it is similar to Nginx/LVS/HAProxy's Linux-based open-source free server load balancer software, which is implemented at the software level, so the cost is very low. Currently, the website architecture is generally reasonable and popular: the Web front-

a request to the vswitch closest to the VS server through a layer-by-layer route. The vswitch forwards the request to the VS server, and the VS Server Load balancer forwards the request to the RS server. In this process, the VIP modifies the MAC address and schedules the request to the real host. In this process, the ARP protocol is used to broadcast in a LAN to find the MAC address of a real host.
