use of load balancer

Server load balancerFirst, let's take a brief look at what server load balancer is. Simply understanding what it means literally can explain that N servers are equally loaded, A server is not idle because of its high load downtime. The premise of server load

I once talked to my colleagues about the Server Load balancer in RAC. When talking about the distribution mechanism on the server side, we couldn't tell you clearly. I would like to summarize it for future use. I once talked to my colleagues about the Server Load balancer in

virtualServer. The entire server cluster structure is transparent to customers, and there is no need to modify the client and server programs. To this end, system transparency, scalability, high availability and ease of management must be considered during design.. Generally, the LVS cluster adopts a three-tier structure, which consists of the following parts:A. Load SchedulerBalancer), which is a front-end server of the entire cluster and is respons

to the background, thus, the background server connection maintained for a second. Synchronous transmission took the backend server for half an hour, the asynchronous transmission only takes one second, the visibility is greatly optimized.2. In the above example, if the background server for a variety of reasons to restart, upload the file will be a natural interruption, which is very annoying to the user a thing, presumably you have uploaded files to half of the experience interrupted. After u

, the communication volume is moved to another host. Network Load Balancing Configuration OverviewNetwork load balancing is a network driver for Windows 2000. Its operations are transparent to TCP/IP network stacks. To ensure optimal network performance, network load balancing usually uses a network adapter to handle customer-to-cluster traffic, while other netwo

Based on the huge network structure, the use of cluster servers brings a lot of traffic and other load problems. In contrast, Server Load balancer technology has also emerged. Every technology requires Product Support. Now let's get to know one of F5 Server Load

by the proxy_next_upstream module is returned.Fail_timeout: The pause time after max_fails failed.Backup: Requests the backup machine when all other non-Backup machines are down or busy. Therefore, this machine is under the least pressure. Nginx also supports multiple groups of Server Load balancer instances. You can configure multiple upstreams to serve different servers. Configuring Server

balancer operation is not triggered. Normally, the accept lock is obtained and new connections are processed. When ngx_accept_disabled is a positive number, the Server Load balancer operation is triggered. Nginx does not process New Connection events at this time. Instead, it only deletes the variable ngx_accept_disabled by one. This means that the
