Dubbo is integrated and used with Zookeeper and SpringMVC (load balancing and fault tolerance) and dubbozookeeper
With the development of the Internet, the scale of website applications is constantly expanding, and conventional vertical application architectures cannot cope with this problem. distributed service architectures and mobile computing architectures are imperative. Dubbo is a distributed service
Several implementation ways of Web load balancingSummary:Load Balancing (Balance) is an application of cluster technology (Cluster). Load balancing can spread the work tasks across multiple processing units, increasing the concurrency processing power. The most common application for
device in front of the cluster to achieve traffic distribution.Load Balancing (Balance), which means that load (work tasks, access requests) are balanced and distributed across multiple operating units (servers, components) for execution. is the ultimate solution for high-performance, single-point-of-failure (high availability), scalability (horizontal scaling).This article is the first article on

Part VII: Go microservices-service discovery and load balancing
This section deals with two basic parts of a robust microservices architecture-service discovery and load balancing-as well as how they facilitate the horizontal scaling of i
This article is the first article of load Balancing, which introduces load balancing algorithm and hardware load balancing. Part of the content is excerpted from reading notes. three, load
In the article has been mentioned, enterprises in the resolution of high concurrency problems, generally have two directions of the processing strategy, software, hardware, add load balancer on the hardware to distribute a large number of requests, software on the high concurrency bottleneck: The database +web Server Two add a solution, One of the most commonly used add-on load scenarios for Web servers is

location commands is much less load on Web servers than executing service requests, you can design a server with Load Balancing Based on this function. When the Web server considers itself to be overloaded, it will not directly send back the webpage requested by the browser, but return a locaction command, let the browser go to other servers in the server cluste
Network Load Balancing
What is Server Load balancer?A server Load balancer consists of multiple servers in a symmetric manner.It has an equivalent position, and can provide external services independently without the assistance of other servers. ThroughLoad Balancing
In multi-core CPUs, it is important to ensure that the tasks assigned to each CPU have a good load balance in order to perform the performance of multiple CPUs well. Otherwise, some CPUs are running, others are idle, and they are not able to perform the benefits of multicore CPUs.
To achieve a good load balance there are usually two scenarios, one is static load
There are three different ways to deploy Apache as a loadbalance predecessor, respectively:
1 The allocation of polling equalization strategy
Enter Apache's conf directory, open the httpd.conf file, and add at the end of the file:
proxypass/balancer://proxy/#注意这里以 "/" End
Balancermember http://192.168.6.37:6888/
Balancermember http://192.168.6.38:6888/
Let's look at the parameter "proxypass/balancer://proxy/" above, where "Proxypass" is the command to configure the virtual server, "/" to rep
following point in time:1, non-running normal processes become real-time processes (such as through the Sched_setscheduler system call);2, after the dispatch (there may be a real-time process is preempted by higher priority real-time processes);3, the real-time process is awakened, if not immediately run on the current CPU (it is not the current CPU on the highest priority process);It seems that the load balancin

Microsoft Application Center 2000 Component Load Balancing Technology Overview
Author: Chris Rees
This technical overview will discuss Microsoft Application Center (Application Center) Component Load Balancing technology (CLB).
Introduction
Microsoft Application Center (Application Center) is part of the
protocols, such as the Outlook Web App. So on the load balancer this layer, no longer special need for the load office weighing products to support client affinity.Let me say a few more words, from the level of the mailbox connection to the level of the Web connection request. As mentioned earlier, older versions of Exchange have problems requiring clients to re-authenticate without client affinity support
In multi-core CPUs, to make full use of the performance of multiple CPUs, you must ensure a good load balance for the tasks allocated to each CPU. Otherwise, some CPUs are running and others are idle, so they cannot take advantage of multi-core CPUs.There are usually two solutions to achieve a good load balancing: static load
The advantages of Network Load Balancing
1. Network Load Balancing allows you to propagate incoming requests to up to 32 servers, where you can use up to 32 servers to share external network request services. Network Load Balancing
If you do not know how to install nginx in Linux, refer to the previous article.
The configuration of nginx Server Load balancer is much simpler than that of Apache. Using nginx for Server Load balancer will not describe the configuration of the Tomcat cluster. If you do not understand the configuration of the Tomcat c
CDN Load Balancing technology is the core of the whole CDN acceleration system, so what is the role of load balancing technology? Before introducing the CDN load balancing technology, we first understand the role and significance
Load balancing is composed of multiple servers in a symmetrical way of a server set, each server has the equivalent status, can be provided to the external service alone without the assistance of other servers. Through some load-sharing technology, the externally sent requests are evenly distributed to one of the servers in the symmetric structure, and the server
