Not long ago I was in charge of a well-known national manufacturing group's load balancing project. I was deeply touched by the project's application of gslb in a specific environment and learned a lot of related Load Balancing knowledge. Today, let's calm down and think about how to learn a lot through the project. du
Load Balancing (Balance) is one of the factors that must be considered in the design of distributed system architecture.It usually means to allocate the request/data "evenly" to multiple operation units, and the key of load balancing is "uniformity". The uniformity here is not the 10÷2 = 5 we imagined, which is even. N

Today, the ' large server ' model has been replaced by a large number of small servers, using a variety of load balancing techniques. This is a more feasible approach that minimizes the cost of hardware. The advantages of ' more small servers ' outweigh the past ' large server ' patterns in two ways: 1. If the server goes down, the load

After multiple tomcat servers are used for load balancing, the tomcat port is not open to the public, so the tomcat server Load balancer can be accessed precisely. Background: Use Nginx and two Tomcat servers to achieve load balancing, disable tomcat ports (8080 and 8090)

1. Concept: Ribbon load Balancing2. Specific contentNow that all the services have been registered through Eureka, then the purpose of using Eureka registration is to want all the services to be unified into the Eureka processing, but now the problem, all the microservices into the Eureka, and the client's call should also pass Eureka completed. This invocation can be implemented using the Ribbon technology.The Ribbon is a component of a service invoc
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
