, therefore, the destination address of the returned data packet will be 200.110.50.1, and the source address will be 192.168.1.1. The final returned data packet will be returned to the Server Load balancer server. There are two solutions: 1. the Server Load balancer server uses a dual-nic, which is an internal and

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 Balance (SLB) balances the

, you can also consider suchTechnology: Use a proxy server to evenly forward requests to multiple servers to achieve load balancing. 3. address translation gateway Server Load balancer supports the address translation gateway of Server Load balancer. You can map an

Nginx series ~ Implementation of Server Load balancer and WWW server, nginx Load Balancing The last two lectures are mainly about the Nginx environment, which does not involve the development of the real environment. In this example, describe how to configure Nginx for the Server Load

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 front of the c

This time with the Ribbon and Eureka after the integration of the user no longer pay attention to the specific Rest service address and port number, all the information is obtained through Eureka complete.2.2. Ribbon Load BalancingThe above code shows that there is a load-balanced annotation in the Ribbon: @LoadBalanced, it means that

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) in the firewall, and open only port 80 to the
