Founded by Dr. Zhangwensong in May 1998, the Linux Virtual Server Project is one of the earliest free software projects in China. Linux Virtual Server proposes a load balancing scheduling solution based on IP layer and content request distribution based on the requirements of highly scalable and highly available network services. Because the load scheduling technology of this project is implemented in the L
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 balancer. Fi

Hi, today we will learn how to use Weave and Docker to build an Nginx reverse proxy/Load balancer server. Weave can create a virtual network that connects Docker containers to each other, enabling cross-host deployment and Autodiscover. It allows us to focus more on the development of the application rather than on the infrastructure. Weave provides such a great
