aws network load balancer

DNS load balancing technology is to configure multiple IP addresses for the same host name on the DNS server, the DNS server returns different resolution results for each query based on the IP address recorded by the host in the DNS file, and directs the client access to different machines, so that different clients can access different servers to achieve load balancing.　　 The advantage of DNS

1. Introduction to HAproxy HAproxy is a high-performance proxy server. It provides Lay4 and Lay7 proxies, featuring Healthcheck, Server Load balancer, and access control. It can support tens of thousands of concurrent connections with excellent performance. In addition, the HAproxy operating mode enables it to be easily and securely integrated into the current architecture, while protecting the web servers

1. Like Apache, they are both HTTP server software and adopt Modular Design for function implementation. They all support common language interfaces. At the same time, they also support forward and reverse proxies, virtual hosts, and URL rewriting,CompressionTransmission, SSL encrypted transmission, and so on. However, in terms of execution efficiency, nginx processes faster and consumes less memory resources. In addition, nginx also supports fcgi, which is not supported by Apache. 2. nginx adva
