HAPROXY vs NGINX - 10,000 requests while killing servers

"Which is better? NGINX or HAPROXY?" There's no easy answer...however, here's a real-life test-case of what happens during a multi-server deployment scenario: Thousands of requests are pouring in, and we make a deployment: - take one server out of the cluster at a time - deploy application - restart the server The results? Server re-entry to cluster: - HAProxy revisits the dead server almost immediately after it restarts. - Nginx waits a while before revisiting the server Failed Requests: - HAProxy always fails 50-80 requests in this test case - Nginx fails 0 requests - it will only fail requests if you take 2 of the 3 servers down at the same time, in which case you will get the similar result of 50-80 failed requests Speed: - Nginx consistently delivers slightly better results on this scenario, despite keeping one node out of the cluster for a while NGINX Configuration: server { listen 80; location / { proxy_pass http://nodecluster; } } upstream nodecluster { server 22.22.22.2:3000; server 22.22.22.3:3000; server 22.22.22.5:3000; } HAProxy Configuration: frontend http bind *:80 mode http default_backend web-backend backend web-backend balance roundrobin mode http server web1 22.22.22.2:3000 check server web2 22.22.22.3:3000 check server web3 22.22.22.5:3000 check Song credit: http://www.amazon.com/Baby-Come-Back-To-Instrumental/dp/B00864UJCG -~-~~-~~~-~~-~- Also watch: "Responsive Design Tutorial - Tips for making web sites look great on any device" https://www.youtube.com/watch?v=fgOO9YUFlGI -~-~~-~~~-~~-~-
