Nginx gzip compression and load balancing.

To tune performance of my REST endpoints in past I have enabled Gzip compression in my nginx server configuration. So technically a large json response becomes gzipped and the network latency as a result goes down.

There is a good documentation of this feature on the nginx website which does a pretty good job.

However there is a catch which prevents this technique from working on local development system (while the same config works in production linux instance). I finally found an answer as to why this doesn’t work in some of my local environment.

To do static load balancing I use the upstream concept of nginx which is documented again on the nginx website. The performance is reasonable and the implementation is quite simple for a requirement which needs a simple failover implementation. However for advanced implementation we can always go to haproxy which is very good open source load balancer.
