I have a need to deploy a High Availability Load Balanced reverse proxy solution. We have a back end web service that requires resilience. To achieve this I’ve been looking at Nginx and Keepalived. The Nginx Plus product appears to contain high availability support – but we’re in the realms of zero budget and open source/community supported products.
The front end reverse proxy I’ll use is Nginx, but it could be anything. The clever part is going to be using keepalived to pass a single IP address between two servers.
