=== HAProxy === |
|||
Orain uses HAProxy (High Availability Proxy) to load balance web requests to all domains managed by the Orain DNS. Currently we run a single HAProxy instance on prod10 which distributes requests to the least connected server serving MediaWiki. |
|||
HAProxy is also used to terminate SSL requests between MediaWiki servers and the load balancer. As a result, this means all requests to Orain-DNS-managed domains are encrypted when they communicate with prod10 but it de-encrypts them via the Private IP of the MediaWiki servers and then re-encrypts the response. |
