I am looking for a network diagram for a fully HA, redundant Bit Bucket Data Centre using Postgres and Haproxy.
The Atlassian documentation for HA configuration:
is not fully HA since the load balancer is a single point of failure.
Any help greatly appreciated.
I don't think we have such a diagram to hand, but the general principle of clustering the load balancer for redundancy could be overlaid.
In short, instead of a single load balancer in front of the application nodes you could have multiple nodes, all doing the same job, with technologies such as keepalived to provide high availability.
Here is some information about doing this with haproxy...
thanks for the info. I have since added redundancy on the load balancer using keepalived. I have added a hot standby for Postgres - failover is manual however. There is no ready made solution for automatic failover with Postgres. I looked at a solution which used 'Governor' a Python script which performs pacemaker like functionality. It also etcd and haproxy. It looked fairly complex so I elected not to use it:
Hello folks! To the member of organizations who are still running their Atlassian applications on the server, we are on the side of the bridge, and if we need to sail the boat with confidence either...
