Patrick,

I would rely on Corosync and Pacemaker for failover, using a shared IP address between (active + passive) servers. Once the active goes down, Pacemaker switches the shared IP to the passive server that will then become the active server.

Hope this helps,

Hello,

is the active-active architecture still relying on a single shared ip that is migrated between the systems, or do you use two shared ips and each system is associated with one in normal operational mode? Or is anycast?

Cheers,
Daniel

Thanks for the info Daniel! Much appreciated!

Our previous architecture was active-standby with VIP and keepalived, however we are moving towards an active-active approach.

Cheers,

Hello,

I try to stay away from infrastructure, so I do not know the exact technical details and whether it uses Fault Tolerance, but I have customers using VMware, some with rather busy sip servers (50000+ active users) and all runs smooth there. But in this specific case, there is no DMQ, data is shared via database (MySQL), the secondary system being in standby ready to take over the IP of the primary server.

Cheers,
Daniel

Hello list,

Hope you are all good!

Recently, the issue https://github.com/kamailio/kamailio/issues/2535 has been investigated and the utilization of the feature vsphere Fault Tolerance is linked as a source of network latency and probably CPU allocation latency. This increases the chances of the mentioned issue to happen.

So I would just like to ask if anyone out there is using Kamilio in a VMware environment with Fault Tolerance on? How is the experience?

Kind regards,

Patrick Wakano
