[SR-Users] Kamailio in VMware with Fault Tolerance on

[Patrick Wakano]

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

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 (5+ 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

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.

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

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,

[Patrick Wakano]

Thanks for your input Sergio!
Our current active-standby uses keepalived to manage the shared IP between
the servers. It works fine. Now we are trying a new architecture as a step
towards a public cloud deployment.

[Sergio Charrua]

then take a look at Pacemaker and Corosync. Both work great!
