    <p>Hello,</p>
    <p>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

            <p>Hello,</p>
            <p>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.</p>

                <div>Recently, the issue <a href="https://github.com/kamailio/kamailio/issues/2535" target="_blank">https://github.com/kamailio/kamailio/issues/2535</a>
                  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.</div>
                <div>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?</div>
