Hello list,
we are trying to use Artemis HA shared storage cluster which our SaaS
application. In addition to consumers/producers internal to SaaS application
itself, we also have thousands of external consumers/producers which are
installed on client’s premises .
As broadcast is not possible on Google Cloud we are using static discovery
configuration with these connectors:
<connectors>
<!-- Connector used to be announced through cluster connections and
notifications -->
<connector
name="artemis-master">tcp://internal-cluster-dns-1:61616</connector>
<connector
name="artemis-slave">tcp://internal-cluster-dns2:61616</connector>
</connectors>
Our acceptors are also configured to use internal DNS of the hosts on both
cluster nodes:
<acceptor
name="artemis">tcp://internal-cluster-dns-1:61616?tcpSendBufferSize=1048576;tcpReceiveBufferSize=1048576;amqpMinLargeMessageSize=102400;protocols=CORE,AMQP,STOMP,HORNETQ,MQTT,OPENWIRE;useEpoll=true;amqpCredits=10
00;amqpLowCredits=300;amqpDuplicateDetection=true;supportAdvisory=false;suppressInternalManagementObjects=false</acceptor>
We don’t have issues with internal consumers/producers, however when we try to
connect external consumers (via external IP), they are trying to connect via
internal DNS which is probably set in the cluster topology packet.
This is probably expected and by design, but my question is how do we correctly
handle such case? We obviously do not want internal clients to be served via
external IP because external traffic is expensive in the cloud and the
performance would decrease dramatically. Even with static discovery we would
like to have a possibility to expand our cluster in the future, i.e. use the
topology so that clients are configured automatically.
Do we need to have a split-DNS server so that external and internal clients
will see different IP addresses? Or maybe it is possible to have the same node
serving different acceptors on different ports and different DNS names?
Any pointers are much appreciated.
