Deploy multiple traffic managers with load balance data publisher failover data receiver pattern.

Load balancing events to sets of servers

In this setup there are two group of servers that are referred to as Group A and Group B. You can send events to both the groups. You can also carry out load balancing for both sets as mentioned in load balancing between a set of servers. This scenario is a combination of load balancing between a set of servers and sending an event to several receivers. An event is sent to both Group A and Group B. Within Group A, it will be sent either to Traffic Manager -01 or Traffic Manager -02. Similarly within Group B, it will be sent either to Traffic Manager -03 or Traffic Manager -04. In the setup, you can have any number of Groups and any number of Traffic Managers (within group) as required by mentioning them accurately in the server URL.

Similar to the other scenarios, you can describe this as a receiver URL. The Groups should be mentioned within curly braces separated by commas. Furthermore, each receiver that belongs to the group, should be within the curly braces and with the receiver URLs in a comma separated format. The receiver URL format is given below.

 <DataPublisher>
           <Enabled>true</Enabled>
           <Type>Binary</Type>    <ReceiverUrlGroup>{tcp://127.0.0.1:9612,tcp://127.0.0.1:9613},{tcp://127.0.0.2:9612,tcp://127.0.0.2:9613} </ReceiverUrlGroup>
<AuthUrlGroup>{ssl://127.0.0.1:9712,ssl://127.0.0.1:9713}, {ssl://127.0.0.2:9712,ssl://127.0.0.2:9713}</AuthUrlGroup>
           <Username>${admin.username}</Username>
           <Password>${admin.password}</Password>
           <DataPublisherPool>
               <MaxIdle>1000</MaxIdle>
               <InitIdleCapacity>200</InitIdleCapacity>
           </DataPublisherPool>
           <DataPublisherThreadPool>
               <CorePoolSize>200</CorePoolSize>
               <MaxmimumPoolSize>1000</MaxmimumPoolSize>
               <KeepAliveTime>200</KeepAliveTime>
           </DataPublisherThreadPool>
       </DataPublisher>
