9.4.2 Every server in the cell is a member of the same bus
In this topology, there are multiple appservers, but no clusters. There is one bus and each appserver is a member of that bus.
The pros of this topology are:
- Clients in appservers can connect locally to the bus, improving performance. If only some servers in the cell are members of the bus, then install any messaging applications on those servers.
- Clients running outside appservers can connect to any cell server to perform messaging, providing some degree of high availability for those clients.
- It is possible to have queue points in the same servers as applications that consume messages from them, improving performance.
The cons are:
- This topology is not upgradeable to support high availability or workload management. See the list of cons in 9.4.1, One server in the cell is a member of one bus.
