TIBCO EMS typical architecture
TIBCO EMS cross-regional architecture in Amazon
The below diagram shows the typical architecture of TIBCO EMS
routing between two TIBCO EMS Servers in different regions, common in many enterprise systems.
TIBCO EMS Server EMS_ORANGE is
deployed in the us-east-1 region and
EMS_APPLE is deployed in
the us-east-2 region:
For application App 1 to communicate with App 2:
-
App 1 uses a topic destination, Topic1 on server EMS_ORANGE to publish messages.
-
Published messages are transmitted to topic Topic1 on server EMS_APPLE using the configured route.
-
On EMS_APPLE, a bridge is configured to move messages from topic, Topic1 to queue, Queue1. Messages are then consumed by App 2.
TIBCO EMS high availability architecture
In this configuration, High availability is provided by
configuring a pair of servers, Primary and Secondary. In a typical enterprise architecture,
two high availability configurations,
shared and unshared.
The shared state setup is the most widely used setup in
enterprise settings. The following diagram demonstrates the Shared State configuration for a pair of
messaging servers:
In the above diagram, a pair of messaging servers share a state by sharing file-based storage. The primary server attains the lock on the shared storage capacity, becomes active, and accepts client connections, while the secondary server remains in passive mode. Meanwhile, the primary and secondary servers will be made aware of one another's status via periodic, heartbeat pings.
In te case of a failover, the secondary server will assume the state of the primary server, and acquire the lock on the shared state.
Note
The above configuration is unable to support more than two servers, and data replication across the servers for durability.
