Message queue architecture
Recap

3. Introduction to ServiceInsight for NServiceBusScaling with Asynchronous Messaging
Integration pattern – receive
input; process; send output.
Discrete components.
Well suited to distributed
processing.
The VETRO Pattern
Validate
Enrich
Transform
Route
Operate

4. Introduction to ServiceInsight for NServiceBusScaling with Asynchronous Messaging
Single host receives input &
sends 'do processing'
messages to queues.
Hosts can read from queues
without contention.
Allows multiple hosts to run
processing concurrently.
More scale – add hosts.
Message Queue Architecture

Demo: App V2
Asynchronous message sending
Single producer process
Multiple consumer processes
This time with NServiceBus

7. Introduction to ServiceInsight for NServiceBusScaling with Asynchronous Messaging
• NServiceBus reduces boilerplate code
• NServiceBus brings in battle tested
queue infrastructure code
• NServiceBus provides in addition to that
• First Level Retries
• Second Level Retries
• Auditing and more
• NServiceBus is part of a richer platform
