Incremental Delivery
The framework/plug-in structure that let us can deliver our features incrementally; for picked the features during runtime instead of during commit time, that will help us reduce code branching requirements, make our integration and delivery process faster.
Throughput Throttling
Throughput Controller let the deployment same as the real production deployment structure that not only let us control the volume finer and easier, but also let us find some issues involving multi instances running parallelly (such as: resource concurrent access, load balance and etc.) possible.
Incident Recovery
When the incident happen, the process about the type message involving the issues could be switched back to the legacy part automatically.
