What if some of our Reactive System Components fail to work due to a heavy load, or crash due to some issues? It does not give a good impression to the end users. Nowadays, every system should work normally and should be 100% available all the time, even if our System's critical components fail to work.
How to solve this problem? A proven solution is Replication.
The Replication technique allows us to distribute our Reactive System components into different Replicas across the clusters, so that our system is available all the time and supports fault-tolerance, high performance, high availability, and responsiveness.
In this section, we will discuss one of the important Reactive Replication Patterns: the Active-Passive Replication Pattern.
Observe the following Reactive System scenarios:
