Understanding the failure-handling design pattern

When we consider the resilient characteristic of reactive systems, systems and component failures are of utmost concern. It is important to handle these failures in a manner that we determine, which suggests we need to take a purposeful approach to failure-handling. This design pattern has two major components:

• Failure isolation
• Controlled failure

We will look at each of these components next.

Failure isolation

Isolating failure is ensuring that one component's failure does not impact other components. As an example, assume that you are developing an information system for an auto dealer. There are a lot of departments and functions used by the auto dealer and they hope...
