Types of Failures
Understand key failure types in distributed systems such as fail-stop, crash, omission, and Byzantine failures. Learn their characteristics, how they affect system behavior, and why handling them is crucial for designing reliable distributed systems.
There are several different types of failures. The following illustration shows the most basic categories.
Let’s see these failures one by one.
Fail-stop
A node halts and remains halted permanently. Other nodes can detect that the node has failed (i.e., by communicating with ...
