Enterprise Application Architecture with .NET Core

Fault tolerance

In an enterprise distributed system, there is a high possibility of error generation due to any mechanical or algorithmic issue. It is defined as a system fault that leads to failure on executing the underlying applications.

In general, faults are classified into three major categories. They are as follows:

• Transient fault
• Intermittent fault
• Permanent fault

Transient faults occur once and then disappear, so it is very difficult to reproduce and resolve the bug. Let me provide a simple example. In a network messaging process, it may be possible to loose data connectivity, and it is pretty hard to reproduce the exact situation. This characteristic is considered the key factor to categorize transient faults.
