FAQs; Fault Tolerance in Distributed System
1. What is the basic principle of Fault Tolerance?
The basic principle of fault tolerance is to provide a system to continue its working even if any of the parts of it fails and does not affect the performance of the system.
2. What is meant by fault tolerance testing?
Fault Tolerance testing is defined as the process of testing the overall system in order to check for any failure that can occur during performing the intended operation.
3. What is the difference between Fault Tolerance and Load balancing?
Fault Tolerance is a way for working the system even under any failure and makes the system more reliable and robust. Load balancing distributes the load among available processing elements. It ensures better scalability and response time for the users.
4. What is meant by fault in Distributed Systems?
A fault is defined as a weakness or any shortcoming in the system that affects the overall performance and output of the system.
Fault Tolerance in Distributed System
Distributed systems are defined as a collection of multiple independent systems connected together as a single system. Every independent system has its own memory and resources and some common resources and peripheral devices that are common to devices connected together. The design of Distributed systems is a complex process where all the nodes or devices need to be connected together even if they are located at long distances. Challenges faced by distributed systems are Fault Tolerance, transparency, and communication primitives. Fault Tolerance is one of the major challenges faced by distributed systems.
In distributed systems, there are three types of problems that occur. All these three types of problems are related.
- Fault: Fault is defined as a weakness or shortcoming in the system or any hardware and software component. The presence of fault can lead to error and failure.
- Errors: Errors are incorrect results due to the presence of faults.
- Failure: Failure is the final outcome where the assigned goal is not achieved.
