Fault Tolerance vs Redundancy vs Reliability Engineering

Fault tolerance, redundancy, and reliability engineering are three interconnected concepts in system design, each with its own strengths and weaknesses. While fault tolerance focuses on withstanding failures, redundancy ensures continuity through duplication, and reliability engineering aims to prevent failures altogether. Companies like Google, Amazon, and Microsoft invest heavily in these areas to ensure their systems, like Google Cloud, Amazon Web Services, and Microsoft Azure, can handle failures and maintain high uptime, similar to how Tim Berners-Lee designed the World Wide Web to be resilient and fault-tolerant.
