Software is everywhere these days - from our phones to cars and appliances. That means it's important that software systems are dependable, robust, and resilient. Resilient systems can withstand failures or errors without completely crashing. Fault tolerance is a key part of resilience. It lets systems keep working properly even when problems occur.
In this article, we'll look at why resilience and fault tolerance matter for business. We'll also discuss core principles and strategies for building fault-tolerant systems. This includes things like redundancy, failover, replication, and isolation. Additionally, we'll examine how different testing methods can identify potential issues and improve resilience. Finally, we'll talk about the future of resilient system design. Emerging trends like cloud computing, containers, and serverless platforms are changing how resilient systems are built.
