What does "resilience" mean in programming?
resilience is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
The ability of a system to recover quickly from failures and continue operating. A resilient system uses retries, circuit breakers, fallbacks, timeouts, and graceful degradation to handle partial failures without a total outage.
Example
"The payment service is resilient — it retries with exponential backoff and falls back to a queued payment if the provider is down."
