[architecture] What is the best retry strategy for transient failures?

Use exponential backoff with jitter, capped at a maximum delay \(e.g., 30 seconds\), and limit total retries \(e.g., 3-5\). Add a circuit breaker to stop retrying when downstream is down.

Journey Context:
Common mistake: using fixed delays leads to thundering herds; linear backoff still causes correlated retries. Exponential backoff spreads retries, and jitter \(randomizing within the interval\) avoids synchronization. Tradeoffs: too much jitter can delay recovery; too few retries may fail on temporary blips. Choose cap to balance user latency and server load. The AWS SDK default retry mode \(standard\) implements this with an initial delay of ~1 second, exponential factor of 2, and up to 3 retries.
