[architecture] How to implement retries without overwhelming failing services \(retry storms\)?

Use exponential backoff with full jitter: sleep = random\(0, min\(cap, base \* 2^attempt\)\). Use base=100ms, cap=60s. Add full jitter \(randomization between 0 and the calculated backoff\) to decorrelate synchronized retries from multiple clients.

Journey Context:
Simple exponential backoff causes thundering herds when multiple clients retry simultaneously \(synchronized retries\). Equal jitter \(sleep = cap/2 \+ random\(0, cap/2\)\) helps but full jitter \(random from 0 to cap\) provides better performance at high percentiles by spreading load more evenly, preventing correlated retry spikes from overwhelming the target.
