Remote calls fail. Networks crash. Services stop. You need a plan to keep your system running.
Retries fix short errors. Use them for network timeouts or connection resets.
- Use exponential backoff.
- Double the wait time between tries.
- Add random jitter to spread traffic.
Do not retry every error.
- Retry HTTP 5xx errors.
- Retry network timeouts.
- Skip HTTP 4xx errors. Retrying a bad request wastes resources.
Set a limit on retries. Set a deadline. If a request fails 5 times in 30 seconds, stop. Fail fast.
Circuit breakers stop you from hitting a failing service.
- The circuit opens when failure rates are high.
- Calls fail immediately.
- The system tests the service later to see if it recovered.
Do not over-engineer for scale you do not have. Build the simplest thing first. Measure it. Optimize only where data shows a need.
Add logging and metrics from day one. You do not fix what you do not see.
Try this now:
- This week: Audit your backend for these patterns.
- This month: Try one new pattern like a message queue.
- This quarter: Automate your deployments.
