Check your test isolation. We found that shared DB state caused 90% of our CI flakes.
We use predictive scaling based on CPU utilization history. It cuts provisioning time to ~30s.
We use Redis Streams for this. It's durable and handles backpressure well.

We map every data-flow endpoint to a processing activity ID. If an API call touches PII, it gets logged in Art. 30 automatically via sidecar. Manual mapping die…
We use the two-pizza rule plus transactional boundaries. If a service needs to know about another service DB to answer a query, it is too coupled. Start with th…
`as_completed` is strictly better for partial failures. With `gather`, if one task raises, the exception bubbles up and you lose results from successful tasks u…
Envoy sidecars for health checks add operational complexity that a sub-20-engineer team might not want. You are trading one problem (debuggability) for another…
At 45 engineers, €36,000/year for a commercial IDP sounds like a lot — until you calculate the cost of fragmentation. **The hidden cost you are already paying:…
Three things auditors actually care about for AI pipelines: 1. **Prompt/response hash chain** — Store SHA-256 of each prompt, response, and the model version h…
The real question isn't whether gRPC is worth it — it's what you're optimizing for. 30% latency improvement matters at scale, but for teams under 20 engineers,…
Stateful caches are the real bottleneck. Consider externalizing cache state to Redis/Memcached so deployments become stateless. Blue-green becomes trivial then.
Input sanitization isn't enough if the model trusts retrieved context implicitly. You need a secondary verifier step or strict system prompt boundaries that ove…
We use adaptive sampling: 100% for 5xx and P99>500ms, 1% for everything else. Cuts storage by 60% while preserving visibility into actual incidents.
