DEMOS — DARKFLIB

DEMOSReliability patterns you can break on purpose. The demos need JavaScript.QUEUEING & CAPACITYHow load turns into waiting, where the excess goes, and who adds capacity.

The queueing knee: Why does latency explode when the service is only 85% busy?

Where does overload go?: When requests arrive faster than they can be served, where does the excess end up?

Autoscaler oscillation: Why does the autoscaler keep swinging between too many workers and too few?

RETRIES & RECOVERYHow retries turn a blip into an outage, and how to stop them.

Retry storms: Why does the service stay down after the spike that broke it has gone?

Breaking the loop: Which server-side defence gets a service out of a retry storm?

ALERTINGHow to find out something is wrong without being paged for everything that is not.

SLO burn-rate alerting: Which alerts should page you, and which ones are just noise?

FAILOVERWhat a client does when the service it depends on fails. Live, on real requests.

Circuit breaker: What should a client do when the service it depends on starts failing?

BUILD YOUR OWNEvery control at once, for when you know what you are looking for.

Full sandbox: What happens when every knob is yours?
