Stability - Design Tactics

Do not wait forever. Apply to Integration Points, Blocked Threads, and Slow Responses.

Break connection with failing elements. Don't do it if it hurts.

Create compartments that can isolate failure. Save part of the ship.

Avoid fiddling
(human intervention leads to problems)

Avoid Slow Responses and Fall Fast.

Crash components to Save Systems.

Create cooperative demand control
(demand throttling to serviceable levels).

Emulate out-of-spec failures.

Decide at the last responsible moment.

You can't out-scale the load.

Backpressure creates safety by slowing down consumers.

Slow things down to allow intervention.
