This document contains information about chaos engineering and experimenting with latency injection between microservices. It discusses distributing traffic between production, control, and experimental versions of a service called Service A. 98% of traffic would go to the production version, 1% to the control version, and 1% to the experimental version where latency is injected between Service A and downstream services using an injector. This allows experimenting with how systems react to different latency conditions to test resilience and identify problems.
