Latency (response time to user requests) percentiles Transaction throughput per hour/day/week/month/quarter/year. ![]() Monitoring systems and procedures are in place to produce metrics (see below).Systems are created (using IaC) and running in “steady state”.If your leadership’s attitude is to do the minimal and just recover when needed, this is not for you. Preparations for Chaos Engineering effort: Improved availability (reduced unplanned down time) and development velocity. Proof that failure of key resources in each environment results in recovery within RTO and RPO timeframes. RTO and RPO expected and architecture/processes to achieve them are defined and approved by leadership. It involves conducting experiments to expose systemic weaknesses do not become aberrant behaviors in production.Ī sample Acceptance Criteria statement for work on Chaos Engineering is confidence in our production deployments despite the complexity that they represent: Instead of waiting for an outage to “see what happens”, cascading failures when a single point of failure crashesĬhaos Engineering is an investment in moving from a reactive to proactive approach to reliability engineering.outages when a downstream dependency receives too much traffic.retry storms from improperly tuned timeouts.improper fallback settings when a service is unavailable (such as the system not being in a safe state after failure).Server shutdown (by operating system command).System time Change (by “Time Travel” utility).Specific app process killed (by operating system command).Network connections severed (by operating system command).Network bandwidth (competing program hogs bandwidth).Transaction latency (by proxy holding requests). #Run space gremlin as root free#
