Site_reliability_engineering

# Site reliability engineering ## MicroSim spec - **Recommended sim type:** probability-montecarlo - **Microsimmability score:** 40/100 - **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below. ### Parameters (tunable controls) - `Trials` (number of random samples) - `Failure rate λ` (component hazard rate) - `Redundancy` (number of parallel/backup units) ### What animates Random trials accumulate on the canvas while an estimate (reliability, failure probability) converges as trials and redundancy change. ### Learning objective Relate [[System|system]] reliability and risk to component failure rate and redundancy. ## Links (Wikipedia order)  `;login:` · `Abstraction_(computer_science)` · `Addison-Wesley` · `Agile_software_development` · `Airbnb` · `Aspect-oriented_programming` · `Automation` · `Automation_and_Remote_Control` · [[Availability]] · `Backward_compatibility` · `Buzzword` · `CI/CD` · `Capability_Maturity_Model_Integration` · `Capacity_planning` · `Change_management_(engineering)` · `Chaos_engineering` · `Cloud_computing` · `Compatibility_layer` · `Compatibility_mode` · `Component-based_software_engineering` · `Computer_compatibility` · [[Computer_engineering]] · `Computer_performance` · [[Computer_programming]] · [[Computer_science]] · `Data_center` · `Data_model` · `Data_modeling` · `DevOps` · `Empirical_software_engineering` · `Enterprise_architecture` · `Enterprise_unified_process` · `Entity–relationship_model` · `Essential_systems_analysis` · `Executable_UML` · `Experimental_software_engineering` · `Extreme_programming` · `Formal_methods` · `Forward_compatibility` · [[Function_model]] · `Functional_specification` · `Google` · `IBM` · [[IDEF]] · `ISO/IEC_15504` · `IT_infrastructure` · `Incident_management` · `Incremental_build_model` · [[Information_model]] · [[Information_science]] · `Infrastructure_as_code` · `Iterative_and_incremental_development` · `Latency_(engineering)` · `LinkedIn` · [[Metamodeling]] · `Model-driven_engineering` · `Modeling_language` · `Netflix` · `O'Reilly_Media` · `Object-oriented_programming` · `Object_model` · [[Ontology_(information_science)]] · `Operations_management` · `Packt` · `Programming_paradigm` · [[Project_management]] · `Prometheus_(software)` · `Rapid_application_development` · `Red_Hat` · [[Reliability_engineering]] · [[Requirements_engineering]] · `Risk_management` · [[Robustness_(computer_science)]] · `Round-trip_engineering` · [[Search-based_software_engineering]] · `Service-oriented_architecture` · `Social_software_engineering` · `Software` · `Software_archaeology` · [[Software_architecture]] · `Software_configuration_management` · `Software_deployment` · `Software_design` · `Software_development` · `Software_development_process` · [[Software_engineering]] · `Software_incompatibility` · `Software_maintenance` · `Software_prototyping` · [[Software_quality]] · [[Software_quality_assurance]] · `Software_system` · `Software_testing` · `Software_verification_and_validation` · `Spiral_model` · `Structured_analysis` · `System_administrator` · `Systems_analysis` · `Systems_design` · `Systems_development_life_cycle` · [[Systems_engineering]] · `Systems_modeling` · `Systems_modeling_language` · `TechCrunch` · `USENIX` · `Unified_Modeling_Language` · `Unified_process` · `Universal_Systems_Language` · `V-model_(software_development)` · `View_model` · `Waterfall_model` · `Web_development` · `Website_monitoring` · `Wikimedia_Foundation` > p5.js MicroSim stub · part of Systems Engineering · [Wikipedia source](https://en.wikipedia.org/wiki/Site_reliability_engineering) > Relation: subfield of systems engineering. ## Concept summary Site Reliability Engineering (SRE) is a discipline in the field of [[Software_engineering|Software Engineering]] and IT infrastructure support that monitors and improves the [[Availability|availability]] and performance of deployed software systems and large software services (which are expected to deliver reliable response times across... ## Build checklist - [ ] Claim it: set `status: in-progress` + `lease` + `leased_at` - [ ] Write the child page explaining the concept (tie it back to systems engineering) - [ ] Finalize parameter ranges and defaults - [ ] Implement the p5.js sketch (drawing + control regions) - [ ] Add caption + the learning objective on the page - [ ] Set `status: done` ## p5.js sketch ```javascript // MicroSim: Site reliability engineering let controls = {}; function setup() { // createCanvas(...); create sliders for the parameters above. } function draw() { // background(...); read controls; render probability-montecarlo; respond live. } ``` --- Back to Systems Engineering ---  ## Semiotic profile > *The semiotic universals this article invokes, machine-derived from the crossref — **unverified** (born so).
