Spend more on resilence, get more resilience: who whould've thunk it? Tim Anderson Wed 27 Jan 2021 // 10:30 UTC Share Copy The 2021 State of Chaos Engineering report from Gremlin, based on a survey of 400 companies, has shown a correlation between high availability and frequent use of chaos engineering. Chaos engineering is the practice of deliberately injecting faults into a service to test its resilience. AWS is introducing its own version of this, called Fault Injection Service, early this year, according to CTO Werner Vogels at last month's re:Invent. The new survey from chaos engineering company Gremlin, with contributions from Dynatrace, Epsagon, Grafana Labs, LaunchDarkly and PagerDuty, all companies in the DevOps and observability space, attracted respondents from a range of company sizes from small businesses to enterprises.
