SberBank story: moving Istio from PoC to production Igor Gustomyasov, Sber Maksim Chudnovskii, IBM Sber position across key areas Best client experience Technological leadership In financial services tuning is required 1. Resource consumption 2. Resource Mounts (#15517) 4. Tests on the production-size environment aren’t a waste of time 1. Istio Discovery Restarts (#25495) 2. Proxy Probes (#26792)

way of validating that security expectations in the code were implemented when deployed. Each environment was deployed following Istio Documentation using istioc tl. The assessment included many open customizations to fit it into different envi- ronments, but it’s difficult to say which is a hardened, production-ready approach. Having a secured profile with an opinionated cluster configuration will help guide ing guidelines first as it will give administrators more confidence that they are building an environment following best practices. Pursuing something formal such as CIS benchmarks is not recommended in

predicted that more than 75% of worldwide organizations would run containerized applications in production by 2022. Confidence of this prediction demonstrated the value of cloud native technologies for and security. Relying on upstream Kubernetes isn't enough for teams deploying Kubernetes into production. Basic Kubernetes installations are plagued by a lack of central visibility, inconsistent security metal and "any other provider." Cloud provider installers require administrator access to the environment to create the resources but can operate without administrative access once installation is complete
