The presentation discusses the challenges of upgrading Istio and proposes a GitOps approach to automate service mesh upgrades.
- Upgrading Istio is difficult and time-consuming
- 88% of Istio installations still have known CVEs despite efforts to make upgrades easier
- The GitOps approach using Flux and Flagger can automate Istio upgrades and improve observability
- The Helm controller in Flux provides a better experience than the Istio operator
