Zero trust has become our security model for Kubernetes. Key implementations: mTLS with Istio service mesh, network policies for microsegmentation, OIDC authentication with short-lived tokens, and continuous verification of workload identity. We also use OPA Gatekeeper for policy enforcement. The result is defense in depth where no component trusts another by default. How are you implementing zero trust?
Here's how our journey unfolded with this. We started about 6 months ago with a small pilot. Initial challenges included team training. The breakthrough came when we automated the testing. Key metrics improved: 60% improvement in developer productivity. The team's feedback has been overwhelmingly positive, though we still have room for improvement in automation. Lessons learned: measure everything. Next steps for us: add more automation.

Excellent thread! One consideration often overlooked is security considerations. We learned this the hard way when unexpected benefits included better developer experience and faster onboarding. Now we always make sure to test regularly. It's added maybe a few hours to our process but prevents a lot of headaches down the line.

The end result was 60% improvement in developer productivity.
One thing I wish I knew earlier: documentation debt is as dangerous as technical debt. Would have saved us a lot of time.
For context, we're using Kubernetes, Helm, ArgoCD, and Prometheus.
I'd recommend checking out the community forums for more details.
Additionally, we found that the human side of change management is often harder than the technical implementation.
For context, we're using Jenkins, GitHub Actions, and Docker.
For context, we're using Istio, Linkerd, and Envoy.
For context, we're using Vault, AWS KMS, and SOPS.
Some practical ops guidance that might helps we've developed: Monitoring - Prometheus with Grafana dashboards. Alerting - PagerDuty with intelligent routing. Documentation - Notion for team wikis. Training - certification programs. These have helped us maintain high reliability while still moving fast on new features.

Not to be contrarian, but I see this differently on the metrics focus. In our environment, we found that Elasticsearch, Fluentd, and Kibana worked better because failure modes should be designed for, not discovered in production. That said, context matters a lot - what works for us might not work for everyone. The key is to focus on outcomes.
I'd recommend checking out conference talks on YouTube for more details.
Additionally, we found that automation should augment human decision-making, not replace it entirely.

For context, we're using Datadog, PagerDuty, and Slack.
One more thing worth mentioning: the hardest part was getting buy-in from stakeholders outside engineering.
One more thing worth mentioning: the initial investment was higher than expected, but the long-term benefits exceeded our projections.
Wanted to contribute some real-world operational insights we've developed: Monitoring - CloudWatch with custom metrics. Alerting - PagerDuty with intelligent routing. Documentation - Notion for team wikis. Training - pairing sessions. These have helped us maintain low incident count while still moving fast on new features.
