We went through something very similar. The problem: scaling issues. Our initial approach was ad-hoc monitoring but that didn't work because lacked visibility. What actually worked: automated rollback based on error rate thresholds. The key insight was observability is not optional - you can't improve what you can't measure. Now we're able to detect issues early.
One thing I wish I knew earlier: observability is not optional - you can't improve what you can't measure. Would have saved us a lot of time.
We hit this same problem! Symptoms: high latency. Root cause analysis revealed network misconfiguration. Fix: increased pool size. Prevention measures: better monitoring. Total time to resolve was 15 minutes but now we have runbooks and monitoring to catch this early.
One thing I wish I knew earlier: starting small and iterating is more effective than big-bang transformations. Would have saved us a lot of time.
The end result was 60% improvement in developer productivity.
Additionally, we found that starting small and iterating is more effective than big-bang transformations.
While this is well-reasoned, I see things differently on the team structure. In our environment, we found that Istio, Linkerd, and Envoy worked better because automation should augment human decision-making, not replace it entirely. That said, context matters a lot - what works for us might not work for everyone. The key is to experiment and measure.
One thing I wish I knew earlier: security must be built in from the start, not bolted on later. Would have saved us a lot of time.
One more thing worth mentioning: we discovered several hidden dependencies during the migration.
We created a similar solution in our organization and can confirm the benefits. One thing we added was compliance scanning in the CI pipeline. The key insight for us was understanding that documentation debt is as dangerous as technical debt. We also found that we underestimated the training time needed but it was worth the investment. Happy to share more details if anyone is interested.

This is a really thorough analysis! I have a few questions: 1) How did you handle authentication? 2) What was your approach to backup? 3) Did you encounter any issues with costs? We're considering a similar implementation and would love to learn from your experience.
Feel free to reach out if you have more questions - happy to share our runbooks and documentation.

For context, we're using Istio, Linkerd, and Envoy.
