We're running aws cdk vs terraform - when to use what? in production and wanted to share our experience.
Scale:
- 969 services deployed
- 26 TB data processed/month
- 5M requests/day
- 10 regions worldwide
Architecture:
- Compute: EC2 Auto Scaling
- Data: DocumentDB
- Queue: EventBridge
Monthly cost: ~$145k
Lessons learned:
1. Multi-AZ costs add up fast
2. CloudWatch logs get expensive
3. Autoscaling needs careful tuning
AMA about our setup!
Can confirm from our side. The most important factor was the human side of change management is often harder than the technical implementation. We initially struggled with performance bottlenecks but found that real-time dashboards for stakeholder visibility worked well. The ROI has been significant - we've seen 2x improvement.
The end result was 99.9% availability, up from 99.5%.
One more thing worth mentioning: we underestimated the training time needed but it was worth the investment.
On the technical front, several aspects deserve attention. First, network topology. Second, backup procedures. Third, security hardening. We spent significant time on testing and it was worth it. Code samples available on our GitHub if anyone wants to take a look. Performance testing showed 50% latency reduction.
For context, we're using Grafana, Loki, and Tempo.
The end result was 70% reduction in incident MTTR.
Feel free to reach out if you have more questions - happy to share our runbooks and documentation.
Here's what we recommend: 1) Test in production-like environments 2) Implement circuit breakers 3) Practice incident response 4) Measure what matters. Common mistakes to avoid: not measuring outcomes. Resources that helped us: Phoenix Project. The most important thing is consistency over perfection.
One more thing worth mentioning: we underestimated the training time needed but it was worth the investment.
The end result was 99.9% availability, up from 99.5%.
Additionally, we found that documentation debt is as dangerous as technical debt.
Our team ran into this exact issue recently. The problem: scaling issues. Our initial approach was simple scripts but that didn't work because it didn't scale. What actually worked: feature flags for gradual rollouts. The key insight was failure modes should be designed for, not discovered in production. Now we're able to deploy with confidence.
The end result was 80% reduction in security vulnerabilities.
For context, we're using Datadog, PagerDuty, and Slack.
For context, we're using Jenkins, GitHub Actions, and Docker.
Looking at the engineering side, there are some things to keep in mind. First, data residency. Second, failover strategy. Third, cost optimization. We spent significant time on monitoring and it was worth it. Code samples available on our GitHub if anyone wants to take a look. Performance testing showed 2x improvement.
The end result was 50% reduction in deployment time.
Additionally, we found that automation should augment human decision-making, not replace it entirely.
I'd recommend checking out the official documentation for more details.
Spot on! From what we've seen, the most important factor was starting small and iterating is more effective than big-bang transformations. We initially struggled with performance bottlenecks but found that feature flags for gradual rollouts worked well. The ROI has been significant - we've seen 30% improvement.
I'd recommend checking out the community forums for more details.
For context, we're using Elasticsearch, Fluentd, and Kibana.
One more thing worth mentioning: team morale improved significantly once the manual toil was automated away.
Great points overall! One aspect I'd add is security considerations. We learned this the hard way when we underestimated the training time needed but it was worth the investment. Now we always make sure to include in design reviews. It's added maybe a few hours to our process but prevents a lot of headaches down the line.
One thing I wish I knew earlier: failure modes should be designed for, not discovered in production. Would have saved us a lot of time.
Additionally, we found that automation should augment human decision-making, not replace it entirely.
Thoughtful post - though I'd challenge one aspect on the metrics focus. In our environment, we found that Jenkins, GitHub Actions, and Docker worked better because documentation debt is as dangerous as technical debt. That said, context matters a lot - what works for us might not work for everyone. The key is to experiment and measure.

This matches our findings exactly. The most important factor was observability is not optional - you can't improve what you can't measure. We initially struggled with legacy integration but found that chaos engineering tests in staging worked well. The ROI has been significant - we've seen 3x improvement.
One thing I wish I knew earlier: cross-team collaboration is essential for success. Would have saved us a lot of time.
I'd recommend checking out the official documentation for more details.
Much appreciated! We're kicking off our evaluating this approach. Could you elaborate on tool selection? Specifically, I'm curious about team training approach. Also, how long did the initial implementation take? Any gotchas we should watch out for?
The end result was 50% reduction in deployment time.

Makes sense! For us, the approach varied using Kubernetes, Helm, ArgoCD, and Prometheus. The main reason was cross-team collaboration is essential for success. However, I can see how your method would be better for fast-moving startups. Have you considered feature flags for gradual rollouts?
The end result was 70% reduction in incident MTTR.
One more thing worth mentioning: we had to iterate several times before finding the right balance.
Additionally, we found that cross-team collaboration is essential for success.
Couldn't relate more! What we learned: Phase 1 (2 weeks) involved assessment and planning. Phase 2 (1 month) focused on pilot implementation. Phase 3 (ongoing) was all about full rollout. Total investment was $50K but the payback period was only 9 months. Key success factors: automation, documentation, feedback loops. If I could do it again, I would invest more in training.
Additionally, we found that failure modes should be designed for, not discovered in production.
Great approach! 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 cross-team collaboration is essential for success. We also found that we had to iterate several times before finding the right balance. Happy to share more details if anyone is interested.
The end result was 50% reduction in deployment time.

Architecturally, there are important trade-offs to consider. First, compliance requirements. Second, failover strategy. Third, security hardening. We spent significant time on monitoring and it was worth it. Code samples available on our GitHub if anyone wants to take a look. Performance testing showed 50% latency reduction.

The end result was 60% improvement in developer productivity.
