Cloud architecture lessons from production
Design for Failure:
Every cloud service has an SLA, not a guarantee. Build stateless services behind load balancers, replicate databases across availability zones, and use health checks with automatic failover. Assume components will fail, and design so users never notice.
Right-Size Your Stack:
Not every app needs Kubernetes. Serverless functions and managed databases work brilliantly for event-driven workloads. Containers shine for long-running services with custom dependencies. Match the architecture to the problem, not the hype.
Control Cloud Costs:
Idle resources, oversized instances, and unmonitored storage buckets silently drain budgets. Set billing alerts, use spot instances for batch jobs, and review your cloud bill monthly. Cost efficiency is an engineering skill, not just a finance concern.

Production lessons feel real, not textbook. Sharing with our DevOps guild.
Spot instances for batch jobs cut our ML training costs by 60%.
Spot plus checkpointing is the sweet spot for fault-tolerant batch workloads.
Design for failure mindset shifted how our team writes runbooks.
Serverless vs containers — finally someone explains when to use each without bias.
We use Lambda for webhooks and ECS for long-running workers. Hybrid approach works great.
Multi-AZ failover section matches what we implemented after our last outage.
Cost control section is underrated. Saved our startup a meaningful amount after applying these tips.
Billing alerts alone pay for themselves. Glad the cost tips helped your startup.
