AWS observability: CloudWatch and beyond

Metrics, logs and traces. This post digs into the topic, drawing on recent discussion from Hacker News, Reddit, and the wider community.

The conversation that prompted this post is linked in the sources. I have tried to capture the substance of the discussion rather than just summarize it, because the comments are usually where the real insight lives.

What happened

Managed databases trade operational burden for cost and flexibility. Know what you are giving up.

Backups are not disaster recovery. Test your restores or you do not have backups.

Infrastructure as code is not optional at scale. Clicking in the console is fine for learning and unacceptable for production.

Observability is the difference between knowing something is broken and knowing why. Invest in it before you need it.

Reserved instances and savings plans reward commitment. If your workload is stable, not using them is leaving money on the table.

Autoscaling is not a substitute for capacity planning. It reacts to load; it does not predict it.

Spot instances are free money if your workload can tolerate interruption. Most batch and async workloads can.

The cloud is just someone else's computer, and that someone else is very good at charging you for convenience. The question is always whether the convenience is worth the markup.

Multi-region is not multi-cloud. Running in two AWS regions is redundancy. Running on AWS and GCP is strategy, and it is expensive.

Serverless is great until it isn't. Cold starts, concurrency limits, and vendor lock-in are real costs that show up at scale.

IAM is the foundation of cloud security. Get it wrong and nothing else matters. Get it right and most attacks become much harder.

Cloud cost is the new technical debt. Teams that do not track spend by service and team end up with bills that nobody can explain and nobody can reduce.

Observability is the difference between knowing something is broken and knowing why. Invest in it before you need it.

Backups are not disaster recovery. Test your restores or you do not have backups.

Tagging is boring and essential. Without consistent tags, cost attribution is guesswork.

The shared responsibility model means the cloud secures the infrastructure and you secure everything else. Most breaches are in the everything else.
