Amazon CloudWatch vs Datadog Network Monitoring
The native-versus-third-party question every AWS team eventually has. CloudWatch is right there, integrated and cheap to start; Datadog is the cross-stack platform you add on top. The trade is breadth and polish against another invoice and another agent.

| The catch | The billing is a notorious trap — 15+ dimensions, tiered log ingestion, per-node Container Insights and $0.30 custom metrics combine in non-obvious ways; teams routinely underestimate spend 2-4×, and it's AWS-only. | Notorious bill surprises — high-water-mark, multi-SKU billing balloons unpredictably, and as a pure NMS it's weaker on topology/config than a dedicated tool. |

Which should you pick?
Pick Amazon CloudWatch if…
Your world is mostly AWS, you want zero extra vendors, and native metrics, logs and alarms are enough — accepting CloudWatch's thinner cross-cloud reach and the way custom metrics and logs costs creep up.
Full Amazon CloudWatch profile →Pick Datadog Network Monitoring if…
You're multi-cloud or hybrid, want correlated infra/APM/network/logs in one polished pane with a deep integration catalog, and the per-host platform bill buys enough productivity to justify itself.

Is CloudWatch enough, or do I need Datadog?
If your stack is mostly AWS and you mainly need metrics, logs and alarms, CloudWatch is often enough and avoids another vendor. Teams reach for Datadog when they are multi-cloud or hybrid, want correlated APM/infra/network in one UI, or find CloudWatch’s cross-service dashboards and alerting too thin for their scale.
Is CloudWatch actually cheaper than Datadog?
At the start, usually — you pay only for what you use and there is no per-host platform fee. But custom metrics, high-resolution metrics, and log ingestion/retention add up, so heavy users can be surprised. Datadog costs more per host but bundles far more capability; price both against your real metric and log volume.
