Decision comparison
Amazon CloudWatch vs Datadog
Choose Amazon CloudWatch when AWS-native operation, cross-account visibility, Container Insights, and managed AWS integration are the primary requirements. Choose Datadog when a team needs a broad SaaS observability suite spanning APM, log management, network monitoring, synthetic monitoring, and real-user monitoring across cloud environments.
Architecture choice. These take different approaches to the same problem. Read the table as a fit question rather than a feature race.
Applies to: Whether the cloud provider's own monitoring is enough, or a third-party platform is needed.
These are different kinds of product — Cloud-Native Monitoring and Observability Platform.
Quick Comparison
| Decision factor | Amazon CloudWatch | Datadog |
|---|---|---|
| Best For | AWS-centric teams needing managed infrastructure, application, container, logs, metrics, and cross-account operational visibility within their existing AWS environment. | Teams operating modern applications across clouds that need SaaS-based logs, APM, network monitoring, user-experience monitoring, tagging, and service-level troubleshooting. |
| Architecture | AWS-native managed observability service combining dashboards, alarms, logs, metrics, Application Insights, Container Insights, metric streaming, and OpenTelemetry integration. | SaaS observability platform using Datadog Agent telemetry collection, unified metrics, logs, traces, APM, network monitoring, synthetic monitoring, and real-user monitoring. |
| Pricing Model | Free tier with published allowances: 10 custom or detailed-monitoring metrics, 1 million API requests (excluding GetMetricData, GetInsightRuleReport and GetMetricWidgetImage, which are always charged), 5 GB of Logs data, 3 custom dashboards, 10 alarm metrics and 1,800 Live Tail minutes per month. Paid usage is billed per unit, not by monthly plan: OpenTelemetry metric ingestion at $0.50 per GB including 15 months of storage, PromQL queries at $0.01 per million samples scanned, PutMetricData at $0.01 per million requests on top of metric storage, Live Tail at $0.01 per minute past the free allowance, metric centralization at $0.05 per GB after the first copy, and Database Insights Advanced mode at $0.0125 per vCPU-hour. Classic custom metrics are tiered at $0.30 per metric for the first 10,000, $0.10 for the next 240,000 and $0.05 beyond 250,000, which AWS states only inside its worked examples.

Which approach fits
Choose Amazon CloudWatch when AWS-native operation, cross-account visibility, Container Insights, and managed AWS integration are the primary requirements. Choose Datadog when a team needs a broad SaaS observability suite spanning APM, log management, network monitoring, synthetic monitoring, and real-user monitoring across cloud environments.
When each approach fits
Choose Amazon CloudWatch if:
Choose it for predominantly AWS-hosted systems, especially when monitoring multiple AWS accounts, container workloads, high-resolution alarms, and AWS service telemetry from one managed platform.
Choose Datadog if:
Choose it for multi-cloud or application-centric organizations that need correlated logs, traces, metrics, network visibility, frontend journeys, and service overviews in one SaaS platform.
These scenarios reflect the available product evidence. Your requirements, existing stack, and team expertise should guide the final decision.
Frequently Asked Questions
What is the main difference between Amazon CloudWatch and Datadog?
Amazon CloudWatch is AWS's managed observability service and is particularly suited to AWS environments. Its supplied capabilities include cross-account observability, Container Insights, Application Insights, dashboards, composite alarms, high-resolution alarms, log-and-metric correlation, and metric streaming. Datadog is a SaaS observability platform focused on bringing together logs, APM, network monitoring, synthetic monitoring, serverless monitoring, and real-user monitoring across clouds, applications, and devices. The practical distinction is AWS-native operational integration versus a broader cross-environment observability suite.
Which is better for small teams?
For a small team running mainly on AWS, CloudWatch is often the more direct fit because it is already part of the AWS platform, has a free tier, and provides managed dashboards, alarms, log handling, metrics, and application visibility. Datadog can be a stronger option for a small team with workloads across multiple clouds or a need for APM, frontend user journeys, synthetic tests, and network visibility in one interface. However, its usage-based model and reported setup learning curve make cost controls and onboarding important.
Can I migrate from Amazon CloudWatch to Datadog?
Yes, but treat the move as an observability redesign rather than a simple data transfer. Inventory existing CloudWatch dashboards, alarms, logs, metrics, Container Insights usage, Application Insights configuration, and cross-account access patterns. Then deploy and configure Datadog Agent collection where appropriate, map alert conditions to Datadog monitors, recreate dashboards, define tagging standards, and validate log, metric, and trace correlation. OpenTelemetry can help standardize instrumentation during the transition. Run both systems in parallel long enough to validate alerts, service coverage, retention needs, and Datadog usage costs.
What are the pricing differences?
CloudWatch has a free tier with published allowances and then bills per unit rather than by monthly plan: metric ingestion is $0.50 per GB, PromQL queries $0.01 per million samples scanned, and metric centralization $0.05 per GB after the first copy. Its cost therefore depends on the AWS observability services and volume consumed. Datadog also has a free tier and usage-based pricing, with paid plans starting at $0.75 per host per month. Its official supplied pricing data also lists $2, $4.40, and $1,000 price points, while logs, metrics, and enabled features can add usage-driven cost.
