How does Prometheus compare to Amazon CloudWatch Metrics?

Prometheus uses a pull-based model collecting metrics from instrumented endpoints, while CloudWatch uses a push-based model with AWS SDK. Prometheus is cloud-agnostic and open-source, making it portable across providers. CloudWatch integrates natively with all AWS services without configuration. Prometheus requires operational management; CloudWatch is fully managed within AWS. For Kubernetes environments, Prometheus is the de facto standard.

When should I use Datadog over Amazon CloudWatch for metrics monitoring?

Choose Datadog for multi-cloud or hybrid environments where a single observability plane across AWS, GCP, Azure, and on-prem is needed. Datadog's 600+ integrations, ML-based anomaly detection, and correlated traces make it superior for complex distributed systems. CloudWatch is sufficient and cheaper for pure AWS workloads where native service metrics are the primary concern.

What is Honeycomb and why is it different from traditional metrics monitoring?

Honeycomb focuses on high-cardinality observability using structured events rather than pre-aggregated metrics. Where Prometheus aggregates data before storage (losing detail), Honeycomb stores raw events enabling arbitrary grouping and filtering during query time. This makes it ideal for debugging distributed system performance issues where you need to slice data by user ID, request path, or any other dimension post-hoc.
