Frequently asked questions

What is the difference between open-source and SaaS monitoring tools?

Open-source tools like Prometheus and Grafana require self-hosting and operational management but provide unlimited free usage and deep customisation. SaaS platforms like Datadog handle hosting and scaling automatically with per-usage pricing, offering faster time-to-value and managed support at higher costs.

How do I choose between Prometheus and Datadog?

Choose Prometheus for Kubernetes-native deployments prioritising cost and open-source flexibility with willingness to maintain infrastructure. Select Datadog for enterprises needing all-in-one observability, superior UX, and managed support without operational overhead, accepting higher costs.

Should I pick a single observability platform or build a stack?

Single platforms like Datadog reduce tool sprawl and simplify onboarding, suitable for teams wanting unified experiences. Stacks combining Prometheus, Grafana and Loki offer flexibility, cost control and customisation, requiring greater operational expertise and integration effort.
