Frequently asked questions
What is the difference between APM and infrastructure monitoring?
APM monitors application performance including response times, transactions and errors at the code level, whilst infrastructure monitoring tracks servers, databases and networks. Modern platforms like Datadog and Dynatrace combine both for complete visibility.
Can open-source APM tools replace commercial solutions?
Open-source tools like Prometheus and Jaeger are excellent for cloud-native environments but require significant operational expertise. Commercial platforms offer superior automation, scalability and support, making them more suitable for large enterprises.
How should I choose between cost and features in APM selection?
Consider your organisation's size, existing tooling and required features. Small teams may benefit from free solutions like Prometheus, whilst large enterprises need comprehensive features. Start with free tiers or trials to evaluate before full commitment.
