This document discusses continuous benchmarking and provides examples of tools and methodologies for implementation. It introduces WireMock for simulating APIs, Gatling for load testing, and ELK stack for log aggregation and visualization with Kibana dashboards. Continuous benchmarking allows anticipating production problems by regularly benchmarking applications and monitoring key metrics.

WireMock
1212/01/2017
• Simulator for http-based APIs (mock server)
• Powerful request Matching (URL, HTTP Method, Query parameters
Headers, Basic authentication (a special case of header matching))
• Record and Playback
• Proxy mode
• Config with java or json

Conclusion
2512/01/2017
_Continuous benchmarking is possible with low
cost
_Anticipate the production possible problem ASAP
_WireMock is therefore perfectly suited for
continuous benchmarking
