Use traffic mirroring to debug microservices in a production-like environment

The article on InfoQ discusses the topic of traffic mirroring for microservices using Istio in a VPC environment. The authors focus on how to effectively implement mirroring to test new services without impacting production. Traffic mirroring allows engineering teams to control the influence of code changes on real user traffic. The article covers technical aspects, including how to configure Istio for mirroring and what best practices exist in this field. With this approach, engineers can better prepare for introducing new features and ensure their stability in the production environment, which is crucial in microservices where changes can have far-reaching consequences.
