New Relic is being used by Delivery Hero to monitor and improve their application performance data in order to ensure uptime and scalability for rapid growth. The company has shifted from a regionalized system to country-isolated systems, which allows for better local monitoring and tailoring of unique regional-specific needs of customers. This change required creative solutions such as implementing a service mesh and data layers to interconnect environments, refactoring critical applications, and changing naming conventions to ensure compatibility between systems. New Relic is used to understand application performance data, see interdependencies, and be alerted when something is wrong, which helps in promoting a more secure platform and launching global user authentication for customers. The use of open source tools such as Prometheus, Spinnaker, Kubernetes, and Helm has also been beneficial in this initiative.
