Automation and management

This blog post presents the performance analysis of Identity Management (IdM) when encrypted DNS (eDNS) is introduced in an Red Hat OpenShift 4.20 cluster. The post includes a detailed discussion on the architecture of the setup, tuning of IdM, and performance testing of the system under various scenarios. The results demonstrate that the system can sustain high throughput and low latency even with eDNS, making it a suitable choice for secure and high-performance DNS solutions.
