Expedia Group's journey to implement GitOps with ArgoCD is a story of innovation, scalability, and overcoming challenges. Our GitOps journey involved migrating from KubeFed to ArgoCD, focusing on extensive scalability testing across hundreds of virtual clusters, set up using open source tool, vcluster. We proactively identified potential challenges and prepared comprehensive test cases tailored to different application flavors. We created three types of applications for testing, with sizes varying between 15-30 resources, including CRDs and jobs, small applications containing 15 resources and large applications containing 30 resources. We experimented with multiple test scenarios, using permutation and combination of applications tested on 300 vclusters, scaling approximately 1,000 applications to 30,000+ across these clusters. We concluded this initiative with determining optimal settings for various tunable parameters in the ArgoCD controllers.

In an era where humanitarian needs are escalating, UNICEF’s Humanitarian Cash Operations and Programme Ecosystem (HOPE) stands out as a beacon of innovation and efficiency. Launched in 2021, HOPE is a digital management information system designed to streamline and secure the delivery of humanitarian cash transfers (HCTs) to vulnerable populations. This session will delve into the technical architecture and the usage of Kubernetes and Open Source Cloud Native projects that bring real-world impact to people in need by showcasing how cloud-native technologies are revolutionizing humanitarian aid
