This talk will share a case study of how TikTok manages its global edge clusters with Kubernetes and operates continuous delivery with Argo CD concluding with a demo. The talk will also dive into the scalability challenges faced by Tiktok to manage edge services using Argo CD (with ~100 edge clusters, ~150k CPUs and ~3000 applications), as well as how the Argo community plans to address them in future. TikTok operates a large network of Kubernetes edge clusters around the world, hosting apps such as Tiktok, live and gaming, using cache and traffic acceleration services offered at our edge clusters. The challenge arises when it comes to the deployment management of those edge services on hundreds of edge clusters. Normally, an edge service shares a lot of common configurations when deployed globally, but still has cluster-specific configurations (e.g. resource quota, service hostname, etc.). From this talk, people will learn how to deploy and manage such kind of services using Argo CD.
