+## GDC 2023: Open Source Game Development Summit: Agones and Quilkin: OSS Multiplayer Game Server Service Mesh on Kubernetes

+(Does not require GDCVault access to watch)
+
+Previous talks have looked at two open source projects: Agones, the platform for orchestrating and scaling 
+dedicated multiplayer game servers on top of Kubernetes, and Quilkin, an extensible UDP proxy specifically built 
+for protecting, observing and authenticating game server communications.
+
+On the surface this seems like a very powerful combination, but manually integrating the two can be a tricky and 
+intimidating process. You need to know and understand the Kubernetes API and its client libraries, and then tie it 
+into Quilkin's xDS compliant API implementation all through some custom code - which is a large and complex amount 
+of work (and a lot of acronyms).
+
+In this talk, Mark Mandel, Developer Advocate at Google Cloud, will look at how anyone can utilize Quilkin's native 
+Agones integration to provide a turnkey solution for proxying UDP traffic to game servers providing an extra layer 
+of protection and observability when orchestrating game servers on top of Kubernetes.
