Deploying applications across multiple clusters can improve availability and reduce latency. Until recently, connecting clusters together was quite challenging and often required manual configuration that varied across environments. Fortunately, we can use two of the newest Kubernetes APIs to dramatically simplify this. In this talk, Liwen and Rob will show how Gateway API and Multi-Cluster Services can be combined to create Multi-Cluster Gateways, enabling advanced routing across clusters. This talk will cover some important use cases for multi-cluster routing, including examples of how multi-cluster routing can improve the availability of your application. They will demonstrate how to achieve high availability on your applications using multiple clusters, showing how failover from one cluster to another can work. Finally, they will put the pieces together to show end to end demos of multi-cluster routing using the same Gateway API and MultiCluster Service configuration. You will see how these APIs can be used to provide portable multi-cluster routing configuration, even when they are mapped to different underlying cloud infrastructure. They will show how advanced features of Gateway API can be combined with the multi-cluster capabilities of the Multi-Cluster Services API.
Rob is an open source enthusiast currently working on Kubernetes Networking at Google. He's been a maintainer of Gateway API since the very early days of the project and led the development of other Kubernetes networking APIs like EndpointSlices.
Liwen is a Software Engineer at AWS focused on improving AWS VPC networking for Kubernetes. Her first major Kubernetes project was design and development of AWS VPC CNI plugin for Kubernetes networking over AWS VPC. She is an active member of the Gateway API community and implemented...
