Highly Available Routing with Multi Cluster Gateways

The presentation discusses the use of Gateway API and Multi-Cluster Services to create Multi-Cluster Gateways for advanced routing across clusters, improving application availability and reducing latency.

• Gateway API represents a cloud load balancer for routing configuration
• Multi-Cluster Services enable connecting clusters together for improved availability and reduced latency
• Combining Gateway API and Multi-Cluster Services creates Multi-Cluster Gateways for advanced routing across clusters
• Multi-Cluster routing can improve application availability and demonstrate failover capabilities
• APIs can provide portable multi-cluster routing configuration even when mapped to different underlying cloud infrastructure

The presentation highlights the importance of multi-cluster routing and how it can improve application availability. For example, if one cluster goes down, the application can failover to another cluster, ensuring that the application remains available to users. This is especially important for critical applications that require high availability and minimal downtime.

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.
