The digital systems of IKEA are situated in public cloud and private data centers around the world. In this talk we’ll highlight some of the challenges – and opportunities - we faced in setting up a large scale, multi-cluster distributed Kubernetes environment across our data centers. We’ll share how we have used Cilium and its eBPF features to have a better scaling profile, to improve observability and even to replace some of our proprietary load balancers. * Connecting Kubernetes workloads across our BGP network * Protecting multi-tenant workloads with multi-cluster network policy * Cilium support for multi-homed pods * Mimicking availability zones with Cilium ClusterMesh * Use Cilium with XDP, ServiceType Loadbalancer and Ingress to replace our proprietary load balancer fronting workload. You’ll leave this talk understanding how you can use Cilium and its eBPF capabilities to build and instrument your network and obtain great observability.
