Here’s a quick look at using Envoy as a load balancer in Kubernetes. Via Alex Mitelman’s Systems Design Weekly 015 , I was pointed to this AWS article on multi-site active-active architectures. It’s a good starting point for thinking about operating your own active-active architecture. Networking.

Whatever DNS name you supply for controlPlaneEndpoint —and it should be a DNS name and not an IP address, since in an HA configuration this value should point to a load balancer, and IP addresses assigned to AWS ELBs can change–will also be added as a Subject Alternative Name (SAN) to the API server’s certificate.

According to Martin, the term SDN originally referred to a change in the network architecture to include a) decoupling the distribution model of the control plane from the data plane; and b) generalized rather than fixed function forwarding hardware. What about virtualized load balancers? What about NX-OS, JUNOS, or EOS?

DDIO allows PCIe devices to DMA information directly to cache–instead of main memory–where it can then be fetched by a processor core. It is, however, very well-suited to workloads that need predictable performance and that work with lots of small packets (firewalls, load balancers, other network devices).

For inbound connectivity, this is where Kubernetes Services come into play; you could have a Service of type NodePort (unique port forwarded by kube-proxy on every node in the Kubernetes cluster) or a Service of type LoadBalancer (which uses a cloud load balancer with nodes & NodePorts as registered backends).

The next step is to add an Elastic Load Balancer (ELB) and distributing the application across two availability zones—this means 2 web instances and 2 instances of RDS (one active and one standby). This sort of architecture gets you greater scale as well as greater redundancy and fault tolerance. How do we go further?
