AWS

Big picture: the network comes first. Names and container services sit on it. Streams are a separate path for data that moves continuously.

Reading order

  1. VPC: the AWS inventory. The address space itself is VPC, under Networking.
  2. Route 53: DNS for those addresses.
  3. ECS: running containers without running the cluster yourself.
  4. EKS: a Kubernetes control plane run by AWS.
  5. EMR on EKS: Spark and the rest of EMR, scheduled onto that cluster.
  6. Kinesis: a durable stream of records.
  • The network: interfaces, the next hop, and a container, on one drawing.
  • VPC: that same model as an address space in AWS.
  • CIDR: how a subnet's prefix is written.
  • NAT: a NAT gateway rewrites private sources the way a home router does.
  • Kubernetes: the system EKS is running.
