Layer 3 of 20

Infrastructure Fabric

Compute, networking, storage, edge, and multi-region topology: reliability, resilience, and global routing foundations.

Responsibilities

  • Provide multi-region compute, networking, storage, and routing foundations.
  • Define availability zones, redundancy, and disaster recovery posture.
  • Expose standardized infrastructure primitives to higher layers.

Key interfaces

  • Ingress/egress routing (DNS, edge routing, load balancing).
  • Service networking and identity (mTLS/service discovery) where used.
  • Storage primitives (object/block/file) and replication contracts.

Operational signals

These are the measurements that tell you whether this layer is healthy in production.

  • Regional availability, packet loss, and cross-region latency.
  • Capacity headroom and autoscaling events.
  • Error budget consumption by region/zone.

Failure modes

  • Regional outage or partial zone failure.
  • Network partitions and inconsistent routing.
  • Capacity depletion during spikes or failover.

Production readiness checklist

  • Practice failover (game days) and validate RTO/RPO.
  • Use multi-region routing with health-based steering.
  • Keep infrastructure changes audited and reversible.
