HDCP Alignment¶
What is HDCP?¶
HDCP (Hybrid Datacenter Cloud Partnership) is a Defence datacenter modernization concept that combines on-premise sovereign infrastructure with cloud capabilities through strategic partnerships. LRON serves as a personal R&D proving ground for HDCP architectural patterns at hobby-lab scale.
Not a 1:1 replica
LRON does not replicate Defence infrastructure. It validates architectural patterns and principles that apply to HDCP, using commodity cloud resources to explore concepts before they reach procurement specifications.
Concept Mapping¶
| HDCP Concept | LRON Implementation | Scale Difference |
|---|---|---|
| Sovereign infrastructure | Hetzner EU (German DC), self-managed | Single-tenant vs multi-tenant sovereign cloud |
| Federated cluster management | Rancher CE managing K3s cluster | 1 cluster vs N downstream clusters |
| GitOps deployment | Fleet watching GitLab repo | Same pattern, smaller scope |
| DMZ tier / network segmentation | Dedicated CX22 VM + Cilium NetworkPolicy | Same principle, 2 zones vs many |
| Cattle-not-pets compute | Beast VM (ephemeral ARM dev node) | Same principle, 1 node vs fleet |
| WAN emulation / DDIL testing | tc netem with 3 latency profiles | Same tooling, lab conditions |
| Full-stack observability | VictoriaMetrics + Loki + Grafana + alerting | Same stack, smaller scale |
| IaC everything | OpenTofu + Ansible + SOPS | Same principle |
| Zero-trust access | WireGuard + Authelia TOTP + CrowdSec | Same principle, single user |
| Secrets management | SOPS+age + Bitwarden | Same pattern, simpler KMS |
| Edge autonomy | Beast operates with intermittent Hub connectivity | Same principle |
| Backup from code | Full rebuild from Git + Bitwarden | Same principle |
| Micro-segmentation | Cilium eBPF NetworkPolicy | Same technology |
| Browser-based management | ttyd behind Authelia for locked-down clients | Same pattern |
Design Decisions Proven in LRON¶
1. Cilium as the micro-segmentation layer¶
HDCP relevance: Defence datacenters require micro-segmentation between classification levels, partner zones, and management planes.
LRON proof: Cilium CiliumNetworkPolicy CRDs enforce namespace-level isolation between ingress (DMZ), monitoring (Hub), and dev (Beast). Hubble provides network flow visibility for policy validation.
2. Fleet GitOps for multi-cluster deployment¶
HDCP relevance: Federated Defence clusters (CONUS, deployed, exercise) need consistent configuration deployed from a central repository.
LRON proof: Fleet watches a GitLab repo and auto-deploys workloads. Changes to fleet/ are applied within seconds. Rollback is a git revert.
3. Cattle-not-pets for ephemeral compute¶
HDCP relevance: Deployed datacenters are temporary -- they must be provisioned, operated, and torn down without manual intervention.
LRON proof: Beast VM is created from scratch in 5 minutes, operates for hours, and is destroyed with zero state loss. All configuration lives in Git.
4. WAN emulation for DDIL resilience testing¶
HDCP relevance: Deployed Defence networks operate under DDIL conditions. Infrastructure must tolerate high latency and packet loss.
LRON proof: tc netem profiles simulate Normal, Degraded, and DDIL-Severe conditions. K3s agent-server communication tested up to 800ms latency with 15% packet loss.
5. Browser-only management access¶
HDCP relevance: Operational terminals in Defence environments may only have browser access (no SSH client, no VPN).
LRON proof: ttyd behind Authelia TOTP provides full terminal access from any browser, validated from a Defence workstation.
6. VictoriaMetrics over Prometheus for resource-constrained environments¶
HDCP relevance: Edge/deployed monitoring must fit in limited RAM/CPU envelopes.
LRON proof: VictoriaMetrics uses 512 MB RAM vs 1-2 GB for Prometheus with the same scrape targets. Full PromQL compatibility maintained.
7. SOPS+age for secrets-in-repo¶
HDCP relevance: Defence infrastructure must be fully rebuildable from version-controlled code, including secrets (encrypted).
LRON proof: All secrets are SOPS-encrypted in the Git repo. A full cluster rebuild requires only the age key (from Bitwarden) and the repo.
8. CrowdSec for collaborative threat intelligence¶
HDCP relevance: Defence infrastructure benefits from shared threat intelligence without exposing internal data.
LRON proof: CrowdSec's Central API provides community blocklists (inbound intelligence) while only sharing anonymized ban decisions (outbound). No internal data exposure.
What HDCP Does Differently¶
LRON validates patterns, but real HDCP deployments differ in several key ways:
| Aspect | LRON | HDCP (Defence) |
|---|---|---|
| Classification | Unclassified only | Up to NATO SECRET (TEMPEST, SDIP-27) |
| Multi-tenancy | Single user | Multiple units, partners, classification levels |
| Cluster count | 1 | Dozens (fixed + deployable + exercise) |
| Network | Internet-connected | BeMilNet, SecNet, DMZNet, air-gapped options |
| Compliance | Self-governed | NIST 800-171, NATO standards, Belgian KB 20.12.2024 |
| Physical security | Hetzner DC (their problem) | 5-layer model (perimeter to cage) |
| Partnership | Self-operated | Co-sourced with strategic partner (CDR model) |
| Budget | EUR 14.64/month | Multi-million EUR multi-year contract |
| Scale | 3 VMs | Hundreds of servers, PB storage |
| Availability | Best-effort | 99.9%+ SLA with contractual penalties |
The value of small-scale proof
LRON cannot prove that a pattern works at Defence scale. But it CAN prove that a pattern is fundamentally sound, identify integration challenges early, and build operator intuition before writing procurement specifications.
