Architecture & solutions

Complete reference architecture

Animated reference architecture with eight layers and a governance plane, two enclaves and four deployment models (public cloud, dedicated hybrid, on-prem sovereign, air-gapped sovereign), the cloud / on-prem / air-gapped zone schema, Kubernetes reference and indicative deployment scripts on request.

Deployment models

  • Public multi-tenant cloud (Cloud & hybrid enclave): Tier 1–3 use cases, fastest start, elastic scale, frontier models.
  • Dedicated hybrid (Cloud & hybrid enclave): Mixed estate: cloud orchestration, sensitive data and systems of record stay on-prem.
  • On-prem sovereign (Sovereign enclave): Regulated or sovereign data, connected network but no external model calls.
  • Air-gapped sovereign (Sovereign enclave): Defence, national security, critical infrastructure: no network path to the internet.

Layers

  • Channels & edge
  • Experience & agent interfaces
  • Orchestration
  • AI services
  • Integration
  • Data & knowledge
  • Systems of record
  • Infrastructure

Kubernetes

  • Namespaces & tenancy: One namespace per tier and business unit; tier 3–4 on dedicated node pools; ResourceQuotas per namespace.
  • Model serving: vLLM (or Ollama for small models) on GPU node pools, LoRA adapters hot-loaded per domain, autoscaling on queue depth.
  • Service mesh & network: mTLS everywhere (Istio / Linkerd), default-deny NetworkPolicies, egress gateway with allow-list.
  • Policy & admission: OPA Gatekeeper / Kyverno: signed images only, no privileged pods, labels for data class and tier.
  • Secrets & keys: External Secrets / Vault, keys in KMS or HSM; agent tool credentials short-lived and scoped.
  • GitOps & supply chain: Argo CD from a signed Git repository, SBOM and image signing (Sigstore / cosign), promotion dev → test → prod via CAB.
  • Observability: OpenTelemetry traces of agent steps and tool calls, Prometheus metrics, logs to SIEM and WORM vault.
