Reusable Architecture IP
Architecture Patterns & Playbooks
Reusable architectural assets — patterns, decision frameworks and implementation playbooks — developed from recurring enterprise problems so delivery teams do not solve the same problem from first principles every time.
Each pattern documents: Problem · Context · Architecture · Components · Data flows · Key decisions · Constraints · Security considerations · Implementation guidance · When NOT to use. That final section — when not to use — signals mature architecture judgement.
Cloud & Platform
Azure Enterprise Landing Zone
Subscription topology, network hub-and-spoke, identity, policy, monitoring, security baseline, DevOps integration. For regulated organisations onboarding at enterprise scale.
ARCHITECTED
Secure Cloud Migration Pattern
Discovery → categorisation → wave planning → target design → migration → validation → operate. Handles rehost / refactor / rearchitect / rebuild decisions with risk gates.
DELIVERED
Hybrid Connectivity Pattern
ExpressRoute + VPN failover, VNet peering, private endpoints, DNS design, hybrid identity, encrypted transit. For organisations with retained on-premise estate.
ARCHITECTED
Identity
Enterprise Identity Control Plane
Federated authentication, lifecycle provisioning, privileged access, event-driven security telemetry. Vendor-neutral — SCIM 2.0 · SAML · OIDC · OAuth 2.0 · Kafka/AMQP.
ARCHITECTEDDELIVERED
Joiner-Mover-Leaver Architecture
Automated lifecycle across HR source → identity governance → downstream applications. Reduces manual provisioning and standing privilege.
DELIVERED
Privileged Access Reference Architecture
Tiered admin model, just-in-time elevation, session recording, vaulted credentials, secure admin workstations, break-glass procedures.
ARCHITECTED
Integration
API Integration Pattern
API gateway, versioning, throttling, authentication, observability. REST + GraphQL + gRPC. Contract-first with schema governance.
ARCHITECTED
Event-Driven Architecture Pattern
Kafka / Event Hubs / Service Bus, event schema registry, replay, dead-letter, idempotent consumers. For high-volume decoupled workflows.
ARCHITECTED
Third-Party Integration Pattern
Vendor onboarding, mTLS, API keys vs OAuth, allow-list network controls, monitoring, contractual SLAs mapped to technical controls.
ARCHITECTED
Data
Secure Data Exchange Pattern
Signed payloads, encryption at rest & in transit, tokenisation, consent enforcement, audit trail, sovereignty tagging.
ARCHITECTED
Enterprise Telemetry Architecture
Log source inventory, normalisation, hot/warm/cold tier, retention, cost governance, KQL detection engineering.
DELIVERED
Data Classification & Control Pattern
Tag-driven classification, Purview integration, DLP policies, encryption at classification, access controls, retention mapped to classification.
ARCHITECTED
AI
Enterprise RAG Reference Architecture
Ingestion → chunking → embedding → hybrid search → orchestration → model → response. Azure OpenAI + AI Search + Semantic Kernel with governance, observability and quality gates.
ARCHITECTEDDELIVERED
AI Document Processing Architecture
Document Intelligence + LLM extraction + validation + human-in-loop + downstream systems. 2.5M+ documents/year, 94–96% accuracy.
DELIVERED
AI Governance Architecture
Model registry, prompt/response logging, PII redaction, evaluation harness, drift monitoring, EU AI Act & ISO 42001 alignment.
ARCHITECTED
Resilience & Security
Operational Resilience Reference Architecture
Important business services → dependency mapping → impact tolerance → severe-but-plausible scenarios → recovery architecture. DORA / NIST / ISO 27001-aligned.
ARCHITECTED
Zero Trust Reference Architecture
Identity-centric perimeter, device trust, conditional access, micro-segmentation, continuous verification. Migration paths from legacy VPN estates.
DELIVERED
Security Logging Architecture
Sentinel + Splunk hybrid, KQL detection library, MITRE ATT&CK mapping, SOAR integration, tuned to reduce noise while preserving evidence.
DELIVERED
How to use these patterns
Each pattern is a starting point — a documented set of decisions made under specific conditions with known trade-offs. The right architecture for a specific engagement always requires re-evaluation of business context, constraints, existing estate and organisational maturity.
The intellectual property here is not the diagrams alone — it is the rationale behind each decision, the alternatives considered and rejected, and the operating experience of running these architectures at scale in regulated environments.
