Shared Platforms and Patterns So Every Pilot Does Not Reinvent Security
Halkwinds designs enterprise AI architecture — reference patterns for LLM/RAG, ML platforms, data access, security, and cost control — so business units build on common foundations instead of a sprawl of one-off pilots.
At a glance
What is Enterprise AI Architecture Services?
Halkwinds designs enterprise AI architecture — reference patterns for LLM/RAG, ML platforms, data access, security, and cost control — so business units build on common foundations instead of a sprawl of one-off pilots.
- Current-State Architecture Discovery. Inventory pilots, platforms, data paths, and security exceptions across business units.
- Target Reference Architecture. Define shared capabilities, boundaries, and non-negotiable controls with architecture and security leads.
- Decision Records and Standards. Capture ADRs for gateway, RAG, ML serving, logging, and build-vs-buy so teams stop re-debating defaults.
- Integration and Data Patterns. Specify how AI services access systems of record and governed data products safely.
Enterprise Challenges
Challenges We Solve
Pilot Sprawl Without a Shared Platform
Every team picks its own vector DB, gateway, and logging approach — multiplying cost, security review load, and integration debt.
Security and Data Access Retrofit
AI apps are built first and security-reviewed later, forcing rework when identity, DLP, and residency requirements finally appear.
Unclear Build-vs-Buy Boundaries
Enterprises buy overlapping AI SaaS while also building internal platforms, with no architecture decision records explaining why.
Latency and Cost Surprises at Scale
PoCs ignore token economics, retrieval costs, and GPU capacity planning — budgets blow up at the first successful adoption wave.
Integration With Systems of Record Untouched
Architecture diagrams stop at the model; CRM, ERP, and core systems remain manual bridges that kill production value.
No Reference Patterns for RAG, Agents, and Classical ML
Teams reinvent grounding, tool-calling, and batch scoring patterns without shared standards for observability and evaluation.
What We Deliver
Core Capabilities
Enterprise AI Reference Architectures
Blueprints covering LLM gateways, RAG, classical ML serving, and event-driven scoring on your cloud standards.
Platform Capability Mapping
Decide what belongs in a shared AI platform versus product-team responsibility — with clear interfaces.
Secure Data Access Patterns
Identity-aware retrieval, row/column controls, and residency patterns so models only see what policy allows.
LLM Gateway and Policy Enforcement
Central routing, budget controls, logging, and prohibited-use enforcement across business-unit applications.
Integration Architecture for Systems of Record
API, event, and batch patterns that connect AI decisions to CRM, ERP, service, and industry cores.
Observability and Evaluation Standards
Shared tracing, quality evaluation, and incident practices across generative and classical AI services.
Cost and Capacity Architecture
Token, retrieval, and GPU/capacity models with FinOps hooks before adoption scales spend unexpectedly.
Architecture Decision Records and Roadmaps
ADRs and phased roadmaps that engineering, security, and business sponsors can execute without re-litigating basics.
Enterprise Use Cases
In Production
Global Insurer AI Platform Consolidation
Challenge
Insurer had seven business-unit LLM experiments on different clouds with duplicated security exceptions and no shared logging.
Solution
Defined a shared AI platform reference architecture — gateway, identity, RAG services, and observability — with migration waves per BU.
Outcome
New AI apps reused the platform within one quarter. Security review cycle time fell from weeks to days for standard patterns.
Bank RAG Reference Pattern
Challenge
Retail bank's knowledge assistants were each implementing retrieval differently; compliance could not compare controls.
Solution
Standardised RAG reference architecture with citation, abstention, and access-tier patterns mandatory for internal assistants.
Outcome
Three assistants migrated to the pattern. Audit sampling became consistent across channels.
Manufacturer Hybrid Edge/Cloud AI Design
Challenge
Industrial group needed plant-edge inference and central model training without flattening OT security zones.
Solution
Hybrid architecture with edge serving, controlled promotion of models from central MLOps, and zone-aware data brokering.
Outcome
Architecture approved by OT security. First two plants deployed without exception-heavy networking.
SaaS Multi-Tenant AI Isolation Design
Challenge
B2B SaaS vendor embedding AI features risked cross-tenant data leakage in retrieval and prompt logs.
Solution
Multi-tenant AI architecture with strict tenant isolation in indexes, logs, and key management, plus per-tenant budget controls.
Outcome
Enterprise security reviews cleared isolation design. AI feature attach rate rose after blocked deals unblocked.
Healthcare System AI Integration Backbone
Challenge
Health system AI projects each negotiated separate EHR and identity integrations, creating delivery gridlock.
Solution
Shared integration patterns for FHIR/API access, identity propagation, and audit logging reused by clinical and ops AI teams.
Outcome
Average integration lead time cut roughly in half for subsequent AI use cases on the standard path.
Enterprise Token Cost Control Architecture
Challenge
Conglomerate's ungoverned API keys drove unpredictable LLM spend across shadow projects.
Solution
Central gateway with chargeback tags, rate limits, model-tier routing, and department budgets.
Outcome
Spend visibility within two weeks. Run-rate reduced ~35% by routing appropriate traffic to smaller models.
Industry Applications
Across Sectors
Financial Services
AI platforms with MRM-friendly logging, identity-aware retrieval, and core-system integration patterns.
Healthcare
Architectures respecting PHI boundaries, EHR integration, and clinical versus ops separation.
Insurance
Shared patterns for claims, underwriting, and customer AI across business units.
Manufacturing
Hybrid edge/cloud designs that satisfy OT security while enabling central learning.
SaaS and Technology
Multi-tenant AI architectures with isolation, metering, and enterprise procurement readiness.
Public Sector and Regulated Enterprises
Residency, audit, and procurement-aligned reference architectures for constrained environments.

FAQ
Common Questions
Architecture decides which capabilities are shared, which are federated, and how security/cost/integration work — whether you build, buy, or blend. A vendor platform can be a component; it is not a substitute for decision records and integration design.
Most enterprises get a usable target architecture, ADRs, and roadmap in 6–12 weeks. Deeper multi-region or OT-hybrid designs may extend with additional discovery.
Typical engagements range from $80,000 to $200,000 depending on business-unit count and regulatory depth. Implementation of the platform itself is scoped as follow-on engineering.
No. We design for your cloud strategy and often include model-router patterns so teams can change providers without rewriting every app.
Architecture defines the technical backbone; MLOps implements lifecycle tooling on it; governance sets risk policy. Mature programmes align all three — we show the seams clearly so owners are unambiguous.
Deliverables include reference diagrams, ADRs, interface contracts, and usually a thin reference implementation path — not slideware that cannot survive contact with engineering.
If strategy and use-case priority are unclear, start with an AI readiness assessment. If pilots already sprawl and security is blocking scale, architecture is often the right next engagement.
Yes. Token routing, caching, retrieval design, and GPU capacity planning are part of the architecture — especially when spend is already surprising finance.
We inventory them, map risk, and either bring them onto approved patterns or retire them with an alternative path — coordinated with security and procurement.
Good architecture standardises the boring, risky layers (identity, logging, gateways) and leaves product teams free on UX and domain logic. Autonomy without shared controls is what creates sprawl.
Yes. Mutual NDA is standard; multi-BU programmes often add data-sharing protocols so discovery does not leak competitive internals between units.
