SOVEREIGN SYSTEMS & AI

Systems your organization can operate.

Design and integrate the data, identity, applications and infrastructure your organization depends on. Make authority, interfaces and operational ownership explicit.

FROM EXISTING ESTATE TO TARGET ARCHITECTURE

Build around the work. Not around a vendor.

Begin with critical workflows and constraints. Preserve useful systems where appropriate, and document the dependencies of anything introduced.

Target architectureExplore the perimeter

Within this scope

Data foundations

Connect approved repositories and databases, define access and retention, and preserve lineage across transformations.

Within this scope

Identity & interfaces

Integrate enterprise identity, service accounts and APIs with explicit permissions and ownership.

Within this scope

Applications & workflows

Build operational interfaces and controlled automations around the way teams work, including review and exception handling.

Within this scope

Private AI

Introduce model serving and knowledge retrieval where they solve a defined need.

Explore the AI infrastructure
Illustrative map. Scope, responsibilities and controls are agreed for each engagement.

REFERENCE ARCHITECTURE

Every layer has an owner.

The AI stack below illustrates one part of a sovereign information system. Its dependencies must connect to the wider identity, data and operational architecture.

YOUR APPROVED ENVIRONMENT

Models & serving

Run the model and control its version.

  • Open-weight models
  • Inference endpoints
  • Model versioning

Knowledge & data

Provide the business context it is allowed to use.

  • Document stores
  • Databases
  • Search & retrieval

Identity & control

Decide who and what can access each capability.

  • Enterprise identity
  • Access policies
  • Human approvals

Infrastructure & operations

Keep the environment available and recoverable.

  • Compute & storage
  • Network boundaries
  • Monitoring & recovery
Connected layers, with explicit access policies and a named operational owner.

DELIVERY & TRANSFER

Operational readiness is part of delivery.

Acceptance is not only a working interface. Define what the receiving team needs to maintain, recover and evolve the system.

Technical artifacts

Agreed code, infrastructure definitions, interface specifications and architecture decisions.

Validation evidence

Functional and security test records for the agreed scope, including limitations and unresolved risks.

Operating procedures

Monitoring, release, rollback, backup, restoration and incident escalation.

Ownership terms

Explicit licensing, access, repository and maintenance arrangements, including third-party constraints.
