High-Level Architecture

  1. 1

    Control Plane

    Policies, roles, versions, lifecycle states, and approvals govern the production surface.

  2. 2

    Multi-Agent Execution

    Supervisor and worker agents execute workflow steps across systems and data sources.

  3. 3

    Knowledge and Memory

    Hybrid retrieval, knowledge graph, and tiered memory provide enterprise context.

  4. 4

    Human Governance

    Approval gates, confidence thresholds, and reviewer queues preserve operational authority.

  5. 5

    Observability and Audit

    Traces, validation records, cost, latency, and quality signals remain available for review.

Data Flows

  1. 1

    Workflow execution request

    A user triggers a workflow; the control plane authenticates and policy-checks; the execution plane instantiates agents; retrievals and tool calls run with audit; Haluvance enforces each action; observability persists the full trace.

  2. 2

    Document ingestion event

    A source update is fetched, cleaned, classified, redacted, embedded, indexed, access-tagged, baselined by Haluvance, and logged.

  3. 3

    Prompt promotion

    A draft prompt is reviewed against test cases and Haluvance enforcement checks, approved under policy, promoted, routed to production traffic, and logged with diff and approver identity.

Security Architecture

Identity
Enterprise IdP integration via SAML or OIDC with MFA for admin and privileged access.
Encryption
AES-256 at rest, TLS 1.2+ in transit, per-tenant keys, rotation, and cloud or customer-managed KMS.
Secrets
Provider credentials and integration keys are stored in vaults with rotation policies.
Network
Private subnet deployment, perimeter protection, mTLS between services, and segmentation across control, execution, and data planes.
Isolation
Tenant-level isolation across data, queries, logs, execution, and resource quotas.
Application security
Input sanitisation, prompt-injection guardrails, rate limits, idempotent write APIs, scanning, and penetration testing.
Deployment and Reliability

SaaS
Hosted by Nexoraa with per-tenant isolation and regional residency.
Private cloud
Deployed in the customer's AWS, Azure, or GCP account.
Hybrid
Control plane and execution or knowledge layers can be separated across environments.
On-premise
Full deployment within the customer's data centre.
Air-gapped
Disconnected deployment with local model serving and approved update bundles.
Reliability
High availability, autoscaling, disaster recovery, backups, blue-green/canary releases, and automated rollback.
Integration Approach

High availability
Active-active or active-passive clustering for stateless services with no single point of failure for app, database, vector store, or queue.
Auto-scaling
Horizontal scaling on CPU, memory, queue depth, and token throughput. Inference, API, and worker tiers scale independently.
Disaster recovery
Cross-AZ replication with cross-region option, defined RPO/RTO per tier, and documented DR runbooks.
Backup and restore
Automated daily backups with point-in-time recovery and tested restore drills.
Deployment
Blue-green and canary strategies, zero-downtime deployments, and automated rollback on failed health checks.
