Verbaco™ Infrastructure Overview

The Verbaco™ infrastructure is designed for reliability, security, and flexibility, providing a robust foundation for deploying intelligent AI chatbots at enterprise and public sector scale. Built on Microsoft Azure, the platform leverages cloud-native components to deliver performance, control, and compliance across all layers of the solution.

Azure-Native, Secure by Default

Verbaco™ is hosted entirely on Microsoft Azure, taking full advantage of platform-level security and scalability features. Our Kubernetes-based architecture enables dynamic scaling of AI services, while maintaining strict control over ingress, authentication, and data flow.

  • Azure Kubernetes Service (AKS)
    Provides resilient container orchestration with automated scaling, patching, and availability zone redundancy.
  • Azure API Management (APIM)
    Acts as the secure gateway for all chatbot and system traffic. APIM enforces policies around authentication, rate limiting, version control, and throttling.
  • Azure Key Vault
    All secrets, API tokens, and encryption keys are securely stored and accessed via managed identities.
  • Azure Monitor and Log Analytics
    Integrated observability tools track application performance, user interactions, and infrastructure health.

Scalable and Modular Architecture

The Verbaco infrastructure is modular by design, allowing organisations to deploy only the components they need, while maintaining interoperability with existing systems.

  • Containerised AI Services
    Each chatbot agent, NLP component, and retrieval module runs in its own container. This ensures clean separation, independent scaling, and fault tolerance.
  • Workflow Engine on n8n
    The orchestration layer uses n8n to manage API workflows, data processing, and conditional logic, all running as stateless services within the Kubernetes cluster.
  • Horizontal Scaling
    Verbaco can scale individual pods for chat, document parsing, API calls, or translation, ensuring consistent performance under load.
  • Custom Domains and TLS
    Full support for subdomains, DNS management, and custom TLS certificates via cert-manager and DigiCert integration.

Network Security and Ingress Control

We enforce a zero-trust network model across the platform:

  • All ingress traffic is routed via a secure NGINX ingress controller with TLS 1.3 encryption
  • Only whitelisted APIs are exposed externally via APIM
  • Internal services are isolated at the namespace and network policy level
  • Outbound calls are restricted by egress policies and IP filtering

High Availability and Failover

  • Multi-zone AKS deployment ensures resilience to datacentre-level failures
  • Health probes and auto-restarts keep services running with minimal downtime
  • Node auto-scaling allows the cluster to grow based on workload and memory thresholds
  • Optional geographic redundancy across UK South, UK West, or North Europe

Deployment Options

Verbaco supports several flexible deployment models depending on organisational requirements:

  • Public Cloud (Azure-hosted SaaS)
    Fastest to deploy, maintained and secured by the Verbaco team.
  • Private Cloud / VNet-Integrated
    Deployed within your Azure subscription with private endpoints and internal routing.
  • On-Premise or Air-Gapped
    For defence, finance, or critical infrastructure, offline builds available on request.

Operations and Maintenance

  • CI/CD pipelines for rapid and safe updates
  • Infrastructure as Code using Terraform or Bicep
  • RBAC for DevOps teams with scoped cluster access
  • Optional 24/7 managed support and SLA-backed uptime guarantees

Compliance and Assurance

  • Infrastructure aligned with NCSC Cloud Security Principles
  • Full support for GDPR, ISO/IEC 27001, and UK data residency
  • Regular vulnerability scanning and patch management
  • Audit logs stored in immutable formats for regulatory review
