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
