Design, Build and Implementation of a Trust-as-a-Service Platform (TaaS) in Microsoft Azure

Challenge / Problem

Delivering secure, compliant trust services at global scale

  • Enforcing secure, compliant infrastructure across multiple Azure regions
  • Standardizing deployment of Vault, Keycloak, and CertManager without configuration drift
  • Providing centralized observability, metrics, and audit trails for distributed services
  • Managing complex lifecycles across many microservices and environments
  • Achieving latency-aware global routing with high availability and resilience
  • Minimizing manual operations while maintaining strict change control

Our Approach

Security, automation, and governance by design

  • Infrastructure-as-Code first with modular Terraform architecture
  • GitLab CI for planning, testing, security checks, and approvals
  • Hub-and-Spoke-Netzwerkarchitektur mit Azure Firewall, DDoS-Schutz und NSGs
  • Hub-and-spoke network architecture using Azure Firewall, DDoS protection, and NSGs
  • Zero Trust security model using RBAC, Managed Identities, and end-to-end TLS
  • Unified telemetry with Azure Monitor, Log Analytics, and Sensu
  • Policy-as-Code and tagging standards to enforce governance and cost transparency und Tagging-Standards zur Governance- und Kostenkontrolle

Implementation

Azure-native platform with GitOps and full observability

  • Cloud & Network
    Regional hub-and-spoke VNETs
    Azure Firewall, DDoS Protection, Traffic Manager, Load Balancers
  • Platform
    AKS with autoscaling, CSI drivers, and managed identity
    Helm-basierte Deployments
  • GitOps
    ArgoCD orchestrating Vault, Keycloak, CertManager, microservices, and tooling
  • Security
    Vault for secrets and audit logs
    Keycloak as Identity Provider
    Automated TLS via CertManager
  • Azure Monitor, Log Analytics, and Sensu
    Azure Monitor, Log Analytics und Sensu
    Logs, metrics, traces, and SLO-based alerts
  • Data Services & Governance
    Azure PostgreSQL Flexible Server
    Azure Policies, standardized modules, environment segregation

Results

A future-ready trust platform with measurable outcomes

  • Repeatable, compliant multi-region deployments with full auditability
  • Faster and safer releases through GitOps, versioned configs, and one-click rollbacks
  • Reduced MTTR via full-stack observability
  • Improved user experience through latency-aware global routing
  • Lower operational overhead due to automation and standardization
  • Lower operational overhead due to automation and standardization
  • Lower operational overhead due to automation and standardization
