Multi-Cloud / Hybrid / DevSecOps AWS Azure On-Premises

ITSM Company

DevOps Delivery for Multi-Cloud/Hybrid microservices on AWS FedRamp, Azure, and On-Premises.

Overview

Acting as a DevOps Delivery Engineer for a leading ITSM provider, I managed deployments and structural architectures for a massive distributed application spanning multiple cloud environments. The system consisted of 10+ interconnected microservices supporting a global user base, requiring strict compliance across AWS FedRamp, Azure, and legacy on-premises infrastructure with zero-downtime deployment capabilities.

Multi-Service Architecture

The ITSM platform comprised several critical services: AppServer (core API gateway), ChatService (real-time communications), WorkflowService (business process automation), IntegrationServer (external API connectors), Analytics Service (data intelligence), OpsConsole (operational dashboards), Data Archive (long-term data retention), Logging Service (centralized logging), Identity Server (authentication/authorization), and Teams Bot (enterprise integrations). Each service required independent scaling, monitoring, and deployment pipelines.

Environment Landscape

The deployment strategy encompassed multiple environment tiers: dedicated Development environments for rapid iteration, comprehensive Testing environments for QA validation, FedRamp-compliant Production environments on AWS, Azure production regions with multi-tier redundancy, Customer Zero environments for early feature validation, and on-premises legacy VMs supporting legacy .NET Framework applications. Each environment required isolated networking, separate CI/CD pipelines, and strict version management.

Key Responsibilities & Impact

  • Managed an intricate hybrid architecture spanning AWS FedRamp-certified infrastructure, Azure VMs (IaaS), Azure AKS (Kubernetes), and legacy On-Premises VMware clusters running .NET-based services.
  • Engineered sophisticated CI/CD pipelines using Azure DevOps with automated build, test, and multi-environment deployment orchestration for all 10+ microservices.
  • Integrated advanced Static Security Scans (Prisma Cloud, BlackDuck, Coverity) natively ingrained into CI/CD pipelines, enforcing container security hardening, vulnerability remediation, and SAST/DAST analysis before deployment.
  • Implemented rolling and blue-green deployment strategies ensuring zero-downtime updates with automatic rollback capabilities for mission-critical services.
  • Architected centralized monitoring using Grafana dashboards, Azure Log Analytics, and InfluxDB metrics for real-time visibility across all deployment targets.
  • Optimized traffic routing and latency between on-premise components and cloud databases via sophisticated networking solutions (AWS VPN, Azure ExpressRoute, hybrid cloud interconnects).
  • Developed on-premises deployment automation using InstallShield with merge modules for seamless upgrade and maintenance window procedures.
Result

Bridged the gap between modern container ecosystems and legacy infrastructure. Passed strict compliance and FedRamp audits, securing government-level deployments with 100% security SLA compliance.
