Edenic Case Study
HomesUSA - Azure App Services → AKS modernization
Edenic delivered an end-to-end modernization program to migrate distributed Azure App Services and supporting workloads to a secure, scalable AKS platform across DEV, QA/STG, and PROD - with private networking, standardized CI/CD, and production-grade observability.

Scale
300+ Azure resources assessed
Apps

Context
Executive summary
A high-signal overview of the business and platform shift.
-HomesUSA ran a large Azure footprint with 300+ resources across App Services, SQL, Storage, Key Vault, App Insights, and networking components.
-The environment faced cost pressure, inconsistent deployments, and scaling constraints inherent to the existing PaaS model.
-Edenic delivered a phased migration to AKS, enabling containerized apps, secure identity, private networking, GitOps CD, and standardized CI.

Before
Core challenges
Why a platform-level reset was necessary.
-Rising infrastructure cost
-Operational overhead across a large distributed Azure footprint
-Lack of containerization and limited modernization
-Fragmented CI/CD pipelines
-Multi-environment inconsistencies
-Scalability limits with App Services
-Siloed configuration and secrets handling
Intent
Migration goals
The business outcomes mapped to technical bets.
-Reduce cloud spend
-Standardize deployments across DEV, QA/STG, and PROD
-Increase scalability and resiliency
-Implement best-practice identity and networking
-Improve observability and automation
-Establish CI with Azure DevOps and GitOps CD with ArgoCD
Platform model
Environment isolation
Each environment received a complete, independent AKS implementation to avoid cross-environment blast radius.
DEV
-Isolated AKS implementation
-Dedicated VNET, subnets, namespaces, config & Key Vault
-Separate pipeline triggers and ArgoCD project boundaries
QA / STAGE
-Pre-prod validation environment
-Independent network + private endpoints
-Environment-scoped DNS and configuration
PROD
-Private AKS cluster posture
-NAT gateway for controlled outbound
-Full production-grade monitoring with App Insights
Execution
Phased delivery
A structured migration plan designed to de-risk cutover, validate dependencies early, and enforce platform standards.
Phase 0 - Assessment, Discovery & Planning
-Discovery of ~300 Azure resources
-Dependency mapping across App Services, Functions, SQL, Storage, DNS, certificates, Key Vault usage
-Workload criticality and migration priority strategy
-Cutover and rollback plan
-Validated inventory and risk analysis
Phase 1 - AKS & Core Infrastructure Foundation
-Private AKS clusters per environment
-Azure CNI with separated system and workload node pools
-Linux + Windows pools for hybrid workloads
-VNET per environment with dedicated subnets
-VNET peering to VPN and production NAT gateway
-Private endpoints for AKS API, ACR, Key Vault, Storage
-Azure AD RBAC integration
-Workload Identity (OIDC) for pod-to-cloud auth
-Prometheus operator and Grafana dashboards across all env
-Production-grade validation evidence for DNS, ACR pulls, Key Vault CSI mounts, RBAC
Phase 2 - Application Refactoring & Containerization
-Dockerization of required .NET services
-Helm charts for all containerized apps
-Environment-specific values structure
-Liveness/readiness, resource limits, and HPA where applicable
-Azure DevOps CI builds and pushes images to ACR
-ArgoCD GitOps CD deploying Helm releases per environment
-Non-blocking documentation of apps not required for immediate cutover
Phase 3 - Databases & Security
-Full Azure SQL inventory by environment
-Environment-isolated AKS → DB access
-Private endpoint strategy prioritized for PROD
-Connection strings centralized in Key Vault
-PITR and backup posture validated
-DR recommendations and restore-drill guidance
Phase 4 - CI/CD, Security & Observability Hardening
-Standardized CI triggers for develop, release/*, hotfix/*, master
-GitOps guardrails to reduce manifest drift
-Pod security standards and network policies
-Ingress TLS enforcement and trusted registry posture
-Alerting for CPU/memory thresholds and failure patterns
Phase 5 - Testing, Validation & Production Deployment
-Functional testing of key services
-Ingress, routing, secret rotation, DNS checks
-Production cutover using GitOps promotion workflow
-Rollback readiness validated
-Post-deploy telemetry reviewed with stakeholders
Phase 6 - Documentation & Knowledge Transfer
-Deployment manuals and rollback procedures
-Incident response guidance
-Namespace and resource standards
-ArgoCD and Helm operational playbooks
-Hands-on training for platform and app onboarding
Outcome
What was delivered
High-level deliverables safe for public portfolio representation.
-Full modernization path from App Services to AKS with private cluster posture where required
-30+ services containerized and deployed for the migration-critical set
-CI with Azure DevOps and GitOps CD with ArgoCD established across environments
-Key Vault CSI + App Configuration standardized secret and config delivery
-Azure CNI networking with private endpoints and private DNS aligned to least-privilege design
-Prometheus/Grafana across all environments with production App Insights for deep visibility
Business impact
Value delivered
