Cutting 44% Azure Spend for a US Logistics Platform using AKS & Spot Instances

A real-time logistics tracking platform handling 80M daily IoT telemetry events saw their Azure monthly burn skyrocket to $45,200/mo. We completely restructured their compute topology into Azure Kubernetes Service with KEDA spot auto-scaling.

The Challenge & Technical Inefficiencies

The client operated 28 static standard D16s_v4 virtual machines running 24/7 to absorb peak morning delivery hours. Over 60% of CPU cycles were sitting idle between 8 PM and 5 AM. Furthermore, 42 unattached Premium SSD managed disks from decommissioned nodes were quietly racking up $3,800/mo in zombie billing.

Our Engineering Solution

  • • Containerization: Dockerized backend ingestion services and deployed on an Azure Kubernetes Service (AKS) cluster.
  • • Spot Instance Integration: Shifted non-critical telemetry queue consumers to Azure Spot node pools at an 82% discount, using graceful termination webhooks.
  • • KEDA Event-Driven Sizing: Configured Kubernetes Event-driven Autoscaling to scale pods based on Azure Service Bus queue depth rather than raw CPU spikes.
  • • 3-Year Savings Plan: Locked in a 3-Year Azure Savings Plan on baseline cluster nodes for an additional 38% compute discount.

Legacy SQL Server to Azure SQL Managed Instance Migration with Zero Data Loss

An enterprise European billing company was trapped on an aging on-premise SQL Server 2014 cluster approaching End of Support. We designed an online replication cutover to Azure SQL Managed Instance with 0 bytes of data loss.

The Challenge & Technical Risks

The client's 4.2 TB database handled financial transactions with strict regulatory audits. Any data loss or prolonged downtime during business hours would trigger six-figure SLA penalties. Schema migration had to support legacy SQL CLR objects and cross-database joins that standard Azure SQL Database couldn't run.

Our Engineering Solution

  • • Compatibility Assessment: Executed Microsoft Data Migration Assistant (DMA) to resolve 14 breaking T-SQL syntax deprecated statements before live data sync.
  • • Continuous Online Sync: Deployed Azure Database Migration Service (DMS) via secure IPSec VPN tunnel, streaming continuous transaction logs to Azure SQL Managed Instance.
  • • Shadow Read Testing: Pointed analytics and read queries to the replicated instance for 7 days to stress-test query plans under live production volume.
  • • 15-Minute Cutover Window: Performed clean final log cutover at 2:00 AM UTC on Sunday with total connection redirection taking 11 minutes.

Enterprise Multi-Region Landing Zone Architecture with Azure Hub-Spoke VNet

A fast-growing US SaaS company expanding into Europe suffered from unsegmented flat networking and uninspected internet egress. We architected a Microsoft Cloud Adoption Framework (CAF) Landing Zone codified 100% in Terraform.

The Challenge & Architectural Vulnerabilities

Engineers were manually creating VMs with public IPs directly attached. Database servers had public endpoints enabled, and development teams shared a single Azure subscription with no billing boundaries. An external penetration test identified critical gaps in network micro-segmentation and egress logging.

Our Engineering Solution

  • • Management Group Hierarchy: Structured Root → Platform → Workloads (Prod/Non-Prod) subscriptions with automated RBAC inheritance.
  • • Hub-Spoke VNet Topology: Centralized Hub VNet containing Azure Firewall Premium, Azure Bastion, and Private DNS Resolvers with zero public IP exposure on spoke workloads.
  • • Private Link Endpoints: All PaaS storage, Redis clusters, and SQL databases were routed exclusively via Azure Private Endpoints inside private subnets.
  • • Automated Guardrails: Implemented 32 Azure Policy definitions blocking any resource deployment that lacks customer-managed encryption or required cost tags.
