CASE STUDY — CLOUD / HEALTHCARE

70+ applications moved to Azure — with 99.99% uptime.

A $27B integrated health system was carrying decades of on-premise complexity: mismatched app architectures, security gaps, and redundant systems. CiberSQL planned and executed a full migration to Azure — app by app, workload by workload — on a secure, governed foundation built to scale.

The challenge

Decades of on-premise sprawl.

A health system this size doesn’t run on one clean stack — it runs on hundreds of systems accumulated over years, each with its own quirks and risks.
  • Diverse complexity
70+ apps spanning wildly different architectures, ages, and dependencies.
  • Security gaps
Inconsistent controls and exposure across legacy infrastructure.
  • Redundant systems
Overlapping tools doing the same job, inflating cost and maintenance.
  • Legacy constraints
Aging platforms that resisted scaling and slowed new deployments.
  • Legacy constraints
Aging platforms that resisted scaling and slowed new deployments.
  • Compliance pressure
Healthcare data demands governance that ad-hoc environments couldn’t guarantee.
  • Uptime stakes
Critical clinical and member apps that simply couldn’t afford downtime.

The approach

Right strategy per workload — not one-size-fits-all.

Every application got assessed on its own merits. Some moved as-is; others were reworked to earn their place in the cloud.

Strategy 01

Lift & Shift

Stable, cloud-ready workloads moved to Azure as-is for a fast, low-risk win.

Strategy 02

Refactor

Light code and config changes to fit managed services and cut overhead.

Strategy 03

Rearchitect

Reshaped apps for scale and resilience where the old design held them back.

Strategy 04

Rebuild

Rebuilt from the ground up when legacy tech was past its useful life.

The foundation

A secure, governed landing zone.

Before workloads moved, we stood up the Azure foundation everything would land on — designed for security and compliance from day one.

Tenants & Landing Zones

Structured Azure tenants and landing zones as the governed base for every workload.

WAF & VNETs

Web Application Firewall and virtual networks isolating and protecting traffic.

Microsoft Entra ID

Centralized identity and access across the migrated estate.

Policies & Monitoring

Azure Policy for guardrails, continuous monitoring for visibility and control.
