ACI Infotech Powers Enterprise Cloud Modernization with Proven Excellence

The customer is a Fortune 500 healthcare and well-being company that enables access to care through an extensive network of over 1 million physicians and healthcare professionals, along with approximately 6,500 hospitals and numerous additional care facilities.

As the organization began modernizing its IT landscape to improve care access, reduce costs, and accelerate delivery, it encountered several structural and technical barriers.

Some of the key challenges encountered by the client include:

Aged, end-of-life infrastructure that slowed transformation planning and execution

Poorly documented legacy applications that complicated discovery and assessment

Multiple vendors and providers creating coordination challenges under tight timelines

To overcome the above challenges that impeded its modernization plans, the client evaluated multiple vendors before selecting ACI Infotech to lead the transformation. Thus, ACI partnered with Microsoft to combine the strengths of both organizations and execute a structured, large-scale modernization program.

The joint solution approach was delivered in four streamlined phases:

Phase 1 – Discovery & Assessment: Assessed ~12,000 servers and about 500 applications to understand dependencies, risks, and migration readiness.

Phase 2 – Azure Foundation Setup: Established a secure Azure environment within 6–8 weeks and defined a transformation roadmap using Infrastructure as Code (IaC).

Phase 3 – Migration Planning: Organized workloads into logical groups, created migration waves, and prepared execution strategies.

Phase 4 – Migration & Transformation: Executed migrations and decommissioned end-of-life infrastructure to complete the modernization journey.

Following the successful modernization initiative, the client realized significant gains in cost efficiency, migration quality, and operational stability.

Some of the key benefits accrued by the client include:

Migration of 85% workloads to Azure through rehosting and transformation

30–35% reduction in monthly infrastructure costs

$3M+ annual savings from retiring legacy on-prem infrastructure

100% automated validation coverage for consistent deployment accuracy

Zero migration defects and zero business disruption, ensuring seamless transition
