Infrastructure modernization
A multi-data-center environment moved to modular cloud services, with a zero-downtime cutover and 99.95% sustained uptime.

AWS cloud platform
Modular services
Independent deployment
01 · Challenge
Critical HR, finance, inventory, and mobile applications ran on a monolithic LAMP+ stack across multiple data centers. The migration needed to preserve service continuity while giving each business function room to scale and change independently.
02 · Approach
The environment was refactored into modular services on AWS EKS. Argo CD provided a repeatable deployment process. A parallel run validated the new environment under production load before the legacy systems were retired, with rollback preserved through the cutover.
03 · Results
For a manufacturer, the relevant lesson is how to modernize connected business systems while planning for continuity, validation, and recovery. The scope and migration sequence must reflect the systems your operation depends on.
The original environment included multiple databases, message queues, and search platforms. Kubernetes services separated the business functions, while GitOps with Argo CD made version-controlled changes the path to production. The source environment represented $5–6M in capital infrastructure; the resulting cloud spend was approximately $300K per year. These are different cost bases, not a measure of annual savings.
