How RVO Health Migrated Rally Health Technologies Without Disrupting 10,000 Daily Users

KEYSYS helped RVO Health migrate and integrate Rally Health's client-facing technologies after acquisition, moving a complex application stack onto RVO Health's infrastructure without disrupting service for thousands of daily users.

The challenge

RVO Health needed to migrate a critical healthcare application without disrupting users.

After acquiring Rally Health from Optum, RVO Health faced a major technical challenge. The company needed to move Rally Health's client-facing technologies from Optum's servers to RVO Health's infrastructure.

The Rally Health application had 10,000 daily users, so the migration had to be handled carefully. Service disruption would affect users depending on the platform and create risk during a high-stakes acquisition integration.

The business problem was not simply, "Can we move the application?"

It was: How do we migrate a complex healthcare technology stack onto new infrastructure while preserving availability, scalability, and user trust?

The workflow looked like this
Define the new infrastructureThe environment needed to be clearly configured, repeatable, and scalable.
Terraform
Configure application orchestrationThe Rally Health stack included 28 microservices and numerous cron jobs.
Kubernetes
Connect external dependenciesThe system needed integrations with databases, Kafka, RabbitMQ, Redis, S3, and DNS.
Complex
Automate deploymentsThe team needed consistent, repeatable deployment workflows with minimal downtime risk.
GitOps
Protect the user experience10,000 daily users needed a smooth transition with no service disruption.
Mission-critical

RVO Health did not need a lift-and-shift effort with fragile handoffs. They needed experienced DevOps engineering that could translate a complex acquired system into reliable, scalable infrastructure.

Why it mattered

Healthcare technology migrations require both speed and confidence.

Acquisition-driven migrations are difficult because the technical work is tied directly to business continuity. Systems need to move, ownership needs to transfer, infrastructure needs to be recreated, and users still expect the application to work.

For RVO Health, Rally Health's application supported 10,000 daily users. The migration needed to protect that experience while giving RVO Health a strong infrastructure foundation for the future.

"This was not just a server migration. It was an operational continuity challenge."

The solution

Senior DevOps support for Terraform, Kubernetes, and GitOps migration

RVO Health partnered with KEYSYS and brought in Senior DevOps Engineer Jimmy Harris to support the migration and integration of Rally Health technologies.

Jimmy's expertise in Terraform configuration, Kubernetes, and GitOps practices helped RVO Health recreate, configure, and manage the Rally Health application stack on its own infrastructure.

Instead of relying on manual infrastructure setup, KEYSYS helped implement a repeatable, modern DevOps foundation that supported the migration and future operations.

Key capabilities
  • Terraform configuration for scalable infrastructure management
  • Kubernetes cluster configuration for 28 microservices
  • Cron job configuration and operational scheduling
  • External resource integrations, including databases, Kafka, RabbitMQ, Redis, S3, and DNS
  • GitOps implementation using ArgoCD and Helm
  • Automated deployment workflows
  • Reduced downtime risk during migration
  • Scalable infrastructure foundation for future growth
How it works now

From acquired infrastructure to RVO-managed application operations

KEYSYS  ·  RVO Health Migration Workflow
Define infrastructure with Terraform

KEYSYS configured the new environment using Terraform so infrastructure components were clearly defined, managed, and scalable.

Configure Kubernetes orchestration

The Rally Health stack was configured across a Kubernetes cluster supporting 28 microservices, numerous cron jobs, and external service dependencies.

Automate deployments with GitOps

ArgoCD and Helm were used to automate deployment of the Rally Health stack, making updates more consistent and efficient.

Maintain application availability

The migration preserved service continuity for Rally Health's 10,000 daily users while moving the application to RVO Health's infrastructure.

What started as a complex acquisition migration became a stable, scalable application environment managed through modern DevOps practices.

The impact

RVO Health completed a successful migration without disrupting service

RVO Health successfully migrated the Rally Health application to its own servers without disrupting service for 10,000 daily users. The new infrastructure is managed with Terraform and Kubernetes, giving RVO Health a robust and scalable foundation to continue supporting its mission to make healthcare easier to access, understand, and afford.

Smooth migration
  • Rally Health technologies moved from Optum's servers to RVO Health infrastructure
  • 10,000 daily users continued using the application without disruption
Stronger infrastructure
  • Terraform created a clearer and more scalable infrastructure foundation
  • Kubernetes supported 28 microservices and critical application dependencies
Better deployment operations
  • ArgoCD and Helm automated stack deployment
  • GitOps practices created more consistent updates and reduced downtime risk
Before KEYSYS
Acquired technology running outside RVO Health infrastructure
  • Rally Health technologies needed to move from Optum's servers
  • The application supported 10,000 daily users
  • The stack included many microservices, cron jobs, and external integrations
  • Manual or inconsistent deployment practices could increase migration risk
  • RVO Health needed a reliable infrastructure foundation after acquisition
After KEYSYS
RVO-managed infrastructure with modern DevOps practices
  • Terraform defines and manages the new infrastructure environment
  • Kubernetes supports the 28-microservice Rally Health application stack
  • External dependencies connect across databases, Kafka, RabbitMQ, Redis, S3, and DNS
  • ArgoCD and Helm support automated GitOps deployment
  • RVO Health completed the migration without disrupting daily users
