Home Base 

Onity Group is a financial services company specializing in mortgage servicing and origination. Since 1988, it has served a customer base of homeowners, business clients, and investors. 

As the company was preparing to exit a legacy platform, it saw an opportunity to rethink its IT approach. Onity wasn’t looking for a shiny new version of the same old environment. Instead, it wanted a cost-effective operating model that would improve flexibility and lay the groundwork for future transformation. 

Cracks in the Foundation 

Rising costs, growing security concerns, and a fixed-node model were getting harder to work around. 

Cost and Complexity. The legacy platform came with unnecessary overhead. Onity hoped to shift its infrastructure toward a consumption-based model that would match actual usage. 

Operating Agility. Onity also wanted infrastructure that could scale dynamically. Simplifying operations would free up engineering teams to spend less time on maintenance and more time supporting new business functions. 

Future-Readiness. Onity’s old environment lacked flexibility. That made it hard to adopt and support modern AWS capabilities and pursue new initiatives like AI-driven experimentation, advanced data and analytics, and application modernization. 

Onity needed a fluid, pay-as-you-go approach. A project of this size also had to move fast, at meaningful scale, and all without disrupting the business. 

Building More Than a New Address 

This wasn’t just a migration in the narrow, technical sense. It was a broader IT transformation effort to help the company streamline operations and improve performance. So naturally, it required partners that could do more than just technical execution.  

AHEAD’s platform modernization expertise was vital in shaping and orchestrating the migration strategy. AWS provided the native cloud environment and services. Together, the teams turned Onity’s platform exit into an operating model shift. 

Phase 1 – Advise 

AHEAD put guardrails around a high-stakes migration from the very beginning, with only two migration weekends per month. 

Why the Groundwork Mattered: A controlled approach meant fewer disruptions, while maintaining the momentum a large project like this needed. 

Phase 2 – Build 

AHEAD and AWS rebuilt Onity’s environment as a multi-account AWS architecture, grounded in AWS Landing Zone principles, and aligned with the AWS Well-Architected Framework.  

The design was anchored by AWS-native services:  

• Amazon EC2: Compute foundation for migrated workloads 
• Amazon WorkSpaces: Stable, scalable desktop infrastructure 
• AWS Elastic Disaster Recovery: Strengthened resiliency and disaster recovery capabilities 

How It Came to Life: The new environment was flexible, efficient, and capable of supporting both enterprise-scale execution and business continuity. 

Phase 3 – Run 

The new model significantly improved cost transparency and simplified management. Its stable cloud foundation could support day-two operations and ongoing modernization efforts. 

How It Kept Delivering: Instead of a rigid, legacy environment, Onity now had an adaptable model that could keep pace with its business priorities. 

Same Business, Stronger Bones 

Working with AHEAD and AWS, Onity migrated 700+ servers to a modern AWS-native environment in record time and with zero rollbacks. 

More Room in the Budget. By eliminating legacy platform licensing and infrastructure overhead, Onity could better allocate resources and align spending to real demand. 

Steady Gains Over Time. The move to a consumption-based model also empowered the business case for incremental application modernization. Onity no longer had to wait each time for a large transformation project. It could now selectively rebuild and shift applications and adopt additional native cloud services where they made sense. 

Ready For What’s Next. Modern landing zone architecture and improved disaster recovery strengthened resilience and security. The broader AWS-native foundation also better prepared Onity for work in AI, data, and analytics. 

Faster to Adapt. The new environment made it easier to scale infrastructure up or down. Reduced platform complexity meant Onity could respond quickly to growth initiatives or acquisition activity (or the kind of market swings that don’t wait politely for IT roadmaps.) 

What’s Next 

Onity is now in a better position to scale with business demand, operate with greater flexibility, and pursue future initiatives without the limits of its previous environment. 

With AHEAD’s strategic guidance and AWS’s powerful cloud foundation, Onity elevated IT beyond infrastructure to enable growth, modernization, and the next wave of innovation.
