Built to Last: Flatiron Software Earns the AWS Migration and Modernization Competency

Flatiron is an AWS partner, and we recently earned AWS's Migration and Modernization Competency. It is a designation AWS gives to a select group of partners, after reviewing their actual client work and confirming it holds up against AWS's own standard.

How companies build and run software has changed fast. Managed services changed how much a team can run on its own. Customer expectations changed what counts as working, from good enough to always on. AI changed what companies want their software to do, and those features need a modern foundation to run on. Earning this Competency now matters because the companies facing that change need partners who actually understand it.

Good Migration, Bad Migration

Every company eventually runs into the limits of software it built years ago. A system that once fit the business starts to slow it down. It strains under growth, costs more to run than it should, and makes each new feature harder to add than the last. Migration and modernization is the work of fixing that. Migration moves a system onto modern infrastructure. Modernization rebuilds it to work the way current software should, so it scales, recovers, and stays secure on its own.

The value of that work lies in what the system can do afterward, and the difficulty lies in getting there while the business that depends on the system keeps running. A migration done well gives a company room to grow and a foundation for what comes next, including AI. A migration done badly moves the same problems to a new place at real cost. The difference between those two outcomes is the quality of the work itself, and that quality is hard to judge from the outside.

The Case for AWS

AWS suits this work because the hardest parts of a good migration come closer to standard on the platform. Databases scale with demand, encryption and access controls are built in, and recovery is handled by the services themselves. A modernization project starts on a foundation designed for scale and security.

The partnership goes further than the technology. Flatiron's engineers design alongside AWS specialists, which keeps each build aligned with current best practice and surfaces the right decisions early. AWS migration and modernization funding lowers the cost of the move for the client, and AWS account teams join through co-sell. For a client, a large one-time project becomes a phased, funded, lower-risk decision.

Two Kinds of Proof

Earning the Competency took two forms of proof.

The first was case study validation. Flatiron presented real client engagements with documented business outcomes: the state of each system before, the work delivered, and the result the client can measure. AWS reviewed these for substance, tracing each outcome back to the decisions that produced it.

The second was technical validation. AWS engineers examined how Flatiron's systems are actually built, across several projects. They confirmed that infrastructure is written as code and rebuilds cleanly, that access is scoped and credentials are short-lived, that data is encrypted and its keys governed, that releases are peer-reviewed and tested automatically, and that each system holds to defined performance targets under load. Clearing that review across multiple engagements shows this is how Flatiron builds every time.

The Work Behind It

1. Snapshot AI. Flatiron built its own performance-intelligence platform on AWS from the first line of code. It pulls data from nine engineering tools and turns it into clear, AI-generated insight for engineering leaders. When adoption reached large organizations, the early data pipelines buckled under the volume, so Flatiron rebuilt them on a managed orchestration service and restored reliability at scale. The platform now runs in production for internal and external teams.
2. A payments platform. The application had outgrown the single server it ran on. Flatiron rebuilt it on managed containers, with a database that scales on demand and global content delivery. Capacity now follows transaction volume, the team's operational load dropped sharply, and the cost tracks real usage.
3. An energy-technology platform. A legacy portal held the company to manual processes and a fixed server footprint. Flatiron re-architected it on managed containers and an on-demand database, with automated background jobs and caching for speed. Manual effort fell, data grew more accurate, and the platform gained the room to expand into Germany. Full case study on request.
4. A managed SaaS platform. The product ran as a single monolith, which slowed every release. Flatiron rebuilt it into services that deploy independently, on an on-demand database with edge delivery. Releases grew safer, scaling grew easier, and the cost of running it came down.

What It Means for Your Next Move

For any organization planning a migration, the useful question is the one that stays hidden the longest: will the system that emerges hold up. The AWS Migration and Modernization Competency answers it in advance. The part of the work a client would find hardest to check has already been checked, by AWS's own engineers, against the standard AWS holds for the discipline.

Flatiron holds that Competency because building for the far side of a migration is how it works by default. For a team weighing a move, that is the difference between hiring a vendor who can relocate a workload and a partner whose result AWS has already verified will stand.
