Legacy & Cloud Modernization
Many businesses still run important work on systems built ten or twenty years ago. We help you move them to modern cloud infrastructure in planned stages, so your product stays available while the migration happens.
What this covers
A planned migration, one stage at a time
Each migration starts with a review of your current systems. From there we agree a plan with your team, including which parts move first and how each stage is tested.
Assessment and planning
We look at what you run today, what it costs and where the risks are, and agree the order of the migration with you.
Cloud migration
We move workloads to AWS and other providers, including regulated environments like AWS GovCloud.
Infrastructure cost reviews
We audit hosting setups to find wasted spend. One six-week audit cut a client's infrastructure bill from $500K to $250K a month.

Success stories from our clients
Load Testing Platform for 10M Concurrent Users
We built a modern load testing platform capable of simulating 10 million concurrent users while preserving 20 years of existing test investments.
Cutting a Game's $500K/Month Infrastructure Costs in Half
A 6-week infrastructure audit identified catastrophic cost leakage, enabling a financially doomed project to continue development.
AWS GovCloud Migration Under 7-Week Deadline
We migrated a simulation platform to AWS GovCloud IL5 in 7 weeks to maintain a Department of Defense contract, navigating security constraints and compressed timelines.
Frequently asked questions
Legacy and cloud modernization means moving important work off systems that are 10 to 20 years old and onto modern cloud infrastructure. Terminal Velocity does this in stages, so your product stays available throughout the migration.
Every project starts with a review of your current systems, costs and risks. From that we agree a plan with you that sets out what moves first and how each stage is tested before the next one begins. You know the order of work and the checks involved before anything changes.
We move workloads to AWS and other major cloud providers. That includes regulated environments such as AWS GovCloud, where we migrated a simulation platform to Impact Level 5 in seven weeks so the client could keep a US Department of Defense contract.
Yes. We audit hosting setups to find spend that isn't doing useful work, such as oversized or idle resources. In one six-week audit we cut a client's infrastructure bill from $500,000 to $250,000 a month, which let a project that had become too expensive to run keep going.
The staged approach is designed to keep your product running throughout. Each stage is tested before it goes live, and the older system keeps handling that part of the work until the new one is ready to take over.
It depends on how many systems are moving and how closely they connect. Our AWS GovCloud migration of five components took seven weeks. The assessment at the start of each project gives you a timeline before any work begins.
