Move to Open Source
“Our licensing costs are out of control and we're locked in”
Proprietary software stacks. Windows Server, .NET Framework, SQL Server, commercial middleware. Licensing costs climb every renewal. You're paying for flexibility you don't have.

Your applications run on open-source stacks on AWS. No vendor lock-in.
Applications running on Linux, .NET on open-source runtimes, and managed AWS services. No licensing surprises. Graviton instances cutting compute costs further.
Licensing costs have a way of creeping up. What started as a predictable line item becomes a growing tax on your business. One that increases every renewal cycle while delivering the same functionality you had last year.
You’re locked into proprietary stacks not because they’re the best tool for the job, but because migrating away feels too risky and too complex. So you keep paying.
Why licence debt compounds
The real cost of proprietary software isn’t just the licence fee. It’s the constraint.
You can’t choose your operating system. You can’t run on the most cost-effective compute. You can’t adopt managed services that would eliminate operational overhead. Because your application is welded to a specific runtime, a specific OS, a specific vendor’s ecosystem.
Every year you stay, the switching cost grows. Dependencies accumulate. Team skills narrow around a single vendor’s tooling. The lock-in isn’t a moment. It’s a gradient, and you’re further along it than you think.
How we do it
We don’t rip and replace. We assess, plan, and migrate in stages. So production is never at risk and your team is never overwhelmed.
Compatibility-first assessment. Every application gets analysed for portability. We identify what moves cleanly to .NET 8+ on Linux, what needs targeted rework, and what’s better replaced by a managed AWS service like RDS or ElastiCache. You get a clear picture before any work begins.
Graviton where it counts. AWS Graviton instances deliver better price-performance than x86 for most workloads. Once you’re on Linux, you’re free to use them. Cutting compute costs by up to 40% with no application changes.
Knowledge transfer, not dependency. Your team learns the new stack as we build it. Runbooks, monitoring dashboards, and deployment pipelines are all documented and handed over. You’re not swapping one vendor dependency for another.
What's usually in the way
-
Legacy .NET Framework dependencies won't port cleanly
Your applications were built on .NET Framework with Windows-specific dependencies. COM objects, Windows Auth, WCF services. Not everything moves to .NET 8+ without rework.
-
Team has no Linux operations experience
Your operations team has spent years managing Windows Server. Linux is a different world. Different tooling, different troubleshooting, different instincts. You can't retrain overnight.
-
Risk of breaking production during transition
These aren't greenfield applications. They're running production workloads with real users. A botched transition means downtime, data risk, and a team that loses confidence in the whole initiative.
What we resolve
-
Compatibility assessment before anything moves
We analyse every dependency. What ports cleanly to .NET 8+ on Linux, what needs rework, and what's better served by a managed AWS alternative. No surprises mid-migration.
-
Training and runbooks for Linux-based operations
Your team gets hands-on training and documented runbooks for the new stack. Monitoring, deployments, troubleshooting. All covered before you go live.
-
Staged migration with parallel running
Old and new stacks run side by side until validated. Each workload migrates independently with rollback procedures. Production is never at risk.
