Cloud migration and modernization on AWS, Azure and Google Cloud
We move workloads in dependency order, modernize the ones that need it and build security in from the first resource. Your team gets the infrastructure code, runbooks and monitoring at the end.
Why cloud migrations disappoint
Lift-and-shift without redesign
Applications built for a data centre move as they are. You pay cloud prices without getting the scaling or resilience you expected.
Applications left behind
Workloads move but still talk to each other through flat files, legacy routes and manual steps. They have been relocated, not modernized.
Security added after go-live
Identity, network segmentation and compliance evidence get pushed to a later phase. The remediation work then costs more than doing it during the build.
No plan for day two
The migration team leaves at go-live. Nobody has runbooks, a monitoring baseline or on-call procedures, and only the vendor understands the infrastructure code.
Five parts of a cloud program, planned together
Every workload has a migration approach and a tested rollback plan before cutover.
Cloud environments
- Landing zones on AWS, Azure or Google Cloud
- Infrastructure as code with Terraform or Pulumi
- Cost tagging, budgets and FinOps reviews
You getA cloud platform you can reproduce, audit and cost-manage.
Migration and modernization
- Rehost, replatform or refactor decided per workload
- Containers and managed services where they pay off
- Parallel running and validated cutover
You getWorkloads running in the cloud with a rollback plan for each move.
Identity and compliance
- IAM, role-based access and network segmentation
- Cloud security posture monitoring
- Compliance evidence collected from the first deployment
You getSecurity controls in place on day one, not added after an audit finding.
Hybrid networking and APIs
- VPN, ExpressRoute and Direct Connect links
- API gateways between cloud and on-premises systems
- Event-driven integration for migrated workloads
You getCloud and on-premises systems that keep working together after the move.
Deployment and monitoring
- CI/CD pipelines and release automation
- Monitoring, alerting and on-call runbooks
- Rightsizing reviews after go-live
You getAn environment your team can run, extend and troubleshoot on its own.
What each team gets from it
CIOs and IT leaders
An architecture signed off before any migration starts, a wave plan with dates you approve, and infrastructure code handed over at the end.
Infrastructure and engineering teams
Migration sequenced by dependency, rollback procedures tested before cutover, and every resource defined in code your team can read.
Finance and security
Cost tagging and budget alerts from the first resource, plus identity and compliance controls built during the migration, not after it.
Common questions
Which clouds do you work with?
AWS, Microsoft Azure and Google Cloud, including hybrid setups that keep some systems on-premises.
Should we lift-and-shift or refactor?
It depends on the workload. We assess each application and recommend rehost, replatform or refactor based on its dependencies, cost and how long you plan to keep it.
How do you avoid downtime during cutover?
We run old and new environments in parallel where possible, validate data before switching, and test a rollback procedure for every workload before it moves.
Can you run the environment after migration?
We can support it for an agreed period, but the goal is that your team can operate it. Runbooks, monitoring configuration and infrastructure code are all handed over.
Moving core banking off the mainframe, one domain at a time
A bank runs payments, accounts and lending on a mainframe that cannot support the APIs its digital products and regulatory reporting now need. A single cutover is out of the question because the system cannot go down.

A pharmaceutical company wants to move quality and manufacturing systems to the cloud. An earlier attempt copied on-premise controls into the cloud and left an expensive hybrid that satisfied neither IT nor quality assurance.
