“Distil Stack understood that building a platform for aviation requires more than a conventional application. Their approach focused on translating a specialized business concept into a practical digital product, with careful attention to usability and the needs of different users.”
Cloud Architecture & Migration
Cloud architecture & migration services
We design secure landing zones and migrate applications and data in planned waves, so you end up with a platform that's cheaper to run and easier to change.
A custom engineering engagement
We scope this service around your workflow, existing systems and acceptance criteria. The work starts with the problem and its constraints, then a written scope and price. A packaged solution is a different buying route: choose it when its defined deliverables already fit the job.
01The problem
Where things usually stall
Well-architected cloud foundations and migrations planned wave by wave.
- 01
Lift-and-shift regret
Servers moved as-is cost more in the cloud than they did in the data centre.
- 02
Account sprawl
Dozens of accounts and projects with no consistent networking, identity or tagging.
- 03
Migration fear
Critical systems stay on ageing hardware because nobody wants to own the risk.
02Capabilities
What we deliver
- 01
Cloud readiness assessment
Application inventory, dependencies and a migration strategy for each workload.
- 02
Landing zone design
Accounts, networking, identity and guardrails set up as code.
- 03
Migration waves
Workloads grouped and moved in order, with testing and rollback for each wave.
- 04
Data migration
Database moves with replication, validation and short cut-over windows.
- 05
Hybrid and multi-cloud
Connectivity and governance across clouds and on-premise systems.
- 06
Architecture reviews
Well-architected reviews of existing platforms with a prioritised fix list.
03Outcomes
What changes once it’s live
- 01
A documented landing zone
Network boundaries, identity, logging and environment ownership defined in code.
- 02
A workload-specific migration
Each application gets a placement, dependency and cutover plan based on how it runs today.
- 03
A recovery route
Backup, restore and rollback assumptions are tested before the old environment is retired.
04Approach
How we deliver it
- 01
Inventory the workload
Map applications, data stores, traffic patterns and dependencies, including the links outside your cloud account.
- 02
Design the destination
Agree identity, network, resilience and cost constraints, then express the landing zone as code.
- 03
Rehearse the move
Test data transfer, application behaviour and recovery in a staging environment before production cutover.
- 04
Cut over with evidence
Reconcile data, monitor the agreed health checks and retain a usable rollback window before decommissioning.

06Case studies
Featured success stories
How long does a migration take?
A small estate can move in six to eight weeks. Larger portfolios run in waves over several months.
Should we containerise everything?
No. We containerise where it pays off and use managed services where they're simpler.
Can you help us choose a cloud provider?
Yes. We compare cost, services and team skills for your workloads and make a recommendation.
How is the engagement priced?
We agree a fixed scope and price after reviewing the work, system dependencies and acceptance criteria. The pricing guide explains approved ranges for the engagement types it covers. A written proposal confirms what is included before a build starts.
How should the first delivery decision be made?
Map applications, data stores, traffic patterns and dependencies, including the links outside your cloud account. Agree identity, network, resilience and cost constraints, then express the landing zone as code.
What should the acceptance criteria cover?
Network boundaries, identity, logging and environment ownership defined in code. Each application gets a placement, dependency and cutover plan based on how it runs today. Backup, restore and rollback assumptions are tested before the old environment is retired.
