Solution
Cloud migration
Moving to the cloud is not one job. Every system has its own best route, and some should not move at all. We inventory what you run, choose a route for each part, and move it in waves, with a tested way back.

At a glance
What we build
We plan and carry out the move of your servers, applications, and data from your own equipment or a hosting provider to a cloud platform, with a tested way back.
Problems we solve
Servers are costly, aging, or fragile, a data center contract is ending, or the business needs capacity and resilience it cannot easily build for itself.
Who we serve
Owners and technology leads whose systems run on their own servers or older hosting, and teams told to reduce risk or cost.
How to choose
Move what benefits first, in waves, with a way back at each step. Do not move everything the same way; some systems should be improved, replaced, or retired.
The problem
Why organizations move, and why moves go wrong
The reasons to move are practical. A data center contract ends. A server is old enough that nobody wants to restart it. A business needs to scale for a busy season, or to recover quickly after a failure, without buying equipment it will use for a few weeks a year.
Moves go wrong for equally practical reasons. Systems are moved without anyone knowing what depends on them. Costs are estimated from a brochure, not from how the system behaves. The cut-over date arrives, and there is no tested way back.
A sound migration treats the move as a series of small, reversible steps, each tested, with the cost modeled before it starts and watched after it ends.
How we solve it
What a cloud migration touches
Layers from top to bottom. Applications, supported by Move as they are; Improve for the cloud; Data, supported by Databases; Files and backups; Network and security, supported by Access and identity; Encryption and monitoring; Running it afterwards, supported by Cost and capacity.

Routes
Choosing a route for each system
Lift and shift
Suits
A system that works and must move quickly, such as before a contract ends.
- Trade-off
- Fast, but it brings old inefficiency with it, and the cloud bill can be higher than expected.
Move and tidy
Suits
A system where a small change, such as a managed database, removes a lot of upkeep.
- Trade-off
- A little more work now for much less to run later.
Rebuild for the cloud
Suits
A system that must scale or recover quickly, and whose design is holding it back.
- Trade-off
- The largest effort, with the largest long-term gain.
Replace with a service
Suits
A function such as email or file storage that a provider already does well.
- Trade-off
- You adapt to the service, and data must be moved with care.
Retire it
Suits
A system nobody uses any more.
- Trade-off
- Needs confirmation that nothing depends on it before it is switched off.
Which cloud
Which cloud suits you?
The three large providers are all capable. The choice usually follows the tools and skills you already have.
What best describes your estate?
Choose this when
Windows servers, Microsoft sign-in, and Microsoft business software.
- What you get
- A move to Azure, which connects closely to the tools you have.
- Keep in mind
- Licensing rules can reduce or raise the cost, so we check them first.
Choose this when
Varied workloads, and a wish for the largest ecosystem and hiring pool.
- What you get
- A move to AWS, with the broadest set of services.
- Keep in mind
- Breadth brings complexity, so cost and design need active care.
Choose this when
Analytics, machine learning, or a team already on Google tools.
- What you get
- A move to Google Cloud, strong in data and containers.
- Keep in mind
- Check that the services you need are offered in your regions.
Choose this when
A mixed estate, or a policy against single-provider reliance.
- What you get
- A design built on containers and open tools, so moving later is practical.
- Keep in mind
- Portability has a cost, so use it where it matters.
What you get
What a migration delivers
A plan
- An inventory and a route for every system.
- A cost model you can check against the bill.
A safe landing
- A secured cloud environment, built as code so it can be repeated.
- Access and monitoring in place before the first move.
A tested move
- Rehearsals before each cut-over and a rollback plan.
- Checks that data arrived complete and unchanged.
Control afterwards
- Budgets, alerts, and right-sizing reviews.
- Documentation and training, or ongoing care.
How we do it
A migration in waves
Inventory and map
We list every system, what it depends on, who uses it, and when it is busiest.
What it produces
- System inventory
- Dependency map
Choose the route and model the cost
Each system gets a route. The running cost is estimated from real usage, with a margin for error.
What it produces
- Route per system
- Cost model
Prepare the landing zone
Accounts, networks, access, and monitoring are set up first and tested, so the first system lands in a safe place.
What it produces
- Environment set-up
- Security review
Move in waves, with a way back
A low-risk system goes first as a pilot. Each wave is rehearsed, moved, checked, and either accepted or rolled back.
What it produces
- Rehearsal
- Cut-over plan
- Rollback plan
Tune and hand over
After the move we right-size resources, switch on cost alerts, and train your team to run it.
What it produces
- Cost report
- Runbook
Common questions
Questions about moving to the cloud
Will the cloud be cheaper?
Not automatically. It can be, especially when you stop paying for idle capacity or old equipment. It can also be dearer if systems are moved without being tuned. We model the cost first.
How much downtime should we expect?
For most systems, a short, planned window at cut-over, and sometimes none, where data can be kept in step beforehand. We agree the window with you.
Is the cloud less secure than our own servers?
Not if it is set up well. Large providers offer strong tools, but the set-up is yours to get right. We design access, encryption, and monitoring from the start.
What if we want to leave the cloud provider later?
We design to keep that option open where it is worth the cost: containers, open standards, and infrastructure written as code.
Can we move only part of what we run?
Yes, and many organizations do. A mixed estate is common, and we plan the connections between the parts.

Technical depth
How we build and move
Our engineering choices on infrastructure as code, containers, data movement, and security and cost, written for the people who will own the system after launch.
The target environment is written as code with Terraform, reviewed like any other change, and rebuilt from scratch in rehearsal. That makes the environment repeatable and auditable.
- Applications that suit it are packaged in Docker containers, and run on managed container services or on Kubernetes where scale demands it.
- Stateless parts are separated from data, so they can be replaced without loss.
- Databases are replicated to the target and kept in step until the cut-over, which keeps downtime short.
- Row counts, totals, and sampled records are compared before the old system is retired.
- Least-privilege access, network segmentation, encryption at rest and in transit, and central logging from day one.
- Tagging, budgets, and scheduled right-sizing keep cost attributable and controlled.
