Move. Don't break.
From old servers to AWS or Google Cloud, with a rehearsed cutover.

Senior engineers
No juniors. No middlemen.

Fixed price
Overruns are on us.

Live in weeks
Weekly demos on staging.

You own the code
100% of the IP, day one.
Yarify migrates applications from on-prem servers, VPS hosting or legacy platforms to AWS or Google Cloud. We inventory what runs today, containerise the app, define the target in Terraform, rehearse the data migration and cut over with a rollback plan, usually with minutes of downtime or none. A defined migration gets one fixed written quote after an assessment. The cloud accounts are yours from day one.
A migration, in five pictures
-
Inventory
Everything that runs today
-
Containerise
Same build everywhere
-
Target in Terraform
Reviewed, repeatable
-
Rehearse data
Restore, verify, time it
-
Cut over
With a rollback plan
Where teams migrate from
-
On-prem servers
Hardware nearing end of life, a server room nobody wants to own, backups on tape.
-
VPS and shared hosting
One box doing everything, updated by hand, no staging and no autoscaling.
-
A platform you outgrew
A legacy PaaS or managed host whose bill grows faster than your traffic.
-
Cloud to cloud
AWS to Google Cloud or back, for credits, pricing, data residency or a parent company's standard.
Rehost, replatform or refactor?
Not every workload deserves a rewrite. We pick per component and write down why.
| Approach | What changes | When it fits |
|---|---|---|
| Rehost (lift and shift) | Same app on cloud VMs | Hard deadline, stable app, refactor later |
| Replatform | Containers, managed database, managed queues | Most web apps and APIs; the usual sweet spot |
| Refactor | Parts redesigned for cloud services | Scaling limits or costs that a move alone won't fix |
| Retire or replace | Switched off or swapped for SaaS | Internal tools nobody maintains |
These map to the common migration strategies (often called the 7 Rs) described in AWS and Google Cloud migration guidance.
How we run a cloud migration
-
Assessment · Weeks 1–2
Inventory of apps, data, dependencies, DNS, email and cron jobs. Written plan and fixed quote.
-
Build the target · Next
Containers, Terraform, networking, secrets and CI/CD in your new cloud account.
-
Rehearse · At least once
Copy production data to the new environment, test the app, time every step.
-
Cutover · Agreed date
A scheduled window, a written runbook, DNS switched, rollback ready.
-
Watch and decommission · After cutover
Monitoring through the first weeks, then the old servers are switched off.
What usually breaks in a migration
We check for these during the assessment, not on cutover night.
- Cron jobs and scripts nobody documented
- Hard-coded IP addresses and file paths
- Email sending that depended on the old server's reputation
- Files stored on local disk instead of object storage
- Database versions and extensions that differ in the managed service
- DNS TTLs left at a day, so rollback takes a day
One quote for the whole move.
After the assessment you get a written migration plan and one fixed quote for it. Optional follow-up work, like refactoring a component, is quoted separately before it starts. Your cloud accounts, your Terraform, your runbooks.
DevOps servicesQuestions buyers ask us
How long does a cloud migration take?
A single web application with one database often moves in a few weeks including the assessment and a rehearsal. Many services, large data volumes or compliance reviews take longer. The assessment gives you a dated plan before you commit.
Will there be downtime?
Usually minutes, sometimes none. Stateless parts can run in both places at once; the database is the hard part. We rehearse the data move, measure how long it takes and choose between a short maintenance window and replication with a near-instant switch.
AWS or Google Cloud?
Both are solid. We look at your team's experience, existing contracts and credits, managed services you need, and data-residency rules. If you have no preference, we recommend one with reasons. We work in either, in your own accounts.
Will the cloud be cheaper than our servers?
Not automatically. A lift and shift of oversized servers can cost more. Savings come from rightsizing, autoscaling, managed services that replace manual work, and switching off what nobody uses. We estimate monthly cloud cost in the plan, before you move.
Do we have to rewrite the application?
Rarely. Most apps move with containerisation and configuration changes: environment variables, object storage for files, a managed database. We refactor only components where a move alone won't fix a real problem, and quote that separately.
Can you migrate an app we didn't build?
Yes. Most migrations we do are of code someone else wrote. The assessment covers the codebase too, and if it needs fixing first we say so. See code audit and software rescue.
