Cloud migration services

Cloud migration services for applications and databases still on your own servers or with a hosting provider: an assessment, a plan per workload and the move to Microsoft Azure, AWS or Google Cloud, with infrastructure as code, pipelines and monitoring in place on the day of cut-over.

What a cloud migration includes

  • Assessment per workload

    An inventory of servers, applications, databases and the dependencies between them, with a recommendation for each: rehost, replatform, refactor or retire, and the monthly cost of each option.

  • Landing zone as code

    Subscriptions or accounts, networking, identity and policies declared in Terraform before the first workload arrives, with firewalls that deny by default and drift detection on a schedule.

  • Database migration

    SQL Server, PostgreSQL, MySQL and Oracle moved to managed services such as Azure SQL or Amazon RDS, rehearsed on a copy with a reconciliation report before the production run.

  • Applications in containers

    Applications packaged as containers and run on Azure Container Apps, AKS or Amazon ECS, with images built and scanned in the pipeline and deployed by digest.

  • Pipelines and secrets

    GitHub Actions or Azure DevOps pipelines that sign in with federated credentials instead of stored passwords, and every secret moved into Key Vault or Secrets Manager.

  • Cut-over and the first bill

    A cut-over plan with a rollback point, alerts live before traffic moves, and a review after the first month that right-sizes whatever was over-provisioned.

Hire cloud engineers

  • Dedicated cloud engineers

    Cloud engineers who join your team full time, work in your tools and process, and report to your lead. You interview them; we carry the Ukrainian contract, payroll, invoicing and leave.

  • Cloud migration projects

    A defined piece of cloud migration with a scope, a fixed plan and a named lead on our side who owns the result and reports progress in your channels.

  • Ongoing cloud migration

    Cloud migration as a continuing service: the same people every month, a backlog you prioritise, and hours you can see in our portal and on the invoice.

The dedicated team page explains how specialists join your team, and the outsourcing page covers project delivery, take-overs and how we charge.

Who works on your cloud migration

  • Cloud architects

    Assessment, landing zone and migration plan

  • Cloud and DevOps engineers

    Terraform, pipelines, networking and monitoring

  • Backend engineers

    The application changes the move needs, in .NET, Java, Python or PHP

  • Database engineers

    Schema, data migration and reconciliation

  • QA engineers

    Regression testing before and after cut-over

Azure, AWS or Google Cloud

Azure when your company already lives in Microsoft 365 and Entra ID or runs .NET and SQL Server, because identity, licensing and tooling carry over. AWS or Google Cloud when your team, your credits or a specific managed service point there. We recommend per workload, and for some of them staying where they are is the right answer.

Azure is where our own practice works every day: our estate is declared in Terraform and deployed from GitHub Actions with federated credentials and actions pinned by hash, with secrets only in Key Vault, deny-by-default firewalls and drift detection. A migration we run for you ends in the same state, in your own accounts.

Questions about cloud migration

Lift and shift, or rebuild for the cloud?

Rehosting is the fastest move and the right one for systems near the end of their life. Moving the database to a managed service and the application to containers or serverless costs more up front and usually less every month after. The assessment shows you that trade-off per workload, with the monthly cost of each option.

Will the migration cause downtime?

The cut-over is rehearsed on a copy first, scheduled outside your busy hours and planned with a rollback point. Where the database engine allows it, data is synchronised ahead of time, so the switch itself is short.

Can you move us from one cloud to another?

Yes. Moving between Azure, AWS and Google Cloud follows the same path: an assessment, a landing zone in Terraform, a rehearsed data migration and a planned cut-over, with each provider-specific service mapped to its equivalent or replaced.

How quickly can cloud engineers start?

When the right cloud engineer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.

How do we hire cloud engineers through BigTree108?

Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.

Who owns the work they produce?

You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.

Planning a move to the cloud?

Tell us what runs where today and why you want to move. You get an answer within one business day: an assessment plan, a first view of the target architecture or candidate profiles.
