Migrate to the cloud (Azure/AWS) without stopping operations
We move your applications and data to Azure or AWS with a clear 6R strategy — not a blind lift&shift that just relocates the problem to the cloud. We start with a readiness assessment, build the landing zone with Terraform, and migrate in waves, validating each workload in parallel before cutover. The infrastructure and the code are 100% yours.
Cloud migration means moving your applications, databases and infrastructure from an on-premise datacenter (or another provider) to Azure or AWS, choosing for each workload the right strategy from the 6R model: rehost (lift&shift), replatform (minimal changes), refactor (re-architect), repurchase (SaaS), retain (keep it) or retire (shut it down).
Not everything migrates the same way: a critical app with a transactional database is not treated like a file server. We do it in waves, with parallel migration and a controlled cutover, so your operation never stops.

When you need it
What it includes
Readiness assessment
Inventory of applications, dependencies and data. We evaluate each workload with Azure Migrate (or its AWS equivalent), measure real consumption and define the 6R strategy per application. We come out with a wave map, risks and a cloud cost estimate — before committing budget.
6R migration plan
For each workload we decide rehost, replatform, refactor, repurchase, retain or retire — and we explain why. A wave plan with dependency order, migration windows, success criteria and a rollback plan per workload.
Landing zone (IaC)
We build the cloud foundation as code with Terraform: networks, subscriptions/accounts, identities, security policies, tagging and cost governance. Reproducible, versioned and 100% yours — no hand-made configurations nobody can reproduce.
Data and application migration
We move databases (PostgreSQL, SQL Server) and applications in waves. When it applies, we replicate in parallel and validate consistency before the cut; we containerize with Docker the workloads that warrant it. Continuous sync until cutover to minimize downtime.
Validation and cutover
Smoke, performance and integration tests in the cloud before redirecting traffic. Cutover in an agreed window with the option to fall back to the source if anything fails. Each wave is validated in production before moving to the next.
Replatforming to managed services
When it pays off, we don't just move the VM: we take databases to managed services (Azure Database / Amazon RDS), queues and cache to native services, to cut manual operations without a full re-architecture.
Identity and hybrid connectivity
We integrate identity (Entra ID / IAM) and network connectivity between your on-premise and the cloud (VPN or dedicated link) so the wave migration coexists with what we haven't moved yet, without cutting access or integrations.
Post-migration optimization
After the cut: rightsizing, reservations/savings plans, budget alerts and cleanup of orphan resources. A poorly sized cloud costs more — we tune it so you pay for what you use.
How we work
01 · Assessment & readiness
We inventory applications, data and dependencies with Azure Migrate. We assign the 6R strategy per workload, group them into waves and estimate cloud cost. We come out with a phased migration plan and a business case.
02 · Landing zone
We build the Azure or AWS foundation as code (Terraform): networks, identities, security, cost governance and CI/CD. The foundation is reproducible and versioned before moving a single workload.
03 · Wave migration
We migrate workload by workload following the 6R plan. For critical ones we replicate in parallel and validate consistency before cutover. Each wave is tested in production before moving to the next.
04 · Optimization & handoff
Rightsizing, cost control, monitoring and alerts. Documentation, runbooks and knowledge transfer. Infrastructure, IaC and code 100% yours.
05 · Stabilization & closeout
Post-cutover support (hypercare): we watch performance, cost and errors against real traffic, decommission the source environment once you confirm everything runs well, and formalize the closeout. Deliverable: a closeout report and a stabilized operation in your cloud.

The tools and platforms we build it with — chosen for your problem, not for hype.
Frequently asked questions
Will there be downtime during the migration?
We minimize it as much as possible and, for many workloads, we avoid it. We migrate in waves with parallel replication: the app keeps running at the source while we sync data to the cloud, and we only do a short cutover in an agreed window once the new workload is validated. If something fails during the cut, we fall back to the source. Actual downtime depends on each application; we estimate it workload by workload in the assessment.
Lift&shift (rehost) or refactor? Which one fits me?
It depends on each workload, which is why we use the 6R model instead of migrating everything the same way. Rehost (lift&shift) is fast and cheap but does not leverage managed services or lower costs on its own. Refactor (re-architecting to containers, serverless or managed databases) costs more upfront but reduces operations and cost over time. In practice we recommend starting with rehost/replatform to get out of the datacenter and refactoring later the workloads that most justify it. We tell you which one applies to each app, with no agenda.
Azure or AWS? Which one should I choose?
Both are solid; the decision depends on your context, not on a preference of ours. What matters is your current stack (if you already use Microsoft 365, Active Directory or SQL Server, Azure usually integrates better), your licensing agreements, your team's skills and the specific services you need. Our cloud track record has a verifiable name: Soriana — legacy store systems, TMS, OMS and a payment gateway running on Azure across 800+ stores. If you have no preference, we evaluate it in the assessment and give you a reasoned recommendation.
How much does it cost and how long does a cloud migration take?
The migration project is quoted with a fixed budget after the assessment — it depends on the number of workloads, their complexity and the 6R strategy of each. The recurring cloud cost we estimate in the assessment using real consumption, not assumptions. Migrating in waves lets you spread the investment and start leaving the datacenter from the first weeks instead of waiting for a big-bang. The infrastructure, the landing zone and the IaC are 100% yours.
Do the infrastructure and cloud control stay mine?
Yes, without exception. The Azure or AWS subscription/account is yours and in your name, the landing zone is defined as code (Terraform) in your repository, and we hand over documentation, runbooks and knowledge transfer. We do not lock you into a console only we understand: everything is reproducible and operable by your team.
