Cloud migration services
Cloud migration moves applications, data and infrastructure from on-premises servers or another host to a cloud platform. Stackvala assesses each workload, plans the move in stages and tests the cutover before production is touched.
Cloud migration services: moving without the drama
Cloud migration is the process of moving applications, data and infrastructure from on-premises servers or a legacy hosting provider into a cloud platform such as AWS, Microsoft Azure or Google Cloud. Done well, it improves reliability, lets you scale on demand, shortens delivery cycles and replaces large hardware purchases with a usage-based cost. Done carelessly, it creates surprise bills, downtime and security gaps.
Stackvala helps US businesses plan and execute cloud migrations in stages that protect operations. We begin by understanding what you run and why, choose the right migration path for each workload and test the move before real users are affected. The goal is not simply to relocate servers; it is to land on an environment that is cheaper to run, easier to secure and ready for what comes next.
- Data-centre or colocation exit projects
- Moving a single critical application to the cloud
- Consolidating several hosting providers into one platform
- Preparing a system for growth, compliance or a customer requirement
- Replacing end-of-life servers or operating systems
- Disaster recovery and backup modernization
The migration strategies, and when each fits
Not every workload deserves the same treatment. A good plan assigns each application the lightest approach that achieves its goal.
| Strategy | What happens | Best for | Trade-off |
|---|---|---|---|
| Rehost (lift and shift) | Move servers largely as they are | Fast exit from hardware, tight deadlines | Limited cloud benefits at first |
| Replatform | Move with targeted upgrades, such as managed databases | Reducing operations effort quickly | Moderate change and testing |
| Refactor | Redesign for cloud-native services | Applications needing scale and agility | Highest effort, highest long-term gain |
| Replace | Switch to a SaaS product | Commodity functions such as email or HR | Data migration and process change |
| Retire | Switch off what is unused | Redundant or obsolete systems | Needs confirmation with owners |
If an application is a candidate for deeper change, our legacy modernization practice can combine migration with code improvements.
Our cloud migration process
A predictable sequence keeps risk low and stakeholders informed.
Assess
Inventory servers, applications, dependencies, data volumes and current costs.
Plan
Choose provider, landing zone, strategy per workload and a migration sequence.
Prepare
Build secure networking, identity, monitoring and backup foundations as code.
Migrate
Move workloads in waves with rehearsals, data sync and rollback plans.
Optimize
Right-size resources, tune performance and set cost alerts and budgets.
Key points
Security and compliance in the cloud
Cloud providers secure the infrastructure; you secure what you put on it. Clear ownership of that shared responsibility is the first step.
Identity and access
Least-privilege roles, multi-factor authentication and no shared root credentials.
Network design
Private subnets, firewalls and controlled entry points.
Encryption
Data protected in transit and at rest, with managed key storage.
Logging and monitoring
Centralized audit trails and alerts for suspicious activity.
Backups and recovery
Tested restores and defined recovery targets.
Regulated workloads
Configurations that support HIPAA, PCI DSS or SOC 2 programs where they apply.
In detail
Controlling cloud cost
The cloud’s flexibility is also its financial risk. Cost discipline starts before the first server moves.
These practices continue after migration through our cloud and DevOps services.
Right-sizing
Match instance sizes to real usage rather than old hardware specifications.
Reserved and committed capacity
Discounts for steady workloads.
Automatic scheduling
Shut down non-production environments out of hours.
Tagging and budgets
Assign costs to teams and set alerts before overruns.
Storage lifecycle policies
Move cold data to cheaper tiers.
Key points
Downtime, testing and rollback
Business leaders mostly want to know one thing: what happens to service during the move. We plan for that explicitly.
Pilot migrations
Start with a low-risk workload to prove the approach.
Continuous data replication
Keep old and new data in sync until cut-over.
Performance and functional testing
Validate in the new environment before switching users.
Scheduled cut-over windows
Timed around your business calendar.
Rollback options
The old environment stays available until the new one is proven.
In detail
Cost and timeline
Migration timelines range from weeks for a single application to many months for a full data-centre exit.
We provide a written assessment and plan before any migration work begins. See pricing models to choose a contract that fits.
Number of workloads and dependencies
More systems mean more planning and testing.
Data volume
Large datasets take longer to transfer and verify.
Required downtime window
Smaller windows need more engineering.
Compliance
Regulated environments need additional configuration and evidence.
Post-migration support
Monitoring and optimization can be scoped separately.

Contact StackvalaWhat is cloud migration?
It is moving applications, data and infrastructure from on-premises servers or another hosting environment to a cloud platform such as AWS, Azure or Google Cloud.
How long does cloud migration take?
Single applications can move in weeks, while larger estates take several months. A discovery assessment produces a realistic wave plan.
Will there be downtime during migration?
We aim for minimal downtime using data replication, rehearsals and scheduled cut-overs, with a rollback plan if something is wrong.
Which cloud provider should we choose?
AWS, Azure and Google Cloud are all strong options. We compare them against your existing tools, skills, compliance needs and cost, then recommend one.
Can migration reduce our infrastructure costs?
Often, but not automatically. Savings come from right-sizing, committed-use discounts, automation and retiring unused systems, which we build into the plan.
Is the cloud secure enough for sensitive data?
Yes, when configured correctly. We apply least-privilege access, encryption, logging and backups, and support regulated workloads.
Do you offer support after the migration?
Yes. We provide monitoring, cost optimization and ongoing DevOps support on a plan you can adjust.
