Cloud migration services planned around the monthly bill
We move applications and data to AWS, Azure or Google Cloud, choosing per workload between a quick rehost and a deeper rebuild.

At a glance
Cloud migration is moving your servers, applications and databases from on-premises or hosted infrastructure to AWS, Microsoft Azure or Google Cloud. It suits mid-sized companies facing a hosting renewal, a VMware price jump or aging hardware. Tag4 Technology Solutions decides per workload whether to rehost or rebuild, sets up a Terraform landing zone and models the monthly bill before anything moves.

Companies usually come to us for cloud migration services when something forces the issue. A hosting contract is ending, a server room lease is up, or a VMware renewal quote arrived far higher than the last one after Broadcom's licensing changes. Sometimes it's simpler: the one person who understood the on-premises servers is retiring. We work with mid-sized US companies moving anywhere from a handful of servers to a few hundred workloads onto AWS, Microsoft Azure or Google Cloud.
The expensive mistake is treating the cloud like a rented data center. Teams lift every virtual machine as-is, size them to match old hardware, leave them running 24/7, and then watch the bill come in higher than the colocation invoice it replaced. The opposite mistake hurts too. Some teams decide to re-architect everything into microservices at once, and eighteen months later half the apps still haven't moved. Poor network planning, forgotten dependencies between systems and backups nobody tested round out the list.
We assess each workload and give it a plain recommendation. Stable apps with no roadmap often get rehosted as-is, then rightsized once we see real usage. Databases usually move to managed services like Azure SQL or Amazon RDS, which removes patching work. Apps you're actively developing may justify replatforming to containers or serverless. Everything lands in a landing zone built with Terraform, with identity, networking, tagging and budgets set up before the first workload arrives. Cutovers are rehearsed, and rollback plans are written down.
Migrating a small environment of 10–30 servers typically takes 6–12 weeks. Larger estates with complex dependencies run 4–9 months in waves. After the move, rightsizing, savings plans or reservations and scheduled shutdowns for non-production often bring costs down noticeably, and we keep watching the bill for the first few months.
What we do
Cloud Solutions services
Migration assessment
Discovery of servers, apps and dependencies, with a per-workload recommendation (rehost, replatform, refactor, replace or retire) and a cost estimate for each.
Landing zone setup
Accounts or subscriptions, networking, identity, logging, tagging and policy guardrails written as Terraform, so the foundation is repeatable and reviewable.
Lift-and-shift migrations
Rehosting virtual machines with AWS Application Migration Service or Azure Migrate, scheduled in waves with rehearsed cutovers and minimal downtime.
Database migration
Moving SQL Server, Oracle, PostgreSQL or MySQL to managed cloud databases, with replication running until cutover so the switch takes minutes.
Application re-architecture
Containerizing apps, breaking out services where it pays off, and adopting serverless for spiky or event-driven workloads.
Cloud cost optimization
Rightsizing, savings plans, reserved capacity, storage tiering and shutting down idle resources, with monthly reviews against a budget you set.
Hybrid and multi-cloud
Secure connectivity between your offices, remaining on-premises systems and one or more clouds, for companies that cannot move everything at once.
How we work
What you can expect from us
One decision per workload
We avoid blanket strategies. Each app gets the treatment its value and lifespan justify, which keeps both timeline and budget honest.
Costs modeled before moving
You see an estimated monthly bill for the target environment before migration starts, and we compare actuals against it afterward.
Rehearsed cutovers
Every production move is practiced in a test run first, with a written rollback plan and a clear go or no-go decision point.
Cloud-neutral advice
We work across AWS, Azure and Google Cloud. If you're a Microsoft shop, Azure is often the natural fit, but we'll say so only when it's true for you.

Process
From first call to production
Discovery
A few working sessions to pin down goals, users, constraints and what "done" means. You get a written scope and estimate.
Design
Architecture, data model and clickable UI before heavy coding starts, so surprises show up early and cheaply.
Build
Two-week sprints with a demo at the end of each one. You see working software, not status reports.
Launch
Automated tests, staged rollout, monitoring and a rollback plan. Go-live should be boring.
Support
Bug fixes, updates and new features on a monthly plan, or a clean handover to your team.
FAQ
Cloud Solutions: common questions
Will moving to the cloud save us money?
It can, but not automatically. A straight copy of oversized, always-on servers often costs more than on-premises. Savings come from rightsizing, managed services that remove maintenance work, and shutting down resources outside business hours, and we model those before you commit.
Should we choose AWS, Azure or Google Cloud?
If you run Microsoft 365, Dynamics 365 and Windows servers, Azure usually integrates most easily and may reduce licensing costs through Azure Hybrid Benefit. AWS has the broadest service catalog and a deep hiring pool. Google Cloud is strong for data and analytics workloads. Existing skills and contracts often matter more than feature lists.
How much downtime should we expect during migration?
For most workloads, a cutover window of a few minutes to a couple of hours, usually scheduled overnight or on a weekend. Databases are replicated ahead of time so only the final sync happens during the window. Some legacy systems need longer, and we identify those during assessment.
What is the difference between lift-and-shift and re-architecting?
Lift-and-shift moves an application to cloud VMs with little or no change, which is fast and low-risk. Re-architecting rebuilds parts of the app to use managed or cloud-native services, which takes longer but lowers running costs and maintenance. Most migrations use a mix, decided per application.
Can you manage our cloud environment after the migration?
Yes. We offer ongoing monitoring, patching, cost reviews and infrastructure changes through our DevOps and managed IT services. Some clients prefer to take it in-house, and we hand over the Terraform code and runbooks to make that straightforward.
