If your business still runs on a physical server in the office, or on a hard drive someone has to remember to back up, you've probably weighed **cloud migration**. The real question is rarely whether it's worth it — it's what it costs and what actually changes the day after. Here's a look at the real benefits of moving your infrastructure to the cloud, what drives the price, and what cloud migration costs across the US, UK and EU, region by region.

## What is cloud migration?

Cloud migration means moving your servers, applications, data or backups off physical machines your company owns — in the office or in a data centre — onto a cloud provider's infrastructure, such as AWS, Microsoft Azure or Google Cloud. Instead of owning the machines, you **rent capacity** and access it over the internet, paying for what you actually use.

Not everything migrates the same way. There are two main approaches:

- **Lift and shift**: you move the application or system as it is, without rewriting it. It's faster and cheaper, but doesn't always make the most of what the cloud offers.
- **Refactoring**: you redesign the system to be cloud-native, taking advantage of its scalability and managed services. It costs more upfront, but usually pays off long-term if the system is going to run for years.

## Why small businesses are leaving the local server behind

A physical server ages like any other piece of hardware: it runs out of capacity, parts fail, and replacing it means buying new equipment upfront. If a drive fails, or there's a theft, a fire or a simple power surge, recovery depends entirely on the last backup being sound and stored somewhere other than that same room.

On top of that, scaling up on-premise isn't instant: you have to get a quote, wait for delivery, install it and configure it. In the cloud, the same change happens in minutes, from a control panel, with nobody heading to a server closet with a screwdriver.

## The real benefits of cloud migration

These are the benefits that actually show up in a business's day-to-day, beyond the providers' sales pitch.

### Cost savings: from buying hardware to paying for usage

The underlying difference is accounting: buying a server is a **capital investment** that depreciates over the years whether you use it fully or not. Paying for the cloud is a **variable cost** that rises and falls with actual usage. If a campaign or an order spike means you need more power one month, you pay for that month; once it drops, you stop paying for it. With your own server, that spare capacity was billed to you either way.

### Scalability: grow or shrink without construction work

Adding storage, memory or compute power is a matter of minutes, not weeks. This matters most if your business has seasonal spikes — sales periods, campaigns, peak season — since you can scale up right before and back down after, instead of paying year-round for capacity you only need for a few weeks.

### Security and automatic backups

Large providers encrypt data in transit and at rest, watch for suspicious access around the clock, and replicate information across multiple data centres. **Key idea:** that doesn't remove your responsibility. Cloud security is shared between the provider, who secures the infrastructure, and you, who has to configure permissions and passwords correctly. A folder left open to the public is still your mistake, no matter where it's hosted.

### Remote work and real-time collaboration

With files and applications in the cloud, anyone authorised can access them from wherever they are, with a connection and the right permissions. Several people can work on the same document or system at once, without emailing versions back and forth or overwriting each other's changes.

### Business continuity after failures or disasters

If a local server breaks, your business stops until it's repaired or replaced. In the cloud, data is usually replicated across multiple zones, so a failure in one data centre doesn't have to take your service down. Recovering a system from the cloud after an incident is generally a matter of hours, not days.

## What drives the price of a cloud migration

There's no single figure, because the cost depends on several decisions, not just on company size:

- **Lift and shift or refactoring.** Moving a system as-is is cheaper upfront than redesigning it to be cloud-native.
- **Data volume.** The more terabytes you need to move, the more transfer time, engineering hours, and — at large volumes — specialised data-migration tools it takes.
- **How many systems are connected to each other.** A standalone website moves on its own; an ERP linked to accounting, warehouse and website means coordinating several pieces at once.
- **Industry regulation.** Healthcare, finance or any sector handling sensitive data needs extra configuration and audits that don't apply to a business without those requirements.
- **Who does the work.** A freelancer, a specialised agency and an in-house team all have different cost structures, and it shows in the final budget.

## What cloud migration costs, region by region

Prices vary quite a bit from one market to another, so they're broken down by region and in each region's own currency, not converted:

| Project type | Spain / EU | UK & Ireland | US / Canada |
| --- | --- | --- | --- |
| Small business, simple setup (lift and shift) | €3,000-8,000 | £2,500-8,500 | $3,000-15,000 |
| More systems or higher data volume | €60,000-200,000+ | £15,000-50,000 | $50,000-250,000 |

On top of the migration project itself comes the **recurring cost** of running on the cloud (storage, compute, data transfer), which varies so much by volume that a fixed figure wouldn't mean much — it's calculated case by case with the chosen provider.

Worth knowing before you set a budget: according to [industry figures](https://aodatacloud.es/ebooks/migracion-cloud-costes-reales/), a significant share of migration projects end up costing well over the initial budget when they aren't planned properly. The cloud itself isn't expensive — a badly designed migration is.

If you're in Spain, part of the investment may qualify for the [Kit Digital](https://espanadigital.gob.es/lineas-de-actuacion/programa-kit-digital) grant, under the process-management or cybersecurity categories, depending on the current call and business size. If you're elsewhere, it's worth checking whether your government runs an equivalent SME digitalisation scheme — several do.

## What happens when a migration is done badly

Almost every cloud migration problem starts in the same place: doing it without a plan, in a rush, or all at once.

- **The budget blows up.** Without an upfront review of what's actually running, forgotten systems surface halfway through the project, and every surprise adds hours nobody budgeted for.
- **The service goes down during the switch.** Migrating everything at once, without a period where the old and new systems run side by side, leaves the business without systems while the first bugs get sorted out.
- **Data gets lost.** If the backup isn't verified before the old system is switched off, a failure during migration can leave gaps that never get recovered.
- **Two systems stay live forever.** A half-finished migration, where part of the business stays on-premise «just in case», ends up costing double: both infrastructures have to be maintained at once.
- **Doors get left open.** Cloud storage misconfigured as public is one of the most common security failures out there, and it isn't the provider's fault — it's a configuration mistake.

## What a solid migration process includes

1. **Audit the current state**: which systems exist, which are actually used, and which can be retired before anything gets moved.
2. **Choose the migration type** for each system: lift and shift where it's enough, refactoring where it pays off.
3. **Plan it in phases**, starting with the least critical systems, not everything at once.
4. **Take a full, verified backup** before touching the original system.
5. **Run both infrastructures side by side** for a while, until everything is confirmed to work as well or better.
6. **Verify and decommission** the old system, only once the new one has proven stable.

## By business stage

There's no single right answer, and anyone who gives you one without asking where your business actually stands isn't advising you — they're selling to you.

- **Just starting out, or running a simple setup?** Moving email, files and little else to already-configured services is usually enough, without a complex migration project behind it. It's the fast, cheap way to stop depending on a single hard drive.
- **Already generating revenue with your own systems** (ERP, CRM, custom applications)? Migration needs phased planning and, almost always, help from someone who's done it before. Skipping the upfront audit here almost always ends up costing more.

## How we approach it at Cruslar

Before moving anything, we start with the same thing we recommend in this article: auditing what's actually running and what's actually used. We don't propose a full migration to someone who just needs to stop depending on a shared hard drive, nor a surface-level change to someone with critical processes running on-premise. The plan comes from what we find in your infrastructure, not from a fixed package sold the same way to everyone. It's the same thinking we apply when recommending which [tasks to automate first](https://cruslar.com/blog/tasks-to-automate-in-your-business) in a business, and it carries through every [IT solutions](https://cruslar.com/services/soluciones-it) project we deliver.

## Frequently asked questions

### Is it safe to migrate to the cloud?

It can be safer than a local server, as long as it's configured correctly. Large providers secure their infrastructure, but access and permission configuration is still the migrating company's responsibility.

### How long does a cloud migration take?

It depends on volume and complexity. A simple email-and-files migration can be done in days; a system with several integrations usually takes weeks, spread across phases.

### What happens to my data during the migration?

It needs to stay accessible and intact throughout. That's why a verified backup before starting isn't optional — it's the safety net if something fails halfway through.

### Can I migrate only part of my business to the cloud?

Yes, and it's usually the recommended approach at first. Starting with the least critical pieces — email, files, backups — leaves room to learn before moving the systems your daily revenue depends on.

### Is the cloud cheaper than running your own servers?

For most small businesses, yes, over the medium term: you cut the upfront hardware investment and its upkeep. But recurring cloud spend needs watching too — a poorly sized setup can get expensive as well.
