"Should we move to the cloud?" is the wrong question in 2026, because you almost certainly already have. If you use Microsoft 365, you're in the cloud. The real question is how far to go, and which of your remaining on-premise systems should follow.
Here's an honest framework, including the cases where staying put is the right answer.
What "moving to the cloud" actually means
Three distinct things get bundled under the same phrase:
- SaaS, using someone else's application. Microsoft 365, Xero, your CRM.
- IaaS, renting virtual servers and running your own systems on them, typically in Azure.
- PaaS, building on a managed platform without touching servers at all.
Most SME decisions are about the first two. Confusing them makes the cost comparison meaningless.
Good reasons to move
Your server is coming up for renewal. The strongest trigger. If you're facing a five-figure hardware refresh plus Windows Server licensing, that's the moment to compare a cloud migration properly.
Your team works from multiple locations. Cloud removes the VPN dependency and the "I can't get to the file server from home" ticket.
You need resilience you can't build yourself. A single server in a cupboard has one power supply, one air conditioning unit, and one flood risk. Azure has considerably more.
You want predictable monthly costs instead of capital spikes. Useful for cash flow, though not automatically cheaper overall.
You're growing or shrinking unpredictably. Scaling a physical server means buying one. Scaling a cloud one means changing a setting.
Genuinely good reasons to stay put
Being honest about this matters more than the sales pitch.
You have a large volume of data with constant local access. CAD files, video, large design libraries. Bandwidth becomes the bottleneck and egress charges add up.
Your line-of-business application isn't cloud-friendly. Plenty of specialist software still assumes a local server. Forcing it into the cloud produces a slower, more expensive version of what you had.
You have a new server with years of life left. Migrating for the sake of it wastes the asset.
Your connectivity isn't up to it. Cloud makes your internet connection a single point of failure. If you're on a contended broadband line, sort connectivity first, a leased line usually needs to come before the migration, not after.
Comparing costs properly
The comparison most people run is wrong because it puts hardware against subscription and stops there. Include:
- Hardware, plus the replacement in five years
- Windows Server and CAL licensing
- The power, cooling and space the server uses
- Your backup and disaster recovery capability in each model
- Downtime risk and what an outage actually costs you per day
- Internet connectivity upgrades
- Migration project cost, one-off
- Ongoing management in each model
Cloud often lands slightly higher on paper and better on total risk. That trade-off is a business decision, not a technical one.
The hybrid answer
For most of the SMEs we work with, the sensible outcome isn't all-or-nothing. It's:
- Email, files and collaboration in Microsoft 365 with SharePoint and OneDrive
- Line-of-business applications wherever they run best, cloud if supported, local if not
- Backups always offsite and independent
- A single identity across the lot, with MFA and conditional access
This gets you the resilience and flexibility benefits without breaking the application that runs your business. Our guide to integrating cloud services with legacy IT goes deeper on the mechanics.
Questions to answer before you commit
- What is the actual business problem you're solving? "Everyone's doing it" isn't one.
- Does every critical application support the target platform, confirmed with the vendor, in writing?
- What's your internet connection, and what happens to the business if it drops for a day?
- Who is responsible for backups after the move? (In IaaS, still you.)
- Where will data be stored, and does that satisfy your compliance obligations?
- What does the exit look like if the platform stops suiting you?
Doing it properly
A migration that's planned around your applications and connectivity is straightforward. One that's planned around a subscription price usually isn't.
