Do you still need a server? The 10 to 30 user question

The server in the closet is 7 years old. The warranty expired 2 years ago. It hosts the shared drives, maybe QuickBooks, maybe an old line-of-business application nobody wants to touch. And now an IT provider has handed over a refresh quote, typically $8,000 to $15,000 for the hardware alone once you add licensing, backup and labor.

For a company with 10 to 30 users, that quote deserves a hard question before anyone signs it: does this business still need a server at all?

The honest answer is usually “less than you think, but maybe not zero.” Here is how we walk through the decision at Atticus Rowan.

What the server is actually doing

Before comparing costs, inventory the workloads. In a typical 10 to 30 user office the aging server is doing some mix of:

• File shares. The S: drive everyone maps at login
• Print serving. Often vestigial, most modern printers do not need it
• Active Directory. User accounts and passwords for the office PCs
• QuickBooks or another accounting package in multi-user mode
• 1 or 2 line-of-business applications. Estimating software, practice management, an old database the industry vendor sold you in 2016
• Scanned-document dumping ground from the copier

Each of these has a different cloud story. Treating them as one lump (“we need a server for our stuff”) is how businesses end up buying hardware they no longer need.

What moves to the cloud cleanly

File shares are the easy win. If your company already pays for Microsoft 365, SharePoint and OneDrive are included in the licensing you own today. Moving 200 GB of office documents into SharePoint document libraries eliminates the single biggest reason the server exists. Files become available from anywhere, versioning is automatic and the data lands inside the same security boundary as your email.

Print serving can almost always die with the server. Modern printers accept direct connections or Universal Print.

User identity can move too. Microsoft Entra ID (what Azure Active Directory became) can be the only directory a small business needs. New PCs join Entra directly, sign-in uses the same account as email and there is no domain controller humming in a closet. For a 10 to 30 user company created in the last decade this is the default we recommend. For an older company with 15 years of Group Policy accumulation, the migration takes planning, but it is a one-time project, not a reason to buy servers forever.

What genuinely still needs on-prem hardware

Some workloads resist the move, and pretending otherwise causes expensive regret:

• Legacy line-of-business applications. If the vendor’s answer to “do you have a cloud version” is a hosted remote desktop at $150 per user per month, running it on a small local server may still win on cost
• Large-file work. CAD, video, high-resolution imaging. SharePoint has file size and sync limits, and a drafting team pulling 500 MB assemblies all day will feel every one of them
• Shop-floor and equipment-adjacent systems. Machine monitoring, label printing, scale integrations. Anything wired to physical operations usually wants local infrastructure, a topic we cover in network segmentation for small business
• Sites with unreliable internet. Cloud-first assumes the connection is up. A single-circuit rural office should think hard before making every file remote

If 1 of these applies, the answer is often a much smaller server than the quote proposes. A single application host is a far cheaper machine than a do-everything box sized for file storage it no longer carries.

The real cost comparison

The refresh path costs more than the hardware line item suggests. A realistic 5-year view for a 20-user office:

• Server refresh: $8,000 to $15,000 up front, plus Windows Server and client access licensing, plus backup licensing and storage, plus the support labor a physical box consumes. Spread over 5 years, commonly $400 to $600 per month all-in
• Cloud path: often $0 in new licensing if Microsoft 365 Business Standard or Premium is already in place, plus a one-time migration project (typically $3,000 to $8,000 at this size), plus a proper backup of the cloud data itself

The cloud path is not free. Migration is real work, and Microsoft 365 data still needs independent backup. But it converts a recurring hardware cycle into a one-time project, and it removes the single point of failure sitting in a closet with a consumer surge strip.

The migration realities nobody mentions

We are direct with clients about the friction:

• File path habits die hard. Mapped-drive muscle memory, shortcuts and linked spreadsheets all break when files move. Budget real time for cleanup and communication, not just the data copy
• OneDrive sync has limits. Syncing an entire 300 GB SharePoint site to every laptop ends badly. Teach “access online, sync selectively”
• Permissions need rethinking. A 2009-era folder tree with 40 permission exceptions should not be recreated verbatim. Flatten it into a handful of libraries with clear ownership
• The old server does not leave immediately. Plan a 30 to 60 day overlap where it runs read-only while stragglers surface

A typical 10 to 30 user migration runs 4 to 8 weeks from kickoff to server retirement, most of it waiting on data transfer and user cutover windows rather than heroics.

How to decide

The decision tree we use:

• No legacy apps, no large-file work, decent internet: retire the server. Go cloud-first and do not look back
• 1 stubborn application: shrink the server. Move files and identity to the cloud, keep a small host for the app, revisit when the vendor finally ships something modern
• Heavy CAD or shop-floor systems: keep local infrastructure, but still move email-adjacent files and identity to the cloud so the server does 1 job instead of 6

Whichever branch you land on, make the choice deliberately. The worst outcome is paying $12,000 to recreate 2016 because nobody asked the question.
