Server for a Small Business: Do You Need One, Which One and What Drives the Cost

In short:

• A server is a computer that runs non-stop and provides shared resources to everyone: files, applications, databases, users and permissions.
• If you only work with email and documents, Microsoft 365 is often enough and you do not need a server.
• A server makes sense with local accounting or warehouse software, many shared files, strict control over permissions, or NIS2 and GDPR requirements.
• The cost depends on the hardware, licences, backup and support - not only on the machine itself.

What is a server, in plain words

A server is a computer built to run day and night and serve the other computers on the network. Employees do not work on it directly; they use what it provides:

• shared files and folders, with permissions for who can see and change what;
• business applications and databases - accounting, warehouse, ERP, CRM;
• users and passwords in one place (a domain), instead of separately on every computer;
• printers, backups and internal systems.

The difference from an ordinary computer is reliability: two or more disks that mirror each other (RAID), redundant power, remote management and parts built for continuous operation.

Do you need a server at all

Before choosing a model, be clear about what the server has to do. Often the best solution is not to have a server in the office.

If your software runs in the vendor's cloud and your files are in Microsoft 365, a server in the office often just adds cost and risk.

NAS, an office server or a server in the cloud

One physical server can host several virtual ones - for example one for files and users and another for the accounting software. This saves hardware and makes recovery faster. See server virtualization for business: when is it worth it, and for choosing between the office and the cloud, on-premise vs cloud infrastructure.

Which server you need

The size is not chosen by eye. This is what we look at:

• The number of users and the applications that will run on the server, and how heavy their databases are.
• The volume of data now and in 3-5 years - files grow faster than it seems.
• Disks and RAID - SSDs for databases, mirrored disks so work does not stop when one fails.
• Redundant power - two power supplies and a UPS that shuts the server down properly in a power cut.
• Location - a rack or a room with a normal temperature, not under a desk next to the radiator.
• Warranty and parts - how quickly a replacement disk or power supply arrives if something fails.

What drives the cost

When you search for "server price", you only see the price of the machine. The real cost for the business has several parts:

A virtual server in the cloud has no large upfront purchase, but a monthly fee. With a short horizon or work from several places, this is often the better deal. With heavy local applications and a lot of data, your own server usually pays for itself.

The mistakes that cost the most

• An ordinary computer instead of a server. It works until the disk fails. Then there is no second disk, no guaranteed parts and often no copy.
• RAID without monitoring. One failed disk does not stop the server, so nobody notices until the second one fails too.
• The backup is on the same server. With a failure, theft or ransomware you lose both the data and the copy. See how to back up company data without risk.
• No UPS. A sudden power cut can corrupt the accounting software's database.
• Forgotten licences. Windows Server also needs access licences for users. In a Microsoft audit, missing licences cost more than buying them on time.
• Everything is in one person's head. Without documentation and with passwords not in the company's name, every change of person or provider is a risk.
• A server nobody updates. An outdated server reachable from the internet is one of the most common entry points for attacks.

How we do it

First we look at how the business works: which applications you use, how much data there is and where people work from. Sometimes the recommendation is to have no server in the office and to move to Microsoft 365 instead. When a server makes sense, we propose a new or used server matched to the load, or a virtual server in our own infrastructure in Bulgaria for our subscription support clients. We support Windows and Linux servers and virtualization with Proxmox.

Then we take over the support: 24/7 monitoring with Zabbix (including the disks and RAID arrays), planned updates, backups with restore testing and documentation of the environment. See server support for business.

Frequently asked questions

How much does a server for a small business cost?

It depends on what it will do: the number of users, the applications, the volume of data, the licences and the backup. That is why we first review your needs and then propose a specific solution and price - sometimes that is a smaller server, and sometimes the cloud instead of a server.

Can an ordinary computer work as a server?

For a test, or for 2-3 people for a short time - yes. For the company's data it is not a good idea: there are no mirrored disks, no redundant power and no fast parts when something fails.

NAS or server?

A NAS is enough for shared files. For business applications with a database, centrally managed users and stricter control over permissions, you need a server.

A server in the office or in the cloud?

In the office - with heavy local applications, a lot of data and a slow internet connection. In the cloud - when people work from different places and you do not want hardware in the office. Often the best option is a combination.

How many years does a server last?

Usually 5-7 years with normal use and support. After the warranty ends, the risk of failure and the repair time grow, so the replacement should be planned in advance.

Do we need Windows Server?

If your applications require Windows, or you want a domain with central user management - yes. For files, backups and some services, Linux is perfectly suitable and needs no licences.

A real-world example: how we expanded a server's RAID array from 8 to 24 TB without a new server.
