Is your existing server still the right fit for your business?

IT Desk can review what your server currently does, identify which workloads could move to Microsoft 365 or Azure and recommend a practical on-premises, cloud or hybrid approach. We can also plan the migration, security, backup and ongoing management of the new environment.

Do small businesses still need physical servers?

Not necessarily.

A traditional small-business network often relied on a physical server located in the office. That server might have stored company files, managed user accounts, hosted email, controlled printers, run business applications and created local backups.

Many of those functions can now be delivered through cloud services.

For example:

• Microsoft 365 can provide business email and productivity applications.

• SharePoint can provide shared document storage.

• OneDrive can store an employee’s individual working files.

• Microsoft Teams can support communication and collaboration.

• Cloud-based applications can replace locally hosted accounting, CRM and operational software.

• Microsoft Entra ID and device-management services can help manage identities and business devices.

As a result, some businesses can retire their physical server rather than replacing it with another piece of hardware.

What is an on-premises server?

An on-premises server is physical or virtual server infrastructure located at a business premises or another location controlled by the organisation.

It may be used for:

• Shared company files

• User authentication

• Business applications

• Databases

• Email

• Printing

• Device management

• Remote access

• Backups

• Security or monitoring software

A server does not have to be a large machine in a dedicated data centre. It could be a relatively small device located in a communications cabinet or office.

Before removing one, the business needs to understand every service, application and process that depends on it.

Can Microsoft 365 replace a business server?

Microsoft 365 can replace several common server functions, but it does not automatically replace every server.

A business may be able to move:

This can reduce the need to purchase, power, cool, maintain and replace physical server hardware.

However, migration is not simply a matter of uploading every shared folder to OneDrive. Permissions, document ownership, file structures, security settings and user working practices must be planned properly.

When might a small business still need a server?

A server may still be appropriate when the business uses:

• Specialist software that must run on Windows Server

• A database requiring particular performance or configuration

• Manufacturing, design or engineering applications

• Equipment that depends on a local server

• Large files that need very fast local access

• Legacy software that does not support cloud hosting

• Systems that must continue operating during an internet outage

• Bespoke integrations built around the existing network

• Regulatory or contractual arrangements requiring a particular hosting model

In these situations, the organisation may retain its physical server, use a hybrid environment or move the workload to a cloud-hosted server.

The decision should be made application by application rather than treating the server as one indivisible system.

What is the difference between Microsoft 365 and a cloud server?

Microsoft 365 provides finished cloud services such as Exchange Online, SharePoint, OneDrive and Teams. Microsoft manages the underlying platform, while the customer manages areas such as users, permissions, devices and data.

A cloud server is a virtual machine running in a provider’s data centre. It behaves more like a conventional server and still requires an operating system, configuration, security, monitoring, patching and backup.

Moving a physical server into Microsoft Azure does not necessarily eliminate the server. It changes where that server runs.

This distinction matters because the two approaches solve different problems:

• Microsoft 365 can replace some traditional server functions with managed applications.

• A cloud server can host software that still requires a conventional server environment.

• A hybrid setup can combine cloud services with local or cloud-hosted servers.

Is a cloud server cheaper than a physical server?

It can be, but cloud hosting is not automatically cheaper.

A physical server normally requires a larger upfront purchase followed by ongoing costs for maintenance, electricity, cooling, backup, warranties and eventual replacement.

A cloud server usually has a lower initial hardware cost but creates continuing charges based on the resources and services consumed.

Cloud costs may include:

• Processing power

• Memory

• Storage

• Data transfer

• Backup

• Security

• Monitoring

• Software licensing

• Technical management

The comparison should cover the full expected life of the system rather than comparing a hardware quotation with one month of cloud hosting.

A poorly sized or unmanaged cloud environment can become unnecessarily expensive. Equally, an ageing physical server can create hidden costs through failures, slow performance and increasing maintenance.

Can a business work without a server if the internet goes down?

A cloud-dependent business will have reduced access to online services during an internet outage.

Some Microsoft 365 applications and synchronised files may remain available offline, but email delivery, live collaboration and cloud-hosted business systems normally require an internet connection.

This does not automatically mean a physical server is necessary. Businesses can reduce connectivity risks through:

• A secondary internet connection

• Automatic mobile or 4G/5G failover

• Business-grade connectivity

• Locally synchronised working files

• Documented downtime procedures

• Appropriate backup and disaster recovery plans

A physical server can also become unavailable because of power failure, hardware damage, ransomware or a local network problem. Neither model removes the need for resilience planning.

Is cloud storage the same as a backup?

No.

Cloud storage makes information available through an online service. A backup creates additional recovery copies so that data can be restored after deletion, corruption, ransomware or another incident.

Microsoft 365 includes retention, versioning and recovery capabilities, but the business should assess whether these meet its required recovery times and retention periods.

Moving files from a local server to SharePoint or OneDrive should therefore be accompanied by a suitable data-protection and backup plan.

Read our guide explaining how often a small business should back up its data once that Quick Answer page is published.

Should we replace our server or move to the cloud?

Start by identifying what the server currently does.

A server assessment should establish:

• Which applications are installed

• Who uses each application

• Where company data is stored

• Which devices and systems connect to it

• Whether any software is outdated

• How authentication and permissions work

• How the server is backed up

• What would happen if it failed

• Whether applications have supported cloud alternatives

• The cost of replacement, cloud migration and ongoing management

The result may be a fully cloud-based environment, a replacement physical server, a cloud-hosted virtual server or a combination of these.

The objective is not to move everything to the cloud simply because cloud services are available. It is to select the most appropriate platform for each business system.

Does a new small business need to buy a server?

Most new small businesses do not need to purchase a physical server immediately.

A new organisation can often begin with Microsoft 365, cloud-based accounting or CRM software, secure managed devices and cloud backup. This avoids building systems around hardware that may later need to be migrated.

A server might still be necessary if the business launches with specialist applications, performance requirements or equipment that depends on local infrastructure.

Technical requirements should be checked before software or hardware is purchased.
