Should your IT infrastructure be operated in the cloud or continue to run in your own data centre? Many companies are asking themselves this question today. Cloud solutions and on-premise solutions offer different advantages, ranging from high flexibility to maximum control over data and systems.
But which solution better meets the requirements of your business? In this blog post, we compare cloud and on-premise solutions and highlight their key differences.
A cloud solution provides IT resources such as data, computing power, and software via the cloud, rather than running them locally on a computer or on the company’s own servers. The required infrastructure is provided and managed by a cloud provider.
This means companies do not need to purchase or maintain their own hardware, reducing high upfront costs and time-consuming maintenance. Instead, users access the external servers over the internet and can use applications and data from different devices and locations. The cloud is based on interconnected data centres, where large amounts of IT resources are pooled. This allows multiple users to access the same services simultaneously.
Cloud solutions are not limited to online storage but also include various service models, such as Software as a Service (SaaS), Infrastructure as a Service (IaaS), and Platform as a Service (PaaS). Infrastructure management, maintenance, updates, and security are usually handled by the cloud provider.
Advantages of a Cloud Solution
Risks of Using a Cloud Solution
Access to cloud services is via the internet. Users can connect to applications or storage in several ways, e.g., via a web browser, apps, software clients, technical interfaces and protocols, or through a local network or VPN.
Data and applications are stored and processed in external data centres, allowing companies to use IT resources flexibly and quickly scale them up or down as needed.
An on-premise solution refers to an operating model in which software, data, and IT systems are run on a company’s own hardware or within its in-house data centre. Applications are installed, managed, and used directly on the company’s servers, giving organisations full control over their IT infrastructure, data, and security policies.
However, this model also means that installation, maintenance, updates, and security measures must be handled internally. Companies typically require their own IT resources, hardware, and skilled personnel. On-premise solutions are often used by organisations with particularly high demands for data protection, security, or customised system configurations.
Advantages of an On-Premise Solution
Disadvantages of an On-Premise Solution
In an on-premise solution, applications and data are hosted directly on local servers or within the company’s own data centre. Access is typically via the internal company network (LAN), VPN connections for remote employees, or company-specific applications and software clients.
| Criterion | Cloud Solution | On-Premise Solution |
|---|---|---|
| Infrastructure | Provided and managed by the cloud provider | Managed within the company's own premises or data centre |
| Capital expenditure | Provided and managed by the cloud provider | Operated within the company's own premises or data centre |
| Maintenance & Updates | Handled by the cloud provider | Must be performed by the company's own IT team |
| Scalability | Highly flexible, resources can be quickly scaled up or down | Limited scalability when requirements increase |
| Access | Access via Internet, browser, apps or APIs | Primarily accessed via internal network or VPN |
| Data storage | Access via Internet, browser, apps or APIs | Typically accessed via internal network or VPN |
| Control over Data | Limited, as the infrastructure is managed by the provider | Very high, as full control remains within the company |
| Security | High security standards by the cloud provider, but data is stored externally | Security measures are fully managed by the company |
| Flexibility | Very high, especially for remote work and distributed teams | Less flexible, as it is tied to local infrastructure |
| Internet Dependence | Internet connection required | Can operate without a permanent internet connection |
| Operating Costs | Ongoing costs, but no expenses for own servers | Ongoing costs for maintenance, servers, and IT staff |
Whether a cloud solution or an on-premise solution is more suitable depends on the specific requirements of a business. Factors such as budget, security needs, flexibility, and available IT resources play a key role.
A cloud solution is particularly suitable for businesses that need a flexible, scalable, and low-maintenance IT infrastructure. As no own hardware is required, resources can be quickly adjusted, and applications can be accessed from multiple locations. The cloud is especially efficient and cost-effective for start-ups, small and medium-sized enterprises, or teams with remote working arrangements.
On the other hand, an on-premise solution is ideal for businesses with high demands for data protection, security, and control over their IT systems. Since all data is stored within the company’s own network, organisations retain full control over their infrastructure. This approach is often preferred by organisations handling sensitive data or with specific compliance requirements, such as in finance, healthcare, or public administration. However, businesses must also invest in hardware, maintenance, and IT personnel.
Whether cloud or on-premise, both IT operating models have clear strengths and are suited to different requirements. Cloud solutions impress with flexibility, scalability, and low maintenance, while on-premise solutions offer maximum control, security, and customisation options.
Today, many businesses adopt a hybrid strategy to get the best of both worlds: keeping sensitive data on-premise while benefiting from the efficiency of the cloud. The right choice depends on budget, security requirements, and individual business processes. We are here to help you select the most suitable operating model and provide expert advice.
