Effective document management is crucial for any organisation seeking efficiency, security and compliance with regulatory requirements. Document management platforms have evolved significantly, offering different deployment models, such as on-premises servers, the cloud and hybrid solutions. This article examines the features, advantages and disadvantages of each approach to help companies choose the option best suited to their needs.
What are document management platforms
Document management platforms are systems that allow documents to be created, stored, organised, retrieved and disposed of digitally. These platforms make it easier to manage large volumes of information, ensuring that documents are secure and accessible when needed. Moreover, as technology has advanced, organisations can deploy these solutions on local servers, in the cloud or through a combination of both, forming a hybrid solution.
On-premises document management platforms
Firstly, on-premises document management solutions involve installing the platform on the company’s own IT infrastructure. In this model, the organisation stores data and documents on physical servers under its full control.
Advantages
- Full control: Companies have complete control over the infrastructure, security and data management.
- Customisation: Greater scope for customisation to meet the organisation’s specific needs.
- Compliance: Makes it easier to comply with regulations that require data to be stored in specific locations.
Disadvantages
- High cost: Requires significant upfront investment in hardware, software and maintenance.
- Complex maintenance: Responsibility for maintaining and updating the systems lies entirely with the company.
- Limited scalability: Increasing capacity can be costly and time-consuming, as new servers have to be purchased.
Cloud document management platforms
On the other hand, cloud-based solutions involve storing and managing documents on remote servers accessible over the internet. This model has become increasingly popular thanks to its flexibility and cost-effectiveness.
Advantages
- Scalability: Easy to scale as the company grows, adding or reducing resources as needed.
- Remote access: Users can access documents from anywhere, at any time, provided they have an internet connection.
- Lower cost: Removes the need for heavy investment in local infrastructure, running on a pay-as-you-go model.
Disadvantages
- Internet dependency: Access to documents depends on a stable internet connection.
- Security and compliance: Concerns may arise about data security and regulatory compliance, especially in highly regulated sectors.
- Less control: Companies have less control over where and how data is stored, as they depend on the cloud service provider.
Hybrid document management platforms
Finally, hybrid solutions combine both models, allowing companies to use both local servers and the cloud for document management. In this way, the organisation can keep certain documents locally and manage others in the cloud.
Advantages
- Flexibility: Companies can choose where to store different types of documents, according to their importance and sensitivity.
- Cost-effectiveness: Costs can be optimised by using the cloud for scalable storage and local servers for critical data.
- Business continuity: If the local infrastructure fails, the cloud can act as a backup, ensuring that operations continue.
Disadvantages
- Management complexity: Managing a hybrid solution can be more complex, requiring effective integration between local systems and cloud services.
- Implementation cost: Although it may be more economical in the long term, the initial set-up of a hybrid solution can be expensive.
- Security and compliance: In addition, the need to ensure security and compliance across two different environments can increase complexity.
Choosing between deployment models for your company
In short, the choice between an on-premises, cloud or hybrid solution depends on several factors, including company size, budget, compliance needs and security requirements. The most important considerations include:
- Company size and growth: Small businesses can benefit from the scalability and low cost of cloud solutions, while large organisations with complex needs may prefer on-premises or hybrid solutions.
- Security requirements: Companies handling highly sensitive data may opt for on-premises or hybrid solutions, which give them greater control over security.
- Regulatory compliance: Check the legal requirements for your sector. For example, some regulations may require certain data to be stored locally.
- Budget: Assess the budget available for implementation and maintenance. Cloud solutions offer lower upfront costs, whereas on-premises solutions may require greater investment.
SaaS, private cloud and self-hosting
Within the cloud, in turn, there are several options. In the SaaS model, the provider manages the application, the infrastructure and updates, and the company simply uses the service. On the other hand, with a private cloud or dedicated hosting, the company has more control over the configuration, but also more responsibilities. For most small and medium-sized businesses, therefore, SaaS is the simplest option, provided the provider offers adequate guarantees of security and data protection.
Data protection and location
In any cloud model, the provider acts as a processor. For this reason, the GDPR requires a contract with the clauses of Article 28, which set out the processing instructions, security measures, sub-processors and the return or deletion of data at the end of the contract. In addition, it is worth knowing where the data is hosted. When it is outside the European Economic Area, the rules on international transfers apply. Meanwhile, the European Data Act has made it easier to switch between cloud service providers, progressively reducing exit costs.
Total cost of each model
| Component | On-premises server | Cloud (SaaS) |
|---|---|---|
| Initial investment | High: servers, licences and installation | Low: configuration and migration |
| Recurring costs | Energy, maintenance, backups and technical staff | Subscription |
| Updates and security | Company’s responsibility | Mainly the provider’s responsibility |
| Scalability | Requires new equipment | Adjusting the contracted plan |
Security and the supply chain
The choice of model also has cybersecurity implications. On the one hand, with a local server, the company is responsible for applying updates, monitoring access and testing backups. On the other hand, in the cloud, these tasks largely pass to the provider, but the company remains responsible for user management, permissions and multi-factor authentication. In addition, the NIS 2 Directive requires the entities it covers to assess the security of their suppliers. It is therefore advisable to ask for concrete evidence, such as ISO/IEC 27001 certificates, audit reports and continuity plans, before signing the contract.
It is also important to confirm the availability guaranteed in the contract, support response times and the procedure in the event of an incident. That way, the company knows exactly what to expect from the provider.
Practical example: Migrating from a local server
Consider a company with a ten-year-old file server and no off-site backups. After assessing the costs and risks, the company decides to migrate to a SaaS platform hosted in the European Union. First, it classifies its documents and removes duplicates. Next, it migrates the active documents and keeps the old server for reference only for six months. As a result, it reduces maintenance costs and gains backups managed by the provider.
Checklist for choosing a model
- Security and compliance requirements identified.
- Total cost calculated over three or five years.
- Data location and sub-processors known.
- GDPR data processing agreement signed.
- Exit plan and data export defined.
Common mistakes to avoid
A frequent mistake is comparing only the subscription price with the cost of the server, forgetting maintenance, energy and staff time. Another mistake is choosing the cloud without checking where the data is kept. In addition, many companies do not plan how to recover their documents if they change provider.

Frequently asked questions
Is the cloud less secure than a local server?
Not necessarily. In fact, a certified provider generally has more security resources than a small business. However, you need to check certifications, contracts and data location.
Can we start in the cloud and switch later?
Yes, provided the contract guarantees full export of documents and metadata in an open format. It is therefore worth checking this point before signing.
Conclusion
Document management platforms are fundamental to organising and securing information in companies. However, the choice between local servers, the cloud or hybrid solutions depends on a careful analysis of the organisation’s specific needs. Each option has its own advantages and challenges, and the right decision can significantly improve the organisation’s efficiency, security and compliance.
