Cloud hosting for companies in 2025

Cloud hosting offers companies the opportunity to use IT resources flexibly and in line with their needs. The cloud is a particularly attractive solution for digital companies: it enables rapid scaling with increasing document volumes, reduces investment costs and guarantees high availability.

Choosing the right cloud hosting model depends on various factors - from security requirements and compliance specifications to budget and scaling requirements. There are various options available to companies: Public cloud, private cloud or hybrid models.

In this article, you will find out which cloud hosting models are suitable for document processing and what companies should look out for when making their choice.

What is cloud hosting?

Cloud hosting refers to the provision of IT resources via the internet. Instead of operating their own servers, companies use the computing power, storage and network capacities of cloud providers. The resources are provided and billed as required.

Cloud hosting is particularly attractive for AI applications, as machine learning models require high computing power - not constantly, however, but primarily during training phases or peak loads. The cloud makes it possible to use these resources flexibly and only pay for them when needed. This leads to a significantly more efficient use of resources compared to static on-premise infrastructures.

Cloud hosting models at a glance

Public Cloud

The public cloud uses shared infrastructure from several cloud providers such as AWS, Microsoft Azure or Google Cloud. Resources are provided via the internet and shared with other customers. This approach enables particularly fast provisioning without the need to purchase your own hardware, as the providers take care of automatic updates and maintenance.

Global availability and flexible scaling make the public cloud particularly attractive for start-ups, companies with variable workloads and projects that need to be implemented quickly. The costs are based on actual usage, which makes it easier to get started, especially at the beginning of a project.

Private Cloud

The Private Cloud offers dedicated resources for a single company. The infrastructure can be operated either in the company's own data center or by a hosting provider. Companies retain full control over their data and infrastructure. Higher security standards can be implemented and the configurations can be customized.

Banks, insurance companies, healthcare facilities and public authorities in particular rely on private clouds when regulatory requirements or data sensitivity demand it. The resources are not shared with other users, which ensures predictable performance.

Hybrid Cloud

The Hybrid Cloud combines public and private cloud. Sensitive data remains in the private cloud, while less critical workloads run in the public cloud. This flexibility by combining different models enables optimum cost efficiency.

Companies can scale into the public cloud during peak loads while maintaining data sovereignty for sensitive information. This model is particularly suitable for medium-sized to large companies with mixed requirements that need both flexibility and control.

Scalability and performance

One of the greatest strengths of cloud hosting is automatic scaling. Document processing systems can dynamically adapt their capacity to the current load. A practical example: in normal operation, a company processes around 100 invoices per day with three server instances. At the end of the month, the volume increases to 2,000 invoices per day, whereupon the system automatically scales up to 15 instances. Once processing is complete, the system automatically scales back to the original three instances.

This flexibility is particularly valuable for companies with seasonal fluctuations or continuously growing document volumes. The automatic adjustment typically takes place within seconds to minutes, without manual intervention.

Cost models in comparison

Cloud hosting follows the pay-per-use principle: costs are only incurred for resources that are actually used. Compared to on-premise servers, there are no high acquisition costs. A typical server for document processing costs between 8,000 and 15,000 euros to purchase, plus monthly operating costs of 200 to 400 euros.

Cloud hosting does not incur any acquisition costs, but monthly usage fees of around 500 to 1,500 euros, depending on the volume. Scaling is automatic, whereas with on-premise, new hardware has to be procured. Maintenance and updates are already included in cloud hosting.

The break-even point between cloud and on-premise is typically 12 to 24 months, depending on the intensity of use and the cloud model selected. You can find more details on the cost comparison in our article On-premise vs. cloud.

GDPR and data protection

GDPR compliance is crucial for German companies. Cloud hosting can be GDPR-compliant if certain requirements are met. The data center location plays a key role here: data should be stored in EU data centers. Many providers offer German locations, such as AWS Frankfurt or Azure Germany.

An order processing contract must be concluded with the cloud provider in accordance with Art. 28 GDPR. This regulates the processing of personal data and ensures that the provider complies with the GDPR requirements. Encryption should be guaranteed both during data transmission and at rest. Companies also need clear regulations on access control.

Regulated industries in particular, such as banks, insurance companies and the healthcare sector, often rely on Private Cloud-solutions or hybrid models to retain maximum control over their data and meet specific compliance requirements.

Frequently asked questions

What does cloud hosting for document processing cost?

The costs vary greatly depending on the document volume and the model selected. A typical production environment costs between 500 and 2,000 euros per month. Decisive factors are the number of documents, required computing power and storage volume. Precise cost estimates should be prepared on the basis of the individual usage profile.

Is cloud hosting GDPR-compliant?

Yes, if the data is hosted in EU data centers and an order processing contract is in place. Many cloud providers offer GDPR-compliant data centers in Germany. It is important that data processing is fully documented and that technical and organizational measures are implemented in accordance with the GDPR.

Which cloud provider is best suited?

It depends on the individual requirements. AWS offers the greater variety of services, Azure integrates well into Microsoft environments and Google Cloud is often more cost-effective. For maximum data sovereignty, German providers such as the Open Telekom Cloud are an option. The choice should be made on the basis of compliance requirements, budget and technical requirements.

How long does the switch to cloud hosting take?

A test instance can be set up within a few hours. Four to six weeks should be planned for productive environments, including the migration of existing data and integration into existing systems. The exact duration depends on the scope of the infrastructure to be migrated.

Is it possible to switch back to on-premise?

Yes, modern container-based architectures enable a flexible switch. The migration from cloud to on-premise typically takes two to four weeks. You can find more details on the migration process in the article Cloud migration.
