The cloud in a reality test: What’s really behind the most common assumptions

Cloud computing is now one of the central components of the digital infrastructure in Germany. According to the Bitkom Cloud Report 2025, around 90 percent of German companies use cloud services productively, while the remaining ten percent are actively preparing to get started. At the same time, however, there is a feeling of increasing dependency. More than half of the companies surveyed report that they feel at the mercy of the major providers when it comes to pricing and contract terms. Many of these decisions are the result of myths that persist despite technological advances and distort the real possibilities of the cloud.

One widespread myth concerns the assumption that data automatically becomes sovereign simply because it is stored in a European data center. In practice, sovereignty only arises when companies have full control over keys, data flows and portability. Location alone does not solve this problem. Some large hyperscalers are still subject to foreign legal structures such as the CLOUD Act, which can also be applied to data stored in the EU. Technical mechanisms such as the in-house management of encryption keys, clear data paths within European networks and the ability to transfer data completely and loss-free to other environments are therefore crucial.

The assumption that purely European providers cannot keep up in terms of performance is just as persistent. However, modern architectures in Europe rely on multi-AZ infrastructures with synchronous replication to achieve low latency and stable consistency. Direct peering at major European Internet nodes means that a large proportion of data traffic remains in the European backbone, which prevents additional delays caused by transatlantic detours. This approach results in consistent packet delivery times and reliable performance, which is particularly relevant for applications that process large amounts of data or run AI models in real time.

Another misconception is that the cost of cloud storage hardly differs. The pure price per gigabyte only reflects a small part of the actual costs. A large part of the costs are incurred by data movements, API accesses, transfers between different availability zones and automatic transitions between storage tiers. Without a clear model for determining the total cost of ownership, many cost factors remain undiscovered, which often leads to surprising monthly bills. Transparent price structures make planning much easier here.

The idea that cloud storage is a commodity and that all providers essentially deliver the same product also does not stand up to closer scrutiny. Although many solutions are based on the S3 API, this only defines the interface and not any qualitative requirements. Differences arise in particular in areas such as data consistency, availability, durability or security mechanisms. Functions such as object lock, versioning or event-based notifications are central to protection, automation and audit-proof data storage, but are not implemented in full or in accordance with the standard by all providers. This creates dependencies that can lead to problems in the long term.

Finally, the myth that European providers are not yet suitable for enterprise use remains. In recent years, providers in Europe have caught up massively and now offer infrastructures that are based on international standards. Certifications such as ISO 27001 and SOC 2, decentralized multi-AZ replication, full S3 compatibility without proprietary deviations and comprehensive monitoring mechanisms also enable use in regulated industries. The European cloud is increasingly developing into an independent alternative that combines technical sovereignty and modern architectures.

Conclusion

The main thing I see here is that many misunderstandings are obscuring the real opportunities. The cloud has long been a cornerstone of the digital economy, but is still in a maturing process that presents companies with decisions. 2026 will be measured in particular by how clearly organizations distinguish between dependencies and sovereign, distributed models. Modern European architectures show that performance, data protection and cost clarity can be achieved simultaneously if technical control and transparency are consistently implemented.
