How to eliminate egress fees and achieve full data sovereignty by moving away from traditional pricing models.

Your search for IONOS storage preise highlights a critical need for cost clarity in cloud services. Many enterprises find that initial storage prices are only part of the story, with over 60% of IT leaders exceeding their cloud budgets due to hidden fees like data egress. This article moves beyond a simple price list. It details a modern approach to cloud storage for 2025, focusing on predictable costs, digital sovereignty, and compliance with new EU regulations like the Data Act and NIS-2. We present a checklist for enterprise-ready, EU-centric object storage that eliminates financial surprises and ensures your data remains under your control.

Schlüsselpunkte

  • Traditional cloud pricing is unpredictable, with egress fees making up 10-15% of bills and creating vendor lock-in.
  • True data sovereignty requires a 100% EU-owned and operated provider to avoid CLOUD Act exposure and ensure GDPR compliance.
  • Modern storage platforms are designed for new EU regulations like the Data Act and NIS-2, featuring predictable costs and robust, built-in security.

Deconstruct Traditional Cloud Pricing Models

Traditional cloud storage bills often contain surprises. Egress fees alone can account for 10% to 15% of total cloud costs for many businesses. These charges for moving your own data create significant financial unpredictability.

API call charges add another layer of complexity. A single workflow involving millions of small files can trigger thousands of API calls. This results in costs that are nearly impossible to forecast with 100% accuracy.

High egress costs are a primary driver of vendor lock-in. A five-figure data transfer bill effectively prevents many companies from migrating to a better service. This financial barrier limits your strategic options and negotiating power.

This model directly contrasts with a predictable structure, which is now essential for effective budget management and long-term planning.

Achieve Digital Sovereignty and CLOUD Act Resistance

Data stored with U.S.-based providers is subject to the CLOUD Act, passed in 2018. This allows U.S. authorities to demand access to data, even if it resides in EU data centers. This creates a direct conflict with GDPR's Article 48.

Choosing a 100% European provider eliminates this legal jeopardy. Storing data exclusively in certified EU data centers under EU law provides true cloud storage sovereignty. This is no longer a preference but a core business requirement for many.

Here is how geofencing within the EU ensures compliance:

  • It guarantees data stays within a predefined country or region.
  • It meets strict GDPR data residency requirements for sensitive workloads.
  • It provides a clear legal framework under EU jurisdiction only.
  • It protects intellectual property and trade secrets from foreign legal reach.

Provider origin is now a top-3 selection criterion for EU enterprises. This shift reflects a growing demand for legal certainty and control over critical digital assets.

True sovereignty prepares your architecture for upcoming EU-wide regulations.

Meet 2025 EU Regulations: The Data Act and NIS-2

The EU Data Act, fully applicable from September 12, 2025, mandates easy switching between cloud providers. It requires providers to phase out all switching charges by January 12, 2027, to prevent vendor lock-in. A sovereign S3 storage solution is designed for this portability.

The NIS-2 Directive also introduces stringent new cybersecurity rules. It requires essential entities to implement robust risk management, including supply-chain security and strong encryption. Fines for non-compliance can reach up to 2% of total global revenue.

An enterprise-ready storage platform must include these features for NIS-2 alignment:

  1. Multi-layer encryption for data in transit and at rest.
  2. Immutable storage with Object Lock for ransomware protection.
  3. Granular Identity and Access Management (IAM) with MFA and RBAC.
  4. Operations exclusively within certified, highly secure EU data centers.

Compliance is not an add-on; it is built into the architecture. This proactive stance reduces risk and turns regulatory readiness into a competitive advantage.

This level of built-in security is a key feature of modern object storage.

Demand More: The Enterprise-Ready Checklist

Full S3 API compatibility is the baseline for modern object storage. This ensures your existing backup tools, scripts, and applications work without any code rewrites. It protects your investment in tools like Veeam and others.

Look for an "Always-Hot" storage model. This architecture eliminates complex and fragile tiering, ensuring all data is accessible with zero delay. It avoids the restore fees and API timeouts common with tiered systems.

A first-class console UX is non-negotiable. Your teams should manage buckets, permissions, and lifecycle rules with just a few clicks. This usability reduces reliance on deep API expertise for daily tasks.

True enterprise readiness means no single points of failure. A resilient architecture guarantees high availability and data integrity across multiple availability zones. This is critical for backup, disaster recovery, and archiving use cases.

These technical capabilities are especially valuable for channel partners and MSPs.

Empower Partners and MSPs with Predictable Margins

For MSPs, predictable costs translate directly to predictable margins. A model with zero egress or API fees allows you to build BaaS and archiving services with defensible pricing. You can quote customers for a 3-year term with confidence.

A partner-ready platform provides essential management tools. This includes a multi-tenant console with robust RBAC/MFA and automation via API/CLI. It enables fast onboarding for hundreds of end-customers.

The expanding European distribution network simplifies access. Recent partnerships with distributors like api in Germany and Northamber plc in the UK demonstrate growing channel momentum. This provides local support for resellers across Europe.

This partner-centric approach is designed to fuel growth in a competitive market.

Take Practical Steps Toward a Sovereign Cloud Strategy

Migrating to a sovereign cloud provider is a straightforward process. The first step involves a simple data transfer using S3-compatible tools. Many businesses can complete this initial phase in under 24 hours.

Next, update your application endpoints to the new provider. A fully compatible API means no code changes are needed, just a configuration update. This process typically takes less than 1 hour per application.

Finally, conduct a test restore of a critical backup. This validates the entire workflow and confirms data integrity. A successful test provides 100% confidence in your new disaster recovery plan.

A predictable cost model simplifies every step of this process. You can migrate petabytes of data without facing a massive egress fee from your old provider, making the switch financially viable.

FAQ

What is sovereign cloud storage?

Sovereign cloud storage is a service that stores and processes data exclusively within a specific legal jurisdiction, such as the European Union. It is operated by a provider based in that same jurisdiction, ensuring the data is subject only to local laws like GDPR and is immune to foreign laws like the U.S. CLOUD Act.


Are there really no egress fees or API call costs?

Yes. Impossible Cloud's pricing model is designed for predictability. We do not charge for data egress (outbound data transfer) or for API requests, regardless of volume. Your bill is based on the amount of storage you use, making it simple and transparent.


How does immutable storage protect against ransomware?

Immutable storage, using features like S3 Object Lock, prevents data from being altered or deleted for a specified period. If a ransomware attack occurs, your backups remain untouched and secure, allowing you to restore clean data with 100% integrity instead of paying a ransom.


Is it difficult to migrate from another S3-compatible provider?

No, the migration process is designed to be simple. Because we offer full S3 API compatibility, you can use standard data migration tools to move your data. You only need to update the endpoint and credentials in your existing applications and backup software.


What benefits does this model offer to Managed Service Providers (MSPs)?

For MSPs, a predictable pricing model with no egress fees means stable, defensible margins for services like Backup-as-a-Service (BaaS) and Archiving. The multi-tenant console, automation tools, and expanding European distribution network make it easy to manage clients and scale your business.
