Move beyond unpredictable hyperscaler costs and regulatory risks with a European cloud storage solution built for performance, sovereignty, and transparent economics.

In 2025, cloud reliance is nearly universal, but so are the pain points of vendor lock-in and surprise costs. Many IT leaders feel trapped by complex pricing, with a significant share preferring a European provider for better data governance. This article outlines a clear path to a more affordable and compliant cloud storage strategy. We explore a leading European alternative that eliminates egress fees and API call costs entirely, offering full S3 compatibility and robust ransomware protection. It's a sovereign-by-design solution for enterprises and MSPs seeking control.

Schlüsselpunkte

  • Eliminate unpredictable cloud storage costs by choosing a provider with zero egress fees, no API call charges, and no minimum storage durations.
  • Achieve true digital sovereignty and GDPR compliance by using a European cloud that operates exclusively in EU data centers, avoiding CLOUD Act exposure.
  • Strengthen ransomware protection and simplify operations with an 'Always-Hot,' S3-compatible architecture featuring immutable Object Lock.

Eliminate Unpredictable Cloud Costs by Design

Most cloud providers' pricing models create significant financial uncertainty for IT departments. A 2025 study found 95% of organizations experience unexpected cloud storage charges from fees for data egress and API calls. These variable costs make budget forecasting for data-intensive workloads like backup and disaster recovery nearly impossible. An alternative model completely removes these punitive charges. This predictable-by-design approach means zero egress fees, zero API call costs, and no minimum storage duration. This shift gives Managed Service Providers (MSPs) the ability to secure predictable margins for their BaaS and archiving services. It provides a stable foundation for financial planning, a clear advantage over the hyperscaler status quo.

Achieve Digital Sovereignty and CLOUD Act Avoidance

Data sovereignty is a primary concern for over 80% of EU decision-makers. Storing data with non-EU providers creates exposure to foreign laws like the U.S. CLOUD Act, which can compel access to European data regardless of its physical location. A truly sovereign solution operates exclusively in certified European data centers. This ensures all data remains under strict EU legal governance, aligning with GDPR from the ground up. With features like country-level geofencing, organizations in regulated sectors such as financial services can guarantee data stays within predefined regions. This architecture provides the legal certainty that many enterprises now demand.

Leverage Full S3 Compatibility Without Reworking Pipelines

Migrating to a new storage platform often carries the risk of costly application rewrites and workflow disruptions. Full S3-API compatibility eliminates this barrier, protecting past investments in scripts, tools, and applications. This goes beyond basic object operations to include advanced capabilities. The goal is 100% continuity for existing tools and SDKs. A fully compatible platform supports:

  • Standard object operations via API, CLI, and SDK.
  • Advanced features like versioning and lifecycle management.
  • Out-of-the-box integrations with leading backup tools like NovaBackup.
  • Event notifications to trigger automated downstream processes.

This ensures a seamless transition, allowing IT teams to switch endpoints with zero code changes. This approach minimizes migration risk and preserves years of operational knowledge.

Adopt an 'Always-Hot' Architecture for Superior Performance

Complex storage tiering introduces delays, restore fees, and operational fragility. An "Always-Hot" object storage model ensures all data is immediately accessible with predictable latencies, eliminating the hidden costs and API timeouts associated with restoring data from archival tiers. This architecture is built for consistency and availability, using multi-AZ replication to prevent single points of failure. Every object is treated as critical, avoiding the performance penalties of tiered systems. This simplifies operations for use cases handling millions of small files or hybrid analytic workloads. It guarantees that when you need your data for a restore or audit, it is available in milliseconds.

Strengthen Ransomware Defense with Immutable Storage

Ransomware remains a top threat, making immutable backups a critical defense layer. Using S3 Object Lock, organizations can make their backup data unchangeable for a defined period, rendering it safe from malicious encryption or deletion. This write-once-read-many (WORM) model is a core component of a modern 4-2-2 or 3-2-1 backup strategy. The security posture is further enhanced with multi-layer encryption (in transit and at rest) and granular Identity and Access Management (IAM). These controls, including MFA and RBAC, ensure only authorized personnel can access sensitive data. This provides an audit-ready retention system that strengthens your overall ransomware protection posture.

Prepare for the EU Data Act and NIS-2 Regulations

Upcoming EU regulations create new compliance burdens that a sovereign cloud architecture addresses by design. The EU Data Act, effective from September 2025, mandates data portability to prevent vendor lock-in. A standards-based platform with exportable formats proves a real exit path is always available. The NIS-2 Directive requires continuous security processes and supply-chain assurance for critical infrastructure. An EU-centric provider bakes these requirements into its operations, offering patch management and documented incident reporting timelines. This regulatory readiness becomes a competitive advantage, not an afterthought. Choosing a compliant platform simplifies adherence to these evolving European standards.

Empower MSPs and Channel Partners with a Predictable Model

For MSPs and resellers, margin predictability is everything. The zero-egress, zero-API-fee model provides a stable economic foundation for building profitable services like Backup-as-a-Service and archiving. A partner-ready platform accelerates growth with essential tools. These features are designed for rapid onboarding and efficient scaling:

  1. A multi-tenant console with robust RBAC and MFA.
  2. Full automation capabilities via a comprehensive API and CLI.
  3. Detailed reporting for client management and billing.
  4. Expanded local access through distributors like api in Germany and Northamber plc in the UK.

This ecosystem focus ensures partners can deliver value to their clients without risking their own profitability on unpredictable cloud costs.

Your Next Steps Toward a Sovereign and Affordable Cloud

Switching to a European cloud alternative is a practical step toward gaining cost control and digital sovereignty. The process begins with identifying workloads burdened by high egress fees, such as backup, disaster recovery, or archiving. An S3-compatible platform allows for a simple migration; you only need to update the endpoint and credentials in your existing tools. Test restores and data validation are simplified with an always-hot architecture, ensuring 100% of your data is immediately available. To see the benefits firsthand, you can talk to an expert.

FAQ

What are the main advantages of a cloud storage solution with no egress fees?

The primary advantage is cost predictability. Without egress fees or API call charges, you can accurately forecast your storage expenses, especially for data-intensive use cases like backup, disaster recovery, and media distribution. It also prevents vendor lock-in by removing the financial penalty for moving your data.


How does Object Lock protect against ransomware?

Object Lock applies a write-once-read-many (WORM) model to your data, making it immutable for a specified retention period. This means that once data is written, it cannot be altered, encrypted, or deleted by anyone, including ransomware, until the lock expires. It is a critical defense for securing backups.


Is this type of storage suitable for Managed Service Providers (MSPs)?

Absolutely. A predictable pricing model allows MSPs to build profitable Backup-as-a-Service (BaaS) and Archiving-as-a-Service offerings with stable margins. Features like a multi-tenant console, automation via API/CLI, and detailed reporting are specifically designed to help partners manage their clients efficiently.


What does digital sovereignty mean in the context of cloud storage?

Digital sovereignty means your data is subject only to the laws and governance of the jurisdiction where it is stored. For European businesses, this means using a cloud provider that operates exclusively within the EU, ensuring data is protected by regulations like GDPR and is not subject to foreign laws such as the U.S. CLOUD Act.


What is the benefit of an 'Always-Hot' storage model over tiered storage?

An 'Always-Hot' model simplifies operations and guarantees immediate data access with no restore delays or retrieval fees. Tiered storage often introduces complexity and hidden costs when you need to access archived data, which can cause application timeouts and budget overruns. The 'Always-Hot' approach ensures all data is equally accessible and performant.


How does this storage solution align with the new EU Data Act?

The solution aligns with the EU Data Act's goal of preventing vendor lock-in by design. With no egress fees, full S3 compatibility, and the use of open standards, it provides a clear and economically viable exit strategy, ensuring customers can always move their data freely, as the regulation requires from September 2025.
