A strong majority of EU decision-makers now demand European solutions for critical data infrastructure. The challenge is finding a platform that delivers on sovereignty, GDPR compliance, and cost transparency without complex migrations. S3-compatible REST APIs are the key, allowing businesses to use existing tools and scripts while securing data within EU borders. This approach eliminates CLOUD Act exposure and provides the regulatory certainty needed for sensitive workloads. Impossible Cloud offers a sovereign-by-design object storage solution with a predictable cost model, making it a practical, enterprise-ready EU alternative.
Key Takeaways
- Impossible Cloud provides a GDPR-compliant, S3-compatible REST API storage solution designed for digital sovereignty in Europe.
- The platform features a predictable cost model with no egress fees, no API call costs, and no minimum storage durations.
- Advanced features include an "Always-Hot" architecture, Immutable Object Lock for ransomware protection, and readiness for the EU Data Act and NIS-2 directive.
Achieve Full S3 Compatibility for Seamless Integration
True S3 compatibility goes beyond basic operations. Our platform supports advanced capabilities like versioning and lifecycle management across any API, CLI, or SDK. This protects your past investments in tools and training, with 100% of applications running without code rewrites. This minimizes migration risk to near zero. You can explore our S3 API implementation to see how existing pipelines keep working. This ensures your transition to a sovereign cloud is seamless and efficient.
Utilise an Architecture Built for 100% Availability
Our architecture delivers strong read/write consistency and predictable latencies for any workload. We use an “Always-Hot” object storage model, ensuring all data is immediately accessible with zero tier-restore delays. This avoids the hidden operational costs and API timeouts common with fragile tiering policies. This model simplifies operations by at least 30%. Here is how our architecture ensures resilience:
- Multi-AZ replication eliminates single points of failure.
- Predictable latencies support millions of small files or large archives.
- The model keeps third-party backup tools stable and performant.
- It avoids lifecycle policy drift, which can cause restore failures.
This robust foundation provides the stability needed for mission-critical API performance and data integrity.
Implement Governance That Mirrors Your Organisation
Identity-based IAM with granular, role-driven policies is standard. We support external IdPs via SAML/OIDC for streamlined user management. Our platform offers a first-class console UX for bucket management, role assignment, and object tagging without deep API expertise. This reduces administrative overhead by up to 40%. You can learn more about securing your data with our API security guide. This focus on usability ensures your teams can manage storage efficiently and securely.
Gain a Competitive Advantage with Regulatory Readiness
Our platform is designed for compliance with key EU regulations. We operate exclusively in certified EU data centers, aligning with GDPR and geofencing requirements. This readiness for upcoming regulations gives your business a distinct advantage. Here are two key regulations we address:
- EU Data Act (from September 2025): We provide data portability by design, including metadata and versions, proving a real exit path with no lock-in.
- NIS-2 Directive: Our operations include continuous security processes, patch management, and supply-chain assurance, meeting the directive's stringent requirements.
This proactive approach to compliance, including features like RESTful API design, turns regulatory obligations into a strategic asset.
Leverage Economics That Hold Under Enterprise Load
Our transparent model features zero egress fees, no API call costs, and no minimum storage durations. This predictability is essential for business planning, with customers seeing total cost of ownership reductions of over 50%. Guaranteed service levels ensure performance never degrades. We demonstrate scalable handling of large object sets with steady API performance over time. This economic clarity is central to our API-first storage philosophy. It provides a stable foundation for growth without financial surprises.
Empower MSPs with a Partner-Ready Platform
For our partners, predictable margins are designed in. The zero-egress-fee model allows MSPs to offer BaaS and archiving with stable, defensible pricing. Our multi-tenant console includes RBAC and MFA for secure client management. We provide full automation via API/CLI and clear reporting tools. With distributors like api (Germany) and Northamber plc (UK), we are expanding local access for resellers. This makes it simple to integrate our object storage programming into your services.
Protect Your Data with Immutable, Ransomware-Proof Storage
Security is at the core of our platform. We provide multi-layer encryption for data in transit and at rest. Our Immutable Storage with Object Lock is a key defense against ransomware, ensuring backups cannot be altered or deleted for a defined period. This feature is critical for meeting audit-ready retention policies. This can reduce ransomware recovery times by over 90%. Implementing these API security best practices is simple. This resilience ensures your business can recover quickly from any threat.
Build Modern Applications on Sovereign Infrastructure
Developers need reliable, fast, and compliant infrastructure. Our S3-compatible REST APIs allow you to build and deploy applications without worrying about the underlying storage complexities. The “Always-Hot” model guarantees that all data is instantly available, which is critical for dynamic web applications. This can improve application response times by up to 60%. Our platform is the best object storage for web applications requiring EU data residency. This frees your team to focus on innovation, not infrastructure management.
