Is Leviia object storage the best Amazon S3 alternative?

Résumé

Resume : Organizations storing data with US-based providers — AWS S3, Azure Blob Storage, Google Cloud Storage, or Wasabi — are exposed to American extraterritorial laws: the Cloud Act, Patriot Act, and FISA allow federal agencies to access data stored anywhere in the world, without prior notification. This applies to any organization that values the confidentiality and legal control of its data, not only those in regulated industries. European sovereign alternatives include OVHcloud, Scaleway, and Leviia Storag3 — all hosted in France, ISO 27001 and HDS certified, geo-distributed across 3 sites, and outside US jurisdiction. Leviia Storag3 is S3-compatible, priced at €9.99/TB with no egress fees and no early deletion fees — compared to ~€22/TB storage plus ~€85/TB egress at AWS S3.

The object storage service market has long been dominated by Amazon S3 (Simple Storage Service), Amazon’s flagship solution for cloud storage. Considered the “market standard,” it’s not without its flaws. What are its main weaknesses? How does Leviia position itself as a viable alternative to Amazon S3 for object storage?

This article is especially relevant for organizations looking to optimize their cloud infrastructure for better performance, cost-efficiency, and sovereignty, without compromising on scalability and performance or compliance.

The two major flaws of Amazon S3

First, Amazon S3 is a U.S.based solution and cannot fully guarantee the privacy of its users’ data. Subject to U.S. jurisdiction, Amazon is bound by the Cloud Act and the Patriot Act. These laws require U.S. companies to hand over user data to authorities or federal agencies upon request, even if the data is hosted in France or elsewhere in Europe.

There are strong suspicions that these laws are used to access data improperly, conduct economic espionage, or steal intellectual property. This raises real concerns about AWS security and compliance, especially for businesses operating under European regulations like the GDPR.

As a result, no U.S. based object storage service, whether Amazon S3, Azure Blob Storage (Microsoft), Google Cloud Storage, Backblaze, or Wasabi, can fully ensure the data governance or data protection your company needs.

In contrast, Leviia offers a 100% sovereign object storage service, fully hosted and operated in France.

The second weakness of Amazon S3 is its pricing. The pricing page for S3 storage classes is notoriously complex and difficult to navigate, featuring eight different plans and about fifteen different rates (in USD) depending on the country. In summary, the standard price for Amazon S3 is approximately $22 per terabyte per month for storage, plus $85 per terabyte for outbound traffic. This is a steep cost, which can become astronomical for companies handling large volumes of data.

Leviia’s object storage solution is far more affordable, costing 80% less. Its transparent model also avoids the confusion around S3 Intelligent-Tiering, S3 Glacier storage classes, or data transfer acceleration fees that can inflate the final bill.

Object Storage: sovereign cloud solutions

If data availability and durability are critical for your business, a sovereign cloud storage solution is the way to go. These are solutions developed by French companies, subject to French jurisdiction. A sovereign object storage service not only hosts data on French soil but also ensures that every step of the data lifecycle management process is handled by a French entity. This keeps your data out of reach of foreign laws and cross-region replication issues tied to U.S.-based providers.

Several providers offer sovereign object storage services. OVH Cloud, a long-standing player in the French cloud market, provides a dedicated object storage service. Scaleway, a hosting company founded by Xavier Niel in the early 2000s, also offers a similar solution.

However, these solutions come with high costs: OVH Cloud charges around $25 per terabyte, and Scaleway charges $14.60 per terabyte, not including API access or outbound traffic fees.

The strengths of Leviia Storag3: the best french alternative to AWS

Leviia Storag3 stands out in the S3 object storage market by combining advanced security with budget control.

While major U.S. players like AWS charge high prices, use opaque pricing structures, and offer no sovereignty, alternatives like Wasabi often focus on low costs at the expense of replication and data protection, compliance, and long-term scalability. Leviia Storag3 is the only sovereign S3-compatible solution that balances security, compliance, and affordability.

1. Pricing: full cost transparency

Leviia Storag3 offers a clear and accessible pricing structure:

  • Up to 70% savings compared to AWS S3, with billing per terabyte for predictable expenses.
  • No hidden fees: no egress costs, no deletion fees, and no charges for API access, what you see is what you pay.
  • Unlike cost-effective storage classes that often hide fees behind complex rules, Leviia keeps pricing flat and understandable.

2. Security and sovereignty: maximum data protection

Leviia Storag3 is designed to provide top-tier security and sovereignty:

  • Data is intelligently distributed across three distinct remote data centers in France using erasure coding, ensuring exceptional data durability and fault tolerance.
  • Even if one site fails (due to an incident, disaster recovery scenario, or attack), all data remains accessible.
  • Exclusively French hosting: data is stored solely on French territory, safe from extraterritorial laws like the Cloud Act or FISA.
  • Leviia holds ISO 27001 and HDS certifications, ensuring AWS security and compliance, level guarantees in a fully sovereign environment.
  • Guaranteed privacy: no third-party, commercial, or advertising access to stored data is possible.

3. A complete and high-performing S3 solution

Leviia Storag3 meets all object storage needs:

  • Full compatibility with the S3 API and all major backup and restore strategies, including Veeam, Acronis, Bacula, Commvault, Atempo, QNAP, Synology, and more.
  • It is also ideal for cloud-native applications that require scalable, resilient, and API-driven storage.
  • An intuitive interface for setting S3 bucket policies, managing IAM roles, monitoring buckets, quotas, and advanced configurations. Leviia’s IAM support is fully compatible with AWS Identity and Access Management models for fine-grained permission control.
  • Enhanced application security: HTTPS encryption, S3 versioning, and the Object Lock feature to mitigate ransomware or accidental deletions.
  • Advanced tools such as S3 Inventory reports, event notifications with S3, and server access logging for S3 ensure full auditability and transparency.
  • Support for S3 lifecycle policies allows automated data tiering, expiration, and archiving in compliance with retention strategies.
  • Advanced metadata management enables efficient file indexing, search, and classification at scale, critical for enterprise workloads.
  • Exceptional durability rate: 99.999999999% (11 nines), reflecting enterprise-grade data availability and durability.

Comparison table: S3 object storage providers ranked by sovereignty, security and total cost

Choosing a sovereign alternative to AWS S3 means evaluating more than storage price. The real cost includes egress fees on every restore or data transfer, and the security level of the infrastructure matters: geo-distribution, certifications, and legal control over data. Wasabi is the cheapest option in this table, but also the one with the fewest security guarantees: single-site infrastructure, no HDS certification, and subject to US extraterritorial laws.

Frequently asked questions (FAQ)

Sovereign alternatives to AWS S3 hosted in France and outside US jurisdiction include OVHcloud, Scaleway, and Leviia Storag3. All three are ISO 27001 and HDS certified, and geo-distributed across 3 sites. Leviia Storag3 has no egress fees and no early deletion fees, at €9.99/TB.
Wasabi is ISO 27001 certified since June 2025 and supports Object Lock. However, its infrastructure is single-site with no multi-site geo-distribution, it is not HDS certified, and it is subject to US extraterritorial laws. It is the cheapest option on the market (€6.99/TB) but also the one with the fewest guarantees in terms of resilience, French compliance, and data sovereignty.
Data sovereignty means the data cannot be accessed by foreign governments via extraterritorial laws. US companies (AWS, Wasabi, Microsoft, Google) are subject to the Cloud Act and Patriot Act. This matters for any organization that values confidentiality and legal control of its data, not only regulated industries. French providers (OVHcloud, Scaleway, Leviia) are not subject to these laws.
Yes. Leviia Storag3 is 100% S3-API compatible. Migration from AWS S3 only requires updating the endpoint URL and access credentials, no code changes needed.
