en.Wedoany.com Reported - Ukrainian cloud service provider GigaCloud has formed an alliance with Italian geo-distributed storage company Cubbit to create an S3-compatible distributed storage infrastructure for enterprises and institutions in Ukraine and Poland. The platform's data will be distributed across five data centers located in Kyiv, Lviv, and Warsaw, allowing organizations to decide where their data is stored while ensuring availability in the event of one or more site outages.

This collaboration reflects a shift in the European market's understanding of digital sovereignty. In a war scenario, the physical location of data becomes a decisive factor for business continuity. Digital sovereignty no longer merely means that information resides within specific borders; it also encompasses control over encryption keys, technological autonomy, portability, and the ability to withstand large-scale failures, particularly requiring architectures designed to maintain essential services even when physical facilities suddenly become inaccessible.

The conflict in Ukraine has shaken traditional protection strategies that view data centers as stable sanctuaries. Missile strikes, power outages, communication disruptions, and damage to critical infrastructure have demonstrated that no single site offers absolute security. The model chosen by GigaCloud and Cubbit is designed to meet this need: data is encrypted, sharded, and distributed across different nodes, with no single site holding complete information. When one site is unavailable, the system reconstructs content from remaining accessible fragments, reducing reliance on a single physical location and transforming resilience from an added feature into a structural characteristic of the architecture. This principle applies not only to countries facing conflict but also to European operators dealing with extreme climate events, energy crises, or coordinated attacks.

GigaCloud will integrate Cubbit DS3 Composer into its five data centers, distributed across three availability zones: Kyiv and Lviv in Ukraine, and Warsaw in Poland. Customers can choose different data residency strategies, keeping information solely within Ukraine, distributing it between the two countries, or retaining it only in Poland. This choice determines the applicable legal framework and exposure to local risks. Each customer will have an isolated tenant environment with dedicated interfaces and S3-compatible API endpoints to manage storage capacity, access permissions, projects, configurations, metrics, reports, and billing. The S3 standard, introduced by Amazon Web Services in 2006, facilitates integration with existing applications and reduces lock-in risk.

In European discussions, sovereign clouds are often associated with data localization, but keeping information within national borders does not automatically guarantee effective control. Enterprises may use local infrastructure while still relying on proprietary software or technologies that are difficult to replace. This collaboration aims to combine operational autonomy with geographic residency: customers define where data resides and maintain control over configurations through independent environments. Sharding technology prevents any single infrastructure from accessing complete content, creating a model closer to operational autonomy. This evolution particularly involves public administrations, defense, finance, and critical infrastructure operators, where sovereignty becomes a prerequisite for ensuring the availability of essential services and complying with regulatory obligations, with the General Data Protection Regulation (GDPR) remaining a core reference.

The agreement also demonstrates a shift in disaster recovery approaches. Geo-distributed systems embed fault tolerance into daily storage management, with information distributed from the outset so that recovery and reconstruction are possible even when some components are unresponsive. Use cases cited include immutable backups, disaster recovery, long-term archiving, and unstructured data management. Immutable backups are especially important against ransomware, preventing modification or deletion of copies during an attack. Geographic distribution protects against physical disruptions, and the combination addresses different threats. Distributed infrastructure allows for more consistent design of recovery time objectives (RTO) and recovery point objectives (RPO) based on service criticality.

Target markets include large and medium-sized customers, with a particular focus on the public sector, government agencies, and defense, as well as financial services, media, retail, and IT. GigaCloud claims to serve over 1,500 organizations and 20 million users, managing private, public, hybrid, and multi-cloud infrastructures. Cubbit will support the cloud service provider through training, commercial support, and joint marketing activities. The agreement also includes service level agreement (SLA) standards, technical support, and service quality. Cubbit's technology has been adopted by over 400 enterprises and operators, including Leonardo and Rai Way.

Stefano Onofri, co-CEO and co-founder of Cubbit, stated that the project is directly linked to the need to protect Ukraine's digital infrastructure, bringing a geo-distributed storage infrastructure that safeguards strategic data and keeps it always available. This is a by-design architecture aimed at distributing data across multiple reliable countries so that, under the most critical conditions, data remains online and under the control of its true owners. Nazariy Kurochko, CEO and co-founder of GigaCloud, emphasized that cloud infrastructure in the region cannot be designed based on the logic of more stable markets. Enterprises have learned to plan with uncertainty in mind, prioritize control, and choose architectures that remain reliable even as circumstances change. This collaboration translates that experience into a concrete storage model and represents a step toward strengthening the European cloud ecosystem.

This partnership can be interpreted as a local response to exceptional circumstances, but its strategic value concerns the entire European market. Increasing cyber threats, geopolitical tensions, and the concentration of services among a few global operators are driving enterprises and governments to reassess their choices. The priority is to build interoperable, distributed, and governable infrastructures that avoid dependencies making supplier switching difficult. The S3 standard allows connecting tools and applications developed by different entities, and distributing data across multiple reliable countries enhances resilience without sacrificing compliance. Sovereignty thus takes on a European dimension, where the real challenge is no longer merely preserving information but keeping it available, verifiable, and governable as the entire operational environment changes.
