GigaCloud adopts Cubbit’s DS3 Composer to deliver sovereign, resilient S3 cloud storage to Ukraine and Poland
“Our businesses have learned to think differently: to plan for uncertainty, to value control, and to choose architectures that remain dependable when circumstances change. This partnership with Cubbit helps us turn that experience into a practical storage model for organisations that need not just capacity, but confidence."

GigaCloud is a leading Ukrainian cloud service provider, serving over 20 million users and 1,500 companies across government, defence, finance, media, retail, and IT.
Founded in 2016, the company has been recognised for two consecutive years as Ukraine's best IaaS provider and was the first NVIDIA Solutions Advisor in the country. GigaCloud is the largest partner of the Ukrainian public sector in digital transformation, managing private, public, hybrid, and multicloud environments across its own data centres and an extensive network of partner-operated sites.
As war reshapes infrastructure risks across the region, Ukrainian and Polish organisations increasingly need storage that is resilient to disruption and fully under their own control.
Challenge
Organisations in Ukraine and Poland face an increasingly demanding risk landscape. Ransomware and cyberattacks remain a persistent threat, while armed conflict has made data centre facilities highly susceptible to physical disruption — missile strikes and attacks on critical infrastructure have shown that no single site can be considered safe. If a facility goes offline, organisations lose access to critical systems and productivity halts.
At the same time, companies must comply with an increasingly strict legislative framework — from GDPR to regional laws — while keeping sensitive and strategic data under their direct control, within defined geographic boundaries.
For enterprises, government institutions, and critical infrastructure operators, storage that is resilient, sovereign, and distributed across multiple trusted cross-country sites has moved from a preference to a requirement.
Solution
To meet these requirements, GigaCloud is deploying DS3 Composer — Cubbit's software-defined object storage — across its five data centres spanning three availability zones in Ukraine (Kyiv, Lviv) and Poland (Warsaw).
Data is encrypted, fragmented, and distributed across multiple sites — never exposed in full and always accessible, even if one or more sites experience disruption. Organisations can define precisely where their data resides: within Ukraine only, across both Ukraine and Poland, or in Poland alone, remaining compliant with GDPR and regional regulations throughout.
Each customer benefits from complete tenant isolation, with a dedicated interface and S3-compatible API endpoint giving full control over spaces, access rights, projects, configurations, metrics, reports, and billing. A single intuitive interface unifies control across environments and enables multiple flexible service tiers to be activated simultaneously. Key use cases include immutable backup, disaster recovery, long-term archiving, and the management of unstructured data at scale.
Result
With Cubbit, GigaCloud can provide Ukrainian and Polish organisations with an S3 storage infrastructure distributed across multiple trusted, cross-country sites — keeping strategic data under direct control and continuously available, regardless of what happens to any single facility.
The partnership gives GigaCloud a concrete way to meet the operational demands of its public sector, defence, and enterprise customers: resilience against both cyber and physical disruption, full sovereignty over where data resides, and compliance with GDPR and regional regulations built into the infrastructure itself.
