GigaCloud and Cubbit launch sovereign cloud storage for Ukraine and Poland

Partnership will distribute critical data across sites in Kyiv, Lviv and Warsaw to protect organisations from cyberattacks and physical disruption

Ukrainian cloud provider GigaCloud has partnered with Italian storage company Cubbit to launch sovereign cloud storage services for organisations in Ukraine and Poland.

The partnership will use Cubbit’s DS3 Composer software-defined object storage across five GigaCloud data centres in three availability zones in Kyiv, Lviv and Warsaw, according to a statement.

The companies said the system is designed to keep critical data available even if one or more sites are disrupted by cyberattacks, ransomware, missile strikes or failures in critical infrastructure.

The service will allow organisations to decide where their data is held, either within Ukraine, across Ukraine and Poland, or in Poland alone.

GigaCloud and Cubbit said the arrangement is aimed at enterprises, government bodies and critical infrastructure operators that need data sovereignty, resilience and compliance with GDPR and regional regulations.

Cubbit’s technology encrypts, fragments and distributes data across multiple sites so that files are not exposed in full at any one location.

Stefano Onofri, co-founder and co-chief executive of Cubbit, said: “We are proud to bring our technology to Ukraine and support the country at a moment when the resilience of digital infrastructure has never mattered more.

“GigaCloud is firmly rooted in the local market, trusted by government institutions and critical infrastructure operators, and brings deep technical expertise.

“Together, we are giving Ukrainian and Polish organisations something new to these regions: a geo-distributed storage infrastructure that keeps strategic data protected and always available — distributed across multiple trusted countries by design, so that even in the most demanding conditions, data remains online and in the hands of those who own it.”

The companies said customers will receive tenant isolation, a dedicated interface and an S3-compatible API endpoint to manage storage spaces, access rights, projects, configurations, metrics, reports and billing.

The system is intended for uses including immutable backup, disaster recovery, long-term archiving and large-scale management of unstructured data.

GigaCloud said it will target mid-sized and enterprise customers across the public sector, with a focus on government and defence, as well as financial services, media, retail and IT.

Nazariy Kurochko, chief executive of GigaCloud, said: “Cloud infrastructure in our region can’t be built around assumptions borrowed from calmer markets.

“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.

“For us, it is also a step toward strengthening a European cloud ecosystem where resilience, sovereignty, and a technology-agnostic approach are built into the foundation.”
