Naftogaz Group is the largest group of fuel and energy companies in Ukraine. It is state-owned and employs over 50 thousand workers. The Naftogaz Group includes Naftogaz of Ukraine, as well as 7 joint stock companies, 9 subsidiaries, 7 representative offices and affiliates. NJSC Naftogaz of Ukraine is the largest national oil and gas company of Ukraine.


The IT infrastructure of NJSC Naftogaz was hosted on its own physical servers, which were rather outdated and did not meet the needs of modern automated systems. Technical specialists could no longer modernize them.

Then the management started considering the use of cloud technologies. The same was required by the updated IT strategy of the company, based on the use of private clouds for hosting critical IT services. In addition, Naftogaz Group engaged cloud technologies back in 2018, so migration to the cloud would optimize infrastructure support costs.


In January 2021, the company issued a tender, and as a result of which the GigaCloud cloud operator offered the best conditions among all participants. NJSC Naftogaz moved physical and virtual servers to the private cloud.

A private cloud is a physically isolated virtual infrastructure that is provided to the customer for exclusive use and has the highest level of availability and security, which is very important for companies with critical infrastructure. The GigaCloud private cloud met the following customer’s requirements:

  • the data center to host cloud infrastructure is located in Kyiv, close to the company;
  • information security management in the cloud meets the requirements of the international ISO 27001:2013 standard;
  • the cloud infrastructure is built using licensed software.

GigaCloud technical specialists helped migrate the NJSC Naftogaz IT services to the cloud, providing high-quality and fast consultations and advice.


After the company deployed its services in the GigaCloud private cloud, it received a number of opportunities.

“Cloud services, in contrast to a traditional IT system which is built on own equipment, give business a few more advantages,” says Oleksandr BaranchukHead of IT department at Naftogaz of Ukraine. “This is an opportunity to increase computing power for your systems and flexibility of its distribution between IT infrastructure components, reduce risks associated with the outdated server and communication equipment failures, and raise the level of IT services continuity.”
