Ukrtelecom switched two data centers to SDN architecture
Ukrtelecom has completed the migration stage to a new modern network architecture Software-defined Networking (SDN) based on Cisco ACI. The works have been carried out in two data centers of the telecommunications operator in Kyiv and Dnipro. IT-Integrator was the implementation partner.
The implementation of the project began 3 years ago, when Ukrtelecom faced the need to modernize the network infrastructure of data centers. The main prerequisite was the lack of support by manufacturers of the old equipment park and the associated possible risks for the company’s business. When analyzing proposals, the customer was looking for a promising and complete solution available in Ukraine. As a result, Cisco ACI architecture was chosen for the project.
One of the priority tasks for Ukrtelecom was to understand the principles of the chosen solution and to analyze its possibilities for the further development of the company. Among the advantages of the solution: ample opportunities for segmentation of services and creation of service chains, a single point of management of the converged network and automation of settings. These and other technological advantages opened up opportunities for the further development of digital services and business of Ukrtelecom.
After the mandatory full design cycle, the next step was the implementation of the solution and the migration of all network services of the data centers (the Network Centric stage). Ukrtelecom chose Cisco Firepower firewalls to transfer all corporate network security policies during the project. This task turned out to be complicated, since during its existence the network infrastructure has accumulated a large number of specific settings that needed to be competently transferred to the new infrastructure. In fact, the process included the transfer of a huge distributed, heterogeneous and multi-vendor network of data centers to a modern software-controlled factory with a different internal logic of work.
Oleksandr Rudenko, Head of IT-Integrator Implementation Department: “Implementation of Cisco ACI is not just a story about a solution, it is a long-term choice and implementation of Ukrtelecom’s development strategy in the direction of data center network infrastructure – a strategy that is designed to radically change approaches to the functioning of the company’s digital services”.
Goncharuk Kyryll, CIO of Ukrtelecom: “The transition to SDN architecture is a truly significant event, because the rapid change in traffic volumes and changes in its structure requires not only to modernize networks and switch to fiber-optic technologies, but also to revise approaches to software transformations, which allow us to maintain a leading position in the digital services market and open up new directions, to adjust our IT landscape to new market challenges with flexibly and swiftness. Thanks to the partners with whom we have worked side by side over the past two years to implement the Cisco ACI architecture. Thanks to the competencies of IT-Integrator and Cisco we confidently moved towards our goals and continue our path of transformation.”
Sergiy Martynchuk, Head of Cisco Business in Ukraine: “Cisco ACI is the industry’s best SDN solution that improves application flexibility and data center automation efficiency. We are very pleased that thanks to our technologies, Ukrtelecom will be able to quickly and safely develop new digital services”.
The next stage after the full migration to the new network architecture of the two main data centers is the Application Centric phase – a direct transformation of the network infrastructure and the policies. This transformation will be aimed at describing the network interaction with respect to those services that are located in the data centers. The chosen service-centric approach will maximize the protection of Ukrtelecom’s services at the basic network level, while simultaneously reducing the risks of horizontal spread of network attacks thanks to the White-list or Zero Trust.
