Telefónica Brazil has completed the migration of its core IT production environment from legacy virtualization to Red Hat OpenShift, according to an announcement made by Red Hat at MWC Barcelona. The move is intended to create a more agile and scalable foundation for Telefónica Brazil’s business-critical workloads.
The telecommunications company, which serves 116 million customers, reported significant improvements after the migration. These include reducing the time required to scale IT resources from 24 hours to just 10 minutes—a reduction of 99%. Storage consumption was also cut by 95%.
Guilherme Marinasco, Senior Management and Platform & Product Engineering at Telefónica Brazil (Vivo), said: “Our goal is to provide the most reliable and innovative digital services to our 116 million customers. Modernizing our core infrastructure to an open hybrid cloud with Red Hat’s common cloud-native platform allows us to be more responsive to customer needs, reduces our environmental footprint through better resource utilization, and provides the flexibility that we need to lead in the development of next-generation AI and cloud-native workloads.”
The new containerized architecture on bare metal helped Telefónica Brazil decrease IT CPU consumption by 55% and memory usage by 65%. Customer interactions have improved as well, with response times for data collection reduced by 42% and billing inquiries by 61%. Patch update times dropped from four hours to just twenty minutes—a decrease of 91%.
According to Red Hat, this transition enables Telefónica Brazil’s environment for future AI-native operations. By removing limitations imposed by legacy virtualization systems, the company is now positioned for further automation and optimization using specialized AI models.
Gino Grano, global vice president for Americas Communication Service Provider Segment at Red Hat, stated: “Telefónica Brazil is a prime example of a forward-thinking ‘techco’ that recognizes legacy virtualization as a potential barrier to the speed and cost-efficiency required in its transformation. By migrating business-critical workloads to Red Hat OpenShift, Telefónica Brazil has not only realized massive infrastructure savings but has also built a sovereign- and AI-ready foundation that can adapt as quickly as the market demands.”
With this shift, Telefónica Brazil has unified management of modern cloud-native applications alongside remaining virtual machine workloads on a single platform.
