O2 Telefónica will be able to bring Google Cloud’s infrastructure and services closer to where data is being generated
O2 Telefónica is using the 5G cloud core network to deploy and test real-world customer applications and networking solutions for mobile broadband, network slicing, real-time applications and private 5G networks in a testing environment, optimize performance and prepare the network for live operations. In order to comply with strict data protection requirements, no real customer data of O2 Telefónica is used. For operations, O2 Telefónica is leveraging Google Cloud's infrastructure and deploying Google Distributed Cloud Edge in its data center. The functions of the 5G core network, provided by the dual-mode 5G Core from the European network equipment supplier Ericsson, are based entirely on software. Through Google Distributed Cloud Edge, O2 Telefónica will be able to bring Google Cloud’s infrastructure and services closer to where data is being generated and consumed within its 5G core network.

O2 Telefónica is building industrial 5G networks together with Ericsson
O2 Telefónica, Google Cloud and Ericsson are already successfully collaborating on modern 5G networking solutions: O2 Telefónica is building industrial 5G networks together with Ericsson. In addition, the telecommunications provider uses Google Cloud for part of its services. Together with the focus on technological innovation, security of communication content and customer data has always been a top priority for O2 Telefónica. Among other things, the company uses a comprehensive Cloud Security Framework that meets the highest data protection requirements and leverages the highest security mechanisms to protect European data. For example, all cloud data centers are operated in Germany and are therefore subject to the European Data Protection Regulation (EU-DSGVO).
