The Past, Present, and Future of the Telecom Cloud

This white paper discusses the evolution of the telecom cloud, detailing its past, present, and future. It begins by outlining the historical context of telecom networks, highlighting the transition from mechanical switching to digital telecom switching in the 1980s. The paper emphasizes the significance of network functions virtualization (NFV) and cloud-native network functions (CNFs) in modernizing telecom operations. It explains how NFV revolutionized network functions by enabling them to run on virtual machines, leading to cost reductions and increased flexibility. The current state of the telecom cloud is characterized by a hybrid environment where VNFs and CNFs coexist, supported by various deployment models across core data centers and edge sites. Looking ahead, the paper presents a vision for the future telecom cloud, which will be AI-ready and automated, requiring a consistent operational model across all environments. It also discusses the importance of data sovereignty and the role of advanced technologies in shaping telecom operations moving forward.
