What is the actual business case for moving our core network functions to the cloud?

The transition from hardware-centric to software-defined architectures allows telcos to shift from CapEx-heavy models to OpEx-driven service-based architectures. This move enables massive efficiency gains, such as the 80% reduction in product development time achieved by Vodafone through hyperscale integration.

Can we trust hyperscalers with our carrier-grade uptime requirements?

Full public cloud outsourcing is currently deemed too risky for incumbents due to the 99.999% uptime requirement of carrier-grade networks. A hybridisation model has emerged as the industry standard to balance cloud-native innovation with the operational stability of on-premise infrastructure.

How much faster can we actually innovate using these platforms?

Leveraging hyperscaler R&D pipelines, specifically in AI and machine learning, drastically compresses development cycles. Vodafone reduced its AI development time by 90%, moving from a 20-week cycle to just 2 weeks by utilizing Google Cloud’s platform.

What are the biggest risks to our long-term independence?

Technological lock-in and the erosion of service freedom pose existential risks that could reduce telcos to 'dumb pipes' for cloud providers. Data sovereignty remains the primary technical hurdle, forcing the adoption of sovereign cloud solutions to maintain regulatory compliance.

Abstract

The convergence of the software-defined core network architecture with the dominance of hyperscale cloud providers in automation and artificial intelligence (AI) has forced telecommunications operators to a strategic crossroads.

Key Takeaways

Telcos are shifting from hardware-centric cores to software-defined, service-based architectures (SBA) to enable cloud-native network functions.
The primary executive rationale for cloudification includes shifting from CapEx to OpEx and accessing hyperscaler AI/ML R&D pipelines.
Full public cloud outsourcing is deemed too risky for incumbents; a sophisticated hybridisation model is emerging as the industry standard.
