Telco cloud made big promises for the transformation of telecoms. It is a fundamental enabler for 5G and the exciting opportunities ahead. Why hasn’t it delivered yet – and what needs to change?
The early high hopes for SDN and NFV have given way to the realization that the road to cloud-telco ‘heaven’ is strewn with ‘infernal’ rocks and pitfalls.

What are the challenges to making it happen, and what do telcos and vendors need to do to succeed?
