Cloud anyways now a part of most of the businesses and telecom is not an exception. What is more important with virtualization is the customer-centric approach, one has to give superior experience to customers which help to maximise revenue. IoT and Dynamic Billing are also there which cannot be neglected when talking about future. Most of the telecom operators and software providers like Vodafone, Airtel, Cerillion, Skyline have already started designing their strategy around them to get the competitive edge. Would be interesting to see how they adopt these evolving technologies and increase their revenues.
