Digital Transformation is fast becoming a key strategic objective for many Communications Service Providers (CSPs). Moving BSS to the cloud is an important aspect of this transformation. However, many CSPs do not have a strategic roadmap to migrate their BSS to the cloud and very often the key drivers for cloud adoption are purely commercial objectives. While CSPs understand that moving to the cloud makes perfect business sense, the reason for this passive approach stems from privacy and security concerns, internal resistance to change and a perceived immaturity of cloud technologies, among other concerns. As more CSPs offer cloud services to their customers and see demonstrable benefits, many expect the cloud BSS adoption levels (currently <10%) to dramatically increase by 2020.
