  This paper presents two new challenges for the Telco ecosystem transformation
in the era of cloud-native microservice-based architectures. (1)
Development-for-Operations (Dev-for-Operations) impacts not only the overall
workflow for deploying a Platform as a Service (PaaS) in an open foundry
environment, but also the Telco business as well as operational models to
achieve an economy of scope and an economy of scale. (2) For that purpose, we
construct an integrative platform business model in the form of a Multi-Sided
Platform (MSP) for building Telco PaaSes. The proposed MSP based architecture
enables a multi-organizational ecosystem with increased automation
possibilities for Telco-grade service creation and operation. The paper
describes how the Dev-for-Operations and MSP lift constraints and offers an
effective way for next-generation PaaS building, while mutually reinforcing
each other in the Next Generation Platform as a Service (NGPaaS) framework.
