Enterprise IT Roundtable: Navigating the NaaS Journey
In the face of changing traffic patterns thanks to AI workloads, increasing network complexity, ever-present security threats, the need for business agility, a shortage of skilled personnel and CAPEX budget constraints, Network-as-a-Service (NaaS) is emerging as an attractive alternative. Join your peers for an open discussion of the challenges and opportunities for plotting the course for your company’s NaaS journey. What are the prime use cases spanning traditional wide area and local area networks as well as emerging multicloud networking architectures? What are the key business, operational and technical challenges? Learn what others think about NaaS and why this new model has the potential to deliver more business value than traditional managed service offerings.
This roundtable session is exclusive to IT professionals and subject to Chatham House rules.
