Core network Software as a Service | Nokia.com (2025)

Core SaaS can substantially enhance an existing installation by offering much simpler cost control, faster time to market and greater support for new service creation.

By transferring more of the core’s ownership and operation to Nokia we take on more responsibilities than it would in a traditional on-premise or off-premise deployment. This reduces your workload to run the physical data center and infrastructure, freeing you to focus on your business. You could also gain by not having to take on associated costs, such as electricity, cooling, security and operations.
