3.4.1. Transition to the new service delivery model

The implementation of this new service delivery model represents a significant evolution for a typical area control centre (ACC) (1), which today relies primarily on on-site infrastructure, consisting of servers with dedicated hardware and on-premises software deployments. The infrastructure of tomorrow’s ACC will be far more versatile, incorporating both on-premises components and leveraging various cloud types (i.e. private, public and hybrid). This new architecture will support multiple deployment models, including infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS), and cloud-based business services (backend as a service - BaaS). This evolution will enable ACCs to scale their service delivery more efficiently, integrate new technologies seamlessly, and benefit from faster innovation. The new model will also increase resilience, as it will enable the operation of services from different locations, and dynamically switch locations in case of local system disruptions (as illustrated in Figure 4).
