The development paths of the telecom and IT industries are merging. In fact, nearly all industries, as they transform to digital processes, are moving toward collaborative business models, with telecom providing the key ingredient of mobility.

The latest Ericsson Technology Review highlights one example of the collaborative shift and how it enables technologies developed for one sector to be used by others. Platform as a service (PaaS) is a cloud service model that simplifies the process of building, running, and managing applications. As the platform provides the fundamental functionality, a PaaS application can be designed to meet the needs of the business solution. This approach results in leaner, less complex, and more flexible applications, which in turn brings scalability.

But, before PaaS becomes telco-grade with five-nines availability, and with the capability to meet low latency requirements, a number of gaps need to be closed. Once these gaps have been closed other sectors that have stringent real-time and security requirements, such as banking and medical, will also be able to benefit from the PaaS approach.

Increased fiber penetration, the separation of hardware and software, changing traffic patterns, the virtualization of network functions, as well as DC fabrics like merchant silicon leaf-and-spine switches, are just some of the factors affecting the role of the central offices (COs) and the mobile switch offices (MSOs) of modern networks.

Digitalization has been an ongoing process in telephony since pulse code modulation, but what I see right now is a second wave of consolidation enabled by improved flexibility. Network functions that at one time were implemented by hardware and placed in strategic locations have been replaced by software that can run on generic hardware with instances that can placed where they are needed most – close to the user, or in a cloud DC.

The latest Ericsson Technology Review provides an insight into the technology enablers and the key architectural considerations that will transform COs and MSOs into sustainable highly-automated mini data centers – the CO of the ICT era.
