5G EdgeCloud - part 2


Cloudification” of telecommunications infrastructures and MEC/Edge-Cloud are leveraging on the exploitation of the (almost) full “virtualization” of both resources (e.g., processing, storage and networking) and network/service functions (e.g., Virtual Network Functions) up to the edge (i.e., access, distribution segments), or even beyond it up to the terminals or smart things (i.e., Fog Computing). 

MEC/Edge-Cloud is just a piece of the overall puzzle, as the border with Cloud Computing is disappearing soon !

This innovation trend in offering the opportunity of extending the business role of telecommunication Operators to play the role not only of Service Providers (for SaaS) but also the roles of both IaaS Infrastructure-as-a-Service (IaaS) Provider and Platform-as-a-Service (PaaS) Provider, in global markets.

This creates the conditions for boosting new open ecosystems, easing life to Applications and Service Developers.

In order to materialize this vision, there should be a clear definition of what are the services offered by the 5G IaaS and PaaS and the related open/standard APIs to access them.

For example, Infrastructure as a Service (IaaS) layer offers:
  • Raw virtual resources for connectivity, processing, storage;
  • Virtual Network Functions and other Network Services (e.g., middleboxes such as bridges, routers, load balancers, firewalls, video optimizers, etc).

Platform as a Service (PaaS) layer provides a controlled access - through standard interfaces API - to underneath IaaS. Moreover, PaaS include, for example:
  • Operating Systems services, services and apps development instruments and tools, database management capabilities, business analysis, A.I. tools, etc

The following picture is summarizing a number of possible business models, capable of re-defining the equilibria in the overall Industry.
