A number of well-known drivers are paving the way towards an end-to-end X-as-a-Service world, a truly Digital Transformation of Society and Economy:
- pervasive diffusion of ultra-broadband (fixed and mobile);
- increase of performance of H/W at lowering costs;
- growing availability of Open Source S/W;
- availability of “actionable” Big Data;
- advances on Artificial Intelligence;
- more and more powerful terminals and smart things.
We realize that Softwarization of Telecommunications – and several other Industries - will be the natural next step of this Digital Transformation. Automating Operations will be the key factor of success, in a growing complexity and heterogeneity. On the other hand, we are witnessing a rather high level of fragmentation, in international forum, bodies, projects and initiatives developing systems, platforms for management, control and orchestration…even more when looking at 5G infrastructures.
Moreover, it is not predictable today which of said platform(s) will be widely accepted and deployed, and how they will evolve. Impossible to predict today which one will be “the winner takes all”. My take is that to cope with this, there is a need of developing an “infrastructure-agnostic orchestration space” capable of decoupling from currently available (and future) control and orchestrations platform (e.g., ONOS, ODL, OpenStack, MANO, etc) … but at the same time “hooking” all of them (for end-to-end services) by using a standard set of abstractions.
Scalability, security, and accounting will represent some of the major challenges towards this fully automated, agile, multi-domain, end-to-end X-as-a-Service world.
