Continuing with my model-and-event-driven service automation theme, some of you wondered whether I could dig a little deeper into how state/event processes were hosted, and also why ExperiaSphere mandated the separation of “orchestration” into a service and resource layer. This also gets into how federation of services across provider boundaries (or across administratively separate parts…
When I did my blog yesterday on the problems with the ETSI ZTA software architecture, I had a number of emails asking how you could do lifecycle management using state/event principles. They showed me that one problem we have in coming to a good consensus on ZTA software is the general lack of understanding on…
In past blogs I’ve talked about abstract threats to the ETSI zero-touch automation (ZTA) project, but referencing one of the open documents, I want to talk here about the real threats that are now visible in the early documentation. ETSI’s reference architecture for ZTA balances the new and old of standards, but I think one…
Virtualization is all about abstraction, and in most cases that means abstracting resources and building resource pools. The ideal vision of “the cloud”, whether it’s a private cloud, a public cloud provider or carrier cloud, is one of a vast pool of resources that can be tapped as needed to provide the optimum in economy…
There was a thoughtful piece on NFV in Light Reading last week, and it raises a lot of points that are becoming important as carrier cloud opportunity awareness grows in the industry. The big point the article makes is one of unrealistic expectations, and surely in our hype-driven tech world, that’s a problem. I do…
VMware has been in the news this week, both for its plans to make its Virtual Cloud Network “real” and for the acquisition of the Dell EMC Service Assurance Suite’s technology group. The two moves, as I’ve noted in an earlier blog, seem directed primarily at the network operator, managed service provider, and cloud provider…
Maybe you believe in edge computing, or in IoT or AI, or maybe carrier cloud, or all of the above. The main thing is you believe the future requirements for applications and hosting will be different, and so the data centers and servers of the future will be different. The obvious question is what these…
I blogged quite a while ago about “intent-washing”, the tendency to use the terms of intent models and modeling where that’s not really the story being told. Like all “washing”, intent-washing is driven by a desire to ride a positive news wave even when you’re not really doing exactly what the term means. Cisco is…
Cisco always signals important market moves, sometimes with tangible changes and sometimes just by erecting an attractive billboard aimed at the media. The one they announced last week, the integration of the Viptela SD-WAN software with Cisco routers, is surely in the first category. Still, does this signal a problem for vendors in the space,…
As a former software engineer, architect, and head of some high-tech programming groups, I love APIs. I also have to admit that APIs are getting to be a lot more complicated than they used to be, and things like edge computing, event processing, and microservices are promising to make them even more complex over time. …
