The notion of composable infrastructure or infrastructure abstraction is one of my favorites. I think it’s probably the most important piece of our overall virtualization puzzle, in fact, but it’s also something that could present serious problems. That’s particularly true given how fuzzy the concept is to most users. At the end of last year,…
A Cisco executive cites five network technologies as critical for enterprises in 2019, according to a Cisco blog and a Network World article. In fact, these five will be game-changers according to Cisco’s VP of engineering, so “2019 is going to be a transformative year in enterprise networking.” What are these technologies, and is Cisco…
Virtual networking or Network-as-a-service (NaaS) makes connectivity easier, but it complicates automation of lifecycle processes. The problem is that when “services” are created on top of connectivity rather than through the same devices that provide connectivity, you lose some insight into service behavior. You also lose pretty much all of the traditional ways of doing…
Earlier this week I blogged about virtualization and infrastructure abstraction. I left the modeling aspect of that to the end because of my intentional focus on the abstraction side. Now I’d like to look at the same problem of virtualization from the modeling side, so see where we end up and whether conclusions from that…
We all know by now that both Apple and Samsung, giants in the smartphone space, have issued sales warnings. What we don’t all know, and what in fact none of us really knows, is what this means to networking both at the service and the infrastructure level. Smartphones are arguably the most significant single devices…
I blogged yesterday that virtualization was the key to operations automation, which in turn is the key to the future, the thing we needed to look for in 2019. The central vision in cloud and virtualization is that of a resource pool. With resource pools, the trick is to make them as inclusive in terms…
How different is January first from December thirty-first? Not much in most ways, and of course it’s after January first now, but it’s still true that businesses think in terms of quarters and years, and so it’s fair to look ahead at our annual transition point to see what important things are coming down the…
I want to wish all you who have read my blog, occasionally or faithfully, for their efforts, and wish you all a Happy Holiday season and an exciting and prosperous New Year! Email and RSS:
Just when you express hope that the network industry can shed the past, somebody demonstrates it won’t be easy. An interview in Light Reading with Amdocs CTO Anthony Goonetilleke proposes that one of the unsung benefits of 5G is that it will enable operators to charge for services rather than for data. Is this really…
The widely reported VMware acquisition of Heptio raises a lot of very interesting points about cloud computing, application development, and the newly competitive world of platform software. It even has implications for the network operators and vendors in that space. Finally, the scope of change the announcement is part of shows that the ecosystemic vision…
