Inspired by Deepak Bansal’s presentation at Future:NET 2018, Roger Lund looks at Unified Software-Defined Networking for Microservices. He considers if this is something that can be achieved, or just a pleasant fantasy.

VMware’s Virtual Cloud Network Fulfills the SDN Promise
VMware recognizes the challenge in bridging software-defined domains into a cohesive unit and has started to build out a portfolio of software-defined products that work seamlessly together. Jordan Martin takes a look at why their Virtual Cloud Network fulfills the original promise of software-defined networking.
All Your Networking Are Belong to NFV | The On-Premise IT Roundtable

On this episode, we’re discussing Network Functions Virtualization, aka NFV. The roundtable discusses what exactly NFV is, how it differs from SDN, and if it’s going to eat all specialized networking hardware. The discussion then turns into how changes in network design principles make NFV even more viable in the enterprise.
The Logic Of Tables with Broadcom SDKLT
Broadcom announced their new SDKLT, a logical table-based API for programming Tomahawk switches. But why is this new idea so important? Tom Hollingsworth looks at the impact of both the new data structures and open source release and why it matters to network programmers.

Intent-based networking is the new hotness, but what does it actually mean? In this episode, the panel discusses how it differs from older SDN ideas. IBN integrates an abstraction layer and orchestration into a system that identifies a single source of truth that isn’t the network itself.
What Is Automation? The On-Premise IT Roundtable

On this episode, we’ll be talking about a hot topic in the networking space, automation. The panel discusses why organizations see automation as prohibitively complex, what exactly they mean by automation, and why it isn’t coming for their jobs.
Network Longevity – Think Car, Not Smartphone
With all the expectations and hype that surround software-defined networkings, it’s easy to get a little jaded. But that misses the massive impact it’s had for enterprise networks. In this piece, Tom Hollingsworth rightly points out that this programmability is no longer a new feature that network engineers are excited about. Instead, it’s become a staple of the modern data center, one that increasingly organizations depend on.
Moving beyond the CLI with Aruba 8400 (Enabling SDN for NetOps)
When I first saw the Aruba 8400 I was awestruck, surprised, actually legitimately excited! I know, I know it’s just a bunch of ports inside of a chassis, but that’s not all it was though. The 8400 brought something to the party which has been forlorn and forgotten in the systemic world of Network Engineering and Administration, and that is they realized the end-users of this product WERE Network Engineers and Administrators. But wait, what do I mean by that?
Intel NFV, an SD-WAN Cook-Off, and a Missing Control Plane in Gestalt Networking News 17.6
On this iteration of the Gestalt IT Networking News:
– Discussing Intel and NFV on our new podcast, the On-Premise IT Roundtable
– TELoIP tries to shake up the same old SD-WAN recipe
– An in-depth look at TCP terminator
Plus looks a VMware NSX, the future of SDN, and trying to find out who moved Jordan Martin’s Control Plane!
Who Moved My Control Plane
Jordan Martin has a problem. The idea of moving the control plane from a device to a central controller sounds like it makes a lot of sense in SDN. I mean, it’s called a control plane, why not move it to a controller? Despite the phonic similarity, this isn’t actually what happens.
