Apstra: The Intent-Driven Cure for Network Blindness

Apstra, Incorporated isn’t focused on new features, more advanced silicon, or some new widget. Instead, they’re offering a different way to look at networking. Apstra offers an early form of intent-driven networking that abstracts network programmability and allows network engineers to configure intent rather than device features. We expect the network to behave in a specific way, so we configure our intent accordingly. I was very excited to meet the Apstra team at Networking Field Day 13, and they didn’t disappoint.

SD-WAN with VeloCloud at Networking Field Day 13

It looks like we’re going to have some SD-WAN goodness next week at Networking Field Day 13. I love the technology itself because of the real-world use case and practical benefits a good SD-WAN solution can offer.  Many of the SDN-labeled offerings out there are still a little immature, but adding intelligence to the WAN edge is something that is already being adopted wholeheartedly in even small enterprises.

Intent-Driven Networking with Apstra at Networking Field Day 13

In a couple weeks I’ll be headed to sunny San Jose for Networking Field Day 13. If you’re not familiar with Networking Field Day and other Field Day events, check out their website, YouTube channel, Twitter feed, and LinkedIn page. Tech Field Day does a great job bringing technology influencers, bloggers, and craft beer enthusiasts together with some of the biggest and newest names in the tech industry.

I’m particularly interested in Apstra’s presentation on Thursday afternoon. I recently wrote an article about intent-driven networking, something of particular interest to me, so I’m really interested to hear what they have to say about their platform, the Apstra Operating System, or AOS.

Network Automation: Another Tool in the Toolbox

Over the last few weeks I’ve noticed a few tweets and blog posts regarding the immaturity of network automation methods and the danger in utilizing those methods in production networks. Though I agree that processes always have room to mature and that wiggling wires in a production environment always poses some risk, I believe this new emerging narrative in social media makes several assumptions that aren’t necessarily true.

Fate Sharing in the Network Core

Untitled

Network engineers like redundancy. It’s not that we just want double of everything – we want the networks we design and manage to be super fast, super smart, and super resilient. In the LAN and in the data center we’ve been logically joining network switches using technologies such as Cisco StackWise, the Virtual Switching System and Virtual Port Channels with fabric extenders in order to consolidate control and data plane activities and provide greater fault tolerance, easier management and multichassis etherchannel for path redundancy. These are great benefits, but they can be reaped only by proper design. Otherwise, an engineer may introduce more risk into the network rather than make it more resilient.

I Still Go To School Every Day, But Now I Call it Professional Development

Few fields require the continual professional development that IT does, but few fields offer the incredible rewards that a commitment to developing the skills of our trade can provide. Many factors come together to shape if, why, and how we advance in our field, and though I can speak only of my own experience, I believe the lessons I’ve learned from my journey so far may be of some value to others also on a similar path.

Why Buy One When You Can Buy Two For Twice the Price

I get pretty excited when new network gear shows up at the loading dock. I get psyched when I get to configure an interesting technology that I rarely get to use. But considering our responsibility to our customer or employer, sometimes we need to put that aside in favor of the simpler (or cheaper) but more appropriate solution. Let me give you one example.
