The Whole Picture

Greg Ferro recently presented a challenge to the industry, 30 blogs in 30 days, and I think I’m going to try and tackle that. I’ve always struggled with posting to my blog and curating content to give back to the community – especially the rate as which I consume what’s out there. I have a responsibility to give back more. So, without further ado.

As I’ve been working through some projects at Plexxi, I’m starting to broaden my skill set with respect to computing as a whole, and not just the networking the machines together. And I made a realization, very quickly. I don’t know nearly as much as I’d hoped. All of the time I spent proving it _wasn’t_ the network didn’t help much in learning exactly how applications are architected, why those applications communicate the way they do and how I could actually provide some feedback to the developers and administrators that could help them.

Moving from consuming abstractions and using them to configure single devices in a network, to building workflows and abstractions that enable those workflows, with respect to an entire system has been absolutely eye opening. The networking field seems so small when looking at it from the big picture. Yes, there are considerations to be made with respect to what protocols to deploy within that network and how to architect it, what failure scenarios exist, separation of failure domains, etc, but all of those times where the defense went up when an application administrator, or developer complained that the network was the problem all seem so shameful.

What I should’ve been doing is shutting up, sucking up my pride(network engineers are a prideful bunch), and sitting down with the application administrators and developers and helping them to understand the network while they helped me to understand their systems. Sound familiar?…(DevOps for those who didn’t make the connection)

As I work through some of these integrations I feel like I’m in my first few years of my career again. I’m a stumbling, bumbling toddler trying to sort and make sense of all of these new languages and technologies and how we can architect them, and ensure they’re consumable and agile enough to be deployed through many different infrastructures and iterations. Its almost liberating. Terrifying, because I am now dealing with everything BUT what the last 8 years of my career have been, but liberating.

Talking up and back down the stack again, and beginning to understand what the bits look like in flight above L4 is an awesome experience. Reading white papers, and research papers and understanding things like eventual consistency and tying that back to something like OSPF and realizing that John Moy was a genius in his own right. Creating a distributed application, albeit primitive compared to what we have today, that has lasted decades and scaled very, very well.

So, I encourage everyone in the networking industry. Talk to the developers are your organizations. Talk to the application administrators, understand what their software looks like. Understand _why_ it was built that way and how it could possibly be refactored for better performance. Who knows, you might even find out that you actually like working on systems outside of the network and you’ll be able to make different employment decisions in the future due to the knowledge you gain through these interactions.

So that’s my advice. Drop the attitude that every network engineer seems to have, sit down and work together with everyone else. Be a bit of a hippy and embrace diversity and difference perspectives. You won’t be sorry.
