“If we march into that village and we start trying to persecute people for using poison, something that's very illegal, nobody's going to talk to us. We're not going to find out where the poison came from. We're not going to be able to shut anything down. We should take the approach that people are using poison because they're desperate, because they see no other alternative.” – Andrew Stein Andrew Stein is a wildlife ecologist who spent the past 25 years studying human carnivore conflict from African wild dogs and lions in Kenya and Botswana to leopards and hyenas in Namibia. His work has long focused on finding ways for people and predators to coexist. He is the founder of CLAWS , an organization based in Botswana that's working at the intersection of cutting-edge wildlife research and community driven conservation. Since its start in 2014 and official launch as an NGO in 2020, CLAWS has been pioneering science-based, tech-forward strategies to reduce conflict between people and carnivores. By collaborating closely with local communities, especially traditional cattle herders, CLAWS supports both species conservation and rural livelihoods—making coexistence not just possible, but sustainable.…

M4A•Thuis aflevering

I saw a comment on a network automation forum, and while the poster made a lot of great points, there was one point I disagreed with: That DevOps practices are a necessary component on network automation. While I think there are some aspects that are important, going full CI/CD pipeline isn't necessary. Here I give my quick thoughts on this subject.

Too Many New Things At Once 5:02

28 dagen geleden5:02

5:02

In this episode I talk about the pitfall of throwing too many new things at once to someone who's just learning network automation. Keeping it simple and using a layered approach is what I've found to be the best way to introduce network automation to new people.

Test Driven Deployment 11:02

10 weeks geleden11:02

11:02

In the software development world, they have a concept called "test driven development", whereby code is tested (unit tests, integration tests) before committing to the main branch and before deployment. We can take that concept and use it in the networking world, and to some extent we are, but there's more to go. The tools haven't quite caught up with the concepts, however, and I discuss this on this episode.…

CI/CD and Network Automation 20:53

17 weeks geleden20:53

20:53

In this episode, I talk about what CI/CD is for networking automation as well as the general idea for what is in the developer world. And more importantly, I talk about how most organizations probably don't need full CI/CD, they can get a lot of benefits from network automation by adopting three practices (that are part of CI/CD, but alone aren't CI/CD): Configuration generation Automated config deployment Automated post-deployment testing…

There's marketing terms, and then there's words that accurately describe a new way of doing things. Cloud computing was one of these terms, and now "Network as Code", "Network Automation", or the older "Software Defined Networking", while they can be used a marketing fluff, they do represent a different way of doing things.…

REST API or RPC? 6:34

In this episode I talk about the two main categories of APIs you're likely to run into as a network administrator: REST APIs and RPCs (XML-RPC, JSON-RPC, gRPC, etc.) and why a device might have one or another.

Network Controller Concepts and Evolution 6:04

In this episode, I share my thoughts on what constitutes a network controller. Back in the early 2010s, it was thought to be the way devices had their forwarding tables configured. Now it's how a devices configuration state is configured.

The Term "CLI" and Network Automation 4:57

4:57

A recent discussion had me thinking about the two common uses for the term "CLI" (Command Line Interface, of coures) with regards to network automation: One is the configuration method (as opposed to API or GUI), and the other is the configuration state (CLI syntax, such as running-config on Cisco/Arista).…

Raw Python versus Frameworks/Platforms 2:51

2 years geleden2:51

2:51

In this short episode, I talk about making your own platform versus using an existing platform/framework. An example would be writing your own Python automation platform, versus using something like Nornir (which is a platform plus some Python) or Ansible. I talk about why it's usually a good idea to use an existing platform versus making your own.…

Incremental Configuration Change versus Total Configuration Replacement 7:34

2 years geleden7:34

7:34

One of the things we think about as network automators is the concept of incremental change versus total configuration replacement. Traditionally all our changes have been incremental. From the day a switch/router comes online, it's little change after little change. In this episode I talk about how this changes from incremental changes to total configuration replacement when working with most types of automation.…

APIs: Open or Na? 7:01

2 years geleden7:01

7:01

In this episode I talk quickly about whether APIs should be standardized. Pretty much all APIs are open in that the vendors allow anyone to access them and the specifications on how to interact with them are public. But using NX-API from Cisco and eAPI from Arista means using two different sets of commands to do that same thing. Projects like OpenConfig/gNMI are meant to provide a single way to configure parameters no matter the devices through a single data model. While this is useful, in the data center it's not so much a problem we tend to have. Working with one API is OK, since data center networks are typically built using only one vendor.…

When I teach an automation course, I'll typically show a video: https://www.youtube.com/watch?v=HluANRwPyNo (a bit of foul language in it... but very realistic use of it) In networking, everyone Google's everything. Got an error message? Google Search. Can't remember how to do something? Google Search. The same is true in network automation. Also, this comic from XKCD: https://xkcd.com/979/…

Whither VIM? 3:22

3 years geleden3:22

3:22

Recent discussions on Twitter and in a few classes brought up the venerable VI editor (or the more common upgrade to VI, VIM). It was once a must-learn tool for Unix/Linux/BSD administrators. It was used for editing configuration files, data entry, and even coding. These days it's not quite the must-have it used to be. In fact, most people working in the industry can get by with the less capable, but far easier to learn, nano editor.…

On Supplemental and Total Automation 7:39

3 years geleden7:39

7:39

In this episode, I talk briefly about two different depths of automation: Supplemental and Total. With supplemental automation, automation is used only on part of a config (SSH keys, DNS, NTP, etc.) while the rest of the device is configured in the traditional (i.e. manual) way. With complete automation, no more manual configuration is done and the entire configuration is done through some sort of automated means.…

On twitter (my handle is @tbourke) I asked for people to submit any questions about network automation that they might have. I got one response pretty quickly from @el_dude_abides, and here were their questions: Will SNMP ever go away? YANG or NETCONF? GUI or CLI best? Will application & server peoples ever understand how their stuff works? (i.e. ports, transport, source/destination) All great questions, and I want to thank the Network Dude for asking them. I answer them in this episode. Enjoy!…

Pep Talk for Network Administrators Learning Automation 17:42

3 years geleden17:42

17:42

In this episode I give you a "pep talk", a bit of encouragement for those that are experiencing some fear and perhaps even some loathing when it comes to learning network automation. Generally, I see three main reasons why students I encounter and network professional are hesitant to learn network automation skills and tools: They think they don't have the talent for it (the midichlorian problem) They think they'll automate themselves out of a job They think they're too old to learn I go through each one and talk about them. I hope it helps address any hesitation you might have.…

This podcast is a series of single person, just me (Tony Bourke) talking about the network automation journey. While there's a lot of resources out there to help people use the tools of automation (Ansible, Arista CloudVision, Python, DCNM/ACI, etc.) I think there's not as much talk about some of the fundamental concepts, motivations, and how to address the "fear and loathing" of automation that the networking community can sometimes express regarding automation.…
