Datanauts 142: Cloud-First Networking With Big Switch Networks (Sponsored)

You ve got your traditional on-premises network. You know how it works. Lots of manual configuration and ticket-y stuff to get the job done when someone needs something.

And then you ve got your cloud network. You don t worry about that one as much. The devs provision what they need automatically, hitting APIs as they go, and you keep tabs on things from a watchful distance, helping out as needed.

What if you could operate your on-premises network like you do your public cloud network? What if your hybrid cloud was operationally consistent? Today on the Datanauts, sponsor Big Switch Networks makes some pretty big hybrid cloud networking announcements, and we quiz them on the why and how.

Our guest is Kyle Forster, founder of Big Switch.

We talk about Big Switch’s new products, including the ability to create an on-premises VPC within Big Switch’s data center fabric. The goal is to provide the same operational constructs within your own data center as you’d get in a public cloud like AWS, Azure, or Google.

Datanauts 141: Managing Cloud-Native Applications

Cloud native applications are designed to be managed by software in all stages. This includes ongoing health checks as well as initial deployments. Human bottlenecks should be eliminated as much as possible in the technology, processes, and policies.

That quote is from the O Reilly book Cloud Native Infrastructure. On today s Datanauts episode, we talk to Justin Garrison, one of the authors and a senior systems engineer.

We dive into the chapter about managing cloud native applications, including a general conversation about the definition of a cloud-native app–that is, an application managed by software rather than humans.

Then we discuss the challenges of managing a microservices architecture, explore the concept of sidecar proxies, and walk through the process of deploying a new cloud application into production.

We also look at troubleshooting tools and techniques, and examine the necessity of service discovery and resource scheduling.

Datanauts 140: Exploring End User Compute

There s a lot to be said about consuming technology remotely. Heck, the cloud is just that – someone else stands up infrastructure and services, and you consume them.

But what about for the desktop environment, which for many is their main working environment and something of a tug-of-war when it comes to ownership, management, and administration?

In today s episode of the Datanauts, join us as we de-mystify the exotic world of End User Compute, or EUC.

Our guest is Sean Massey, Senior Technical Architect at AHEAD. You can follow him on Twitter at seanpmassey and check out his blog at

We discuss what EUC encompasses, including technologies such as VDI as well as mobile devices, laptops, and desktops. We also look at how SaaS and cloud apps affect end users and application delivery, and explore the impact of EUC/VDI on the data center.

Datanauts 139: Getting AWS Security Right

AWS security issues show up in tech news fairly often. Today, we talk with someone who wrote about AWS services other than S3 that were found exposed to the public. Could that be some of your services?

Could be. The numbers are pretty impressive. Stay tuned, and find out how to determine whether or not your EBS snapshots, RDS snapshots, AMIs, or ElasticSearch clusters are accidentally public.

Our guest is Scott Piper, an AWS security consultant for Summit Route. You can follow him on Twitter at @0xdabbad00.

We start by exploring the types of AWS resources that can be unintentionally exposed to the public Internet, how to find them, and how to lock them down.

Then we talk about general practices such as vulnerability scanning, how to minimize human error when configuring AWS services, and drill into options such as CloudMapper and Security Monkey, open-source tools to help administrators find and control AWS resources.

Datanauts 138: What’s Up With Ethernet Fabrics?

Today on the Datanauts podcast, we review the state of Ethernet fabrics in 2018.

Between 2010 and 2012, before SDN became the new marketing hotness, it seemed like vendors were churning out Ethernet fabric products for the data center. Everyone had at least one fabric, and some had two or three.

As time has marched on, many of those Ethernet fabrics have dropped off the map. To catch us up and review what Ethernet fabric means today is Stefan Fouant. Stefan is the Chief Architect at Copper River Technologies, a Juniper Ambassador, a quadruple JNCIE, and author of the book Day One: Junos Fusion Data Center Up and Running.

We look at the status of Ethernet fabric protocols such as TRILL and SPB. We also dig into BGP EVPN, the latest hot fabric.

We also discuss the characteristics of a fabric, look at reasons why a fabric might make sense in your data center, and explore inter-fabric connectivity.

Datanauts 137: Automating Infrastructure As Code With Terraform

The robotic production facilities on board the Datanauts’ dreadnought cruiser are really great at making scout drones for identifying rich mineral deposits. Sadly, our probe production numbers are fairly low right now, because every single build is done by hand.

Blasphemy! We need a way to simply define the end state of our drone creation and then let an orchestration engine handle all of the building. Plus, if the design changes, we need to make sure all of the existing drones are retrofitted to take advantage of the new improvements! What can be done?!

Our guest today is Ned Bellavance. We pick Ned’s brain about infrastructure as code and his hands-on experience with HashiCorp’s Terraform.

Datanauts 136: ChatOps Using PoshBot With Brandon Olin

On this episode of Datanauts, we chat with Brandon Olin, the creator of PoshBot, a PowerShell based chatbot for ops teams. What does PoshBot do? How was PoshBot built? How do chatbots impact Brandon’s delivery model?


Bots have been around for a long time. They re really handy, too, often being able to answer simple questions by submitting a special command that has some sort of prefix or identifier associated with them. Especially if you re on Twitch and want to know how long your favorite streamer has been online.

Maybe that isn t the most helpful thing in the world, but what if we changed the narrative to be all about operations and how talking to a bot (with your peers watching) could actually up-level your day-to-day enjoyment of IT?

That’s our conversation today.

What is PoshBot?

PoshBot is a chat bot written in PowerShell. It makes extensive use of classes introduced in PowerShell 5.0. PowerShell modules are loaded into PoshBot and instantly become available as bot commands. PoshBot currently supports connecting to Slack to provide you with awesome ChatOps goodness.

Datanauts 135: An Introduction To Edge Computing

It turns out you can t do it all in the cloud. And thus, we have the rise of edge computing, in which data is collected, processed, and analyzed close to the source of its creation and close to where people and systems need it.

The goals of edge computing include improving performance, reducing the costs and time of data transmission, and creating new applications to take advantage of that data.

Our guide to edge computing is Alex Marcham. Alex is a technologist, writer and researcher. You can find his work at

We level-set with a working definition of edge computing, examine the notion of locality and what it means for edge computing, and discuss latency issues.

We explore edge computing use cases such as industrial processes and video surveillance, and dive into the infrastructure that drives this technology.

Datanauts 133: Perfecting The Job Hunt

Whether by choice or circumstance, it’s inevitable you’ll find yourself looking for a new job.

On today’s Datanauts episode we break down the job hunt process to help you understand what you want, what you have to offer, and how to make the most of your application.

Our guest is Doug Lane, a tech/ops professional who’s been working in IT for 25 years. He’s also recently gone through the process of finding and getting a new job.  You can follow him on Twitter at @debuggist.

Doug shares his experiences and tips about how he approached the job search. We start by talking about honestly understanding your own strengths and weaknesses, and then thinking about what kind of job it is you really want.

We also discuss how to evaluate job descriptions, and how to nail the application process.

Datanauts 132: Unit Testing For Fun And Profit

While performing a routine sensor sweep of the Gargleblaster nebula, the crew of the Datanauts starship noticed that many of the tasks are manual in nature and could, with a little effort, be automated with some scripting.

However, every time we moved on from one part of the nebula to another, a different error would crop up with the script s code. Isn t there some way that we can automatically test our code to make sure that more time is spent drinking a frothy ale instead of all this debugging?

On today’s episode with talk with Adam Bertram, a Microsoft MVP and author of The Pester Book.

He is currently a Senior Systems Automation Engineer working with PowerShell, Desired State Configuration, and various other DevOps tools to coordinate reliable software deployments for a biotech company. You can find his work at

We start by defining a unit test for scripts, and how unit testing differs from integration, functional, regression tests, and others.

Then we dive into why you’d want to test your scripts (testing isn’t just for developers!), and how to create these tests.

We also talk about the notion of test-driven development, and dive Continue reading

Datanauts 131: Masters And Mentorship

Today on the Datanauts podcast, we land on planet Mentorship to drive around in our exploratory rovers. Why? Mentoring came up on Twitter a while back.

Some of you are for it. You invest in your co-workers and your organization by sharing with others what you know. Some of you are against mentoring, arguing that you don t have the time and aren t getting paid to teach other people.

And then the Twitterverse connected us to Don Jones, who wrote a book called, Be The Master. Seems like a great excuse to fire up the microphone on our rovers and explore planet Mentorship in more detail.

Besides being an author, Don is an an IT pro and PowerShell expert who has created a variety of PowerShell training materials.

We talk about how a master/apprenticeship approach can be more effective than formal education, selfish reasons for being a mentor, how to address imposter syndrome, and how to get support for mentorship at work.

Datanauts 130: The Good, Bad And Ugly Of The VAR Life

If you work for a Value Added Reseller (VAR) as an engineer, the value being added is YOU.

What is VAR life? Projects, customer meetings, deadlines, bills of materials, RFP responses, and trying to turn the promises of sales unicorns into an actual design you can install for the customer.

We’ve worked for VARs at one time or another, as has our guest Eric Gullickson, who is now Enterprise Architect at Vortex Optics. We thought we d run down the good, the bad, and the ugly of the VAR life on this episode of the Datanauts podcast.

We start the show by distinguishing the different roles a VAR can have. Then we dive into the good, which includes access to new technology, paid certifications, a flexible work schedule, and exposure to a wide variety of businesses and operating environments.

For the bad, the Datanauts and Eric discuss the blunt reality that you have to generate profit, and you may find yourself having to navigate the competing interests of manufacturers, sales, distributors, and customers.

On the ugly side, we swap stories about greasy salespeople, bad project management, and other nightmares.
