The Fat Pipe - All Packet Pushers Pods

Today's Tech Bytes podcast explores active and passive monitoring techniques employed by sponsor AppNeta to monitor performance and end user experience on 100Gbps links. Our guests are Adam Edwards, Chief Customer Officer; and Mike Hustler, VP of Engineering at AppNeta.

The latest Network Break covers Fortinet's acquisition of endpoint security company EnSilo, digs into Gigamon's new network detection and response product, covers Extreme Networks' launch of ExtremeCloud IQ, reports on the latest tech financial results, and more.

TRex is an open source traffic generator backed by Cisco. Joining us on Heavy Networking today is Hanoch Haim, Principal Engineer with Cisco, and the lead developer on the TRex project.

This is not a sponsored show. I heard about TRex from an audience member.

I thought it was a really interesting open source alternative to commercial traffic generators that cost six figures. I reached out to Hanoch, and he was kind enough to join me for this episode to talk about TRex.

We discuss:

* How TRex works

* Use cases for traffic generation in testing

* How to deploy TRex

* Performance limits

* Why Cisco put this project into open source instead of selling it

* More

Today's episode explores how the US federal government views IPv6 adoption. We also explore the use of IPv6 by the U.S. Department of Defense, including innovations, and how the DoD's use affects its work with civilian entities. Our guest is Jeremy Duncan, founder and leading partner of the consultancy Tachyon Dynamics.

How does technical implementation and user feedback shape a cloud-based solution? When is it time to make a significant change in your design? And how do you know you’re headed in the right direction? This Day Two Cloud podcast episode tackles these questions with guest Michael Fraser, co-founder and CEO of Refactr.

Today's Network Break examines new campus and data center switches from Aruba, looks at new SD-WAN gear from Riverbed, discusses Teridion PoPs in China for SD-WAN, explores financial results from Juniper and AWS, and much more. Guest Ed Horley joins as guest commentator.

Today on Heavy Networking we talk security, both on premises and in the public cloud.

The network you build and run on premises and in the cloud are expressly designed to connect users and customers to applications and data, but they’re also a vehicle for malware, exploits, and intruders.

The network is being asked to do more filtering, more scanning, more blocking, more decision-making to try keep out the bad stuff, but we’ve also seen the limits of anti-virus, anti-malware, intrusion prevention, and Next-Gen Firewalls; even if these products are 99.999 percent effective, one mistake is all an attacker needs to get a toehold.

On today’s sponsored show we’re going to talk with ExtraHop about network detection and response (NDR), with a focus on public cloud. Our guest is ExtraHop founder and CTO Jesse Rothstein.

He’s here to talk about how NDR differs from prevention, how to use it in the cloud, ExtraHop’s ability to take advantage of native cloud traffic mirroring, and more.

We discuss:

* The shift in security from prevention to detection

* How to leverage the network as a source of ground truth for security investigations

* Getting useful visibility in hybrid environments

* The benefits of cloud-native traffic mirroring

* Dealing with information overload

* Behavioral modeling and analysis

* Traffic decryption challenges and solutions

* More

This is, sadly, the final episode of the Datanauts podcast. Chris Wahl and I had an extraordinary adventure busting IT silos, comparing notes, lobbing things over the wall at each other, and trying to sort out what the new IT stack looks like. Why? We’ll get there. Read on.

But There Was So Much More To Talk About!

For all of us in IT, the changes over the last five years have complicated our lives and introduced us to new tradeoffs.

* Automation abstracts away important details while speeding configuration.

* Orchestration enables application elasticity, but only if the app has been architected to function that way.

* Cloud postulates that you don’t need infrastructure design anymore, but very public outages, along with common sense, have busted the #noops myth.

In other words, we’re still figuring it out. All of us. Engineers. Architects. Developers. End users. Vendors. Open source groups. Standards bodies. Consortiums. Training companies. Resellers. The Datanauts mission isn’t really over, at least not in principle. Chris and I could keep podcasting indefinitely, having great conversations with people from all over the industry. There is much silo busting yet to be done.

Reality’s Cold, Fishy Slap To The Face

Reality sometimes gets in the way of what we’d like to do, though. That reality has, in the best possible way, intruded on Chris’ world. He’s got new opportunities both personal and professional that make it impossible for him to keep going as the Datanauts co-host.

And so, that’s it. We’re aiming our infrastructure rocket into the IT universe and heading “out there.” That-a-way. Chris explains more in the recording for those who want the details.

Filling The Void In Your Heart

Over the years, many of you told us that Datanauts was a favorite. And now, we’re taking that favorite away from you. Perhaps you’re angry…or weeping uncontrollably. Maybe you just threatened a pet. A coworker cubicles away might have felt your stress ball land on their head as you hurled it over the top.

Don’t be like that. Sure, Datanauts is leaving a void in your heart, but we hope to fill that void with the Day Two Cloud podcast. Author and PluralSight course creator Ned Bellavance has been running this show on the Packet Pushers network since the start of 2019, and I have now joined him as co-host.

Day Two Cloud will be a weekly podcast starting in November 2019, and we’re covering cloud operations of all kinds. Private. Hybrid. Multi. And of course, public. IaaS, PaaS, SaaS, serverless. Automation. Orchestration. Security. Conversations with vendors, engineers, and industry friends–all with a healthy dose of humor and cynicism.

Datanauts Forever!

We won’t be taking the catalog of Datanauts shows away. The archive of published shows will remain available here. And of course, Chris is still a social human you can interact with! If you want to keep up with Chris, you can follow him on Twitter or check out his blog at Wahl Network.

Our deepest thanks to all of you that subscribed and listened. Datanauts was one of the most downloaded channels on the Packet Pushers podcast network. We’ll miss it as much as you will.

Welcome to Heavy Networking from the Packet Pushers Podcast network. Today’s show is all about Digital Transformation.

CIOs, executives, analysts, and product managers talk about digital transformation the way exercise junkies talk about CrossFit: as the way and the truth and the blueprint for…what, exactly?

Businesses already use technology. Things are pretty well digitized. Employees have laptops and mobile devices, and IT teams build and run elaborate systems to move and process data.

Does digital transformation just mean adopting the latest gadget and moving data faster, or is there something more?

That’s the question we’ll explore on today’s episode. We’ve brought on several guests to help puncture the hot air balloon of digital technology and see if there’s anything useful inside: Paul Beyer, Infrastructure Architect; Tobias Metz, Consultant Network Engineering & Training Coordinator; and Emma Cardinal-Richards, Senior Network Architect.

In our conversation we:

* Try to assemble a working definition of digital transformation

* Explore how the idea of digital transformation differs from previous eras of technology adoption

* See if we can tie the notion of transformation to particular technologies

* Discuss the impacts of digital transformation on engineers
