The Fat Pipe - All Packet Pushers Pods

How do you provide highly available, scalable services to a cloud-native app that’s been architected with microservices? Just stand up a whole lot of virtual IPs and pools? Not exactly.

You need both more capability and more automation. You need a service mesh. And today on the Datanauts podcast we’re joined by sponsor AVI Networks to find out what a service mesh is and how it supports cloud-native applications.

We’re joined by Ashish Shah, Senior Director of Products at AVI Networks.

Broadly speaking, a service mesh ensures that the various components and services that make up a widely distributed application can reach each other using techniques such as service discovery, load balancing, and handling failures.

The Datanauts and Ashish drill into the major concepts of a service mesh, examine critical components and the architectural approaches, and explore the AVI Networks platform.

Visibility and telemetry are key to getting real-time insights into network operations and performance.

Today on this sponsored Priority Queue, Nokia Deepfield shares real-world use cases on how companies are using Deepfield to see traffic as it crosses every link, get application context, and then make the right decisions–including automated actions–to give customers the best performance possible.

Our guest is Tony Kourlas, Director of Product Marketing at Nokia. We talk with Tony about how an online gaming company, video content providers, and ISPs use Deepfield to gather telemetry, analyze the data, and then take informed actions. We also look at the DDoS mitigation use case.

In addition, we dig into how Deepfield gathers data, the types of data it gathers, and how it interacts with other systems such as SDN controllers to automate responses.

It’s back to the flea market of ideas that is the Web for the latest in the Datanauts’ ‘Found On The Internet’ series.

Chris and Ethan sift through online baubles, notions, and curiosities to find just the right accent pieces to decorate the bridge of the Datanauts Starship.

Our finds for Series 3 include container adoption, storage network topologies, PowerShell, IT blame culture, and so much more to delight and amaze!

Our series of podcasts recorded live at IETF 99 continues with a conversation about network automation and the YANG data modeling language.

Our guest is Sue Hares, a consultant and chair of the Inter-Domain Routing Working Group at the IETF. Sue also joined us for Weekly Show 355: What’s Wrong With BGP?

We talk about the costs of network configuration, in particular the software interfaces and hand-crafted, artisinal command lines that define the majority of how network devices are set up and operated.

We also dive into why network automation is getting more attention, and how YANG fits into the picture. And Sue makes a pitch for listeners to participate in IETF hackathons for learning, professional development, and as a way to get involved with the standards organization.

For more conversations about YANG and IETF hackathons, check out the Show Links below.

Tracking cloud costs seems like it should be pretty straightforward: you pay X cents per time unit per resource used.

But as cloud customers quickly learn, costs can get complicated pretty quickly. It can be hard to predict costs month by month, you may get billing surprises, and organizations can spend more than they need to.

Today on the Datanauts starship we’ve beamed aboard Corey Quinn, a cloud economist and consultant who helps customers understand their AWS bills and how to manage their spending. He’s the founder of Quinn Advisory Group, and also writes a free newsletter called Last Week In AWS.

We start the conversation by drilling into how AWS bills for its services, and then talk about how costs and billing tie back to business decisions. You have to understand why you’re moving into the cloud, and how you’re factoring your applications, to really understand what you’ll be spending.

We also explore reasons why bills grow unexpectedly, learn how to set alerts to catch overages, and discuss why the lowest bid for your cloud business shouldn’t be your primary decision point.

While our conversation focuses mostly on AWS, it applies to any public cloud offering.

The Packet Pushers’ Priority Queue series from IETF 99 continues with a conversation about whitebox switching at LinkedIn.

Shawn Zandi, principal infrastructure architect at LinkedIn; and Russ White, network architect at LinkedIn.

Greg Ferro and his guests discuss the architectural changes going on at LinkedIn, including a move to adopt whitebox switches.

They look at the drivers for whitebox adoption, including wanting to have more control over their infrastructure, the ability to rethink network design, the opportunity to get features they want (and remove ones they don’t), and potential cost savings.

They also explore the challenges that come with whitebox deployment and operations, and talk about the pros and cons of various network designs.

Today on the Datanauts, our infrastructure rocket navigates the rapidly expanding universe of cryptocurrencies–specifically Bitcoin and Ethereum–and the Blockchain distributed database. We also touch on the Grid+ project.

All of these topics could get their own episode (or more) so this is more of an introductory show than a deep dive.

But we’ve got three smart guests to help us make sense of it all: Mark D’Agostino, Managing Partner at ConsenSys Enterprise and Strategy Lead at Grid+; Karl Kreder, Director of Energy at ConsenSys; and Alex Miller, Software Engineer at ConsenSys and Software Lead at Grid+.

The Priority Queue returns to the IETF 99 conference to explore projects and standards being worked on within the IETF.

How do you get devices such as light bulbs and sensors join a network securely, make sure they’ve joined the right network, and that the network can be sure the device is what it claims?

That’s the general thrust of today’s episode, which looks at the ANIMA (Autonomic Networking Integrated Model and Approach) Working Group.

This working group aims to “…develop a system of autonomic functions that carry out the intentions of the network operator without the need for detailed low-level management of individual devices.”

Greg’s guest is Michael Richardson, an IETF member and Managing Editor at the Centre for Research and Experimental Development in Informatics Libre (CREDIL) in Canada.

In addition to ANIMA, Greg and Michael also discuss 6tisch and NETCONF.

Are you still hosting your own e-mail? Is it on Microsoft Exchange? Are you maybe a little sick of that?

What if you could outsource some of those pesky infrastructure problems to the cloud?

Well, of course, you can. Microsoft Office 365 would love to help you with that. Catch a ride on board the mail migration rocket on this episode of the Datanauts podcast.

Our guest is Theresa Miller. She’s founder of 24×7 IT Connection. She’s a consultant and analyst, and she also blogs and hosts the Current Status podcast.

Theresa and the Datanauts examine the business case for, and technology implications of, migrating from on-premises email to a cloud service.

They also look at the migration process and its impact on users, and discuss the operational challenges of co-existence when IT is managing both the premises system and the cloud service.

Can we accelerate the pace of change in enterprise IT?

That’s the topic for today’s Priority Queue. This episode, sponsored by VMware, was recorded live at VMware’s Future:Net conference on August 31, 2017.

Greg Ferro and Ethan Banks assemble a panel of networking experts and practitioners to discuss why technology change can be so difficult in the enterprise (product complexity, long buying cycles, process paralysis, and so on), and how organizations can spur change and innovation in their own environments.

Our guests are:

* Pere Monclus, CTO, VMware

* Jeremy Filliben – Principal Network Architect, Genworth Financial

* Tommy McNicholas – Solutions Architect at Technologent

* Truman Boyes – CTO Office, Head of Networks at Bloomberg
