The Everything Feed - All Packet Pushers Pods

The Full Stack Journey explores practical network automation, including tips for getting started and for self-motivation, with guest Anthony Burke.

Today on the Datanauts we’re talking about in-memory databases. The idea is that you can load up a host with lots of RAM, cram your database in there, and get more transactions due to the lower latency.

But if the system is distributed, you’ve strewn database parts across multiple hosts, so you lose some of that CPU-to-RAM latency advantage. Or do you?

It’s an interesting design problem with some complex constraints, and it’s the focus of today’s podcast. Our guests are Swapnil Bawaskar, principal engineer at Pivotal; and Jim Bedenbaugh, Advisory Data Engineer at Pivotal.

Swapnil, Jim, and the Datanauts define in-memory databases, describe how they differ from traditional databases, and talk about use cases. They drill into the system architecture for in-memory DBs, including hosts, distributed systems, and failure scenarios. They also discuss practical issues including general operations, metrics, and backup and restoration.

Today’s Priority Queue continues our discussions about network modeling and programmability. Our guest Michael Kashin has been working with YANG models, python, and a variety of supporting tools to programmatically install network device configurations, spending time with both Junos and IOS XE.

In his detailed series of posts on networkop.co.uk, Michael has painstakingly explored and explained how to work with network models, showing how they tie to the future of network configuration. In this episode, we discuss many of Michael’s discoveries.

If you skipped it, you might want to listen to Priority Queue episode 111 first, where I discuss YANG, NETCONF, and network model standardization efforts in the IETF with Benoit Claise. That would be a good foundation for today’s episode.

If you’ve listened to the Datanauts or read Chris Wahl’s blog, you know that he’s a big fan of PowerShell. On today’s episode, Chris shares his adventures at the recent PowerShell and DevOps Global Summit.

Chris and Ethan talk about just what PowerShell is, why the language is becoming so popular, its relationship to Ops (and a little Dev), and how folks can get started exploring all the glory that is PowerShell.

This Full Stack Journey episode focuses on expanding your knowledge of and skill with Amazon Web Services (AWS). Our special guest is Alex Galbraith.

This episode of the Full Stack Journey centers on automation, why automation is important, and how to get started. My guest is Jake Robinson, an automation specialist at VMware.

Today’s Priority Queue dives into three IETF draft projects around routing:

* BIER (Bit Index Explicit Replication), which describes a new mechanism for multicast forwarding

* RIFT (Routing In Fat Trees), a dynamic routing protocol for Clos and Fat Tree topologies

* BGP+SFC (BGP + Service Function Chaining), which describes the use of BGP as a control plane for service function chaining using a new address family

Ethan Banks is joined by Alia Atlas, a Distinguished Engineer at Juniper and a Routing Area Director at the IETF; and Antoni (Tony) Przygienda, a Distinguished Engineer at Juniper and chair of the IETF’s BIER project.

Alia and Tony will provide overviews of each project, discuss the problems they’re designed to solve and how they work, and update us on the status of each effort.

Strap in, because it’s going to get nerdy!

This podcast was recorded on site at the IETF 98 conference in March 2017 in Chicago. Thanks to Huawei, which covered travel and accommodations to enable the Packet Pushers to attend and record some shows and spread the news about what the IETF is up to.

Full Stack Journey episode 8 features Ivan Pepelnjak, well-known author, blogger, podcaster, and speaker. Ivan produces a phenomenal amount of content around networking and adjacent technologies.

Today on the Datanauts we explore the depths of vSphere 6.5 host resources to help you maximum performance of your virtual infrastructure and provide a deeper understanding of essentials such as CPU, memory, storage, and Non-Uniform Memory Access (NUMA).

Our guests are Frank Denneman and Niels Hagoort, authors of the forthcoming book “vSphere 6.5 Host Resources Deep Dive.”

You can follow the progress of the book and get updates and announcements via Twitter and Facebook. And for more nerdy goodness, check out Frank Denneman’s blog (including his NUMA deep dive series) and Niels’s blog Cloudfix.
