This is the first in an occasional Datanauts series we’re calling “Found On The Internet.” The idea is to gather up things that we’ve read online that maybe don’t make up a full show, but that we want to talk about.

Today’s topics include the Future of Ops, CockroachDB, and OpenStack growing up.

Our guest to help us discuss these subjects is Rebecca Fitzhugh, Technical Marketing Engineer at Rubrik. She’s also an author and blogger.

On today’s episode the Datanauts rocket ventures into the treacherous asteroid field that is IT security.

And like an asteroid field, security is constantly in flux. We defend, and the attackers change tactics. We figure out the new attacks, and the rules change yet again. And so it is that the security architectures of old are not the security architectures of today. And the security architectures of today are not likely to be the security architectures of tomorrow.

Our guests are James Holland, a systems engineer; and Aaron Miller, a systems engineer manager. Both work for Palo Alto Networks, but this isn’t a sponsored show. The discussion traces the evolution of security architectures and approaches, the importance of application awareness, and the impact of virtualization, which can both create new risks and provide new opportunities.

We also look at where security is going, how cloud and virtualization will continue to shape your security infrastructure, and how skill sets will have to adapt to support more automation.

This episode of the Datanauts examines Identity and Access Management (IAM) in the context of AWS. A proper IAM framework is essential to ensure that the right people access the right resources in AWS, but setting up and managing policies can be…daunting.

The Datanauts are joined by Cole Morrison, a lead engineer at Fieldboom, who wrote a detailed series of posts on how to get a handle on IAM in AWS. They talk about why you want IAM in the first place, how it works, and then drill into setting up policies for AWS infrastructure.

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.

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.

The Datanauts rocket returns to the automation solar system for another detailed survey of the whys and hows of automation and coding in operations.

Our intrepid host for this voyage is Lauren Malhoit, a technologist, Cisco employee, and co-host of Cisco’s Techwise TV. She also blogs at AdaptingIT.

We talk with Lauren about APIs, scripting and coding (particularly in Python), and the debate about whether network engineers and other non-developer IT pros need to learn to program. Lauren also offers tools and tips for folks who want to get started with automation and programming.

Today on the Datanauts it’s email security. Lots of organizations have outsourced their email to the cloud, and for good reasons: Web access is ubiquitous, email infrastructure can be a pain to manage and secure, and email can take up lots of storage.

But there are also good reasons for keeping email in-house, including privacy and retention requirements, specific security needs, and the ability to maintain control over your infrastructure destiny.

On today’s episode we’ll discuss how to build a robust and secure in-house email infrastructure, talk about the importance of IPv4 and IPv6 support, explore technologies and protocols to validate email servers and thwart spammers, and explain the role of DNS in supporting secure email.

Our guest is Jacob Evans, Sr. Systems Engineer at WebstaurantStore.com. You can follow him on Twitter and check out his blog at www.jacobdevans.com.

Automation is the key to speed and scale, but networking has been slower to adopt automation tools and processes than other IT disciplines. Today’s Datanauts episode explores the current state of network automation to try to understand the challenges and limitations in networking, and how the industry is shifting.

Our guest is Ryan Booth, a senior data center engineer at a large financial services company. He blogs at Moving Ones & Zeros.

Ryan and the Datanauts talk about why the majority of networking equipment is still managed by the CLI; the emerging sets of tools, APIs, data models, and community projects that are emerging for network automation, and how network engineers can tackle configuration management and code management.
