Today on Heavy Networking, all about improving email security with SPF (Sender Policy Framework), DMARC (Domain-based Message Authentication, Reporting & Conformance), and DKIM (Domain Keys Identified Mail). Our guest is Alex Blackie. He wrote an article on Email Authenticity 101 that I thought explained these topics really well. If you're a domain manager, you should listen to this one, even if you don't route mail through your domain. You can keep the bad guys from spamming in your name!

Ethan Banks & Ned Bellavance have a tech discussion with CEO Doug Murray and CTO Vishal Jain about multi-cloud security startup Valtix. Along the way, we find out that Valtix is a cloud-delivered security control-plane paired with a data-plane of enforcement points (sort of firewalls, but not exactly) delivered between any two points in the cloud you need them. Engineers should walk away from this chat with a solid idea of Valtix architecture and how it fits into their cloud design.

How does a company building a product from an open-source project get off the ground? How does it communicate its value, attract contributors, and develop a user base? And how does it spread the word without turning off engineers with typical tech marketing? Guest Emily Omier is a positioning consultant who helps companies and projects get it right.

Internet exchange points are networks you can use to connect to some other exchange participant. Sounds like maybe that’s a service provider thing, and it can be. But IXPs are useful for businesses, too. In this episode of Heavy Networking, we’re going to learn about IXPs, and non-profit IXPs in particular.

Today on the Day Two Cloud podcast we have a sponsored show with Akamai and a customer, IBM Cloud. When IBM rebuilt its Cloud Console from a monolithic application to microservices, the company turned to Akamai to help improve application performance while also supporting routing, failover, and availability across six global data centers. We get details from Pavel Despot, Sr. Product Marketing Manager at Akamai; and Tony Erwin, Senior Technical Staff Member/Architect at IBM.

On today's sponsored Heavy Networking we talk with DriveNets about why it’s time to take the disaggregated model--where you buy whitebox hardware and put a network operating system of your choice on it--seriously. Along the way, we’re going to hit DriveNets network architectures and operating models, and get you thinking about why disaggregated networking might make sense for you.

Today's Day Two Cloud sponsored episode dives into software-defined interconnects. The big idea is that you go up to a Web browser, click a few times, and now you've got a circuit stood up between your data center and AWS, or between you and a business partner, and so on. We'll get into the details about how it's done with Console Connect, a PCCW Global company.

Every once in a while, I get questions from random internet folks who want me to do their homework for them. They want me to provide them with detailed technical information, solve their complex design problem, or curate content on a difficult topic so that they don’t have to do the sifting.
While I like to help folks out as much as anyone (and often do), I usually ignore these sorts of questions. Why? Partly, I don’t have enough time to fix the internet. Partly, I like to get paid for consulting. But more importantly, the best technologists first try to solve their own problems.
When interviewing candidates for technical positions, one of my questions is, “If you run into a problem you’ve never faced before, how do you solve it?” There are two typical answers.
I prefer to hire a person who first tries to figure things out. While I want neither a cowboy nor science experiments making their way into production, I Continue reading
Today's Day Two Cloud podcast discusses the challenges of stitching together a fabric across more than one public cloud. How do you architect a fabric given the constraints of each cloud? We also drill into the idea of API gateways. Our guest is Chris Oliver, a network architect at NI.
I surveyed 53 IT professionals about online IT training in August 2021. Most of the folks I interact with are networking & cloud infrastructure professionals, and the answers reflect that. 53 responses isn’t enough to draw hard and fast conclusions from, but I still believe there are interesting trends & individual comments worth thinking about.
By the way, if you’d like to submit your own responses, I left the survey open. I told Google Forms to not collect email addresses, so your responses are anonymous.
I believe Udemy is so popular because it’s a great platform to Continue reading
Like anything in the world of IT, TLS has gone through various versions. TLS 1.1 and 1.2 are still commonly used, but TLS 1.3 is really where it’s at. Our guest is Ed Harmoush.

On today’s Heavy Networking, we drill into VMware’s vRealize Network Insight (vRNI) to learn how it provides end-to-end monitoring, how it uses flow records and other data sources, and its architecture. We’ll also discuss modeling/digital twin capabilities, and applying vRNI to security, troubleshooting, and other use cases. VMware is our sponsor.
