<p>In this episode, Avi Freedman joins us again to talk about "enrichment", or in other words, adding additional context to our more traditional network telemetry so that we can truly understand what's happening in our network and with application delivery. </p>

<p>For years, routing on the global internet has been built mainly on trust relationships. There has been little to protect the entire internet community from accidental or intentional spoofing of IP address spaces and autonomous systems, and there was very little governance protecting the security of routing among providers other organizations with an internet presence. </p><p><br></p><p>In this episode of Telemetry Now, Aftab Siddiqui, Senior Manager of Internet Technology for the Internet Society, joins us to discuss MANRS, or the mutually agreed norms for routing security, which was started specifically to set forth security principles and guidelines for routing security on the global internet.</p>

<p>Historically, the internet has operated on a sort of trust relationship. Trust among those advertising their own networks out to the world and trust from those learning about those networks. But there hasn’t been much to prevent anyone from advertising incorrect information, and therefore manipulate where others send their traffic sometimes to the extent that traffic might even be blackholed causing outages. In this episode of Telemetry Now, Job Snijders, Principal Engineer at Fastly and a prolific contributor to efforts securing global routing, joins us to talk about how we can secure global internet routing with technologies such as ASPA, RPKI validation, Peerlock, and to an extent, BGP Security. </p>

<p>Is data science, and specifically machine learning, just network industry marketecture, or do the process and workflows of ML actually solve real problems for network engineers working in the trenches? In this episode of Telemetry Now, Estefan Ortiz, Ph.D., joins us to talk about what ML has to do with network visibility and the truth of what it can do to solve real problems in networking. </p><p><br></p><p><strong>Key Takeaways</strong></p><ul><li>[00:39 - 03:10] Introduction to Estefan Ortiz</li><li>[03:15 - 04:27] The definition of data science</li><li>[04:30 - 06:38] Why the rise in discussions about data science across industries?</li><li>[06:39 - 09:52] A desire to solve networking problems in new ways, and how data and the types we use can help</li><li>[09:53 - 10:38] Machine learning, applied statistics, and figuring out the problem you're trying to solve</li><li>[10:57 - 13:41] Is this a solution looking for a problem, and solving for time series data</li><li>[13:41 - 17:16] Detecting patterns in problem solving, actionable insights tied to operational data</li><li>[17:16 - 18:57] An iterative approach to problem solving with different processes and trial and error</li></ul><p><br></p><p><br></p>

<p>Not too long ago, it seemed everyone's plan was to lift and shift an entire data center's worth of workloads to the public cloud. Today, the industry is starting to rethink that strategy and be much more thoughtful as to what should go in the public cloud, why, and how. In this episode, Ted Turner, a cloud solutions architect at Kentik, joins Telemetry Now to talk about the changing narrative around moving everything to the public cloud. </p><p><br></p><p><strong>Key Takeaways</strong></p><ul><li>[00:45 - 02:06] Meet Ted Turner</li><li>[02:07 - 04:10] Public cloud and the elephant in the room, cost savings</li><li>[04:15 - 06:35] Duped into thinking the cloud was cheaper, versus the utility today</li><li>[06:36 - 10:08] The complexity of the networking industry and costs associated</li><li>[10:10 - 12:51] Dropping costs dramatically.

<p>Network observability is a popular term in the industry right now, and everyone seems to have their own definition. In this episode of Telemetry Now, Avi Freedman, CEO, and co-founder of Kentik joins us to talk about what network observability is really all about, what makes it work, and what problems it solves for packet nerds and router jockeys trying to keep the lights on. </p><p><br></p><p><strong>Key Takeaways</strong></p><ul><li>[00:33 - 02:03] A shared love of Star Trek</li><li>[02:04 - 04:10] Observability predates network technology, and inferring status</li><li>[04:11 - 06:35] Visibility into all networks and observability as necessity</li><li>[06:35 - 09:44] Ingesting telemetry and extrapolating inferences from data</li><li>[09:48 - 11:19] Collecting everything that can be collected, in an ideal world everything would be collected</li><li>[11:22 - 13:54] Why are we correlating, normalizing, and standardizing data acquisition?
