TranscriptAnnouncer: Hello, and welcome to Screaming in the Cloud with your host, Chief Cloud Economist at The Duckbill Group, Corey Quinn. This weekly show features conversations with people doing interesting work in the world of cloud, thoughtful commentary on the state of the technical world, and ridiculous titles for which Corey refuses to apologize. This is Screaming in the Cloud.Corey: This episode is sponsored in part by our friends at Sysdig. Sysdig is the solution for securing DevOps. They have a blog post that went up recently about how an insecure AWS Lambda function could be used as a pivot point to get access into your environment. They’ve also gone deep in-depth with a bunch of other approaches to how DevOps and security are inextricably linked. To learn more, visit sysdig.com and tell them I sent you. That’s S-Y-S-D-I-G dot com. My thanks to them for their continued support of this ridiculous nonsense.Corey: Today’s episode is brought to you in part by our friends at MinIO the high-performance Kubernetes native object store that’s built for the multi-cloud, creating a consistent data storage layer for your public cloud instances, your private cloud instances, and even your edge instances, depending upon what the heck you’re defining those as, which depends probably on where you work. It’s getting that unified is one of the greatest challenges facing developers and architects today. It requires S3 compatibility, enterprise-grade security and resiliency, the speed to run any workload, and the footprint to run anywhere, and that’s exactly what MinIO offers. With superb read speeds in excess of 360 gigs and 100 megabyte binary that doesn’t eat all the data you’ve gotten on the system, it’s exactly what you’ve been looking for. Check it out today at min.io/download, and see for yourself. That’s min.io/download, and be sure to tell them that I sent you.Corey: Welcome to Screaming in the Cloud. I’m Corey Quinn. Today’s guest was on relatively recently, but it turns out that when I have people on the show to talk about things, invariably I tend to continue talking to them about things and that leads down really interesting rabbit holes. Today is a stranger rabbit hole than most. Joining me once again is @SheNetworks or Serena [DiPenti 00:00:51]. Thanks for coming back and subjecting yourself to, basically, my nonsense all over again in the same month.Serena: Thanks for having me back. Excited.Corey: So, you have a, I think study group is the term that you’re using. I don’t know how to describe it in a way that doesn’t make me sound ridiculous and describing and speaking with my hands and the rest. It’s a Discord, as the kids of today tend to use. There are some private channels on an existing Discord group, and we’ll get to the mechanics of that in a second. But it’s a study group for various Cisco certifications, which it’s been a while since I had one; my CCNA is something I took back in 2009. I’ve checked, it’s expired to the point where they can’t even look it up anymore to figure out who I might have been, once upon a time. What is this group and where did it come from?Serena: Yeah, so the Discord itself is kind
