Technology Short Take 99
Welcome to Technology Short Take 99! What follows below is a collection of various links and articles about (mostly) data center-related technologies. Hopefully something I’ve included will be useful. Here goes!
Networking
- David Gee makes the connection between coffee and network automation. No, really. It’s worth reading.
- Matt Oswalt, one of the co-authors of our recently-released network automation book from O’Reilly, recently tackled the topic of running Kubernetes with Tungsten Fabric (formerly known as OpenContrail). A network engineer using AWS and CloudFormation? Yep, get used to it folks—it’s where the industry is headed.
- Vince Power provides a high-level overview of some of the key principles underlying Kubernetes networking.
Servers/Hardware
Sorry, I don’t have anything for you. Feel free to send me links you’d like me to consider for inclusion in the next Tech Short Take!
Security
- Mike Foley talks about new support for Virtualization Based Security (VBS) and Credential Guard in vSphere 6.7.
- Chris Short examines some of the security-related aspects of the adoption of containers.
- The Kubernetes community reflects on fixing the subpath volume vulnerability in Kubernetes.
- Michael Ducy of Sysdig outlines a configuration combining Sysdig Falco, NATS, and Kubeless for “active Kubernetes security.” While the post Continue reading
A recent report found 21 percent of open source serverless projects contained at least one critical vulnerability or misconfiguration.


Many Chinese service providers are reliant upon ZTE’s optical gear for their transport networks and backhaul. And switching to another vendor is not that easy.
With service-mesh technologies, such as Envoy and Istio, web services can effectively talk to each other and become building blocks to create applications.
One analyst said Ciena was the source of the current price war in the optical networking space.
