If you’re new to this process, let me break this down for you: When you first log in to your cloud services provider console, you have to configure a Virtual Private Cloud (VPC), which requires networking knowledge. You have to launch the virtual servers, which means you need to: Choose an operatingsystem.
Erik Smith, notably known for his outstanding posts on storage and FCoE, takes a stab at describing some of the differences between SDN and network virtualization in this post. OperatingSystems/Applications. Virtualization. There’s some additional information on the Quantum release on Folsom here.
The first concept that Recep discusses is network virtualization. He believes that network virtualization is primarily about decoupling network services from the underlying network infrastructure. The specific terminology involved is that the virtual switches become a VTEP, a virtual tunnel end-point.
I have a fairly diverse set of links for readers this time around, covering topics from microchips to improving your writing, with stops along the way in topics like Kubernetes, virtualization, Linux, and the popular JSON-parsing tool jq.

Romain Decker has an “under the hood” look at the VMware NSX loadbalancer. This graphical summary of the AWS Application LoadBalancer (ALB) is pretty handy. OperatingSystems/Applications. Virtualization. Servers/Hardware. Nothing this time (sorry!).
Eric Sloof mentions the NSX-T loadbalancing encyclopedia (found here ), which intends to be an authoritative resource to NSX-T loadbalancing configuration and management. OperatingSystems/Applications. Virtualization. Here’s hoping that I found something useful for you! Networking.
OperatingSystems/Applications. Here’s a Windows-centric walkthrough to using Nginx to loadbalance across a Docker Swarm cluster. As an aside, I do find it fascinating that new storage startups often emerge with support for Linux first, then add other operatingsystems afterward.). Virtualization.
Bernd Malmqvist talks about Avi Networks’ software-defined loadbalancing solution, including providing an overview of how to use Vagrant to test it yourself. OperatingSystems/Applications. Virtualization. Julia Evans provides a quick overview of Wireshark. Mike Foley walks you through configuring TPM 2.0
Xavier Avrillier walks readers through using Antrea (a Kubernetes CNI built on top of Open vSwitch—a topic I’ve touched on a time or two) to provide on-premise loadbalancing in Kubernetes. OperatingSystems/Applications. Virtualization. Servers/Hardware. Cabling is hardware, right?
The “TL;DR” for those who are interested is that this solution bypasses the normal iptables layer involved in most Kubernetes implementations to loadbalance traffic directly to Pods in the cluster. OperatingSystems/Applications. Virtualization. Unfortunately, this appears to be GKE-specific.
Here’s a quick look at using Envoy as a loadbalancer in Kubernetes. It’s a good starting point for thinking about operating your own active-active architecture. OperatingSystems/Applications. Virtualization. I hope this collection of links has something useful for you! Networking.
VPCs, or Virtual Private Clouds, are Amazon’s software-defined networking mechanism for workloads running on AWS.). Viktor van den Berg writes on deploying NSX loadbalancers with vRA. OperatingSystems/Applications. Virtualization. Speaking of Buildah…here’s a post from Tomáš Tome?ek
Continuing on that Envoy theme, you may find this article by Matt Klein—one of the primary authors of Envoy—helpful in understanding some of the concepts behind modern loadbalancing and proxying. OperatingSystems/Applications. Virtualization. Servers/Hardware. Good stuff!
I have a fairly diverse set of links for readers this time around, covering topics from microchips to improving your writing, with stops along the way in topics like Kubernetes, virtualization, Linux, and the popular JSON-parsing tool jq along the way.

Check out these articles talking about IPVS-based in-cluster loadbalancing , CoreDNS , dynamic kubelet configuration , and resizing persistent volumes in Kubernetes. OperatingSystems/Applications. Virtualization. Nathaniel Avery shares a tip on saving some money by using the right servers on Azure.
Containerization allows us to abstract the operatingsystem that our application runs on into the “container” that the application is running in, as well as any related dependencies. For example, for an application that runs in the JVM (Java Virtual Machine), we package the JVM into the container as well as the application.
This time around, the content is a bit heavier on cloud management and applications/operatingsystems, but still lots of good content all the way around (I hope, anyway). tech preview of virtual networks for Docker. OperatingSystems/Applications. Virtualization. Networking. Servers/Hardware.
and their product (VirTool Network Analyzer) is aimed at providing some operational visibility into OpenStack virtual networks. I saw a demo of the product—it looks quite handy, and provides a pretty fair amount of information to help operators figure out what’s happening “under the covers. Virtualization.

David Holder walks through removing unused loadbalancer IP allocations in NSX-T when used with PKS. OperatingSystems/Applications. Virtualization. These two articles are interesting (to me) because they combine both network automation and Kubernetes. I’m looking forward to seeing how NaaS evolves.
OperatingSystems/Applications. Virtualization. William Lam breaks down the real value of loadbalancing your PSC in this in-depth article. This is an older post on OpenStack availability zones and host aggregates , but useful nevertheless (for me, at least). Want to run Docker Swarm on Azure? Good write-up.
Sure Virtualization Seems Neat In The Beginning, But…. To read the IT trade journals or speak with CIOs you’d think that we’ve all found the magic silver bullet that IT’s been looking for during the past few years: server virtualization. Virtualization has its own set of problems and we need to have a talk….
