Last week I had the opportunity to join John Troyer on the VMware Communities podcast. My purpose, as John put it when he invited me, was to “gently introduce” the community to the idea of network virtualization, which is where I now spend most of my time since joining VMware in early February. emphasis mine).
All of Cisco’s major vendors are lined up in support of VMware’s NSX software based virtualization solution. F5 – Security/LoadBalancing. VMware already produced a great post on how to leverage NSX in a Cisco UCS environment. Network Cisco NSX VMWare' The list includes a who’s who of Cisco competitors.
Thomas Graf recently shared how eBPF will eliminate sidecars in service mesh architectures (he also announces the Cilium Service Mesh beta in the same post). Baptiste Collard has a post on Kubernetes controllers for AWS loadbalancers. Eric Sloof drew my attention to a VMware white paper on paravirtual RDMA devices on vSphere.
Bruce Davie and Martin Casado (with Nicira, now part of VMware) have written a post comparing the VXLAN and STT tunneling protocols. I might have mentioned this before, but Ken Pepple’s OpenStack Folsom architecture post is just awesome. Feel free to share something in the comments! Cloud Computing/Cloud Management.
HPs BladeSystem Matrix architecture is based on VirtualConnect infrastructure, and bundled with a suite of mostly existing HP software (Insight Dynamics - VSE, Orchestration, Recovery, Virtual Connect Enterprise Manager) which itself consists of about 21 individual products. .” But how revolutionary and simplifying are they?
The next step is to define in software the converged network, its switching, and even network devices such as loadbalancers. Provisioning of the network, VLANs, IP loadbalancing, etc. Gartner and others agree - this is the next wave in data center architecture. This permits physically flatter networks.
Some folks from Nicira (now part of VMware) recently published a blog post discussing the OVSDB IETF draft (see here ). This is an awesome overview of the OpenStack Folsom architecture , courtesy of Ken Pepple. In any case, this article by Frank Denneman on Storage DRS loadbalancing frequency might be useful to you.
Using 1 GbE would have required too many ports, too many cables, and too many switches; 10 GbE offered Expedient a 23% reduction in cables and ports, a 14% reduction in infrastructure costs, and offered a significant bandwidth improvement (compared to the previous 1 GbE architecture). Note that there are trade-offs as a result.)
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. Vladan Seget shares how to create a VMware ESXi ISO image with the latest patches. Servers/Hardware. Nothing this time (sorry!).
Looking for a step-by-step install guide for VMware NSX? Ray Budavari—who is an absolutely fantastic NSX resource—has a blog post up on the integration between VMware NSX and vRealize Automation. William Lam breaks down the real value of loadbalancing your PSC in this in-depth article. Networking. Kubernetes cheat sheet?
This is an interesting deep dive into Intel’s “Ice Lake” Xeon SP architecture. Rudi Martinsen has an article on changing the Avi loadbalancer license tier (this is in the context of using it with vSphere with Tanzu). (And since Kevin didn’t define TDP—shame, shame!—see A severity score of 9.9
Bernd Malmqvist talks about Avi Networks’ software-defined loadbalancing solution, including providing an overview of how to use Vagrant to test it yourself. Different design and architecture considerations apply in each instance. Cormac Hogan walks through setting up the Minio object store on top of VMware vSAN.

David Holder walks through removing unused loadbalancer IP allocations in NSX-T when used with PKS. Systango has this high-level overview of serverless application architecture along with some pros/cons, use cases, etc. Wil van Antwerpen talks about how to create a macOS Catalina VM using VMware Fusion. Virtualization.
Whatever DNS name you supply for controlPlaneEndpoint —and it should be a DNS name and not an IP address, since in an HA configuration this value should point to a loadbalancer, and IP addresses assigned to AWS ELBs can change–will also be added as a Subject Alternative Name (SAN) to the API server’s certificate.
