It has been becoming increasingly clear – anecdotally at least – just how expensive it is to train large language models and recommender systems, which are arguably the two most important workloads driving AI into the enterprise. …
Counting The Cost Of Training Large Language Models was written by Timothy Prickett Morgan at The Next Platform.

Modularization is a crucial part of network design because it supports interchangeability, reduces the size of failure domains, and controls security domains. One critical aspect of modularization is functional separation, which argues for separating services onto specific physical and logical resources. Kevin Myers joins Tom Ammon and Russ White on this episode of the Hedge to discuss the theory and importance of functional separation in network design.
In today's episode of Kubernetes Unpacked, Michael catches up with Steve Buchanan, Principal Program Manager at Microsoft, to talk about using GitOps and Azure Kubernetes Service (AKS) to automate the building and deployment of applications. Microsoft has been working incredibly hard on AKS, including integrating different tools and platforms to make the lives of DevOps and Platform Engineers easier.

In this episode, Ed, Scott, and Tom talk about DNS and IPv6. We cover legacy IPv6 brokeness and DNS, how DNS performs over v6, and how DNS works with v6-only networks.

CONTAINERlab is a Docker orchestration tool for creating virtual network topologies. The sflow-rt/containerlab project contains a number of topologies demonstrating industry standard streaming sFlow telemetry with realistic data center topologies. This article extends the examples in Real-time telemetry from a 5 stage Clos fabric and Real-time EVPN fabric visibility to demonstrate visibility into IPv6 traffic flows.
docker run --rm -it --privileged --network host --pid="host" \
-v /var/run/docker.sock:/var/run/docker.sock -v /run/netns:/run/netns \
-v $(pwd):$(pwd) -w $(pwd) \
ghcr.io/srl-labs/clab bash
Run the above command to start Containerlab if you already have Docker installed. Otherwise, Installation provides detailed instructions for a variety of platforms.
curl -O https://raw.githubusercontent.com/sflow-rt/containerlab/master/clos5.yml
Download the topology file for the 5 stage Clos fabric shown above.
containerlab deploy -t clos5.yml
Finally, deploy the topology.
docker exec -it clab-clos5-h1 iperf3 -c 2001:172:16:4::2
Each of the hosts in the network has an iperf3 server, so running the above command will test bandwidth between Continue reading
After VMware launched DPU-based acceleration for VMware NSX, marketing-focused websites frantically started discussing the benefits of DPUs. Although I’ve been writing about SmartNICs and DPUs for years, it’s time for another closer look at the emperor’s clothes.
DPU (Data Processing Unit) is a fancier name for a network adapter formerly known as SmartNIC – a server repackaged into an interface card form factor. We had them for decades (anyone remembers iSCSI offload adapters?)
