We don’t make the firewall, we don’t make the F5 loadbalancer, we don’t make the Cisco router, but we make them better,” DeBell said. Related articles. DeBell says this is done by consolidating visibility of different solutions in one graphical representation. Find out more information on FireMon here. aviatnetworks.com).
They manage dedicated firewalls for us, but as far as loadbalancers we use the cloud. I wasn’t sure cloud loadbalancing would be right, for example, but they showed us the numbers. Featured Cloud Articles. Featured Modular Articles. ARCHIVED ARTICLES. A lot of providers won’t let us in their plans.
When Cluster API creates a workload cluster, it also creates a loadbalancing solution to handle traffic to the workload cluster’s control plane. For flexibility, Cluster API provides a limited ability to customize this control plane loadbalancer. On AWS, this mean creating an ELB and a set of security groups.
the system dynamically loadbalances their data across the machines. Related articles. He Writes: Dynamic partitioning of data across large dynamic numbers of machines. The only issue is that it needs to be dynamic so that as items are added or get â??busyâ?? t think theyâ??ve ve quite solved this yet. readwriteweb.com).

For now, though, I have a small collection of articles and links for your reading pleasure—not as many as I usually include in a Technology Short Take, but better than nothing at all (I hope!). Baptiste Collard has a post on Kubernetes controllers for AWS loadbalancers. Welcome to Technology Short Take #149! Networking.
I recently came across something that wasn’t immediately intuitive with regard to terminating HTTPS traffic on an AWS Elastic LoadBalancer (ELB) when using Kubernetes on AWS. Consider the following YAML, taken directly from the previously-referenced AWS Premium Support article: apiVersion : v1. kind : Service. port : 443.
The real problem is the configuration and management of network policy: stuff like QoS, VLANs, ACLs, NAT, VRFs, firewalls, loadbalancing, etc. This article was originally posted on blog.scottlowe.org. However, it seems to me that this isn’t the real problem. Please be sure to add vendor affiliations, where applicable.
Networking Lee Briggs (formerly of Pulumi, now with Tailscale) shows how to use the Tailscale Operator to create “free” Kubernetes loadbalancers (“free” as in no additional charge above and beyond what it would normally cost to operate a Kubernetes cluster). Thanks for reading! This is a handy trick.
There should also be built-in flexibility for fluctuations in traffic volumes; this could be done through loadbalancing to ensure that both standard and peak traffic volumes are adequately supported at all times. This appraisal should pinpoint any enhancements that are necessary to improve the network. Resultant issues.
A specific angle I want to address here is that of infrastructure automation ; that is, the dynamic manipulation of physical resources (virtualized or not) such as I/O, networking, loadbalancing, and storage connections - Sometimes referred to as "Infrastructure 2.0". a Fabric), and network switches, loadbalancers, etc.
While mTLS offers the most secure option, it requires custom tooling and is not yet supported by all loadbalancers. A few snippets from the technical blog: The misconfiguration can allow threat actors to bypass WAF protections and directly target web applications and loadbalancers over the Internet.
Here’s a quick look at using Envoy as a loadbalancer in Kubernetes. Having recently needed to dig into Open Policy Agent (OPA) , I took renewed interest in this slightly older article by Chip Zoller that compares OPA/Gatekeeper with Kyverno. I hope this collection of links has something useful for you! Networking.
Google also added this reference point: "For a sense of scale, this two minute attack generated more requests than the total number of article views reported by Wikipedia during the entire month of September 2023."
Mirantis published an article discussing a framework they built for bare-metal provisioning with OpenStack that allows OpenStack to place workloads onto bare-metal nodes instead of onto a hypervisor. I don’t have anything for this area this time around, but I’ll stay alert for articles to add next time. Servers/Hardware.
I have a few more links than normal this time around, although I didn’t find articles in a couple categories. Don’t worry—I’ll keep my eyes peeled and my RSS reader ready to pull in new articles in those categories for next time. Nick Schmidt talks about using GitOps with the NSX Advanced LoadBalancer.
I never found the root cause, but we did find a workaround; however, along the way, someone shared this article with me. Dan Lorenc’s article on policy and attestations does a great job of covering key concepts like signatures, attestations, and provenance. This is a great article on using jq with kubectl. Kudos to J.
Workloads are scheduled across these server/linecards using Valiant LoadBalancing (VLB). Of course, there are issues with packet-level loadbalancing and flow-level loadbalancing, so tradeoffs must be made one way or another. This article was originally posted on blog.scottlowe.org.
What about virtualized loadbalancers? This article was originally posted on blog.scottlowe.org. Think about it: existing protocols like OSPF and BGP (which run in software ) manipulate the forwarding rules in the data plane—does that make them SDN, too? What about NX-OS, JUNOS, or EOS? What about having APIs on switches?
Christopher Davis has an article discussing a recommended VPC subnet configuration. This is, of course, just one way of handling subnets within a VPC, but some of the principles outlined in Christopher’s article are definitely sound. This article is pretty high-level; I wish it had a bit more depth to it. Networking.
I hope that everyone had a wonderful holiday season, but now it’s time to jump back into the fray with a collection of technical articles from around the Internet. Eric Sloof mentions the NSX-T loadbalancing encyclopedia (found here ), which intends to be an authoritative resource to NSX-T loadbalancing configuration and management.
Thats to say it includes I/O virtualization, a converged network fabric (including virtual switches and loadbalancing - based on std. Good article, thanks. Its a "unified computing" environment (to borrow a term) - but has integrated with it all of the most popular higher-level management functions too. Ken Oestreich.
Welcome to Technology Short Take #25, my irregularly-published collection of links, articles, thoughts, and rants.

Here’s a fresh new collection of links and articles from the around the web to propel myself back into blogging. These two articles are interesting (to me) because they combine both network automation and Kubernetes. David Holder walks through removing unused loadbalancer IP allocations in NSX-T when used with PKS.
Russell Bryant has a couple great articles on OVN— how to test OVN’s “EZ Bake” release with DevStack as well as an article on implementing OpenStack security groups using OVN ACLs (which in turn leverage the integration between Open vSwitch and the Linux kernel’s conntrack module). Servers/Hardware. Cloud Computing/Cloud Management.
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. The title is a bit misleading; the article is really more about using different base images to optimize for size.
Nevertheless, I have persevered in order to deliver you this list of links and articles. Viktor van den Berg writes on deploying NSX loadbalancers with vRA. And he provides a GitHub repository with samples from the article.). I hope it proves useful! Networking. Larry Smith Jr.
