Red Hat is updating its OpenShiftplatform with a series of capabilities that will provide more advanced networking and virtualization functionality for cloud-native deployments. The custom UDNs are being integrated into the open virtual networking (OVN) Kubernetes container networking interface (CNI). In particular, OpenShift 4.18
A little over a month ago I published a post on creating a Talos Linux cluster on AWS with Pulumi. Talos Linux is a re-thinking of your typical Linux distribution, custom-built for running Kubernetes. Talos Linux has no SSH access, no shell, and no console; instead, everything is managed via a gRPC API.
For example, the server virtualization value proposition is simple. You can save money if you consolidate your Windows & Linux workloads to fewer servers. Once server virtualization is in the door more of the operational advantages and efficiencies appear. Network virtualization allows for more powerful automation.
By adding free cloud training to our Community Membership, students have the opportunity to develop their Linux and cloud skills further. Each month, we will kick off our community content with a live study group, allowing members of the Linux Academy community to come together and share their insights in order to learn from one another.
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). Think Linux doesn’t have malware?
“My favorite parts about Linux Academy are the practical lab sessions and access to playground servers, this is just next level.” It provides a huge range of virtual machines suitable for general purpose and specialized on-demand compute tasks. First, you will create and configure an Application LoadBalancer.
This week, we’re talking all about serverless computing, what it is, why it’s relevant, and the release of a free course that can be enjoyed by everyone on the Linux Academy platform, including Community Edition account members. You have to launch the virtual servers, which means you need to: Choose an operating system. Now h old up.
Each cloud computing provider has “opinionated” ways of handling things such as loadbalancing, elastic scaling, service discovery, data access, and security to name just a few. Additionally, how one would deploy their application into these environments can vary greatly.
These articles are a bit long in the tooth, but CSS Corp has a useful series of articles on bundling various Linux distributions for use with OpenStack: bundling CentOS , bundling CentOS with VNC , bundling Debian , and bundling OpenSUSE. Virtualization. Both KVM and QEMU are needed for a full virtualization solution.
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. Virtualization. Only a true geek would be interested in this, but here’s some information on running OpenBSD in KVM on Linux.
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. Michael Kashin shares the journey of containerizing NVIDIA Cumulus Linux. Virtualization.
Linux Academy is the only way to get exam-like training for multiple Microsoft Azure certifications. Deploying and managing virtual machines. Create a LoadBalanced VM Scale Set in Azure. The post Azure Training Courses | New January Releases appeared first on Linux Academy Blog. Creating and managing alerts.
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.
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. IDF 2014: Virtualizing the Network to Enable SDI.
Here’s a handy list of deprecated Linux network commands and their replacements. Konstantin Ryabitsev has a series going on securing a SysAdmin Linux workstation. Part 1 covers how to choose a Linux distribution, and part 2 discusses some security tips for installing Linux on your SysAdmin workstation. Virtualization.
The rise of the disaggregated network operating system (NOS) marches on: this time, it’s Big Switch Networks announcing expanded hardware support in Open Network Linux (ONL) , upon which its own NOS is based. I use OTR with Adium on OS X, and OTR with Pidgin on my Fedora Linux laptop.). Virtualization. Servers/Hardware.

Michael Kashin shares the journey of containerizing NVIDIA Cumulus Linux.
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. Matt Oswalt takes readers though a fairly in-depth look at sockets and address binds in Linux. Virtualization.
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. Virtualization. Abdullah Abdullah shares some thoughts on design decisions regarding NSX VXLAN control plane replication modes. Servers/Hardware.
High speed low latency networks now allow us to add these nodes anywhere in a cloud infrastructure and configure them under existing loadbalancers. OpenStack is a proven Infrastructure as a Service solution that has the ability to scale virtual machines based on the metrics of existing nodes. Automated Kubernetes Deployments.
Vincent Bernat has a really in-depth article on IPv4 route lookup on Linux (and one on IPv6 route lookup as well). and their product (VirTool Network Analyzer) is aimed at providing some operational visibility into OpenStack virtual networks. Virtualization. Here’s hoping you find something useful! Networking.
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. Virtualization. Fortunately, the diagrams illustrate that there is something substantive behind the headline.
Via Ivan Pepelnjak, I was pointed to Jon Langemak’s in-depth discussion of working with Linux VRFs. The first is a post on Cilium and F5 loadbalancer integration , while the second discusses implementing Kubernetes network policies with Cilium and Linkerd. Virtualization. Networking. Career/Soft Skills.
Scott McCarty explains sVirt and how it’s used to isolate Linux containers. Check out these articles talking about IPVS-based in-cluster loadbalancing , CoreDNS , dynamic kubelet configuration , and resizing persistent volumes in Kubernetes. Virtualization. Servers/Hardware. Nothing this time around, sorry!
Open Virtual Network (OVN) is really ramping up and getting lots of attention, which I personally think is absolutely well-deserved. Linux network namespaces is a topic I’ve covered here before , but it’s always great to have multiple viewpoints and explanations of technologies and concepts to get a complete and comprehensive view.
If you’d like to play around with Cumulus Linux but don’t have a compatible hardware switch, Cumulus VX is the answer. This article listing 20 Linux server hardening tips contains some basic tips but is nevertheless a very good resource for someone looking for Linux security recommendations. Virtualization.
tech preview of virtual networks for Docker. The “gotcha” is that these software stacks haven’t been written yet, so the idea of repurposing hardware from switch to firewall to loadbalancer is still a bit of a unicorn. Virtualization. Never fear, this site has a walkthrough of the Socketplane.io Servers/Hardware.
OS X provides an SSH agent by default, but on Linux systems you will probably have to manually run an SSH agent and add the appropriate SSH key: eval `ssh-agent -s` ssh-add ~/.ssh/keyfile.pem. Visit the site for more information on virtualization, servers, storage, and other enterprise technologies. Linux CLI Docker OSS'
