Lim explained that BGP enables dynamically exposing cluster-scoped network entities into a providers network, as well as programming BGP-learned routes from the providers network into OVN-Kubernetes. This is particularly useful for integration with third-party loadbalancers needing direct access to backend OpenShift pods or VMs, she said.
Talos Linux is a Linux distribution purpose-built for running Kubernetes. The Talos web site describes Talos Linux as “secure, immutable, and minimal.” In this post, I’ll share how to use Pulumi to automate the creation of a Talos Linux cluster on AWS.
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.
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.
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. Configure auto-scaling with loadbalancers. Serverless Computing: What is it? Now h old up.
Flexibility is one of the key principles of Amazon Web Services - developers can select any programming language and software package, any operating system, any middleware and any database to build systems and applications that meet their requirements. AWS Elastic Beanstalk: A Quick and Simple Way into the Cloud. Comments ().
Graf starts by talking about how BPF (specifically, extended BPF or eBPF) can be used to rethink how the Linux kernel handles network traffic. BPF can reject unauthorized connections before the Linux kernel even starts building TCP packets and moving them among various components within the kernel. What is XDP?
Linux Academy is the only way to get exam-like training for multiple Microsoft Azure certifications. Create a LoadBalanced VM Scale Set in Azure. The post Azure Training Courses | New January Releases appeared first on Linux Academy Blog. Azure Storage Accounts: Configuration and Security. Configuring Azure Backups.
Matt Oswalt has a great post on the need for networking professionals to learn basic scripting skills—something he (rightfully) distinguishes from programming as a full-time occupation. Here’s a handy list of deprecated Linux network commands and their replacements. Networking. Cloud Computing/Cloud Management.
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. Servers/Hardware.
By using the Kubernetes Metrics Server or metrics from tools such as Prometheus, a cluster may respond to resource demands when pre-programmed thresholds are surpassed. High speed low latency networks now allow us to add these nodes anywhere in a cloud infrastructure and configure them under existing loadbalancers.
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. Programming. Networking.
If you’d like to play around with Cumulus Linux but don’t have a compatible hardware switch, Cumulus VX is the answer. It says the the JET (Juniper Extension Toolkit) uses “open application programming interfaces”, but fails to provide any specifics. Is this “open-washing”, or is there actually some meat to this? Virtualization.
Over 800+ participants participated in the private beta and the early access program for DTR—this included companies like GE, Capital One, Disney, and others. As the panel wraps up, Johnston keeps Russinovich on stage, and transitions into a discussion about the use of both Linux and Windows for Docker containers.
Hammond: So I kind of got a little bit more inquisitive and a lot more curious and wanting to learn and understand more about the technology in front of the computers, the programs that I would use on a day to day basis. And I would just wonder like how does that work. Why does it work the way that it does.

Golub gives a “shout out” to the technologies underpinning modern Linux containers (namespaces, cgroups, etc., After Aimonetti finishes, Hykes takes the stage again to review the progress made on Docker for Mac/Windows, and to open the beta program up to any and all participants. Enhancing portability. Extending community.
