Bridge has matured to the point where customers can think of it as a digital operatingsystem that can be personalized, if you will, for each business to integrate our services, manage their data, and gather insights or patterns they need to operate at a highly efficient way,” Shagoury said. “A
This is the industry’s first universal kernel bypass (UKB) solution which includes three techniques for kernel bypass: a POSIX (Portable OperatingSystem Interface) sockets-based API (Application Program Interface), TCP (Transmission Control Protocol) Direct and DPDK (Data Plane Development Kit). The SFN8722 has 8 lanes of PCle 3.1

Flexibility is one of the key principles of Amazon Web Services - developers can select any programming language and software package, any operatingsystem, any middleware and any database to build systems and applications that meet their requirements. Driving Storage Costs Down for AWS Customers. Comments ().
OperatingSystems/Applications. I found this article on imperative vs. declarative system configuration is quite helpful in understanding Puppet’s declarative model. QEMU, on the other hand, is needed to emulate everything else that a VM needs: networking, storage, USB, keyboard, mouse, etc. Apparently, “Mt.
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. OperatingSystems/Applications. Is Cisco’s Insieme effort producing a storage product? storage enhancements. It starts here.
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!
s announcement of Amazon RDS for Microsoft SQL Server and.NET support for AWS Elastic Beanstalk marks another important step in our commitment to increase the flexibility for AWS customers to use the choice of operatingsystem, programming language, development tools and database software that meet their application requirements.
Here’s a quick look at using Envoy as a loadbalancer in Kubernetes. It’s a good starting point for thinking about operating your own active-active architecture. OperatingSystems/Applications. I hope this collection of links has something useful for you! Networking.
OperatingSystems/Applications. Here’s a Windows-centric walkthrough to using Nginx to loadbalance across a Docker Swarm cluster. Brian Ragazzi shares a lesson learned the hard way regarding VVols: place the VSM/VASA on a non-VVol storage location. A command-line client for Twitter ? Yes, please! (I
The rise of the disaggregated network operatingsystem (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. OperatingSystems/Applications. Cormac Hogan has a brief update on storage options for containers on VMware.
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. OperatingSystems/Applications. Servers/Hardware. Nothing this time (sorry!). Ben Evans has a four-part series (so far) on vSAN.
OperatingSystems/Applications. Rudi Martinsen has an article on changing the Avi loadbalancer license tier (this is in the context of using it with vSphere with Tanzu). This article provides some great “behind the scenes” information on AWS Lambda. This is a great article on using jq with kubectl.
Eric Sloof mentions the NSX-T loadbalancing encyclopedia (found here ), which intends to be an authoritative resource to NSX-T loadbalancing configuration and management. OperatingSystems/Applications. Here’s hoping that I found something useful for you! Networking. This is kind of cool.
NFV is intended to address the problem caused by having to route/direct traffic from various sources through physical appliances designed to provide services like content filtering, security, content delivery/acceleration, and loadbalancing. It is hardware switch independent. This article was originally posted on blog.scottlowe.org.
OperatingSystems/Applications. The series starts with part 0 (preparation), and continues with part 1 (mostly about rpm-ostree ), part 2 (container storage), part 3 (rebase, upgrade, and rollback), part 4 (package layering and experimental features), and part 5 (containerized and non-containerized applications). RIP Solaris.
Kamal Kyrala discusses a method for accessing Kubernetes Services without Ingress, NodePort, or loadbalancers. AWS adds local NVMe storage to the M5 instance family; more details here. What I found interesting is that the local NVMe storage is also hardware encrypted. OperatingSystems/Applications.
Check out these articles talking about IPVS-based in-cluster loadbalancing , CoreDNS , dynamic kubelet configuration , and resizing persistent volumes in Kubernetes. OperatingSystems/Applications. Nathaniel Avery shares a tip on saving some money by using the right servers on Azure. Virtualization.
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. OperatingSystems/Applications. Servers/Hardware. Cabling is hardware, right? Virtualization.
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. OperatingSystems/Applications. Unfortunately, this appears to be GKE-specific. Servers/Hardware.
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. OperatingSystems/Applications. Many of these concepts had direct impacts on the design of Envoy. Good stuff!
March Study Group Course: Linux OperatingSystem Fundamentals – Have you heard of Linux, but don’t really know anything about it? Students will get hands-on training by installing and configuring containers and thoughtfully selecting a persistent storage strategy. Stay tuned to the Linux Academy blog for further details.
Here’s a quick look at using Envoy as a loadbalancer in Kubernetes. It’s a good starting point for thinking about operating your own active-active architecture. OperatingSystems/Applications. I hope this collection of links has something useful for you! Networking.
Viktor van den Berg writes on deploying NSX loadbalancers with vRA. OperatingSystems/Applications. IPVLAN is a low-latency means of providing IP connectivity to containers. VPCs, or Virtual Private Clouds, are Amazon’s software-defined networking mechanism for workloads running on AWS.).
David Holder walks through removing unused loadbalancer IP allocations in NSX-T when used with PKS. OperatingSystems/Applications. Cormac Hogan has recently published three good articles on storage in Kubernetes (the articles are all part of a larger “Kubernetes Storage on vSphere” series).
Bernd Malmqvist talks about Avi Networks’ software-defined loadbalancing solution, including providing an overview of how to use Vagrant to test it yourself. OperatingSystems/Applications. It looks like there will be a follow-up to this article as well, so you may want to check back on Ajay’s site.
OperatingSystems/Applications. Rudi Martinsen has an article on changing the Avi loadbalancer license tier (this is in the context of using it with vSphere with Tanzu). This article provides some great “behind the scenes” information on AWS Lambda. This is a great article on using jq with kubectl.
This time around, the content is a bit heavier on cloud management and applications/operatingsystems, but still lots of good content all the way around (I hope, anyway). OperatingSystems/Applications. Networking. Matt Oswalt recently wrapped up his 3-part “DevOps for Networking” series. Servers/Hardware.
OperatingSystems/Applications. Lew Goettner has a pretty hefty post on CoreOS and Docker on AWS that includes information on CoreOS, user data and cloud-init, AWS and Elastic LoadBalancers (ELBs), Fleet, Registrator, Nginx, Confd, and Jenkins. In case you missed it, Docker 1.9 It’s a whirlwind of technologies.

This is an older post on OpenStack availability zones and host aggregates , but useful nevertheless (for me, at least). Want to run Docker Swarm on Azure? The recent release of CentOS 7.2
Things like what operatingsystem an application used no longer mattered – you could mix and match to your heart’s content. Kotsovinos points out that a VM is really a collection of interconnected physical subsystems : server, storage, and network. No longer will the storage team be able to just focus on storage issues.
