SDxCentral's latest research brief is aimed at providing enterprises contemplating purchasing SD-WAN solutions with a concrete five-step process and a set of core considerations critical to success.
Thao Nyugen works for Packet as director of hardware platforms. Coming from Facebook, he led the development and deployment of over 1 million Open Compute Project servers in the last eight years.
Traditional routing fails to differentiate between application and user requirements. SD-WAN is changing that with identity awareness.
The four new labs, alongside its existing lab in New York City, will rely on local partnerships to test and refine new 5G use cases.
Business moves fast in today’s digital landscape. Applications, services, and data are becoming more distributed, while threats are becoming more sophisticated. From data centers and the cloud to branches and the edge, IT teams are responsible for more environments than ever before, and the complexity is only increasing.
If your IT organization is under pressure to stay productive, increase agility, and help the business innovate, you know that expectations are high. You’re on the hook to:
Traditional, hardware-based approaches to networking and security can’t help you do all that. They’re inflexible and slow-moving; they require time-consuming manual intervention; they can’t connect and protect all the apps your business needs. That’s why it’s time to reinvent the network…in software.
Our digital, app-centric world can be daunting, but a programmable network was built to meet these changing demands and evolve right along with them. VMware NSX® delivers the foundation for a Continue reading
Historically and traditionally, academic supercomputing centers have been very open about the architecture and setup of their HPC systems, and it makes sense if you think about it. …

This is T-Mobile's second 5G equipment deal in two months. Ericsson is a long-time partner to T-Mobile and supplied some of the operator's LTE network equipment.
A few weeks back, we announced changes to extend the maintenance lifecycle for Docker Engine – Community (CE). As part of these changes, we’re having a beta testing period to deliver a higher-quality engine to the market.
We’d like to invite our community members to now participate in this beta testing by installing the beta package, kicking the tires, and submitting issues.
Docker Engine – Community version 18.09 adds these new features:
$ DOCKER_BUILDKIT=1 docker build .
You can also set the feature option in /etc/docker/daemon.json to enable BuildKit by default:
{"features":{"buildkit": true}}
$ docker -H ssh://[email protected]
Install Instructions:
Only install the beta package on a new system without previous versions of docker-ce installed.
$ curl -fsSL test.docker.com Continue reading
A robust edge deployment will be necessary for the carrier to deploy immersive services that will differentiate its 5G network from its current 4G LTE deployment.
Ok, you’ve just launched an Amazon EC2 instance (ie, a virtual machine) and you’re ready to login and get to work. Just once teeeensy problem though… you have no idea how to actually connect to the instance!
This post will walk through how to log into brand new Linux/BSD and Windows instances (the steps are slightly different for different OS families).
Regardless of the operating system, one requirement must be met: you must have connectivity into the Virtual Private Cloud (VPC) where you’ve launched the instance. This could be by giving the instance a public IP address so it’s reachable via the Internet or it could be via a VPN or other private connectivity into the VPC. The rest of the article assumes that this basic network connectivity is in place.
Linux/BSD instances are accessible via SSH. When the instance is launched, the Amazon Machine Image (AMI)–which acts like the template from which your instance is cloned–is setup to generate the necessary SSH host keys on first boot. You will have to provide the user key.
The Linux/FreeBSD AMIs used to launch the instance must support the generation of SSH host keys on first boot. The AMIs from Continue reading
I’d be lying if I said that since starting my new job at Amazon Web Services (AWS), I wasn’t looking forward to writing about all the new things I was going to learn. Obviously there’s the technology and services that make up the platform itself. But there’s also the architectural best practices, the design patterns, and answers to questions like “how does moving to the cloud improve my performance/security/reliability?”
Admittedly, I have a lot to learn. With my background being mostly in the network space for my entire career, stepping out of that and into a software and cloudy world means I’m ramping up on a lot of new skills and knowledge.
I believe I’m not the only one on this journey of learning and that, like me, there a lot of folks who are having to learn the basics of the cloud and specifically, AWS.
This has inspired me to start a new, open-ended series of blog posts that I’ve dubbed AWS ABC’s, targeted at people who have a lot of experiencing designing, operating, and architecting on-premesis systems but are now trying to up-skill by learning how to do the same in the cloud. These posts will Continue reading
We’re very excited to announce that Cloudflare Workers are now integrated into the Serverless framework as a serverless cloud provider! Serverless’ open source framework has become a must-have for many developers, and we want to make it as simple as possible to harness the power of Cloudflare’s distributed computing network.
Workers have become essential to the way people build applications on the web. The expressiveness of modern JavaScript combined with sub-30 second deploys to Cloudflare’s network of 152+ datacenters means that you can truly build your application into our global compute network. Up until this point, deploying Workers required doing all of your editing through our browser-based IDE or developing one’s own custom tooling on top of our API. But many developers have their own environments and are already familiar with the Serverless framework, so it seemed natural that we build first-class support for Workers into Serverless!
You can now define the entire structure and routing behavior of your Workers scripts in code and deploy them with ease using serverless deploy from your own development environment. Store configuration files in version control alongside your application code. And feel more confident testing your application with serverless invoke, a new way Continue reading
If there’s no BFD If you have two routers directly connected, like here: In this case, it is normal that one of them will remove the routes learned from the other if the other one goes down completely. It is because the link will go to down state and the routing protocol adjacency will disappear. If two routers are connected through an L2 device (switch) like down here: In this case, when one of them goes down, it will not take down the interface of the L3 neighbour (other router) because the switch will still work fine and it will
