Take a Network Break! We discuss Nvidia clearing a major hurdle to its Mellanox acquisition, GitHub changes its pricing, the startup Alkira tackles multi-cloud networking, and more tech news analysis. Our guest commentator is Stephen Foskett, founder of Tech Field Day and GestaltIT.
The great
divide: The continuing digital divide in the
U.S. is hurting people as they try to shop, attend school, and work during the
coronavirus pandemic lockdown, The Guardian says. Broadband Now
estimates that 42 million U.S. residents don’t have Internet access, and M-Lab
says that the majority of residents in 62 percent of the counties across the
U.S. don’t have adequate broadband speeds.
The struggle is real: Meanwhile, students in rural Alabama are struggling to complete their schoolwork because a lack of Internet access, according to an Associated Press story at Enewscourier.com. In nine Alabama counties, less than 30 percent of the population has access. “We don’t want to leave 20 to 30 percent of our population behind just because of where they live,” said John Heard, school superintendent in Perry County.
The good news: Even with many people across the world working from home or attending school from home, the Internet is holding up, ZDNet reports. Fastly, an edge cloud computing provider, found that in the hard-hit New York and New Jersey area, Internet traffic jumped by nearly 45 percent in March, but download speeds decreased by less than 6 percent. In California, traffic Continue reading
It's a network jungle these days with predators relentlessly searching for ways to infiltrate corporate resources. IT leaders are responding with a variety of different microsegmentation approaches, all designed to isolate workloads from each other and prevent unauthorized lateral movements. We asked three enterprises to share why they deployed microsegmentation technology in their networks and how it's working. Here are their stories.Distributed firewalls via VMware NSX
Todd Pugh, CIO at food products manufacturer SugarCreek, manages a fully virtualized private data center. Like his counterparts at organizations worldwide, his goal is simple: to frustrate and deter network attackers. "Above all, we protect our databases," he says. "We do anything and everything to keep uninvited guests out of our databases."To read this article in full, please click here(Insider Story)

There was quite a considerable amount of the feedbacks on the previous post about the data centre network visualisation with graphs. Originally we planned to cover the topology generation today. However, we changed the plan to improve the math model of our graph to make it more flexible and useful from modelling perspective.

Network automation training – boost your career
To be able to understand and, more important, to create such a solutions, you need to have a holistic knowledge about the network automation. Come to our network automation training to get this knowledge and skills.
At this training we teach you all the necessary concepts such as YANG data modelling, working with JSON/YAML/XML data formats, Linux administration basics, programming in Bash/Ansible/Python for multiple network operation systems including Cisco IOS XR, Nokia SR OS, Arista EOS and Cumulus Linux. All the most useful things such as NETCONF, REST API, OpenConfig and many Continue reading

Recently, we had a customer issue where a production GKE cluster was deleted accidentally which caused some outage till the cluster recovery was completed. Recovering the cluster was not straightforward as the customer did not have any automated backup/restore mechanism and also the presence of stateful workloads complicated this further. I started looking at some … Continue reading Kubernetes DR→
First of all, not everyone will agree that you even need certifications. That’s another discussion and I think there are not many reasons to avoid them entirely, but let’s assume that you already have certifications, when do you give up on them?
That is going to be a choice each person has to make, and it will depend on a number of factors, I think. Here are some that immediately come to mind:
How do you learn?
Current role
Bonus models
Future role
Number of years in the industry
Body of work
Are you well known in the industry?
What’s your method for learning a new skill? People use certifications differently but for me it’s about a guided learning path. I know roughly what to study to become decently skilled at a topic. For example, when I wanted to learn more about AWS and their networking, I decided to study for the AWS Solutions Architect Associate. For me, it’s motivating to Continue reading
Git is great (once you get beyond the basic recipes), and I love my new blog setup that allows me to keep track of all the changes I make with Git.
However, there’s a slight gotcha if you use Git with Markdown: whenever you change something, the whole line (and using tools like IA Writer a whole paragraph is a single line) is marked as changed, for example:
The Internet has been vital to our response to the COVID-19 crisis: enabling researchers to communicate with the rest of the world, connecting resources with people who need them, and sharing data about the spread.
It’s been amazing to see some of the projects people have stood up on Cloudflare Workers to assist during this crisis. Workers allows you to get set up in minutes, it’s fast and scalable out of the box, and there’s no infrastructure to maintain or scale, which is great if you want to create a project quickly.
To support critical web projects that help in the fight against the COVID-19 pandemic, we’re giving free access to our Cloudflare Workers compute platform through Project Galileo. We believe sites, apps, APIs, and tools that can help people with COVID-19 are exactly the type of critically important projects that Project Galileo was designed to support.
Free Cloudflare Workers
One of the earliest impacts of the COVID-19 crisis was the switch that many organizations made to a fully remote model. As that happened, and we realized that many organization’s VPNs were not up to the task of scaling to support this increased load, Cloudflare made Cloudflare for Continue reading
Maybe it’s time to build our own network monitoring systems from open-source components instead of paying vendors big bucks for slick PowerPoint slides.
As the coronavirus spreads, public and private companies as well as government entities are requiring employees to work from home, putting unforeseen strain on all manner of networking technologies and causing bandwidth and security concerns.

Welcome to The New Stack Context, a podcast where we discuss the latest news and perspectives in the world of cloud native computing. For this week’s episode, we spoke with The New Stack correspondent Jennifer Riggins about all of the reporting she and others on the TNS team have been doing recently on the effects that the COVID-19 global pandemic is having on the tech industry.
TNS editorial and marketing director Libby Clark hosted this episode, alongside founder and TNS publisher Alex Williams and TNS managing editor Joab Jackson.

For this episode, we wanted to look at and not only discuss the changing patterns in network traffic that the global COVID-19 pandemic has wrought, due to factors such as people staying at home and working from home, and the sudden acceleration of e-learning. As Riggins writes in a recent post:
For a lot of tech and infrastructure teams, they not only are going through the stress of the collective trauma we’re sharing in, but they are struggling to keep up with ever-scaling, extreme strains on their systems. Simply put, Continue reading
If you deal with Kubernetes, you know that storage is one of the core building blocks of the cluster infrastructure. It is as important as the compute building block delivered by the worker nodes. Since the power of the cluster is always measured in terms of the number of worker nodes and their configuration, storage doesn’t get its share of attention.
Imagine this: you configured a powerful bare-metal cluster and want to run a highly available and mission-critical workload on it. Without a solid storage engine, your cluster is only good for running stateless and ephemeral workloads that don’t need persistence. But any enterprise application is a combination of both — stateless and stateful services. You wouldn’t be able to justify the investment made in the brand new Kubernetes cluster if you are unable to run end-to-end applications on it.
When you install the open source, up-steam Kubernetes distribution, it doesn’t come with a high-performance storage engine. Unlike managed Kubernetes services in the public cloud that come with default storage classes mapped to their respective block storage services, your cluster doesn’t have any storage class.
A persistent volume is to storage what a node is to compute.
Just like the Continue reading
