Service Mesh Adds Security, Observability and Traffic Control to Kubernetes

This week and next, The News Stack will be running a series of posts on the value that a service mesh brings to Kubernetes deployments. Here is the first installment. Check back often for more updates. As we explore all the tools and additional infrastructure layers that complement Kubernetes, it’s important to remember: None of this is to imply that Kubernetes is lacking. Kubernetes is a powerful tool to dramatically simplify running containerized applications, but there are many things that it was simply never intended to do. Service meshes are an example of a complementary piece of the infrastructure, handling things that Kubernetes can not and was never intended to do.  “The Kubernetes team at Google and the Istio team at Google were neighbors and were discussing these things,” explained Tetrate and one of the original creators of the William Morgan, CEO of Linkerd. “It’s because Kubernetes is really good but it has a well-defined scope.” A service mesh is Continue reading

Betting On Extreme Co-Design For Compute Chips

Whether or not the coronavirus pandemic causes the Great Recession II or the Great Depression II, we are without a doubt entering an era when IT industry is going to need lower prices, better performance, and better thermal profiles for their compute engines than they have ever required before. …

Ops by Pull Request: An Ansible GitOps Story

In a previous blog post I introduced Automation Webhooks and their uses with Infrastructure-as-Code (IaC) workflows and Red Hat Ansible Automation Platform. In this blog post, I’ll cover how those features can be applied to creating GitOps pipelines, a particular workflow gaining popularity in the cloud-native space, using Ansible and the unique benefits utilizing Ansible provides. 

 

What is GitOps?

Like so many terms that evolve and emerge from the insights and practices of what came before it, finding a definitive meaning to the term “GitOps” is a bit elusive. 

GitOps is a workflow whose conceptual roots started with Martin Fowler’s comprehensive Continuous Integration overview in 2006 and descends from Site Reliability Engineering (SRE), DevOps culture and Infrastructure as Code (IaC) patterns. What makes it unique is that GitOps is a prescriptive style of Infrastructure as Code based on the experience and wisdom of what works in deploying and managing large, sophisticated, distributed and cloud-native systems. So you can implement git-centric workflows where you treat infrastructure like it is code, but it doesn’t mean it’s GitOps.

The term GitOps was coined by Alexis Richardson, CEO and Founder of Weaveworks, so a lot of how I’m going to define Continue reading

What Has COVID-19 Taught Us About Information Networks?

Niraj Tolia Niraj Tolia is the CEO and co-founder at Kasten and is interested in all things Kubernetes. He has played multiple roles in the past, including the Senior Director of Engineering for Dell EMC's CloudBoost family of products and the VP of Engineering and Chief Architect at Maginatics (acquired by EMC). Niraj received his Ph.D., MS, and BS in Computer Engineering from Carnegie Mellon University. COVID-19 has been the most disruptive event in modern history, right up there with 9/11. But unlike a terrorist’s attack, this one has no geographic, ideological, or political boundaries. It’s been an equal opportunity pestilence, and there’s no way to downplay its impact. However, it may be comforting to know that if it had occurred as recently as 30 or 40 years ago, a coronavirus outbreak would have been a far greater disaster. That’s because, during the intervening decades, a robust global communication network infrastructure has emerged. Today, a significant portion of the world’s commerce, administrative, and productive work is routinely conducted through that network’s digital conduits, clouds, server farms, data centers, and privately owned user devices. As a result, even with a massive workforce quarantine in place, a lot of work Continue reading

In New York City, Building a Network While Social Distancing

NYC Mesh connects people to “critical Internet lifeline” during COVID-19 pandemic

As COVID-19 spreads across the globe, cities are slowing to a halt and millions of people are self-isolating to help slow the spread of the virus.

The Internet has never been more important. It is a critical for up-to-date health information, a necessity for students to continue their education while at home and for their parent to continue working, enables access to government programs and supports like unemployment insurance, and can help alleviate the effects of social isolation.

Yet, in New York City alone, 1.5 million people don’t have access from their homes or mobile devices, largely due to high costs of connectivity.

A group of volunteers is working around the clock to change that, one antenna at a time.

NYC Mesh, a community network supported by the Internet Society, kicked into high gear earlier this month in advance of the pandemic, getting as many people connected as possible while it was still safe to do so, prioritizing those with no other Internet access. The ramp up –going from a couple of installs a week to one or more a day – was “a mad rush of Continue reading

The Week in Internet News: U.S. Senator Fears Attacks on Connectivity

Networked virus: U.S. Senator Mark Warner has raised concerns about cyberattacks targeting Internet connectivity while many people are working from home due to the COVID-19 outbreak, The Hill reports. Warner, vice chairman on the Senate Intelligence Committee, wrote letters to network device vendors asking that they pump up the security of their products.

Sharing the WiFi: The U.S. Federal Communications Commission will allow schools and libraries to share their WiFi connections with the surrounding communities during the coronavirus pandemic, a change in the normal FCC policy about their WiFi networks, KRCRTV.com reports. Schools and libraries can set their own WiFi-sharing policies, the FCC said. Meanwhile, some libraries want to extend their WiFi networks using bookmobiles, Vice.com says. It’s unclear if FCC rules allow this expansion of service, however.

Tracking you and the virus: Some countries are tracking the coronavirus outbreak by tracking residents’ mobile phones, Science Magazine says. However, tracking phones also raises privacy concerns. “We don’t live in a culture of public trust when it comes to data,” says David Leslie, an ethicist at the Alan Turing Institute. “We live in this age that has been called the age of surveillance capitalism, where … our Continue reading

Multi-Platform Docker Builds

This is a guest post from Docker Captain Adrian Mouat who is Chief Scientist at Container Solutions, a cloud-native consultancy and Kubernetes Certified Service Provider. Adrian is the author of “Using Docker,” published by O’Reilly Media. He is currently developing Trow, a container image registry designed to securely manage the flow of images in a Kubernetes cluster. Adrian is a regular conference speaker and trainer and he has spoken at several events including KubeCon EU, DockerCon, CraftConf, TuringFest and GOTO Amsterdam.

Docker images have become a standard tool for testing and deploying new and third-party software. I’m the main developer of the open source Trow registry and Docker images are the primary way people install the tool. If I didn’t provide images, others would end up rolling their own which would duplicate work and create maintenance issues.

By default, the Docker images we create run on the linux/amd64 platform. This works for the majority of development machines and cloud providers but leaves users of other platforms out in the cold. This is a substantial audience – think of home-labs built from Raspberry Pis, companies producing IoT devices, organisations running on IBM mainframes and clouds utilising low-power arm64 chips. Users of Continue reading
