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

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

Introducing Quicksilver: Configuration Distribution at Internet Scale

Introducing Quicksilver: Configuration Distribution at Internet Scale

Cloudflare’s network processes more than fourteen million HTTP requests per second at peak for Internet users around the world. We spend a lot of time thinking about the tools we use to make those requests faster and more secure, but a secret-sauce which makes all of this possible is how we distribute configuration globally. Every time a user makes a change to their DNS, adds a Worker, or makes any of hundreds of other changes to their configuration, we distribute that change to 200 cities in 90 countries where we operate hardware. And we do that within seconds. The system that does this needs to not only be fast, but also impeccably reliable: more than 26 million Internet properties are depending on it. It also has had to scale dramatically as Cloudflare has grown over the past decade.

Historically, we built this system on top of the Kyoto Tycoon (KT) datastore. In the early days, it served us incredibly well. We contributed support for encrypted replication and wrote a foreign data wrapper for PostgreSQL. However, what worked for the first 25 cities was starting to show its age as we passed 100. In the summer of 2015 we decided to Continue reading

5 metrics you need to know about your backup and recovery system

Finding out whether backup and recovery systems work well is more complicated than just knowing how long backups and restores take; agreeing to a core set of essential metrics is the key to properly judging your system to determine if it succeeds or needs a redesign.Here are five metrics every enterprise should gather in order to insure that their systems meet the needs of the business.Storage capacity and usage Let's start with a very basic metric: Does your backup system have enough storage capacity to meet your current and future backup and recovery needs? Whether you are talking a tape library or a storage array, your storage system has a finite amount of capacity, and you need to monitor what that capacity is and what percentage of it you're using over time.To read this article in full, please click here

Webinars in April 2020

With webinars being the only way to deliver training content these days, we’ll run one every week in April 2020:

  • Starting on April 2nd I’ll talk about one of my favorite topics: switching, bridging and routing, covering almost everything ever invented from virtual circuits and source route bridging to so-called routing at layer-2 and IP forwarding based on host routes;

  • I was planning to update the Introduction to Containers and Docker material for ages… but then had to move the December 2019 workshop to March 2020, only to cancel it a week before the coronavirus exploded for real in Switzerland. I hope I’ll manage to deliver the online version on April 9th ;)

  • Dinesh Dutt is back on April 16th with an update of Network Automation Tools webinar, in which he’ll cover (among other things) the new network automation tools launched since we did the original webinar in 2016.

  • On April 23rd Pete Lumbis plans to dive as deep into the intricacies of switching ASICs as he can without violating an NDA ;)
