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.

How do companies manage the security implications of working from home, in a country where remote work has generally been frowned on? Devo, a data analytics and security platform with headquarters in Madrid, helps companies get visibility into their networks — something that has become even more critical as more companies rely on virtual private network (VPNs) to security connect team members working from home.

With so many countries in lockdown and so many people working (and learning) from home, online usage has risen significantly but so far, the internet is holding up well.
Internet traffic is generally to 25% to 30% higher than usual, and what we do online is also changing. Internet usage often increases goes up in a typical month; for Akamai that’s usually 3% growth, in the last month it’s been 30%. In March 2019 their peak traffic was 82Tbps; this March it was 167Tbps and the sustained daily traffic rate is higher than last year’s peak for March. Internet exchanges in Amsterdam, Frankfurt and London saw 10-20% increases in traffic around March 9th, which the exchange in Milan had a 40% increase the day Italy was quarantined.
Disturbingly, attacks are up too: Akamai Cloudflare tracks varies by city; it’s only up 11% in Berlin and 22% in London between early January and late March (and 17% up for the UK as whole), but it’s grown by 40% in New York and 48% in San Francisco and Silicon Continue reading
There’s been quite a bit of fanfare around quantum computing during the last few years, with experts predicting that quantum computers will help fuel the growing computational demands of artificial intelligence, as well as forming the backbone of an unhackable internet. But beyond the hype is the reality that quantum computers are still some ways from being commercially viable, as researchers continue to resolve issues like accuracy, size and how to build a superconducting electrical oscillators that are used in some quantum chips need to be cooled down to near-absolute zero temperatures, otherwise the problem of Quantum Device Lab at study co-author quantum entanglement, two particles become linked in a way so that whatever happens to one particle, it also immediately occurs to the other, no matter the distance.
Having proven that a cryogenically based, long-distance quantum network is indeed possible, the team is now working to construct a 30-meter (98.4-foot) quantum link.

Dragonfly, a peer-to-peer image and file-sharing technology developed by Cloud Native Computing Foundation. The software provides a way to quickly distribute images across large cloud native deployments, eliminating the dependency on a single registry to distribute all the copies of an image.
“Dragonfly is one of the backbone technologies for container platforms within Alibaba’s ecosystem, supporting billions of application deliveries each year, and in use by many enterprise customers around the world,” said Dragonfly in 2015, originally to ease file distribution. By 2017, when it was adopted to share containers within Kubernetes environments, it was being used by the Chinese cloud service to share 3.4PB each month. It was originally accepted into the OCI (Open Container Initiative). It can work with CNCF’s Prometheus and display them on a Helm can be used to install Dragonfly within a Kubernetes cluster.
Project maintainers come from Alibaba, ByteDance, eBay, and Meitu. Overall it has 67 contributors from 21 organizations. It has been downloaded over 100,000 times from Docker Hub and has massed 6,000 GitHub stars.

It is too early to determine to what extent our lives will change in the future once the Coronavirus pandemic has run its full course. However, in the software industry, some possible outcomes are beginning to emerge, including consolidation and the potential for great changes to take place — both good and bad.
As a harbinger of what may come, SaltStack, a leading automation network infrastructure provider, evoked historical examples of pandemics and plagues in the past. He discussed what changes they wrought on ancient Egypt, the Roman Empire and the Renaissance era, while drawing parallels with the software industry. Patch also shared with The New Stack in this Q&A how software engineers’ lives have hardly changed, the folly of forcing workers to come to the office when they really do not need to and his observations of network infrastructure saturation in the wake of the
Istio has emerged as one of the most frequently utilized service mesh technologies for securing and controlling network traffic within containers and Kubernetes. Its powerful feature set makes it instrumental in solving a number of real issues users regularly encounter when running microservices. Following the standard three-month period since the release of Istio 1.4, Istio 1.5 introduces an impressive number of improvements that increase automation and provide tooling to help further operationalize the platform.
With major architectural changes and several API updates under the hood, Istio 1.5 provides new capabilities that improve the user experience and functionality of the platform. The following highlights will help organizations optimize Istio for configuration management, architecture support, and overall performance.

Software intelligence company Alois Reitbauer, vice president and chief technology strategist for Dynatrace, shared his observations about what the company is seeing.
While Reitbauer usually splits his time between living and working in the United States and Europe, Reitbauer spoke with The New Stack from his remote-location home in Austria.
What traffic changes are your customers seeing due to the effects of the COVID-19 pandemic?
It’s definitely important to know we’re experiencing a perfect storm scenario right now. We all need to be on the same page for what’s going to happen.
We have certainly ramped up our monitoring of networks recently. So the way you can describe the situation for many websites now is it’s just like Black Friday, where all people go really wild on a certain number of sites. The only difference with Black Friday- or Super Bowl-like surges in traffic compared to the saturation COVID-19 might cause is that nobody knows when it’s happening.

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

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
The newest version of the open source version 1.5, comes with a fresh installer to simplify the deployment process, along with a new extension model, based on WebAssembly (WASM), to help proxy servers better filter traffic.

When user experience is increasingly synonymous with speed and reliability, new traffic management sub-teams are appearing at elite digital enterprises.
In this episode of The New Stack Makers podcast, we talk to NS1, the networking automation company or, as he calls it, “the system of record for many, many of the key domains and the applications on the internet today.”

He says that each of us interacts with NS1 dozens of times a day, like when we are connecting on LinkedIn or sharing files on DropBox.
NS1 sits at the base of this new traffic management stack, steering that traffic across our increasingly complex and distributed systems. This stack also includes content networking delivery networks (CDN), load-balancing tooling, edge networking footprints, service meshes, and software for service discovery and egress optimization. This new role isn’t just about measuring if traffic is working correctly, but really understanding both your users and systems Continue reading
Cyberattackers are now increasingly targeting APIs, especially in the financial sector, according to content delivery network Akamai’s between 15% and 30% of all web traffic. The Cambridge, Massachusetts-based company hAndy Ellis neatly summarized the resultsemail to VentureBeat, Akamai explained some of the advantages of automation: criminals “use bots and tools that allow threading, or multiple simultaneous connections, to attempt multiple logins at once.” And by targeting APIs, “they hope to avoid some front-end defenses and speed up their validation times.” A recent Franck V. on
