Doubling the intern class – and making it all virtual

Earlier this month, we announced our plans to relaunch our intern hiring and double our intern class this summer to support more students who may have lost their internships due to COVID-19. You can find that story here. We’ve had interns joining us over the last few summers - students were able to find their way to us by applying to full-time roles and sometimes through Twitter. But, it wasn’t until last summer, in 2019, when we officially had our first official Summer Internship Program. And this year, we are doubling down.

Why do we invest in interns?

We have found interns to be invaluable. Not only do they bring an electrifying new energy over the summer, but they also come with their curiosity to help solve problems, contribute to major projects, and bring refreshing perspectives to the company.

1. Ship projects: Our interns are matched with a team and work on real and meaningful projects. They are expected to ramp up, contribute like other members of the team and ship by the end of their internship.
2. Hire strong talent: The internship is the “ultimate interview” that allows us to better assess new grad talent. The 12 weeks they spend with Continue reading

NS1 Shows How DNS Technology Can Speed VPN Connections

The need for faster and more reliable VPN connections has certainly spiked recently in the wake of the COVID-19 pandemic and the massive shift of workers away from office hubs to home locations. For developers who must rely on VPNs for data transfers, the act of loading code on git and other more mundane tasks can obviously take much longer depending on network saturation from remote locations. Productivity is obviously lost, as well as time, which is in short supply for so many these days. Managed DNS support for VPNs can help to boost both network data transfer rates and robustness for VPNs, as well as other network infrastructure for any user, in addition to developers working remotely. To that end, DNS solutions provider Terry Bernstein, NS1 director of product management, said. The end result is improved VPN connectivity, which through load-balancing and steering connections at the DNS layer, are connected to the best performing endpoint. NS1’s DNS Continue reading

Tizona – Cli for Cloud Music

This is not a Network technology related post

https://tizonia.org/ – Opensource Project

In their own words ‘The most powerful cloud music player for the Linux terminal, with support for Spotify (Premium), Google Play Music (free and paid tiers), SoundCloud, YouTube, TuneIn radios, Plex servers and Chromecast devices.’

• 

What this has to do with this Post:

I have just implemented in an old Raspberry Pi which I was about to throw away. Secondly, it’s a passive project from at least 4 years to play cloud music on Linux CLI.

Why this obsession?

Ever think about music play all day but a very very low volume, am that kind of person. I don’t really listen to it very particularly all the times, but some music lingering in low volumes [Am speaking about extremely low volumes] will always help.

Why not use your LAPTOP ?

The very point of spreading it accross the home and not having to deal with GUI interfaces. Its much better for me not to have control as well, I just skip the tracks and will never be able to listen to new tracks.

Secondly, I dont want to spend a lot of money on crazy hardware with Continue reading

When EVPN EBGP Session between Loopbacks Makes Sense

One of the attendees of our Building Next-Generation Data Center online course submitted a picture-perfect solution to scalable layer-2 fabric design challenge:

• VXLAN/EVPN based data center fabric;
• IGP within the fabric;
• EBGP with the WAN edge routers because they’re run by a totally different team and they want to have a policy enforcement point between the two;
• EVPN over IBGP within the fabric;
• EVPN over EBGP between the fabric and WAN edge routers.

The only seemingly weird decision he made: he decided to run the EVPN EBGP session between loopback interfaces of core switches (used as BGP route reflectors) and WAN edge routers.

Why I Have Almost Quit Podcasts

Fear Of Missing Out

People that know me know that I like to stay up to date on what’s going on in the industry, new technologies, and so on. Mostly this is because I have a passion for technology and for learning. However, there is almost certainly a part of me that also, as many people do, has the fear of missing out (FOMO). That is, you are afraid to get left behind so you keep sipping from the fire hose constantly, because you believe everyone else is doing the same.

So Much Content!

There are many many fine podcasts out there. I used to listen to Packet Pushers, Software Gone Wild, Talk Python to Me, Clear to Send, and many more. These shows are extremely good at producing content consistently. Unfortunately, that means that you have maybe 4-5h of content to consume each week. That’s too much for me.

It’s Not You, It’s Me

I’m a very analytical person. Both by nature, and in my job role as an Architect. My brain is constantly analyzing, thinking, trying to solve problems. This makes me very efficient, but it also adds stress, and can make it difficult to wind down. As Continue reading

Deploying to Kubernetes: The GitOps Way

Kubernetes adoption comes with a lot of challenges. One of them is consistently deploying applications to the platform. GitOps is a strategy which solves this problem and solves it at scale. In this blog, we will share how to leverage TravisCI and ArgoCD to design a highly scalable production-ready CI/CD workflow. 

Deployment Workflow

GitOps follows one simple principle “Git is the Source of Truth”. The entire pipeline can be divided into two broad categories. (1) Continuous Integration, where we enable our developers to develop new features, test the code and merge it into a master. (2) Continuous Delivery, where we release new versions of the code for our customers.

Repo Structure

The application and the Kubernetes manifests/helm chart both reside in a git repository. The application source code’s git repo consists of various branches. Following the same principle, we also keep the helm charts for our microservices in a git repo itself. For the sake of this blog we will assume that each source code repository will have at least three (3) branches.

1. Dev Branch: This gets deployed to the Dev Kubernetes Environment
2. Staging Branch: This gets deployed to the Staging Kubernetes Environment
3. Master Branch Continue reading

Kids Need Encryption Too

With most of the world on lockdown, children are likely spending more time than ever online. Between virtual classrooms and keeping up with friends on social media, many kids are depending on the Internet to maintain a semblance of normal life amidst the global health crisis.

While parents may worry about how this might affect their children’s well-being, experts have warned that the surge in screen time could also expose kids to safety risks online more often.

In Asia-Pacific, a recent UNICEF report found that 32% of children between 10 to 17 years old in Bangladesh have faced cyberbullying, violence, and harassment online. Meanwhile, a McAfee study in India found that 70% of youngsters have posted their personal details on the Internet, making them an easy target for cybercriminals.

Earlier this month, the Internet Society ran a short webinar, Kids, the Internet and COVID-19, to show parents how they can protect their kids’ privacy and security online through encryption.

Encryption is a way of ‘scrambling’ information to make it unreadable to malicious actors who might want to access it, and works much like the codes that we used as children to send secret messages to each other – but better. Encryption protects our emails, our Continue reading

Modernizing your network has never been easier with Cumulus NetQ Lifecycle Management

Upgrade and configuration management with push button simplicity

Network operations is all about keeping the network running smoothly and without problems. It includes monitoring the network for performance problems and faults, as well as fixing problems before they affect end users, or at least in the timeliest manner possible. Managing network assets correctly is critical to avoiding application-impacting network outages, performance degradation and security incidents.

However, network operators often struggle with operational challenges such as network disruptions caused by maintenance and configuration changes. Furthermore, business networks are often fairly large and complex, which means the set of tasks a network administrator will need to perform can quickly overwhelm manual efforts. This requires a shift, not only to modern networking, but also to modern operational tools as well.

To help solve these issues, Cumulus Networks has added new lifecycle management (LCM) capabilities to Cumulus NetQ 3.0, offering a simple GUI-driven workflow for provisioning, operating, maintaining and retiring network switches running Cumulus Linux.

Figure 1: NetQ Lifecycle Management

With the addition of full lifecycle management functionality, NetQ 3.0 now combines the ability to easily upgrade, configure and deploy network elements with a full suite of operations capabilities, such as visibility, Continue reading

Creating a True One-Stop Solution for Companies to Go Global: Announcing a Partnership Between Cloudflare and JD Cloud & AI

It’s well known that global companies can face challenges doing business in and out of China due to the country’s unique rules, regulations, and norms, not to mention recent political and trade complications. Less well known is that China’s logistical and technical network infrastructure is also quite different from the rest of the world’s. With global Internet traffic up 30% over the past month due to the pandemic, these logistical and technical hurdles are increasing the burden for global businesses at exactly the wrong time. It’s now not unusual for someone based in China to have to wait extended periods and often be unable to access applications hosted elsewhere, or vice-versa, due to the lower performance of international Internet traffic to and from China. This affects global companies with customers, suppliers or employees in China, and Chinese companies who are trying to reach global users.

Our mission is to help build a better Internet, for everyone, everywhere. So, today we’re excited to announce a significant strategic partnership with JD Cloud & AI, the cloud and intelligent technology business unit of Chinese Internet giant JD.com. Through this partnership, we’ll be adding 150 data centers in mainland China, an increase in Continue reading

CML-P – Why 20 Nodes Is Not Enough

Intro

Cisco recently announced that they are releasing CML-P, which is version two of the product formerly known as VIRL. First of all, I’ve seen the product demoed and helped with feedback on it, it looks stunning! The architecture looks great, it’s fully leveraging APIs and it’s an entirely different beast than VIRL. This is a great product and I want to see it succeed. Unfortunately, this product is never going to be as successful as it could be. Why?

CML-P

CML-P, where P stands for Private, supports a maximum of 20 nodes. This is supposed to be a differentiator to the the -E version, which is for enterprises that wish to run this product at larger scale, including support. First of all, I don’t agree that a node limit is the proper way to differentiate -P from -E. That can be done through support, training and other means.

CML-P Competition

CML-P’s competition is going to be GNS3 and EVE-NG. These are freely available, but also offer paid versions with a more advanced feature set. There is no node limit with these products. You can run as much as your server can handle. If CML-P is going to compete Continue reading
