Listen to this Q&A session between SDxCentral Editor Matt Kapko and 7 Layers host Connor...
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:
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.
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.
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.
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

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.
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.
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.
With NetQ 3.0, Cumulus adds lifecycle management capabilities to make it easier to roll out updates...
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
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.
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
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
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, 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’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
