Vendor Lock-In. Maybe Not So Evil. (Video)
Is vendor lock-in all that bad? Many argue yes. You’re tied to a vendor because you’ve used some of their proprietary technology, and so you’re (apparently) stuck with it forever, limiting your future business agility. I think that’s an incomplete argument, though.
Exploiting the “Legacy Tax” Loophole for HPC Storage
Over the next few years, we can expect to hear even more about large-scale computing sites bumping up against the memory wall, although not necessarily where they might expect. …

Tools 1. Top 5 tools for network performance troubleshooting
Hello my friend,
some time ago we’ve been recently engaged in the troubleshooting of the performance issues. Namely, the speed of the communication between the application’s endpoints in two data centres was not persistent. Instead, it was deviating a lot having multiple TCP retransmissions for certain flows. The issues was successfully solved, and we’d like to share with you the tools we have used to identify and validate various aspects of traffic forwarding.

Can automation help with performance troubleshooting?
Absolutely. During our network automation training we show how to utilise various Linux tools from configuration management tools (e.g. Ansible) and programming languages (Bash, Python). That gives you ready examples from our training, which you can use in your network immediately, and endless possibilities to create your own automated troubleshooting workflows.
Our network automation training has two faces: either live or self-paced. So you can choose yourself, what works better for you. On our side, we Continue reading

Introducing the Ansible Content Collection for Red Hat OpenShift
Increasing business demands are driving the need for automation to support rapid, yet stable and reliable deployments of applications and supporting infrastructure. Kubernetes and cloud-native tools have quickly emerged as the enabling technologies essential for organizations to build the scalable open hybrid cloud solutions of tomorrow. This is why Red Hat has developed the Red Hat OpenShift Container Platform (OCP) to enable enterprises to meet these emerging business and technical challenges. Red Hat OpenShift brings together Kubernetes and other cloud-native technologies into a single, consistent platform that has been fine-tuned and enhanced for the enterprise.
There are many similarities to how Red Hat OpenShift and Red Hat Ansible Automation Platform approach their individual problem domains that make a natural fit when we bring the two together to help make hard things easier through automation and orchestration.
We’ve released the Ansible Content Collection for Red Hat OpenShift (redhat.openshift) to enable the automation and management of Red Hat OpenShift clusters. This is the latest edition to the certified content available to subscribers of Red Hat Ansible Automation Platform in the Ansible Automation Hub.
In this blog post, we will go over what you’ll find in redhat.openshift Continue reading
Onno Purbo: 2020 Postel Award Winner Uses Human Touch to Bridge the Digital Divide
Onno Purbo is a people person. It’s not typically something you hear about an engineer. But it is through his approach to education in the Internet sphere that Indonesian villages have access at all.
“The other engineers, they are very much engineer,” Purbo said. “A problem is solved by coding, is solved by an antenna, is solved by a product of some kind. My approach is a more human approach. Most engineers introduce their products, I give people the knowledge.”
Purbo, as this year’s Jonathan B. Postel Award winner, uses his experience, knowledge, and expertise not only to build networks and improve access for his fellow Indonesians, but to teach them how to do it themselves. He does this through hours of work on social media channels, speaking one-on-one with hundreds of thousands of followers whenever they have questions or concerns.
“I use social media as a free, huge class[room]. Effective and efficient empowerment processes were not possible with the old mechanism where we would rent rooms or buildings with professional event organizers,” Purbo said. “These days, for example, thousands of viewers may easily view any of my videos on YouTube.”

Network-layer DDoS attack trends for Q3 2020
DDoS attacks are surging — both in frequency and sophistication. After doubling from Q1 to Q2, the total number of network layer attacks observed in Q3 doubled again — resulting in a 4x increase in number compared to the pre-COVID levels in the first quarter. Cloudflare also observed more attack vectors deployed than ever — in fact, while SYN, RST, and UDP floods continue to dominate the landscape, we saw an explosion in protocol specific attacks such as mDNS, Memcached, and Jenkins DoS attacks.
Here are other key network layer DDoS trends we observed in Q3:
- Majority of the attacks are under 500 Mbps and 1 Mpps — both still suffice to cause service disruptions
- We continue to see a majority of attacks be under 1 hr in duration
- Ransom-driven DDoS attacks (RDDoS) are on the rise as groups claiming to be Fancy Bear, Cozy Bear and the Lazarus Group extort organizations around the world. As of this writing, the ransom campaign is still ongoing. See a special note on this below.
Number of attacks
The total number of L3/4 DDoS attacks we observe on our network continues to increase substantially, as indicated in the graph below. All in all, Continue reading
