Today on the Tech Bytes podcast we’re talk network security at scale. That is, in a cloud environment, how can you build security capabilities and features into the network while also being able to keep up with security policies, operations, compliance, and more. Our sponsor is Aviatrix, which provides multi-cloud networking software for public clouds.

This week's Network Break looks at new router silicon from Juniper, why NVIDIA's acquisition bid for Arm is running into headwinds, a new LiveAction service that inspects encrypted traffic for threats, financial results from Juniper and Extreme, and more tech news.

The importance of the Cloudflare Partner Network was on full display in 2021, with record level partner growth in 2021 and aiming even higher in 2022. We’ve been listening to our partners and working to constantly strengthen our ability to deliver value for businesses of all types. An area we identified we could do better, is a program to support “service partners” that want to wrap managed and professional services around Cloudflare products. Today, we are excited to announce the next evolution of the Cloudflare Channel and Alliances Partner Program to specifically enable partners that provide services around Cloudflare products with recurring revenue streams as they equip businesses of all sizes and types with Cloudflare’s leading Zero Trust and SASE solutions.
Core to enabling Services Partners are some exciting enhancements:
We have seen a 29% increase in ransom DDoS attacks over the past year and a 175% increase just last quarter. Partners continue to be on the front lines helping mitigate and prevent disruption from these events as they extend our services. Our goal for 2022 is to arm our partners with the Continue reading
Last week I took and passed the AWS Certified Advanced Networking – Specialty exam on my first attempt. In this post I will describe the study materials that I used and talk about my experience of taking this test.
What type of skills does this exam test? This is a quote from AWS:
Earning AWS Certified Advanced Networking – Specialty validates expertise in designing and maintaining network architecture for the breadth of AWS services.
The key here I think is “for breadth of AWS services”. It’s not enough to only understand general networking in AWS, you need to understand how to do networking for different AWS services such as S3, WorkSpaces, Lambda, storage gateway, and so on. There is no actual prerequisite to take the exam but it definitely doesn’t hurt if you already have the Solutions Architect Associate (this was previously a prereq) as it will help you in understanding what services are available.
The following is also listed as recommendations for who should take this exam:
Last week I published a link to Pete Crocker’s RSVP-TE lab, but there’s more: he created another lab using the same topology that uses SR-MPLS with IS-IS to get the job done.
Jeroen Van Bemmel did something similar for SR Linux: his lab topology has fewer devices (plus SR Linux runs in containers), so it’s easily deployable on machines without humongous amount of memory.
I just passed the Cisco DevNet DCAUTO (300-635) exam (Yay!). This is my 3rd Cisco exam on network automation after NPDESI in 2018 (replaced now by the DevNet program), and DevNet CORE (DEVCOR) in 2020. But this time, I documented everything I read, so I could report it here and build a Cisco DCAUTO exam study resources. By doing this, I hope to help anyone who wants to study for this certification. And, as I have already passed the DevNet CORE exam, I am now Cisco certified DevNet Professional. …

Hello my friend,
Right before the New Year we have posted an article, where we introduced a new approach to manage Cumulus Linux, which became available in the latest release to the date Cumulus Linux 5.0. This approach relies on REST API, which makes the automation of this platform very comfortable. Today we’ll cover how to collect the configuration and ope data with the most popular network and infrastructure automation tools these days: Ansible and Python.

To be absolutely frank, there is no “or”. There is only “and” in such a question. Both Ansible and Python play crucial role in network and infrastructure automation. Both of them are widely used in various companies from small enterprise to gigantic tier-1 web companies (e.g., Google, Amazon, etc). We see different usage patterns, such as Ansible + AWX being a main toolkit, or Python + Stackstorm or Apache Airflow Continue reading
Tom Hollingsworth published a more eloquent version of what I’ve been saying for ages:
Obviously it’s totally against the vested interest of any networking vendor out there to admit it.
BGP EVPN with VXLAN to the multi-tenant hosts (using SR Linux and SR OS)
There are many ways to do things, and some ways are subjectively better than others. Sometimes, things that may have been a Bad Idea™ in the past become a Not_So_Bad_After_All(maybe, provided X and not Y) option in light of new developments or concerns. To tell which one is which, we’ll just have to give it a go and see where we end up. And whatever happens — 🤞 chances are we’ll learn some things in the process regardless!
“Accelerating waves of change to open (2021)” paints a picture of how we can see things evolving over time. From hardware to software, from L2 to static L3 to dynamically signaled L3 with BGP to VXLAN (L2-over-L3) — it all follows a similar pattern of evolutionary change, building on technology from the past to create the future, following the path of the adjacent possible. The terminology and acronyms we humans Continue reading
Christoph Jaggi, the author of Ethernet Encryption webinar and ethernet encryptor market overviews launched a new site in which he collected tons material he created in the past – the network security and news and articles sections are definitely worth exploring.
