Journey Through Open Networking
Arista has a decade long history of collaboration in open networking. We have pushed the envelope, co-developed open platforms and deployed them to build the world’s largest cloud -scale networks.
Feedback: How Networks Really Work
In early April 2020 I ran another live session in my How Networks Really Work webinar. It was supposed to be an easy one, explaining the concepts of packet forwarding and routing protocols… but of course I decided to cover most solutions we’ve encountered in the last 50 years, ranging from Virtual Circuits and Source Route Bridging to Segment Routing (which, when you think about it, is just slightly better SRB over IPv6), so I never got to routing protocols.
That webinar was supposed to be an introductory one, but of course I got pulled down all sorts of rabbit trails, and even as I was explaining interesting stuff I realized a beginner would have a really hard time following along… but then I silently gave up. Obviously I’m not meant to create introduction-to-something material.
Reducing Your Database Hosting Costs: DigitalOcean vs. AWS vs. Azure
If you’re hosting your databases in the cloud, choosing the right cloud service provider is a significant decision to make for your long-term hosting costs. This is especially apparent in today's world where organizations are doing whatever they can to optimize and reduce their costs. Over the last few weeks, we have been inundated with requests from SMB customers looking to improve the ROI on their database hosting. In this article, we are going to compare three of the most popular cloud providers, AWS vs. Azure vs. DigitalOcean for their database hosting costs for MongoDB® database to help you decide which cloud is best for your business.

AnsibleFest 2020 is now a virtual experience
Each year, AnsibleFest is one of our favorite events because it brings together our customers, partners, community members and Red Hatters to talk about the open source innovations and best practices that are enabling the future of enterprise technology and automation.
Because the safety of our attendees is our first priority, we have decided to make AnsibleFest 2020 a virtual experience. We are excited to connect with everyone virtually, and look forward to expanding our conversation across the globe. By changing our event platform, we hope to use this opportunity to collaborate, connect, and chat with more automation fans than ever before. It is exciting to think about how many more people will be able to join in on the automation conversation.
The AnsibleFest Virtual Experience will be a free, immersive multi-day event the week of October 12th, 2020, that will deliver timely and useful customer keynotes, breakout sessions, direct access to Ansible experts, and more. You will want to sign up to stay connected and up-to-date on all things AnsibleFest on the AnsibleFest page.
Call for proposals is open
We are still working through the details for the virtual event, but are very excited to announce that Continue reading
SONiC and White Box switches in the Enterprise DC! – Part 1
In recent years two buzz words began to arise: open-networking and white box switches. Those two words go often hand-in-hand with each other. They are often promoted by big names like Facebook or Microsoft.
From the software side, SONiC is maybe the biggest player out there as it powers Microsoft Azure’s cloud, while from the hardware side, Accton has arguably been one of the most important vendors.
The truth though, at least in my opinion, is that while this innovation is great it is not ready to be embraced by everyone yet. Only companies willing to make this “leap of faith” can take advantage of all of this, but what about us poor mortals? Are SONiC and white boxes ready to be widely deployed? Well let’s give it a look!
We will be deploying a simple VXLAN-EVPN Fabric like in the picture below and we will be checking how difficult is to configure and troubleshoot the fabric, but also and most importantly if this common Enterprise design actually works.
The Hardware
For our spines we’ll be using Edge-Core’s AS7816-64X, powered by Broadcom’s Tomahawk II chipset. This switch is a 2RU lean spine providing 64x 40/100 Gbps QSF28 ports.

The Week in Internet News: Hackers Revamp Malware With COVID-19 Messages
Taking advantage: Cyberattackers are reconfiguring the Remcos trojan, which allows them full access to victims’ computers, to include COVID-19 warnings in spam and phishing emails, Security Boulevard reports. “With the economy directly affected by the pandemic, people pay more attention to emails pretending to offer solutions, loans and other types of financial support. Another effective approach is to scare people with threats of account closures or company furloughs.”
The impact of a shutdown: An ongoing phone and Internet service shutdown in the Kashmir region is hurting the ability to distribute information and supplies during the COVID-19 pandemic, Greater Kashmir says. “People in need of essentials used to reach out to us on our helplines which have turned defunct,” said the chairman of an aid agency. “We used to make phone calls to our existing 750 beneficiaries for conveying them about timings to pick up their quota of essentials. But suspension of mobile networks has disturbed this entire process.”
Cooperative Internet service: The Christian Science Monitor has a story about small rural cooperatives building their own Internet services. Cooperatives, which are private businesses owned by customers, are common in parts of the U.S. Midwest, some providing electricity and Continue reading
Using Cisco ACI as Inventory for Ansible Tower
Managing a software-defined networking (SDN) solution in Ansible can be tricky. In most use cases, Ansible communicates with each managed node individually. However, in a SDN scenario, Ansible is most likely managing policy on a controller appliance, which ultimately may make changes to thousands of network endpoints behind it.
But what about these endpoints behind that controller abstraction? Wouldn't it be best if Ansible Tower had visibility to every node, in addition to the controller? Not to run playbooks directly against those nodes, but for the following reasons:
- Many organizations need to perform capacity planning against current and projected license usage. Ansible Tower provides license usage data, but it's not accurate if Ansible Tower only knows about the SDN controller(s).
- Networking teams are still asked for physical node information by other IT areas, even if the focus is on a software-defined fabric. What if the best system to get that data from is Ansible Tower? You may not want a CMDB probe (for example) to communicate directly with the SDN controller, or Ansible Tower may already be home to similar data about other systems.
Inventory plugin for Cisco ACI
I wrote an Ansible inventory plugin that solves these issues Continue reading

GNMI. Part 1. Intro to Protobuf.
Hello my friend,
Some time ago we have covered in-depth OpenConfig with NETCONF configuration as well as the OpenConfig telemetry with NETCONF. Today we want to make a next step and start discussion about another approach to manage the network elements in a programmatic way, which is gNMI.
