AWS DeepLens and Telegram saving bird’s food and plants from my Dog!

Weekend project after a while!. Not Long ago, I did mention that my cute Dog is responsible for destructing most of the wall and paper, when enquired pro’s said its part of puppy growing up and it still needs time.Along with Dog, I personally would love to feed and enjoy petting other species to be honest out of which birds and plants are major, there are earthworms and sea life but Dog is not a threat to them based on the placement.

AWS DeepLens

https://aws.amazon.com/deeplens/ – Is ML/AI enabled camera which can be used at edge inferencing. Slipping down to my usual choice of words, this piece of equipment has an onboard camera , a Gpu , a Cpu and ubuntu host OS. Easily integrates with AWS and runs a local Lambda for inferencing, hence decisions are made on the device instead of reaching out to AWS to do the logic.

What is the problem!

Worth Exploring: Magic Carpet

Looks like John changed the name of the project and all the URLs. Will update the links once he’s done with the migration.

John Capobianco recently released his Magic Carpet: a tool that helps you gather information from network devices without the usual Ansible bloat and glacial speed.

Believing in “no job is finished until the paperwork is done”, he wrote extensive documentation, and recorded a collection of videos describing the tool’s functionality – definitely worth reading, watching, and exploring.

Networking Isn’t Just A Tool

BlueFiberOptic

It’s another event week for me at Networking Field Day 25 and I’m continually impressed with the level of technology that we see in the networking world. I think back to how things looked when I was still deploying the networks I built and it seems like a hundred years ago instead of a decade. More software driving better outcomes for users. Easier collection of analytics and telemetry to understand how to tune things and make them faster and better. And, honestly, more need for advanced technical people to tune everything and make it work better.

When you consider that the last year has been done over the Internet for most of us it gets even crazier. Meetings, software productivity, and even food delivery has been driven by apps running in the cloud that we communicate with over the Internet. I can remember a time when I didn’t have a mobile phone in my pocket with Internet capabilities. Today I can barely imagine not having it at my fingertips. When the network is not doing things the way we want we quickly find out how dependent we’ve become on our connectivity.

For this post, I wanted to explore some ways that an organisation or individual might start building a new security “habit” so that, in time, acting securely becomes automatic.


Research into methods of attacking machine-learning and artificial-intelligence systems has surged—with nearly 2,000 papers published on the topic in one repository over the last decade—but organizations have not adopted commensurate strategies to ensure that the decisions made by AI systems are trustworthy


Efforts have been ongoing in the ICANN community to develop a better understanding of its role in the combat of abuse.


But the Advanced Persistent Threat (APT) carries with it a worrying sub-text that requires further exploration as companies continue to tackle the ongoing issues of a global pandemic and an increasingly fatigued and remote workforce.


With organizational data practices coming under increasing scrutiny, demand is growing for mechanisms that can assist organizations in meeting their data-management obligations


All good parties come to an end, and the one that Intel has enjoyed for an unbelievable dozen years, starting with the rollout of the “Nehalem” Xeon E5500 processors back in March 2009, is over. Find the Advil, grab a glass of water, and try not to drop all the pills Continue reading

Tetrate Service Bridge to Close Enterprise Application Networking Gap via Service Mesh

At some point, you’ve got to stop building something you think people need and start putting it out there to test in the market. You have to go get users. This is where the first engineers of the Istio service mesh at Google found themselves about four years ago. But, like many things in the still-emerging cloud native space, the first response was: Well, what is it? Who else is using it? Tetrate Service Bridge to act as an application connectivity platform or a technical bridge to take you from those legacies to those modern environments, and to increase reliability and availability. Also called TSB, it looks to solve the issue of networking for heterogeneous workloads. Tetrate Service Bridge, built on Istio and now in general availability, presents itself as the solution to enterprise-grade challenges that can’t be just abstracted out with a Kubernetes layer. The Tetrate team has built out the core set of functionality around controlling traffic across an entire fleet of services, from the edge to the mesh. Butcher says TSB bridges the gap between having service mesh capabilities and actually realizing those capabilities in a way that is safe. He said, “This service mesh is great, but how do I actually use it in my enterprise? How do I change my process to take advantage of the mesh? And actually changing processes is really expensive, so how do I not change my process either?” And those enterprise processes aren’t simple either. They look to use service mesh to enforce security and compliance requirements. Or to gain control and visibility across entire complex infrastructures. How to put security controls in place across highly heterogeneous environments. “Service mesh serves a lot of problems I have but you are telling me I can only have it in Kubernetes? I want those things to help me get from my legacy to a modern environment, not already in that,” Butcher said. TSB helps you manage across the full breadth of compute, connecting Kubernetes and legacy infrastructure. He gives examples you can use to link with Istio and Envoy and just start assembling your application network. “Tetrate Service Bridge is a platform for applications to communicate securely and successfully without having to get into the weeds of what lives there.”— Zack Butcher, Founding Engineer, Tetrate Butcher says then there’s the enterprise management side, teams need to be able to prove they are using service mesh correctly and securely. He says TSB enables teams to divvy up their physical infrastructure and cloud-based environments, with multitenancy and controls, so you can use service mesh to “do cool things at runtime.” The connectivity tool works not only with Istio and the Apache Skywalking, enabling observability across whole systems. They are clear that while they are a tool to ease the use of these open source tools and the whole Tetrate team is contributors to the open source projects they depend on, they are not an open core company, intentionally. “In my opinion, there’s this really big tension in open-core companies. If me, as a developer, I have to decide project or product that people pay for — he doesn’t want to make the value prop decision,” Butcher explained. He continued, “We are building a layer on top of the open source pieces. We are assembling these open source pieces together in a coherent system.” Another part of this decision is that, since they are still essentially using open source tools, enterprises can do so in a relatively cheap way through Tetrate. Butcher points to the fundamental difference between enterprise closed source products like TCB and the open source projects it serves. “Capabilities go in open source and then how you manage those capabilities and how you use them within an organization, that’s what you put in the product,” he said.” While they only went fully public with TSB in April, they built it alongside adopters from the start. Butcher, paraphrasing Socrates, said that after the “pain of adopting Istio — we were in a cave without users” they were determined to build hand in hand with users. One such early adopter was FICO, the organization that creates the predominant credit risk score in the U.S. One emerging use case for service mesh is encryption in transit to ensure compliance to ever-changing regulations and standards from HIPAA and GDPR to automate enforcement of

Automating Cloudflare Tunnel with Terraform

Automating Cloudflare Tunnel with Terraform
Automating Cloudflare Tunnel with Terraform

Cloudflare Tunnel allows you to connect applications securely and quickly to Cloudflare’s edge. With Cloudflare Tunnel, teams can expose anything to the world, from internal subnets to containers, in a secure and fast way. Thanks to recent developments with our Terraform provider and the advent of Named Tunnels it’s never been easier to spin up.

Classic Tunnels to Named Tunnels

Historically, the biggest limitation to using Cloudflare Tunnel at scale was that the process to create a tunnel was manual. A user needed to download the binary for their OS, install/compile it, and then run the command cloudflared tunnel login. This would open a browser to their Cloudflare account so they could download a cert.pem file to authenticate their tunnel against Cloudflare’s edge with their account.

With the jump to Named Tunnels and a supported API endpoint Cloudflare users can automate this manual process. Named Tunnels also moved to allow a .json file for the origin side tunnel credentials instead of (or with) the cert.pem file. It has been a dream of mine since joining Cloudflare to write a Cloudflare Tunnel as code, along with my instance/application, and deploy it while I go walk my dog. Tooling should Continue reading

SP. Part 9. Health check of Segment Routing Traffic Engineering (SR-TE) tunnels with seamless BFD in Nokia SR OS

Hello my friend,

For a long time we haven’t posted blogs about pure network technologies. However, recently we were working on some interesting use case, which so far is not yet covered at a level of the working details nowhere in the internet. As such, we decided to share with you our findings and working details.

How automation can help with SR-TE in SP network?

In some (big) networks the BGP-SR-TE is a good signal the SR-TE policies, so that the PE routers can build the SR-TE tunnels without the need to configure them locally. However, the BGP-SR-TE requires a full pledged SDN controller, so that you can generate the SR-TE policy in the backend using some UI/API and send the policies down to the network elements using the BGP. If you want to have a somewhat simpler setup, you may need need to deploy the tunnels manually. In this case, the automation is your closest Continue reading
