SEC 3. Building your own containerised PKI (root CA) with Linux and Docker to simplify and secure network automation

Hello my friend,

You know our passion to network automation. We truly believe, that this is the only sustainable way for the network development and operation. In the same time, one the key goals of the automation is to make your network secure and safe. Therefore, the security of the automation and communication channels used by automation is very important. So today we’ll take a look how to build

Can automation make your network better?

Automation is the key component of the perpetual engine of your network development and operation. It allows you to run the network quick, stable, and safe. And we are willing you to benefit as much as you can from that.

We have created a new training, which is focused only on the Nornir and you can use it for the network (and not only) automation. It is an organic extension of our network automation training, which assumes you are already Continue reading

Smart ways to compare files on Linux

Commands for comparing files have proliferated since the early days of Linux. In this post, we'll look at a suite of commands available for comparing files and highlight the advantages that some of the newer ones provide.diff One of the oldest and still popular commands for detecting and reporting on file differences is the diff command. Comparing two lists of meeting attendees, the diff command will simply and clearly show you the differences.$ diff attendance-2020 attendance-2021 10,12c10 < Monroe Landry < Jonathon Moody < Donnell Moore --- > Sandra Henry-Stocker Only the lines that are different are displayed.

On the ‘net: The Art of Conviction

I was recently a guest on The Art of Conviction podcast, where we covered a bit of my background, some of the challenges I’ve faced in getting where I am, and then we moved into a discussion around my recently finished dissertation. I’m working to find places to publish more in the area of worldview and culture; I’ll point to those here as I can find a “home” for that side of my life.

You can find the recording here.

Beyond my episode, The Art of Conviction is a fascinating podcast; you should really subscribe and listen in.

Industry-First Pay-as-you-go SaaS Platform for Kubernetes Security and Observability

We are excited to introduce Calico Cloud, a pay-as-you-go SaaS platform for Kubernetes security and observability. With Calico Cloud, users only pay for services consumed and are billed monthly, getting immediate value without upfront investment.

Introduction

Calico Cloud gives DevOps, DevSecOps, and Site Reliability Engineering (SRE) teams a single pane of glass across multi-cluster and multi-cloud Kubernetes environments to deploy a standard set of egress access controls, enforce security policies, ensure compliance, get end-to-end visibility, and troubleshoot applications. Calico Cloud is Kubernetes-native and provides native extensions to enable security and observability as code for easy and consistent enforcement across Kubernetes distributions, multi-cloud and hybrid environments. It scales automatically with the managed clusters according to the user requirements to ensure uninterrupted real-time visibility at any scale.

Security and Observability Challenges

  • North-South Controls: Often microservices need to communicate with services or API endpoints running outside the Kubernetes cluster. Implementing access control from Kubernetes pods to external endpoints is hard. Most traditional or cloud provider’s firewalls do not understand the Kubernetes context which forces the ops team to allow traffic from the entire cluster or a set of worker nodes.
  • East-West Controls: Even after effective perimeter-based north-south controls, the organizations face challenges to Continue reading

Availability Zones and Regions in AWS, Azure and GCP

My friend Daniel Dib sent me this interesting question:

As I understand it, subnets in Azure span availability zones. Do you see any drawback to this? Does subnet matter if your VMs are in different AZs?

I’m positive I don’t have to tell you what networks, subnets, and VRFs are, but you might not have worked with public cloud availability zones before. Before going into the details of Daniel’s question (and it will take us three blog posts to get to the end), let’s introduce regions and availability zones (you’ll find more details in AWS Networking and Azure Networking webinars).
