An enterprise customer that wants certain preferences is an example of a context-aware networking.
One of my readers wanted to implement a large DMVPN cloud with regional Internet exit points:
We need to deploy a regional Internet exits and I’d like to centralize them. Each location with a local Internet exit will be in a region and that location will advertise a default-route into the DMVPN domain to only those spokes in that particular region.
He wasn’t particularly happy with the idea of deploying access and core DMVPN clouds:

Kubernetes networking 101 – Pods
Kubernetes networking 101 – Services
Kubernetes networking 101 – (Basic) External access into the cluster
Kubernetes Networking 101 – Ingress resources
My goal with these posts has been to focus on the primitives and to show how a Kubernetes cluster handles networking internally as well as how it interacts with the upstream or external network. Now that we’ve seen that, I want to dig into a networking plugin for Kubernetes – Calico. Calico is interesting to me as a network engineer because of wide variety of functionality that it offers. To start with though, we’re going to focus on a basic installation. To do that, I’ve updated my Ansible playbook for deploying Kubernetes to incorporate Calico. The playbook can be found here. If you’ve been following along up until this point, you have a couple of options.

There are a lot of REST APIs out there. Quite a few of them use JSON as the data structure which allows us to get data in and out of these devices. There are a lot of network focused blogs that detail how to send and receive data in and out of these devices, but I wasn’t able to find anything that specifically talked about validating the input and output of the data to make sure we’re sending and receiving the expected information.
Testing is a crucial, and IMO too often overlooked, part of the Infrastructure as Code movement. Hopefully this post will help others start to think more about validating input and output of these APIs, or at the very least, spend just a little more time thinking about testing your API interactions before you decide to automate the massive explosion of your infrastructure with a poorly tested script.
I’m assuming that you already know what JSON is, so let’s skip directly to talking about JsonSchema. This is a pythonlibrary which allows you to take your input/output and verify it against a known schema which defined the data types you’re expecting to see.
For example, consider Continue reading

What is happening with the WannaCry ransomware that has been attacking unpatched Windows computers around the world? How will it all end? What do we need to do collectively to deal with attacks like this? (Hint: Read Olaf's post.)
To learn more and pose questions to a panel of experts, you can join our partners at the Geneva Internet Platform and Diplo Foundation for a webinar on "Decrypting the WannaCry ransomware: Why is it happening and (how) is it going to end?"
The biggest problem with IoT security is that most devices are going to be relatively simple and inexpensive connected things. The bandwidth consumption of these devices should be kept to the minimum to save bandwidth. Yet at the same time, security is supposed to be a continuous process. This involves a party that is responsible for keeping an eye on the various security vulnerabilities that emerge from time to time, and another one to make sure that suitable patches are being prepared and applied on timely basis. —CircleID
