In 2014, Cloudflare set out to encrypt the Internet by introducing Universal SSL. It made getting an SSL/TLS certificate free and easy at a time when doing so was neither free, nor easy. Overnight millions of websites had a secure connection between the user’s browser and Cloudflare.
But getting the connection encrypted from Cloudflare to the customer’s origin server was more complex. Since Cloudflare and all browsers supported SSL/TLS, the connection between the browser and Cloudflare could be instantly secured. But back in 2014 configuring an origin server with an SSL/TLS certificate was complex, expensive, and sometimes not even possible.
And so we relied on users to configure the best security level for their origin server. Later we added a service that detects and recommends the highest level of security for the connection between Cloudflare and the origin server. We also introduced free origin server certificates for customers who didn’t want to get a certificate elsewhere.
Today, we’re going even further. Cloudflare will shortly find the most secure connection possible to our customers’ origin servers and use it, automatically. Doing this correctly, at scale, while not breaking a customer’s service is very complicated. This blog post explains how we are Continue reading
netlab release 1.3 introduced support for VXLAN transport with static ingress replication and EVPN control plane. Last week we replaced a VLAN trunk with VXLAN transport, now we’ll replace static ingress replication with EVPN control plane.

Bruce Davie makes an excellent point in his QUIC Is Not a TCP Replacement article – QUIC not a next-generation TCP, it’s a reliable RPC transport protocol.
What Bruce forgot to mention is that we had a production-grade RPC transport protocol for years – SCTP (Stream Control Transmission Protocol) – but it had two shortcomings:

In this post, I will show you how to Dockerize your Rails 7 app in a development environment. We will be using Tailwind for the CSS and PostgreSQL for the database. This setup includes hot reloading of assets on file changes which is super nice. Software used in this post Docker -...continue reading
Jeroen Van Bemmel created another interesting netlab topology: EVPN/VXLAN between SR Linux fabric and FRR on Linux hosts based on his work implementing VRFs, VXLAN, and EVPN on FRR in netlab release 1.3.1.
Bonus point: he also described how to do multi-vendor interoperability testing with netlab.
If only he wouldn’t be publishing his articles on a platform that’s almost as user-data-craving as Google.

I was lucky enough to have been invited to attend Network Field Day 29 this past September in San Jose, CA. This event brings independent thought leaders together with a number of IT product vendors to share information and opinions. We saw presentations from a pretty full range of vendors — from the chips to observability. It was a great event and worth a few hours to check out the videos. Thanks to Gestalt IT for getting me involved.
Nokia was among the list of high-end companies we saw. No, they don’t make phones any more (though they do market their name to products), but they are still in the full-power, throw-packets-as-fast-as-you-can markets for hyperscalers and such. If you’re old like I am, you might remember Nokia as the hardware that Checkpoint ran on for a while. My brain has done its best to filter memories of those devices, but, luckily, the Nokia team is doing some much better things these days.
SR Linux was one of the focuses and the big hitter for me. This is a modernization of the SR OS that was introduced 20 years or so ago, and gets us into a “world of streaming telemetry. Continue reading

In the realm of data security, HashiCorp Vault emerges as a formidable tool for safeguarding sensitive information. Its primary role? To serve as a secure and encrypted repository for your most prized secrets. Whether you choose to manage it independently through the open-source option or opt for the convenience of HashiCorp Cloud Platform's SaaS solution, Vault stands as a reliable guardian of your data, ensuring confidentiality and integrity are upheld with every interaction.
The Vault HTTP API serves as a versatile gateway, granting comprehensive control over Vault's functionalities through simple HTTP requests. Whether you're delving into secrets management or tackling encryption tasks, this API opens the door to Vault's full potential. And for Python enthusiasts like myself, there's an added layer of convenience: a meticulously crafted Python SDK, complete with thorough documentation, streamlining interactions with Vault.
In this blog post, we'll embark on a journey to set up a self-managed instance of Vault, exploring how to seamlessly integrate Python for streamlined interaction with the platform.
We'll kick start our Vault journey by spinning up an instance using Docker. To achieve this, we'll craft a docker-compose.yml file to orchestrate the process:
version: "3.9"
services:
hashicorp-vault:
build: .
ports:
