The story of web framework Hono, from the creator of Hono
Hono is a fast, lightweight web framework that runs anywhere JavaScript does, built with Web Standards. Of course, it runs on Cloudflare Workers.
It was three years ago, in December 2021. At that time, I wanted to create applications for Cloudflare Workers, but the code became verbose without using a framework, and couldn't find a framework that suited my needs. Itty-router was very nice but too simple. Worktop and Sunder did the same things I wanted to do, but their APIs weren't quite to my liking. I was also interested in creating a router — a program that determines which action is executed based on the HTTP method and URL path of the Request — made of a Trie tree structure because it’s fast. So, I started building a web framework with a Trie tree-based router.
“While trying to create my applications, I ended up creating my framework for them.” — a classic example of yak shaving. However, Hono is now used by many developers, including Cloudflare, which uses Hono in core products. So, this journey into the depths of yak shaving was ultimately meaningful.
Hono truly runs anywhere — not just on Cloudflare Continue reading

Comparing IP and CLNP: Finding Adjacent Nodes
Now that we know a bit more about addresses in a networking stack (read the whole series) and why CLNP uses node addresses while TCP/IP uses interface addresses, let’s see how they solve common addressing problems like finding adjacent nodes.
Let’s start with the elephant in the room: how do you know whether you can reach a host you want to communicate with directly? In the following diagram, how does A know whether B is sitting next to it?
Adding ADCS Role to ISE Lab Domain Controller
This post describes how to install Active Directory Certificate Services (ADCS) onto a domain controller. It’s for labbing purposes which means I’m going to run this all on a single server instead of a more realistic setup with offline root, issuing CA, and possibly intermediate CA. Don’t use this post for anything designed to go into production!
To add the ADCS role. Go to Server Manager, click Add roles and features. Click Next until you get to Server Roles. Select Active Directory Certificate Series:
Click Add Features. Click Next. Click Next. Then a warning is displayed that it’s not possible to change the computer name or domain settings:
Click Next. Select Certification Authority and Certification Authority Web Enrollment:
Selecting Certification Authority Web Enrollment will install IIS and a small web site will be built to provide certificate services.
Click Add Features. Click Next. Click Next. Select Restart the destination server automatically if required:
Click Install. The installation starts:
When the installation has finished, click Close. Click AD CS in Server Manager. Click More… where it says Configuration required for Active Directory Certificate Services:
Click Configure Active Directory Certificate Services on the destination server:

Analysis of the EPYC 145% performance gain in Cloudflare Gen 12 servers
Cloudflare's network spans more than 330 cities in over 120 countries, serving over 60 million HTTP requests per second and 39 million DNS queries per second on average. These numbers will continue to grow, and at an accelerating pace, as will Cloudflare’s infrastructure to support them. While we can continue to scale out by deploying more servers, it is also paramount for us to develop and deploy more performant and more efficient servers.
At the heart of each server is the processor (central processing unit, or CPU). Even though many aspects of a server rack can be redesigned to improve the cost to serve a request, CPU remains the biggest lever, as it is typically the primary compute resource in a server, and the primary enabler of new technologies.
Cloudflare’s 12th Generation server with AMD EPYC 9684-X (codenamed Genoa-X) is 145% more performant and 63% more efficient. These are big numbers, but where do the performance gains come from? Cloudflare’s hardware system engineering team did a sensitivity analysis on three variants of 4th generation AMD EPYC processor to understand the contributing factors.
For the 4th generation AMD EPYC Processors, AMD offers three architectural variants:
mainstream classic Zen 4 cores, codenamed Continue reading

Protect against identity-based attacks by sharing Cloudflare user risk scores with Okta
Cloudflare One, our secure access service edge (SASE) platform, is introducing a new integration with Okta, the identity and access management (IAM) vendor, to share risk indicators in real-time and simplify how organizations can dynamically manage their security posture in response to changes across their environments.
For many organizations, it is becoming increasingly challenging and inefficient to adapt to risks across their growing attack surface. In particular, security teams struggle with multiple siloed tools that fail to share risk data effectively with each other, leading to excessive manual effort to extract signals from the noise. To address this complexity, Cloudflare launched risk posture management capabilities earlier this year to make it easier for organizations to accomplish three key jobs on one platform:
Evaluating risk posed by people by using first-party user entity and behavior analytics (UEBA) models
Exchanging risk telemetry with best-in-class security tools, and
Enforcing risk controls based on those dynamic first- and third-party risk scores.
Today’s announcement builds on these capabilities (particularly job #2) and our partnership with Okta by enabling organizations to share Cloudflare’s real-time user risk scores with Okta, which can then automatically enforce policies based on that user’s risk. In this way, organizations can adapt Continue reading
