A single dashboard for Cloudflare for Teams

A single dashboard for Cloudflare for Teams

Starting today, Cloudflare Access can now be used in the Cloudflare for Teams dashboard. You can manage security policies for your people and devices in the same place that you build zero-trust rules to protect your applications and resources. Everything is now in one place in a single dashboard.

We are excited to launch a new UI that can be used across the entire Teams platform, but we didn’t build this dashboard just for the sake of a new look-and-feel. While migrating the Access dashboard, we focused on solving one of the largest sources of user confusion in the product.

This post breaks down why the original  UI caused some headaches, how we think about objects in Cloudflare for Teams, and how we set out to fix the way we display that to our users.

Cloudflare Access

Cloudflare Access is one-half of Cloudflare for Teams, a security platform that runs on Cloudflare’s network. Teams protects users, devices and data  without compromising experience or performance. We built Cloudflare Access to solve our own headaches with private networks as we grew from a team concentrated in a single office to a globally distributed organization.

Introducing: The AWX Collection

Ansible Content Collections are a new way of distributing content, including modules, for Ansible. For detailed information on how to use collections in general, please read Colin McNaughton’s blog post about the topic.  

The AWX Collection allows Ansible Playbooks to interact with AWX and Ansible Tower. Much like interacting with AWX or Red Hat Ansible Tower via the web-based UI or the API, the modules provided by the AWX Collection are another way to create, update or delete objects as well as perform tasks such as run jobs, configure Ansible Tower and more. This article will discuss new updates regarding this collection, as well as an example playbook and details on how to run it successfully.

The AWX Collection awx.awx is the upstream community distribution available on Ansible Galaxy.  The downstream supported Ansible Collection ansible.tower is being targeted for mid-May on Automation Hub alongside the release of Ansible Tower 3.7.  For more details on the difference between Ansible Galaxy and Automation Hub please refer to Ajay Chenampara’s blog post.

This collection is a replacement for the Ansible Tower web modules which were previously housed and maintained directly in the Ansible repo. The modules were Continue reading

Key Factors in Attracting and Retaining Talent

Yesterday I posted a tweet on company culture that received a lot of positive feedback:

People thought this should be saved in a blog post, so this is it.

Company Culture

Do you want to attract and retain talent and high performers? Of course you do. Do you understand how to do that and are you willing to change your company culture?

Everything starts with culture. You may have heard the quote “Culture eats strategy for breakfast”, meaning that even the best stratety can’t compete with a company that has a great culture. Strategy without culture does not create success.

Gimmicks Are Not Culture

Most companies, such as the web scalers, often confuse gimmicks with culture. We have great company culture! We have ping pong tables, flipper games and even artists who play music for us! While these things can be entertaining, don’t mistake them for culture. Continue reading

The Week in Internet News: Classroom in a Car

Searching for a signal: CNN has a story about a teacher in rural Virginia who drives 20 minutes to find a good WiFi signal in order to work. The middle school history teacher is one of about 18 million U.S. residents who lack access to high-speed broadband, according to the Federal Communications Commission. The teacher “lives in a valley between two mountains, where the only available home internet option is a satellite connection. Her emails can take 30 seconds to load, only to quit mid-message. She can’t even open files on Google Drive, let alone upload lesson modules or get on a Zoom call with colleagues.”

Demanding access: Meanwhile, in Oakland, California, hundreds of teachers and students are calling for free access to the Internet, demanding that the school district and mayor “take all necessary measures” to ensure that students have access, KTVU reports. “There is no equity in education for our most vulnerable students if all Oakland families do not have access to the internet,” said Keith Brown, president of the Oakland Education Association, said.

Explore: BGP in Data Center Fabrics

Got mentioned in this tweet a while ago:

Watching @ApstraInc youtube stream regarding BGP in the DC with @doyleassoc and @jtantsura.Maybe BGP is getting bigger and bigger traction from big enterprise data centers but I still see an IGP being used frequently. I am eager to have @ioshints opinion on that hot subject.

Maybe I’ve missed some breaking news, but assuming I haven’t my opinion on that subject hasn’t changed.

Getting Started with Cluster API using Docker

Cluster API (CAPI) is a relatively new project aimed at deploying Kubernetes clusters using a declarative API (think YAML). The official documentation (a.k.a. the Cluster API book), does a very good job explaining the main concepts and goals of the project. I always find that one of the best ways to explore new technology is to see how it works locally, on my laptop, and Cluster API has a special “Docker” infrastructure provider (CAPD) specifically for that. However, the official documentation for how to setup a docker managed cluster is very poor and fractured. In this post, I’ll try to demonstrate the complete journey to deploy a single CAPI-managed k8s cluster and provide some explanation of what happens behind the scene so that its easier to troubleshoot when things go wrong.

Prerequisites

Two things must be pre-installed before we can start building our test clusters:

  • kind - a tool to setup k8s clusters in docker containers, it will be used as a management (a.k.a. bootstrap) cluster.
  • clusterctl - a command line tool to interact with the management cluster.

We’re gonna need run a few scripts from the Cluster API Github repo, so let’s get a copy Continue reading

Our Work to Make the Internet for Everyone Marches On

PIR and ISOC logos

Over the past several months the Internet Society has been working on a transaction to sell Public Interest Registry (PIR), operator of .ORG and other top-level domains, to Ethos Capital. Under PIR’s registry agreements, the Internet Corporation for Assigned Names and Numbers (ICANN) had to consent to this indirect change of control. ICANN has now announced that it does not consent to the transaction. 

I am, of course, disappointed by ICANN’s decision, though I am pleased it was finally reached. ICANN took much longer than it should have done to vote on the transaction. In my view, ICANN stepped outside its remit by acting as a regulator it was never intended to be.  What began as a routine change of indirect control – the type ICANN has expeditiously approved on multiple occasions in the past – resulted in months and months of review and analysis. The outcome does not seem consistent with ICANN’s prior decisions in similar cases. It should concern  the Internet community that ICANN has shown itself to be much more susceptible to political pressure than its limited mandate would recommend.

Nevertheless, ICANN has now rendered a clear decision. This brings to a close a period Continue reading
