Debug Queues from the dash: send, list, and ack messages
Today, August 11, 2023, we are excited to announce a new debugging workflow for Cloudflare Queues. Customers using Cloudflare Queues can now send, list, and acknowledge messages directly from the Cloudflare dashboard, enabling a more user-friendly way to interact with Queues. Though it can be difficult to debug asynchronous systems, it’s now easy to examine a queue’s state and test the full flow of information through a queue.
With guaranteed delivery, message batching, consumer concurrency, and more, Cloudflare Queues is a powerful tool to connect services reliably and efficiently. Queues integrate deeply with the existing Cloudflare Workers ecosystem, so developers can also leverage our many other products and services. Queues can be bound to producer Workers, which allow Workers to send messages to a queue, and to consumer Workers, which pull messages from the queue.
We’ve received feedback that while Queues are effective and performant, customers find it hard to debug them. After a message is sent to a queue from a producer worker, there’s no way to inspect the queue’s contents without a consumer worker. The limited transparency was frustrating, and the need to write a skeleton worker just to debug a queue was high-friction.

Introducing scheduled deletion for Cloudflare Stream
Designed with developers in mind, Cloudflare Stream provides a seamless, integrated workflow that simplifies video streaming for creators and platforms alike. With features like Stream Live and creator management, customers have been looking for ways to streamline storage management.
Today, August 11, 2023, Cloudflare Stream is introducing scheduled deletion to easily manage video lifecycles from the Stream dashboard or our API, saving time and reducing storage-related costs. Whether you need to retain recordings from a live stream for only a limited time, or preserve direct creator videos for a set duration, scheduled deletion will simplify storage management and reduce costs.
Stream scheduled deletion
Scheduled deletion allows developers to automatically remove on-demand videos and live recordings from their library at a specified time. Live inputs can be set up with a deletion rule, ensuring that all recordings from the input will have a scheduled deletion date upon completion of the stream.
Let’s see how it works in those two configurations.
Getting started with scheduled deletion for on-demand videos
Whether you run a learning platform where students can upload videos for review, a platform that allows gamers to share clips of their gameplay, or anything in between, scheduled deletion can help Continue reading
Software Is Everywhere
"Software is eating the world." Have truer words ever been spoken other than these words by Marc Andreessen?
I've recently been immersed in a number of home automation projects (lights, heating/cooling, presence detection, and more). I was reflecting on what made all of these automations possible: the drastic increase in the amount of software present in the home. As I was reflecting on this, I realized how different my house is in this respect compared to the house I grew up in.
Now, I'm not saying I'm old. More like, the rate of digitization in the world around us has happened at such a pace that even in my short lifetime, the changes have been deep and wide.
This blog post is a tour of things in my house that are software operated that were not software operated in the house I grew up in. For my purposes here, I define "software operated" as any device that has software or firmware that is upgradable either by me or through an over-the-air process that the device or its cloud service initiates. I'm leaving out "obvious" items like laptops, tablets, and mobile phones.

IPv6 Buzz 132: Down The Rabbit Hole Of IPv6 Router Advertisements

Before diving into a new technology, it is always useful to understand the previous generation of technology, what the limitations where, and how the new technology intends to overcome them. In this post, let’s look at what some of the challenges were with L2-based networks and how VXLAN/EVPN can overcome them. Before starting, I want to balance the messaging a bit on the bad reputation that STP gets:
- Radia Perlman did an excellent job with what was available at that time.
- A lot of the bad reputation comes from a misunderstanding of the protocol.
- STP-based networks can run just fine but they are often misconfigured (related to the point above).
- Many issues come from misbehaving end user devices where protection mechanisms have not been implemented (see the point above).
- It’s natural for technologies to evolve as more compute becomes available and we gain experience.
Keep in mind that the original 802.1D standard was published in 1990. This was long before internet was generally available and our networks were critically important to us. At that time we didn’t measure outages in seconds or even minutes. That said, let’s look at the limitations of a traditional L2 network.

Automated namespace isolation with Calico
Calico has recently introduced a powerful new policy recommendation engine that enables DevOps, SREs, and Kubernetes operators to automatically generate Calico policies to implement namespace isolation and improve the security posture of their clusters.
This new recommendation engine is unique for three reasons:
- Calico’s policy recommendations work continuously in the background over a user-configurable time period. This ensures that less frequent traffic flows are also accounted for in recommended policies.
- Policy recommendations leverage Calico’s policy tiers. Tiers enforce an order of precedence on how Calico policies are evaluated and enforced. The recommended policies are placed in their own tier and Calico ensures each generated rule does not conflict with other policies you have implemented.
- Recommended policies are
StagedNetworkPolicies, allowing admins and operators to audit the behavior of these security policies before actively enforcing them.
In this blog, we’ll dive into each of these areas in more detail and provide an in-depth overview of how policy recommendations work and how it can improve the security posture of your cluster.
Before we get started, let’s quickly talk about namespace isolation and why it’s so important.
Why is namespace isolation important?
Namespaces are a foundational concept within Kubernetes. They help divide your Continue reading
Day Two Cloud 206: Making The Most Of Red Teaming With Gemma Moore
Red teams attack a customer's security systems. The idea of a red team, whether consultants or in-house, is to approach the target like an attacker would. A red team includes technical and human-based exploit and attempts to test defenses, probe for weaknesses, and identify vulnerable systems and processes. On today's episode we look at how to get the most out of a red team engagement--it's much more than just an attack and a report.
