Workers visibility: announcing Logpush for Worker’s Trace Events

Writing an application is like building a rocket. Countless hours in development and thousands of moving parts all come down to one moment - launch day. Picture the countdown: T minus 10 seconds. The entire team is making sure that things are running smoothly by monitoring dashboards that measure the health of every part of the system.

It’s every developer’s dream to get the level of visibility that NASA has in their mission control room, but for their own code. For flight directors and engineering directors alike, it’s important to have visibility into the systems that are built throughout development and after release. Today, we’re excited to announce Logpush for Worker’s Trace Events, making it easier than ever to gain visibility into applications built on Workers.

Workers Visibility Today

Today, we have lots of tools that are used to find out what’s happening in a Worker.

• Workers metrics & analytics
• Workers logs on the dashboard
• wrangler tail
• Observability Ecosystem Partners: Sentry, New Relic, Datadog

These tools are awesome for debugging, generalizing trends and monitoring Workers on third parties. They emphasize ease of use and make it effortless to get visibility quickly from your Workers.

As Workers have evolved, we’re Continue reading

A new era for Cloudflare Pages builds

Music is flowing through your headphones. Your hands are flying across the keyboard. You’re stringing together a masterpiece of code. The momentum is building up as you put on the finishing touches of your project. And at last, it’s ready for the world to see. Heart pounding with excitement and the feeling of victory, you push changes to the main branch…. only to end up waiting for the build to execute each step and spit out the build logs.

Starting afresh

Since the launch of Cloudflare Pages, there is no doubt that the build experience has been its biggest source of criticism. From the amount of waiting to inflexibility of CI workflow, Pages had a lot of opportunity for growth and improvement. With Pages, our North Star has always been designing a developer platform that fits right into your workflow and oozes simplicity. User pain points have been and always will be our priority, which is why today we are thrilled to share a list of exciting updates to our build times, logs and settings!

Over the last three quarters, we implemented a new build infrastructure that speeds up Pages builds, so you can iterate quickly and efficiently. In February, Continue reading

Introducing Direct Uploads for Cloudflare Pages

With Pages, we are constantly looking for ways to improve the developer experience. One of the areas we are keen to focus on is removing any barriers to entry for our users regardless of their use case or existing set up. Pages is an all-in-one solution with an automated Continuous Integration (CI) pipeline to help you build and deploy your site with one commit to your projects’ repositories hosted on GitHub or GitLab.

However, we realize that this excluded repositories that used a source control provider that Pages didn’t yet support and required varying build complexities. Even though Pages continues to build first-class integrations – for example, we added GitLab support in November 2021 – there are numerous providers to choose from, some of which use `git` alternatives like SVN or Mercurial for their version control systems. It’s also common for larger companies to self-host their project repositories, guarded by a mix of custom authentication and/or proxy protocols.

Pages needed a solution that worked regardless of the repository’s source location and accommodate build project’s complexity. Today, we’re thrilled to announce that Pages now supports direct uploads to give you more power to build and iterate how you want and with Continue reading

IPv6 Unique Local Addresses (ULA) Made Useless

Recent news from the Department of Unintended Consequences: RFC 6724 changed the IPv4/IPv6 source/destination address selection rules a decade ago, and it seems that the common interpretation of those rules makes IPv6 Unique Local Addresses (ULA) less preferred than the IPv4 addresses, at least according to the recent Unintended Operational Issues With ULA draft by Nick Buraglio, Chris Cummings and Russ White.

End result: If you use only ULA addresses in your dual-stack network¹, IPv6 won’t be used at all. Even worse, if you use ULA addresses together with global IPv6 addresses (GUA) as a fallback mechanism, there might be hidden gotchas that you won’t discover until you turn off IPv4. Looks like someone did a Truly Great Job, and ULA stands for Useless Local Addresses.

BGP Policy (Part 7)

At the most basic level, there are only three BGP policies: pushing traffic through a specific exit point; pulling traffic through a specific entry point; preventing a remote AS (more than one AS hop away) from transiting your AS to reach a specific destination. In this series I’m going to discuss different reasons for these kinds of policies, and different ways to implement them in interdomain BGP.

In this post—the last post in this series—I’m going to cover do not transit options from the perspective of AS65001 in the following network—

There are cases where an operator does not traffic to be forwarded to them through some specific AS, whether directly connected or multiple hops away. For instance, AS65001 and AS65005 might be operated by companies in politically unfriendly nations. In this case, AS65001 may be legally required to reject traffic that has passed through the nation in which AS65005 is located. There are at least three mechanisms in BGP that are used, in different situations, to enforce this kind of policy.

Do Not Advertise Communities (Provider Specific)

Many providers supply communities a customer can use to block the advertisement of their routes to a particular AS. For instance, if Continue reading

A Community Group for Web-interoperable JavaScript runtimes

Today, Cloudflare – in partnership with Vercel, Shopify, and individual core contributors to both Node.js and Deno – is announcing the establishment of a new Community Group focused on the interoperable implementation of standardized web APIs in non-web browser, JavaScript-based development environments.

The W3C and the Web Hypertext Application Technology Working Group (or WHATWG) have long pioneered the efforts to develop standardized APIs and features for the web as a development environment. APIs such as fetch(), ReadableStream and WritableStream, URL, URLPattern, TextEncoder, and more have become ubiquitous and valuable components of modern web development. However, the charters of these existing groups have always been explicitly limited to considering only the specific needs of web browsers, resulting in the development of standards that are not readily optimized for any environment that does not look exactly like a web browser. A good example of this effect is that some non-browser implementations of the Streams standard are an order of magnitude slower than the equivalent Node.js streams and Deno reader implementations due largely to how the API is specified in the standard.

Serverless environments such as Cloudflare Workers, or runtimes like Node.js and Deno, have Continue reading

Cloudflare and StackBlitz partner to deliver an instant and secure developer experience

We are starting our Platform Week focused on the most important aspect of a developer platform — developers. At the core of every announcement this week is developer experience. In other words, it doesn’t matter how groundbreaking the technology is if at the end of the day we’re not making your job as a developer easier.

Earlier today, we announced the general availability of a new Wrangler version, making it easier than ever to get started and develop with Workers. We’re also excited to announce that we’re partnering with StackBlitz. Together, we will bring the Wrangler experience closer to you – directly to your browser, with no dependencies required!

StackBlitz is a web-based code editor provided with a fresh and fast development environment on each page load. StackBlitz’s development environments are powered by WebContainers,  the first WebAssembly-based operating system, which boots secure development environments entirely within your browser tab.

Introducing new Wrangler, running in your browser

One of the Wrangler improvements we announced today is the option to easily run Wrangler in any Node.js environment, including your browser which is now powered by WebContainers!

StackBlitz’s WebContainers are optimized for starting any project within seconds, including the installation of Continue reading

10 things I love about Wrangler v2.0

Last November, we announced the beta release of a full rewrite of Wrangler, our CLI for building Cloudflare Workers. Since then, we’ve been working round the clock to make sure it's feature complete, bug-free, and easy to use. We are proud to announce that Wrangler goes public today for general usage, and can’t wait to see what people build with it!

Rewrites can be scary. Our goal for this version of Wrangler was backward compatibility with the original version, while significantly improving the developer experience. I'd like to take this opportunity to present 10 reasons why you should upgrade to the new Wrangler!

1. It's simpler to install:

Previously, folks would have to install @cloudflare/wrangler globally on a system. This made it hard to use different versions of Wrangler across projects. Further, it was hard to install on some CI systems because of lack of access to a user's root folder.  Sometimes, folks would forget to add the @cloudflare scope when installing, confusing them when a completely unrelated package was installed and didn't work as expected.

Let's fix that. We've simplified this by now publishing to the wrangler package, so you can run npm Continue reading

Continuous Detection and Mitigation (CDM)

Overview

What is CDM?

The CDM model

Ansible for security automation

Ansible for the CDM use case

Summary

Where to go next

Overview

Per NASCIO, the top priority for state CIOs is cybersecurity and risk management. A key focus for this initiative is to leverage the Continuous Diagnostics and Mitigation (CDM) framework provided by the Cybersecurity and Infrastructure Security Agency (CISA). In this blog post we will explore a high level view of the CDM framework, review Ansible’s role in security automation and finally understand how Ansible can help agencies with Day 0 through Day 2 tasks while working with the CDM framework.

What is CDM?

Today more than ever, cyber threats mean that securing and defending our networks are of utmost importance. A recent report published by the National League of Cities revealed that an astonishing 44% of local governments report they experience a cyberattack daily or even hourly. So it is not surprising to see that cybersecurity and risk management is the number one priority for our state CIOs. With that background, let’s understand the CDM program.
