Server-side render full stack applications with Pages Functions

Pages Functions are now out of beta and generally available, bringing dynamic computation within 50ms of 95% of users globally. Built on top of Cloudflare Workers, Pages projects are easy to deploy and instantly benefit from this low latency, with over 275 data centers across the globe.

With Page Functions comes the ability to add dynamic server-side rendering to your applications. Pages makes it easy to deploy applications built using all the major meta-frameworks such as Astro, Next.js, Qwik, Remix, Solid, and Svelte. There is no better time to start deploying your server-side rendered full-stack applications to Cloudflare Pages.

Go server-side with Pages Functions

When Pages launched in December 2020, it was focused on being a high-performance host for static assets. Pages was a perfect choice for anyone building websites which could be generated ahead of time with static site generation. Jamstack was all the rage, and Cloudflare's network was an excellent choice for its ability to serve static files to visitors from around the globe.

Once deployed the files would be effortlessly hosted and served at incredible speeds across the world to your users. These statically generated applications can run client-side code in the browser to Continue reading

How Cloudflare uses Terraform to manage Cloudflare

Configuration management is far from a solved problem. As organizations scale beyond a handful of administrators, having a secure, auditable, and self-service way of updating system settings becomes invaluable. Managing a Cloudflare account is no different. With dozens of products and hundreds of API endpoints, keeping track of current configuration and making bulk updates across multiple zones can be a challenge. While the Cloudflare Dashboard is great for analytics and feature exploration, any changes that could potentially impact users really should get a code review before being applied!

This is where Cloudflare's Terraform provider can come in handy. Built as a layer on top of the cloudflare-go library, the provider allows users to interface with the Cloudflare API using stateful Terraform resource declarations. Not only do we actively support this provider for customers, we make extensive use of it internally! In this post, we hope to provide some best practices we've learned about managing complex Cloudflare configurations in Terraform.

Why Terraform

Unsurprisingly, we find Cloudflare's products to be pretty useful for securing and enhancing the performance of services we deploy internally. We use DNS, WAF, Zero Trust, Email Security, Workers, and all manner of Continue reading

The most programmable Supercloud with Cloudflare Snippets

Your traffic, how you like it

Cloudflare is used by a highly diverse customer base. We offer simple-to-use products for everything from setting HTTP headers to rewriting the URI path and performing URL redirects. Sometimes customers need more than the out-of-the-box functionality, not just adding an HTTP header - but performing some advanced calculation to create the output. Today they would need to create a feature request and wait for it to be shipped, write a Cloudflare Worker, or keep this modification ‘on origin’ - on their own infrastructure.

To simplify this, we are delighted to announce Cloudflare Snippets. Snippets are a new way to perform traffic modifications that users either cannot do via our productised offerings, or want to do programmatically. The best part? The vast majority of customers will pay nothing extra for using Snippets.

Users now have a choice. Perform the action via a rule. Or, if more functionality is needed, write a Snippet. Neither will mean waiting. Neither will incur additional cost (although a high fair usage cap will apply). Snippets unblocks users to do what they want, when they want. All on Cloudflare.

Snippets will support the import of code written in various languages, Continue reading

Keep track of Workers’ code and configuration changes with Deployments

Today we’re happy to introduce Deployments for Workers. Deployments allow developers to keep track of changes to their Worker; not just the code, but the configuration and bindings as well. With deployments, developers now have access to a powerful audit log of changes to their production applications.

And tracking changes is just the beginning! Deployments provide a strong foundation to add: automated deployments, rollbacks, and integration with version control.

Today we’ll dive into the details of deployments, how you can use them, and what we’re thinking about next.

Deployments

Deployments are a powerful new way to track changes to your Workers. With them, you can track who’s making changes to your Workers, where those changes are coming from, and when those changes are being made.

Cloudflare reports on deployments made from wrangler, API, dashboard, or Terraform anytime you make changes to your Worker’s code, edit resource bindings and environment variables, or modify configuration like name or usage model.

We expose the source of your deployments, so you can track where changes are coming from. For example, if you have a CI job that’s responsible for changes, and you see a user made a change through the Cloudflare dashboard, it’s easy Continue reading

Ways to look at logged in users on Linux

There are quite a few ways on Linux to get a list of the users logged into the system and see what they are doing. The commands described in this article all provide very useful information.users The users command displays a simple list of logged-in users. In this example, one user is logged in twice and is, therefore, listed twice.$ users nemo popeye shs shs Note that the users are listed in alphabetical order.who The who command provides additional information. The login terminal is identified along with the login date and time. The final field displays the terminal or the IP address of the connecting system.To read this article in full, please click here

Multihoming Cannot Be Solved within a Network

Henk made an interesting comment that finally triggered me to organize my thoughts about network-level host multihoming¹:

The problems I see with routing are: [hard stuff], host multihoming, [even more hard stuff]. To solve some of those, we should have true identifier/locator separation. Not an after-thought like LISP, but something built into the layer-3 addressing architecture.

Proponents of various clean-slate (RINA) and pimp-my-Internet (LISP) approaches are quick to point out how their solution solves multihoming. I might be missing something, but it seems like that problem cannot be solved within the network.

Networking for remote work puts the emphasis on people, not sites

Many companies had to support work-from-home (WFH) during COVID, and most looked forward to having their staff back in the office. Most now tell me that some or all of the staff isn’t coming back, and that remote work is a given for at least some positions, likely for a very long time. That’s opened major questions about how these now-forever-roaming workers are connected to information resources and to each other.Didn’t we solve this already, with Zoom and Teams? Sort of. Collaborative video applications provide a reasonable substitute for meetings, but you still have the challenge of application access and information delivery. A bit over 80% of enterprises I’ve talked with say they need to make a remote worker look like they’re at their desk, and they need to be able to work as though they were as well.To read this article in full, please click here
