How to secure Generative AI applications

I remember when the first iPhone was announced in 2007. This was NOT an iPhone as we think of one today. It had warts. A lot of warts. It couldn’t do MMS for example. But I remember the possibility it brought to mind. No product before had seemed like anything more than a product. The iPhone, or more the potential that the iPhone hinted at, had an actual impact on me. It changed my thinking about what could be.

In the years since no other product came close to matching that level of awe and wonder. That changed in March of this year. The release of GPT-4 had the same impact I remember from the iPhone launch. It’s still early, but it's opened the imagination, and fears, of millions of developers in a way I haven’t seen since that iPhone announcement.

That excitement has led to an explosion of development and hundreds of new tools broadly grouped into a category we call generative AI. Generative AI systems create content mimicking a particular style. New images that look like Banksy or lyrics that sound like Taylor Swift. All of these Generative AI tools, whether built on top of GPT-4 or something Continue reading

Building Cloudflare on Cloudflare

Cloudflare’s website, application security and performance products handle upwards of 46 million HTTP requests per second, every second. These products were originally built as a set of native Linux services, but we’re increasingly building parts of the system using our Cloudflare Workers developer platform to make these products faster, more robust, and easier to develop. This blog post digs into how and why we’re doing this.

System architecture

Our architecture can best be thought of as a chain of proxies, each communicating over HTTP. At first, these proxies were all implemented based on NGINX and Lua, but in recent years many of them have been replaced - often by new services built in Rust, such as Pingora.

The proxies each have distinct purposes - some obvious, some less so. One which we’ll be discussing in more detail is the FL service, which performs “Front Line” processing of requests, applying customer configuration to decide how to handle and route the request.

This architecture has worked well for more than a decade. It allows parts of the system to be developed and deployed independently, parts of the system to be scaled independently, and traffic to be routed to different nodes in Continue reading

How Cloudflare is powering the next generation of platforms with Workers

We launched Workers for Platforms, our Workers offering for SaaS businesses, almost exactly one year ago to the date! We’ve seen a wide array of customers using Workers for Platforms – from e-commerce to CMS, low-code/no-code platforms and also a new wave of AI businesses running tailored inference models for their end customers!

Let’s take a look back and recap why we built Workers for Platforms, show you some of the most interesting problems our customers have been solving and share new features that are now available!

What is Workers for Platforms?

SaaS businesses are all too familiar with the never ending need to keep up with their users' feature requests. Thinking back, the introduction of Workers at Cloudflare was to solve this very pain point. Workers gave our customers the power to program our network to meet their specific requirements!

Need to implement complex load balancing across many origins? Write a Worker. Want a custom set of WAF rules for each region your business operates in? Go crazy, write a Worker.

We heard the same themes coming up with our customers – which is why we partnered with early customers to build Workers for Platforms. We worked with the Continue reading

Find the Optimal Level of Automation Abstraction

Tom Ammon sent me his thoughts on choosing the right level of abstraction in your network automation solution as a response to my What Is Intent-Based Networking blog post, and allowed me to publish them on ipspace.net.

I totally agree with your what vs how example with OSPF. I work on a NOS team where if we wanted, we could say, instead of “run OSPF on these links”, do this:

Kubernetes network security foundations: Get started on building your Kubernetes network security policies with Calico!

The adoption of cloud native applications has become a necessity for organizations to run their businesses efficiently. As per Gartner, more than 85% of organizations will embrace a cloud-first principle by 2025, which will rely on adopting cloud native applications for complete execution. The massive increase in adoption of cloud native applications has given rise to more security challenges such as container image vulnerabilities, configuration errors and a larger runtime attack surface. Kubernetes has become the de facto standard platform to host and run cloud native applications. However, as Kubernetes adoption gains momentum, so does the security risk associated with business-critical applications that communicate with multiple external and internal systems. Kubernetes network security is a critical aspect of securing cloud native applications and the Kubernetes platform itself. This multi-part blog series aims to explore the network security challenges of the Kubernetes environment and provide insights into mitigating them using Calico security controls. The series will cover various aspects of network security, including security policies, application layer security, host network security, Pod traffic encryption, and the importance of a defense-in-depth security approach. Let’s dive into the world of Kubernetes network security and learn how to protect your organization’s valuable assets.

Startup NEO Semiconductor promises 8x increase in memory density

System memory is a complex problem. More memory means more performance, especially in a virtualized environment. But more memory also requires more power, and that can add up as you start to get into thousands of memory sticks.Plus, you can only put so many memory sticks in a server, depending on the number of slots available. So how do you increase memory capacity? By increasing memory density on the chips, which is easier said than done. However, a startup called NEO Semiconductor is claiming it will be able to increase memory density by up to eight times over standard memory with a breakthrough 3D design.It’s not a new concept; 3D memory stacking has been used in NAND flash to increase capacity for a decade now. Memory transistors can only be so large to fit in the confines of a DRAM chip. Rather than an increase the number of transistors laid out side by side, memory makers began stacking it on top of each other, thus increasing capacity in the same physical space. In the 10 years since 3D stacking began, NAND flash DRAM has reached the 170-layer mark, and SSDs have seen a significant increase in capacity without Continue reading

Making Cloudflare the best place for your web applications

Hey web developers! We are about to shake things up a bit here at Cloudflare and wanted to give you a heads-up, so that you know what we are doing and where we are going. You might know Cloudflare as one of the best places to come to when you need to protect, speed up, or scale your web application, but increasingly Cloudflare is also becoming the best place to deploy and run your application!

Why deploy your application to Cloudflare? Two simple reasons. First, it removes lots of hassle of managing many separate systems and allows you to develop, deploy, monitor, and tune your application all in one place. Second, by deploying to Cloudflare directly, there is so much more we can do to optimize your application and get it to the hands, ears, or eyes of your users more quickly and smoothly.

So what’s changing? Quite a bit, actually. I’m not going to bore you with rehashing all the details as my most-awesome colleagues have written separate blog posts with all the details, but here is a high level rundown.

Cloudflare Workers + Pages = awesome development platform

Cloudflare Pages and Workers are merging into a single unified Continue reading

A whole new Quick Edit in Cloudflare Workers

Quick Edit is a development experience for Cloudflare Workers, embedded right within the Cloudflare dashboard. It’s the fastest way to get up and running with a new worker, and lets you quickly preview and deploy changes to your code.

We’ve spent a lot of recent time working on upgrading the local development experience to be as useful as possible, but the Quick Edit experience for editing Workers has stagnated since the release of workers.dev. It’s time to give Quick Edit some love and bring it up to scratch with the expectations of today's developers.

Before diving into what’s changed—a quick overview of the current Quick Edit experience:

We used the robust Monaco editor, which took us pretty far—it’s even what VSCode uses under the hood! However, Monaco is fairly limited in what it can do. Developers are used to the full power of their local development environment, with advanced IntelliSense support and all the power of a full-fledged IDE. Compared to that, a single file text editor is a step-down in expressiveness and functionality.

VSCode for Web

Today, we’re rolling out a new Quick Edit experience for Workers, powered by VSCode for Web. This is a huge Continue reading
