Introducing Cache Reserve: massively extending Cloudflare’s cache

One hundred percent. 100%. One-zero-zero. That’s the cache ratio we’re all chasing. Having a high cache ratio means that more of a website’s content is served from a Cloudflare data center close to where a visitor is requesting the website. Serving content from Cloudflare’s cache means it loads faster for visitors, saves website operators money on egress fees from origins, and provides multiple layers of resiliency and protection to make sure that content is reliably available to be served.

Today, I’m delighted to announce a massive extension of the benefits of caching with Cache Reserve: a new way to persistently serve all static content from Cloudflare’s global cache. By using Cache Reserve, customers can see higher cache hit ratios and lower egress bills.

Why is getting a 100% cache ratio difficult?

Every second, Cloudflare serves tens-of-millions of requests from our cache which equates to multiple terabytes-per-second of cached data being delivered to website visitors around the world. With this massive scale, we must ensure that the most requested content is cached in the areas where it is most popular. Otherwise, visitors might wait too long for content to be delivered from farther away and our network would be running inefficiently. Continue reading

Logs on R2: slash your logging costs

Logs on R2: slash your logging costs
Logs on R2: slash your logging costs

Hot on the heels of the R2 open beta announcement, we’re excited that Cloudflare enterprise customers can now use Logpush to store logs on R2!

Raw logs from our products are used by our customers for debugging performance issues, to investigate security incidents, to keep up security standards for compliance and much more. You shouldn’t have to make tradeoffs between keeping logs that you need and managing tight budgets. With R2’s low costs, we’re making this decision easier for our customers!

Getting into the numbers

Cloudflare helps customers at different levels of scale — from a few requests per day, up to a million requests per second. Because of this, the cost of log storage also varies widely. For customers with higher-traffic websites, log storage costs can grow large, quickly.

As an example, imagine a website that gets 100,000 requests per second. This site would generate about 9.2 TB of HTTP request logs per day, or 850 GB/day after gzip compression. Over a month, you’ll be storing about 26 TB (compressed) of HTTP logs.

For a typical use case, imagine that you write and read the data exactly once – for example, you might write the data to Continue reading

Durable Objects Alarms — a wake-up call for your applications

Durable Objects Alarms — a wake-up call for your applications
Durable Objects Alarms — a wake-up call for your applications

Since we launched Durable Objects, developers have leveraged them as a novel building block for distributed applications.

Durable Objects provide globally unique instances of a JavaScript class a developer writes, accessed via a unique ID. The Durable Object associated with each ID implements some fundamental component of an application — a banking application might have a Durable Object representing each bank account, for example. The bank account object would then expose methods for incrementing a balance, transferring money or any other actions that the application needs to do on the bank account.

Durable Objects work well as a stateful backend for applications — while Workers can instantiate a new instance of your code in any of Cloudflare’s data centers in response to a request, Durable Objects guarantee that all requests for a given Durable Object will reach the same instance on Cloudflare’s network.

Each Durable Object is single-threaded and has access to a stateful storage API, making it easy to build consistent and highly-available distributed applications on top of them.

This system makes distributed systems’ development easier — we’ve seen some impressive applications launched atop Durable Objects, from collaborative whiteboarding tools to conflict-free replicated data type (CRDT) systems for coordinating Continue reading

6 top network security threats and how to beat them

It's a war zone out there. In the seemingly endless game of cyber cat and mouse, accurate intelligence remains the best tool for beating attackers at their own game.Here's an analysis of today's six top network threats and tips for how to identify and quash them.1. Ransomware Ransomware is easily the greatest network threat, since it gives attackers the biggest bang for the buck with a relatively low probability of getting caught. "There's also a low bar in the skill category to break into this sort of thing," says Andy Rogers, a senior assessor at cybersecurity and compliance firm Schellman. "There are plenty of Ransomware-as-a-Service (RaaS) businesses that will be more than willing to ensure you have the tools you need to unleash a ransomware campaign."To read this article in full, please click here

Watching Eurovision 2022 on Cloudflare Radar

The Eurovision Song Contest has a history that goes back to 1956, so it's even older than the European Union and one of its highlights over the years was being the first global stage for the Swedish group ABBA — Waterloo won the 1974 edition). This year, for the 66th edition, we have a dedicated page for Eurovision fans, journalists or anyone interested in following Internet trends related to the event taking place in Turin, Italy.

The contest consists of two semi-finals and a final. The first semi-final is today, May 10, at 21:00 CEST, the second is Thursday, May 12, at 21:00 CEST. And the final is on Saturday, May 14, at 21:00 CEST. We are using Central European Summer Time and not our usual (on Radar) UTC because that’s the timezone of most of the 40 countries that will take part in the contest. There will be 17 countries in the first semi-final, 18 in the second, and 25 in the final (the full list is here).

From countries to fan sites.

First, you can see the Internet traffic aggregate in all the 40 countries that are participating in Eurovision 2022. There’s also a Continue reading

Introducing a brand new way to automate your Azure Cloud

In December of 2021, Red Hat and Microsoft announced the Red Hat Ansible Automation Platform on Microsoft Azure. 

This year during Red Hat Summit 2022, Red Hat announced the General Availability of the Red Hat Ansible Automation Platform on Microsoft Azure in North America with global availability coming soon.  

I’d like to spend some time providing some more details about this offering and why you should be considering Ansible Automation Platform on Azure.



Azure Marketplace deployment

Ansible Automation Platform on Azure (AAP on Azure) deploys from the Azure Marketplace as a managed application.  It deploys directly into your Azure Subscription, but Red Hat as the publisher of the application has access to a shared and secured managed resource group to support, maintain, and upgrade your deployment. More specifically, a dedicated Red Hat SRE team deals with all the ongoing management of AAP on Azure, while you focus on expanding your automation strategy within your organization across the hybrid cloud.

 

 

Azure Integrations

For many organizations using Azure today, there’s a huge benefit in taking advantage of AAP on Azure.  It runs in your Azure subscription.  It integrates seamlessly with many of the Azure services, Continue reading

Announcing Workers for Platforms: making every application on the Internet more programmable

As a business, whether a startup or Fortune 500 company, your number one priority is to make your customers happy and successful with your product. To your customers, however, success and happiness sometimes seems to be just one feature away.

“If only you could customize X, we’ll be able to use your product” - the largest prospect in your pipeline. “If you just let us do Y,  we’ll expand our usage of your product by 10x” - your most strategic existing customer.

You want your product to be everything to everybody, but engineering can only keep up so quickly, so, what gives?

Today, we’re announcing Workers for Platforms, our tool suite to help make any product programmable, and help our customers deliver value to their customers and developers instantaneously.

A more programmable interface

One way to give your customers the ability to programmatically interact with your product is by providing them with APIs. That is a big part of why APIs are so prolific today — enabling code (whether your own, or that of a 3rd party) to engage with your applications is nothing short of revolutionary.

But there’s still a problem. While APIs can give developers the ability Continue reading
