Location-based personalization at the edge with Cloudflare Workers

We’re excited to announce an update to Cloudflare Workers, our serverless code platform built on our global network. Geolocation data is now accessible and free for all developers on our Workers platform, including users on the free plan!

You can now serve personalized experiences for users based on their location using Workers. Personalization is critical to building intuitive apps for users and it unlocks new possibilities for what you can build on our platform. Whether you’re building a social networking app or an automatic shipping cost estimator for an e-commerce site, a one-size-fits-all experience doesn’t cut it. Location-based personalization helps you show what’s most relevant to your users, be it tickets for movies in their area or content in their local language.

With geolocation data available on the server side, there’s no configuration needed for users to set their location.

Each request to a Worker includes the user’s (example data shown):

• Country: “US”
• City: “Austin”
• Continent: “NA”
• Latitude: "30.27130"
• Longitude: “-97.74260”
• Postal code: "78701"
• Metro code(dma): “635”
• Region: “Texas”
• Timezone: “America/Chicago”

Geolocation data on Workers makes it even easier to build server rendered apps and customized services.

Expanding the Cloudflare Workers Observability Ecosystem

One of the themes of Developer Week is “it takes a village”, and observability is one area where that is especially true. Cloudflare Workers lets you quickly write code that is infinitely scalable — no availability regions, no scaling policies. Your code runs in every one of our data centers by default: region Earth, as we like to say. While fast time to market and effortless scale are amazing benefits, seasoned developers know that as soon as your code is in the wild… stuff happens, and you need the tools in place to investigate, diagnose, fix and monitor those issues.

Today we’re delighted to add to our existing analytics partners. We’re announcing new partnerships with six observability-focused companies that are deeply integrated into the Cloudflare Workers ecosystem. We’re confident these partnerships will provide immediate value in building the operational muscle to maintain and make your next generation of applications fast, secure and bullet-proof in production.

console.log(`Got request. Extracted name=${name}. Saving…`);

Cloudflare wrangler gives you the ability to generate, configure, build, preview and publish your projects, from the comfort of your dev environment. Writing code in your favorite IDE with a fully-fledged CLI tool that also allows you to simulate Continue reading

10 of the best ways to get help on Linux

Just because Linux appeals to the nerdiest of nerds doesn't mean that it can't be extremely helpful for those who don't want to spend a lot of time delving into the technical details of how to use various commands. In fact, Linux provides a series of tools that can help anyone master the command line or just get the task at hand done more quickly and efficiently. This post covers 10 of the best options.man pages You can always go to the man pages to answer usage and syntax questions you might have on a Linux command. Just type "man" followed by the name of the command (e.g., man ps), and you'll get a lot of descriptive information. On the other hand, if you really just want to see some examples of how to use a particular command, the content of a man page might be a lot more than you want to comb through. In the remainder of this post, I'll explain some other options for finding the command that you need and learning how to use it.To read this article in full, please click here

Must Read: Automate Nexus-OS Fabric Deployment

Some networking engineers breeze through our Network Automation online course, others disappear after a while… and a few of those come back years later with a spectacular production-grade solution.

Stephen Harding is one of those. He attended the automation course in spring 2019 and I haven’t heard from him in almost two years… until he submitted one of the most mature data center fabric automation solutions I’ve seen.

Not only that, he documented the solution in a long series of must-read blog posts. Hope you’ll find them useful; I liked them so much I immediately saved them to Internet Archive (just in case).

Nvidia announces a 2023 launch for an HPC CPU named Grace

Nvidia kicked off its GPU Technology Conference (GTC) 2021 with a bang: A new CPU for high performance computing (HPC) clients--its first-ever data-center CPU--called Grace.Based on the Arm Neoverse architecture, NVIDIA claims Grace will serve up to 10-times better performance than the fastest servers currently on the market for complex artificial intelligence and HPC workloads.But that’s comparing then and now. Grace won’t ship until 2023, and in those two years competitors will undoubtedly up their game, too. But no one has ever accused CEO Jen-Hsun Huang of being subdued.Nvidia made a point that Grace is not intended to compete head-to-head against Intel's Xeon and AMD's EPYC processors. Instead, Grace is more of a niche product, in that it is designed specifically to be tightly coupled with NVIDIA's GPUs to remove bottlenecks for complex AI and HPC applications.To read this article in full, please click here

Automating a RHEL 8 Installation Using the VMware REST Ansible Collection

Managing virtual machines in an IT infrastructure is often a common task, specifically VMware virtualization technology has been around for over 20 years. VMware administrators spend a lot of their time in automating the creation, management, and removal of virtual instances that contain various operating systems. One operating system that often resides on VMware infrastructure is Red Hat Enterprise Linux. 

With the introduction of VMware REST APIs, we recently announced the initial release of the vmware.vmware_rest Collection, for production use. As opposed to the community.vmware Collection, the vmware.vmware_rest Collection is based on next generation VMware REST APIs.  This new Collection no longer requires any third party Python bindings to communicate with VMware infrastructure. A large part of the new Collection that has been introduced is support for automating virtual machine operations.

In this blog post I will show you how VMware users can automate the installation of Red Hat Enterprise Linux 8 (RHEL 8) using the vmware.vmware_rest.vcenter_vm module and a valid Kickstart file.

 

Scenario requirements

For this scenario, we will assume following requirements:

1. vCenter 7.0.1 or latest with at least one ESXi 
2. RHEL 8 installation DVD
3. Ansible
4. vmware.vmware_rest Continue reading

4 Data Center Security Issues That Will Make You Rethink Firewalling

Recall what was happening a decade ago? While 2011 doesn’t seem that long ago (you remember, the Royal Wedding, Kim Kardashian’s divorce, and of course Charlie Sheen’s infamous meltdown), a lot has changed in 10 years. Back then, most data centers were just starting to experiment with virtualization. Remember when it was considered safe for only a handful of non-essential workloads to go virtual? Well, today about half of the servers globally have become virtualized, and we’ve moved well beyond just virtualization. Nearly every enterprise data center has become a hybrid environment, with a mix of physical and virtual storage and compute resources. Containerization and the technologies supporting it are starting to take hold. And of course, cloud computing has become pervasive in all aspects of enterprise computing. 

Now, the business benefits of today’s software-defined data center are many, especially in terms of resource efficiency and cost savings. But there’s no denying that complexity has also increased, because all the same resources are still needed—compute, storage, switching, routing—but now any number of these resources may be on-prem or in the Continue reading
