History Of The Internet From An Asian Perspective – Kilnam Chon

Kilnam Chon is credited as being largely responsible for bringing the Internet to Asia. In this episode we talk with Professor Chon about his experiences in the early days of the Internet and about his role in bringing the second country in the world, South Korea, onto the global network.

The Traffic Jam Whopper project may be the coolest/dumbest IoT idea ever

People love to eat in their cars. That’s why we invented the drive-in and the drive-thru.But despite a fast-food outlet on the corner of every major intersection, it turns out we were only scratching the surface of this idea. Burger King is taking this concept to the next logical step with its new IoT-powered Traffic Jam Whopper project.I have to admit, when I first heard about this, I thought it was a joke, but apparently the Traffic Jam Whopper project is totally real and has already passed a month-long test in Mexico City. While the company hasn’t specified a timeline, it plans to roll out the Traffic Jam Whopper project in Los Angeles (where else?) and other traffic-plagued megacities such as São Paulo and Shanghai.To read this article in full, please click here

Improving Routing Security: Microsoft Joins MANRS

In November, a routing incident in Nigeria caused Internet traffic to be rerouted through Russia and China. It lasted for just over an hour, but during that time, it significantly affected some cloud and search services globally, including Spotify and Google’s Search. It was one of more than 10,000 incidents, such as route hijacking and leaks, that occurred in 2018. Past events have led to large-scale Denial of Service attacks, stolen data, and financial losses.

The global routing system is the backbone of the Internet. It determines how everything – from email messages to videoconferences to website content – moves from network to network. The November event, caused by a configuration mistake with a small ISP in Nigeria, shows that routing incidents can have significant global effects – impacting the security of the Internet itself.

A number of network operators around the world – including Oracle, GÉANT, and Comcast – have joined MANRS to address these types of routing threats. The Mutually Agreed Norms for Routing Security (MANRS) initiative, supported by the Internet Society, does this through technical and collaborative action across the Internet. Those who join agree to take meaningful action to keep the Internet safe for everyone – Continue reading

Don’t Base Your Design on Vendor Marketing

Remember how Arista promoted VXLAN coupled with deep buffer switches as the perfect DCI solution a few years ago? Someone took Arista’s marketing too literally, ran with the idea and combined VXLAN-based DCI with traditional MLAG+STP data center fabric.

While I love that they wrote a blog post documenting their experience (if only more people would do that), it doesn’t change the fact that the design contains the worst of both worlds.

Here are just a few things that went wrong:

Software-defined far memory in warehouse scale computers

Software-defined far memory in warehouse-scale computers Lagar-Cavilla et al., ASPLOS’19

Memory (DRAM) remains comparatively expensive, while in-memory computing demands are growing rapidly. This makes memory a critical factor in the total cost of ownership (TCO) of large compute clusters, or as Google like to call them “Warehouse-scale computers (WSCs).”

This paper describes a “far memory” system that has been in production deployment at Google since 2016. Far memory sits in-between DRAM and flash and colder in-memory data can be migrated to it:

Our software-defined far memory is significantly cheaper (67% or higher memory cost reduction) at relatively good access speeds (6µs) and allows us to store a significant fraction of infrequently accessed data (on average, 20%), translating to significant TCO savings at warehouse scale.

With a far memory tier in place operators can choose between packing more jobs onto each machine, or reducing the DRAM capacity, both of which lead to TCO reductions. Google were able to bring about a 4-5% reduction in memory TCO (worth millions of dollars!) while having negligible impact on applications.

In introducing far memory Google faced a number of challenges: workloads are very diverse and change all the time, both in job Continue reading

BrandPost: Mobility and SD-WAN, Part 2: Is SD-WAN the Super-Glue That Will Bring 5G and all the Edges Together?

This is the second blog of a two-part blog series that explores SD-WAN and the future of networking in the 5G era. Part 1 “SD-WAN with 4G LTE is a Reality” can be found here.5G, a game-changer for an ultra-high-speed, hyperconnected world Telecommunications providers are racing to roll out the fifth generation of mobile wireless technology to meet today’s explosive bandwidth and network connectivity demands. 5G is poised to revolutionize several industries by bringing significantly faster connections, shorter delays and increased connectivity for users. It will aid the expansion of “internet of things” (IoT), creating a virtual network of ultra-high-speed connections across multiple devices. To read this article in full, please click here

Enterprise IoT: Companies want solutions in these 4 areas

Internet of things (IoT) vendors and pundits like to crow about the billions and billions of connected devices that make the IoT so ubiquitous and powerful. But how much of that installed base is really relevant to the enterprise?To find out, I traded emails with Rob Mesirow, principal at PwC’s Connected Solutions, the firm’s new one-stop-shop of IoT solutions, who suggests that consumer adoption may not paint a true picture of the enterprise opportunities. If you remove the health trackers and the smart thermostats from the market, he suggested, there are very few connected devices left.To read this article in full, please click here

Building a To-Do List with Workers and KV

Building a To-Do List with Workers and KV
Building a To-Do List with Workers and KV

In this tutorial, we’ll build a todo list application in HTML, CSS and JavaScript, with a twist: all the data should be stored inside of the newly-launched Workers KV, and the application itself should be served directly from Cloudflare’s edge network, using Cloudflare Workers.

To start, let’s break this project down into a couple different discrete steps. In particular, it can help to focus on the constraint of working with Workers KV, as handling data is generally the most complex part of building an application:

  1. Build a todos data structure
  2. Write the todos into Workers KV
  3. Retrieve the todos from Workers KV
  4. Return an HTML page to the client, including the todos (if they exist)
  5. Allow creation of new todos in the UI
  6. Allow completion of todos in the UI
  7. Handle todo updates

This task order is pretty convenient, because it’s almost perfectly split into two parts: first, understanding the Cloudflare/API-level things we need to know about Workers and KV, and second, actually building up a user interface to work with the data.

Understanding Workers

In terms of implementation, a great deal of this project is centered around KV - although that may be the case, it’s useful to break Continue reading

Get ready to write — Workers KV is now in GA!

Get ready to write — Workers KV is now in GA!

Today, we’re excited to announce Workers KV is entering general availability and is ready for production use!

Get ready to write — Workers KV is now in GA!

What is Workers KV?

Workers KV is a highly distributed, eventually consistent, key-value store that spans Cloudflare's global edge. It allows you to store billions of key-value pairs and read them with ultra-low latency anywhere in the world. Now you can build entire applications with the performance of a CDN static cache.

Why did we build it?

Workers is a platform that lets you run JavaScript on Cloudflare's global edge of 175+ data centers. With only a few lines of code, you can route HTTP requests, modify responses, or even create new responses without an origin server.

// A Worker that handles a single redirect,
// such a humble beginning...
addEventListener("fetch", event => {
  event.respondWith(handleOneRedirect(event.request))
})

async function handleOneRedirect(request) {
  let url = new URL(request.url)
  let device = request.headers.get("CF-Device-Type")
  // If the device is mobile, add a prefix to the hostname.
  // (eg. example.com becomes mobile.example.com)
  if (device === "mobile") {
    url.hostname = "mobile." + url.hostname
    return Response.redirect(url, 302)
  }
  // Otherwise, send request to the original hostname.
  return await fetch(request)
