Cloudworker  –  A local Cloudflare Worker Runner

This is a guest post by Hank Jacobs, who is the Lead Software Engineer for Platform Services & Tools at Dollar Shave Club. This post originally appeared on the DSC Engineering blog.

Cloudworker  -  A local Cloudflare Worker Runner

At Dollar Shave Club, we continuously look for ways to improve how we build and ship code. Improving the time it takes for engineers to ship code is key. Providing engineers with a development environment that closely mirrors production really helps.

Earlier this year, we began evaluating Cloudflare Workers as a replacement for our legacy edge routing and caching layers. Cloudflare Workers brings the power of Javascript to Cloudflare’s Edge. Developers can write and deploy Javacript that gets executed for every HTTP request that passes through Cloudflare. This capability excited us but a critical thing was missing — a way to run Worker code locally. We couldn’t find a suitable solution, so we started to build our own. Luckily, Workers uses the open Service Workers API so we had documentation to consult. Within a few weeks, Cloudworker was born.

Cloudworker is a local Cloudflare Worker runtime. With it, you can run Cloudflare Worker scripts locally (or anywhere you can run a Docker image). Our primary goal with Continue reading

Does IoT come with that burger?

When I think of restaurant technology, I think of stoves and dishwashers and maybe fancy molecular gastronomy gadgets like the stuff that former Microsoft CTO Nathan Myrhvold likes to talk about.Apparently, however, even this kind of “Modernist Cuisine” is now old school when it comes to restaurant tech. The new, new thing is combining the Internet of Things (IoT) with artificial intelligence (AI) to revolutionize the front-of-the-house systems in order to predict demand, track inventory, and improve order and billing accuracy. Overall, IoT promises to help restaurants leverage IoT and AI to streamline operations, boost employee happiness, and innovate in areas beyond creating delicious new dishes.To read this article in full, please click here

Oracle introduces hybrid cloud solution – for its own cloud

I’m beginning to understand why Thomas Kurian left Oracle to try and right the foundering ship that is Google Cloud Platform. He reportedly butted heads with the boss (that would be Larry Ellison) over a desire to make Oracle products more readily available on competitive cloud platforms, and this announcement reflects that. It’s a nice bit of news if you are an Oracle customer, but not if you use a competitive product.Last week at KubeCon, the company announced the Oracle Cloud Native Framework, which is designed for organizations looking to build hybrid cloud architectures across both public cloud and on-premises infrastructure.It’s something all of the competition is doing, of course. Oracle’s efforts are best compared to Microsoft and IBM, since they also had legacy systems and customers to move to the cloud as well.To read this article in full, please click here

How to pick an off-site data-backup method

Everyone agrees that backups should be sent off site, but not everyone agrees on how that should be accomplished. The decision about which method to use will affect your recovery-time objective (RTO), recovery-point objective (RPO), risk level, and cost – so it’s rather important.To read this article in full, please click here(Insider Story)

The Importance of Container Visibility

Containers are unlike any other compute infrastructure. Prior to containers, compute infrastructure was composed of a set of brittle technologies that often took weeks to deploy. Containers made the automation of workload deployment mainstream, and brought workload deployment down to minutes, if not seconds.

Now, to be perfectly clear, containers themselves aren’t some sort of magical automation sauce that changed everything. Containers are something of a totem for IT operations automation, for a few different reasons.

Unlike the Virtual Machines (VMs) that preceded them, containers don’t require a full operating system for every workload. A single operating system can host hundreds or even thousands of containers, moving the necessary per-workload RAM requirement from several gigabytes to a few dozen megabytes. Similarly, containerized workloads share certain basic functions – libraries, for instance – from the host operating system, which can make maintaining key aspects of the container operating environment easier. When you update the underlying host, you update all the containers running on it.

Unlike VMs, however, containers are feature poor. For example, they have no resiliency: traditional vMotion-like workload migration doesn’t exist, and we’re only just now – several years after containers went mainstream – starting to get decent persistent Continue reading

On the ‘net: ATM

Asynchronous Transfer Mode, or ATM, was widely seen as a compromise technology that would provide the best circuit and packet switching in a single technology. Data would be input into the network in the form of either packets or circuits. The data would then be broken up into fixed sized cells, which would then be switched based on a fixed label-based header. This would allow hardware to switch the cells in a way that is like circuit switching, while retaining many of the advantages of a circuit switched network. In fact, ATM allowed for both circuit- and packet-switched paths to be both be used in the same network. @ECI’s LighTALK
