Announcing the Compose Specification

Docker is pleased to announce that we have created a new open community to develop the Compose Specification. This new community will be run with open governance with input from all interested parties allowing us together to create a new standard for defining multi-container apps that can be run from the desktop to the cloud. 

Docker is working with Amazon Web Services (AWS), Microsoft and others in the open source community to extend the Compose Specification to more flexibly support cloud-native platforms like Kubernetes and Amazon Elastic Container Service (Amazon ECS) in addition to the existing Compose platforms. Opening the specification will allow innovation to flourish and deliver more choices to developers, accelerating how development teams build and ship applications.

Currently used by millions of developers and with over 650,000 Compose files on GitHub, Compose has been widely embraced by developers because it is a simple cloud and platform-agnostic way of defining multi-container based applications. Compose dramatically simplifies the code to cloud process and toolchain for developers by allowing them to define a complex stack in a single file and run it with a single command. This eliminates the need to build and start every container manually, saving development Continue reading

Changing Conditions for Neural Network Processing

Over the last few years the idea of “conditional computation” has been key to making neural network processing more efficient, even though much of the hardware ecosystem has focused on general purpose approaches that rely on matrix math operations that brute force the problem instead of selectively operate on only the required pieces. …

Changing Conditions for Neural Network Processing was written by Nicole Hemsoth at The Next Platform.

Project Crossbow: Lessons from Refactoring a Large-Scale Internal Tool

Cloudflare’s global network currently spans 200 cities in more than 90 countries. Engineers working in product, technical support and operations often need to be able to debug network issues from particular locations or individual servers.

Crossbow is the internal tool for doing just this; allowing Cloudflare’s Technical Support Engineers to perform diagnostic activities from running commands (like traceroutes, cURL requests and DNS queries) to debugging product features and performance using bespoke tools.

In September last year, an Engineering Manager at Cloudflare asked to transition Crossbow from a Product Engineering team to the Support Operations team. The tool had been a secondary focus and had been transitioned through multiple engineering teams without developing subject matter knowledge.

The Support Operations team at Cloudflare is closely aligned with Cloudflare’s Technical Support Engineers; developing diagnostic tooling and Natural Language Processing technology to drive efficiency. Based on this alignment, it was decided that Support Operations was the best team to own this tool.

Learning from Sisyphus

Whilst seeking advice on the transition process, an SRE Engineering Manager in Cloudflare suggested reading: “A Case Study in Community-Driven Software Adoption”. This book proved a truly invaluable read for anyone thinking of doing internal tool development Continue reading

When We Come Together, We Are Richer for It

These are unsettling and unprecedented times.

The speed at which coronavirus has taken hold around the world, and the dramatic changes to our lives that it has brought, would have been difficult for many of us to contemplate just a few short weeks ago.

Social (and physical) distancing measures that were merely a suggestion then have suddenly become a strange reality for millions of people, with entire countries going into complete lockdown, borders and schools closing, planes no longer flying, and normal social activity placed on hold.

The vital role the Internet is playing is clear for all to see. It allows us to work together while we are socially apart, quietly and quickly providing many of us with a way to continue our lives. It has allowed us to maintain at least some sense of the ordinary during an extraordinary time.

We are asking a lot of the Internet, but it is ready for the challenge. It is enabling companies to keep working, schoolchildren to continue learning, and families and friends to stay connected. Even virtual birthday parties and weddings have become a hit!

The Internet means that self-isolation may be a physical reality, but it need not be Continue reading

Can We Trust BGP Next Hops (Part 1)?

Aldrin sent me an interesting question as a comment to one of my EVPN blog posts:

How does the network know that a VTEP is actually alive? (1) from the point of view of the control plane and (2) from the point of view of the data plane? And how do you ensure that control and data plane liveness monitoring has the same view? BFD for BGP is a possible solution for (1) but it’s not meant for 3rd party next hops, i.e. it doesn’t address (2).

Let’s stop right there (or you’ll stop reading in the next 10 milliseconds). I will also try to rephrase the question in more generic terms, hoping Aldrin won’t mind a slight detour… we’ll get back to the original question in another blog post.

The Wrong Certificate

I'm constantly impressed by the rather complex intricacies that are associated with running your own web server these days. A recent source of these complexities has been the PKI, the security infrastructure used to maintain secure connections over the network, and I'd like to recount my experience here, in case any others encounter the same seemingly inexplicable behaviours in their secure web service configurations.

Unfortunate Natural Experiment Shows the Internet Works

For many weeks now, as the pandemic caused by the coronavirus has spread around the world, people have been isolating themselves to reduce the spread of infection. Businesses and schools have closed, and whole cities have been ordered to stay indoors. People’s livelihoods have disappeared, and of course, far too many people have been critically ill or have died. It is a calamity. Yet it would be much worse, if it were not for the Internet.

It’s enabling life go on. Businesses and schools are able to continue their core activity online. People are able to order food and medicine delivery to lower the risk of contagion. Families are video conferencing to catch up, worship, and even attend weddings. Creators are streaming music and stories from their homes. Clinicians and researchers are sharing crucial medical data worldwide. Everyday citizens, remarkably informed, are trying to flatten the curve.

This is what the Internet is for: a force for good in society.

Resilient by Design

The Internet is working well under this sudden demand because of how it is designed. Nearly magic, the Internet is designed to be a reliable system built of unreliable parts. This might sound awful, as though it Continue reading

How to Easily Secure Virtual Desktops for your Remote Employees

The COVID-19 pandemic has forced many organizations to shift their business online and their employees to work from home. As a result,  business had to quickly adjust and scale up their infrastructure, sometimes with security as an afterthought.

Malicious actors are already taking advantage of this new reality by targeting the vulnerabilities commonly associated with employees connecting to corporate resources from their home environment. This includes social engineering and phishing campaigns, denial of service attacks, and exploiting vulnerabilities in home routers.

Secure VDI Environments with NSX

Providing employees working from home with secure and reliable access to their corporate resources and applications by the use of Virtual Desktop Infrastructure (VDI) helps our customers to reduce the impact on productivity and continuity as well as the risk associated with remote access to internal data.

In this blog post, I will cover a couple of use cases on how NSX can provide security for End User Compute and share some resources to help customers who are scaling up their VDI / remote desktop session host (RDSH) infrastructure to adapt to this new world in which vast numbers of employees are now working from home.

Protect Your Desktop Pools
