Happy Amazon Crash Day

On one of the biggest shopping days of the year for Amazon.com the company’s web site crapped out intermittently for hours yesterday.Instead of Prime Day purchases, many customers just got error messages and pictures of the dogs of Amazon, along with a message from Amazon that read: "Sorry, we're experiencing unusually heavy traffic. Please try again in a few seconds. Your items are still waiting in your cart," or “"Uh-Oh. Something went wrong on our end." [ Related: How to plan a software-defined data-center network.] Prime Day started at 3PM ET and the problems emerged almost immediately after.  Around 5 p.m., Amazon tweeted acknowledgement of the problem stating: “Some customers are having difficulty shopping and we are working to resolve this issue quickly.  Many are shopping successfully – in the first hour of Prime day in the US, customers have ordered more items compared to the first hour last year.”To read this article in full, please click here

BrandPost: How Cloud Migration Impacts Network Infrastructure

The Cloud ImperativeEnterprise IT is increasingly a multi-cloud affair. With Gartner projecting that 85 percent of enterprises are currently using a multi-cloud strategy, it seems difficult to find an enterprise that doesn’t. IT leaders are like conductors – orchestrating SaaS, PaaS, and on-premises code and data in increasingly virtualized, software-defined environment. With the cloud taking center stage, what impacts does migration of workloads have on infrastructure overall?Migration Challenges for InfrastructureAs IT strives to be more responsive to both lines of business and development teams seeking to spin up new instances and environments, workloads often need to move – and rapidly. But workload mobility has a downside, namely an increasing demand on the shared services on- and off-premises.To read this article in full, please click here

Worth Reading: Source Address Dependent Routing

Having multiple connections to the Internet, or being multihomed, is often a must to avoid a single point of failure. But, it is not as simple as getting two connections to the Internet — most Internet Service Providers (ISP) apply anti-spoofing so all packets sent on one ISP uplink must use a source address from this ISP. —Eric Vyncke @APNIC

The Pursuit of Inspired Leadership

At Arista Networks, great technology and leadership inspires us to innovate and continue our mission to reinvent. It’s an ongoing journey to create the right leaders and disruptive technology for market transitions and Arista’s evolution. Today I digress a bit, as I was reading a 2017 Harvard Business Review article on the four key traits identified for successful CEOs. So much of it resonated with me with respect to the Arista way and our company culture. Let’s review how these traits apply to a fast-paced technology company like Arista.

Dynamic Kubernetes Client for Ansible

tl;dr

We condensed the Python Kubernetes/OpenShift client from 400,000 lines of code to 500, while adding features and closing nearly all known bugs. The new Kubernetes modules shipping in Ansible 2.6 support all resources the Kubernetes server supports, and fix nearly all the bugs that were in the 2.5 k8s_raw and openshift_raw modules. If you want to control your Kubernetes infrastructure with Ansible, now is a very good time to give it a try.

Previous Approaches

For anyone who has not followed the process of adding Kubernetes support to Ansible, this is actually our third attempt. With this iteration, we have finally worked out a lot of the kinks that made the modules difficult to use. Here’s a brief synopsis of the history of the project:

Generated client, generated modules

Our first iteration was backed by a generated OpenShift Python client, based on the existing Kubernetes Python client. This Python client ingested the OpenAPI spec for the OpenShift/Kubernetes API and generated one or more modules per resource type. Due to the size of the API, this resulted in ~400,000 lines of generated code.

The Ansible Kubernetes modules were in turn generated from the generated client, so for Continue reading

Innovative Approaches to Connecting Indigenous Communities

In November 2017, the Internet Society hosted its first Indigenous Connectivity Summit in Santa Fe, New Mexico. This event brought together over 200 Indigenous community members to talk about Internet access solutions, and the importance of connectivity for socioeconomic, health, community empowerment, education, and cultural and language preservation.

It was an incredible two days that resulted in new, meaningful relationships, partnerships, and opportunities for all those present. But the work isn’t done yet.

Connectivity in Indigenous communities continues to lag far behind non-Indigenous areas. Low speeds or non-existent service, high costs, and data caps plague many communities. In some Arctic communities in Canada, it is often cheaper and faster to mail a USB drive south, upload data, and mail it back North than it is to download the content on the slow and expensive services available.

To continue the conversation that was started in Santa Fe, the Internet Society will hold the second Indigenous Connectivity Summit in Inuvik, Northwest Territories, Canada on October 11-12. This event will bring together Indigenous community leaders, technical experts, researchers, policy makers, and service providers to address the unique connectivity issues Alaska Native, American Indian, Inuit, First Nation, and Métis communities face and how they Continue reading

Amazon rumored to be entering the networking market

It’s hard to remember a time when people thought Amazon was nuts for going into the cloud computing business, since it was so far removed from the company’s core ecommerce business. No one is laughing now.It seems history could repeat itself. According to an article in The Information, Amazon is rumored to be targeting a new industry, albeit one dominated by a giant player and multiple healthy competitors — the network switching business. The move would put it in direct competition with Cisco, HPE, Juniper Networks, and Arista.To read this article in full, please click here

The Uncertainty of Measuring the DNS

In this article I’d like to explore a common aspect of measurements of the Internet’s Domain Name system. It’s nowhere near as formally stated as Heisenberg’s Uncertainty Principle, and cannot be proved formally, but the assertion is very similar, namely that there is a basic limit to the accuracy of measurements that can be made about the behaviour and properties of the DNS.

Making Application Collaboration Easier with Docker Application Packages

In the first blog post about the experimental Docker Application Packages, Gareth showed how our new open-source docker-app can be used to augment Compose files by adding metadata and separate settings.

Now that you know how to create an Application Package, how do you share it? Using a Docker registry solution like Docker Hub or Docker Enterprise of course! Let’s look at an example that works with the latest release of docker-app. Here’s a simple single-file format Application Package with the filename hello.dockerapp:

# This section contains your application metadata.

version: 0.1.0
name: hello
description: "A simple HTTP echo server"
maintainers:
- name: Chris Crone
  email: [email protected]
targets:
  swarm: true
  kubernetes: true

---

# This section contains the Compose file that describes your application services.

version: '3.6'
services:
  hello:
    image: hashicorp/http-echo:${version}
    command: ["-text", "${text}"]
    ports:
      - ${port}:5678

 ---

# This section contains the default values for your application settings.

port: 5678
text: hello development
version: latest

We can save this Application Package as a Docker image using the save command:

$ docker-app save
Saved application as image: hello.dockerapp:0. Continue reading
