Message from Internet Society Audit Committee Chair

As Chair of the Internet Society Audit Committee, I wanted to share an update with you.

As you may know, the Audit Committee reviews the Conflict of Interest forms filed by members of the Board of Trustees and officers of the Internet Society to ensure that we are in compliance with our Conflict of Interest (“CoI”) policy.

The CoI policy states that members of the Board of Trustees cannot hold a position in the policy development process in another organization operating in the Internet Society’s areas of engagement, and we are evaluating a situation where this restriction may be relevant. One of our Trustees has been appointed as a non-voting member to the GSNO Council, the Generic Names Supporting Organization – a policy-development body that develops and recommends policies relating to generic top-level domains (gTLDs) to the ICANN Board.

The Internet Society has a long history of collaborating with our diverse community from around the world, and is committed to having vibrant and robust global engagement. We work across countries and cultures and seek diverse cross-organizational expertise. This makes us stronger—sound practices and clear policies are a critical part of that.

We recognize that the expertise of our trustees is Continue reading

Automating Helm using Ansible

Increasing business demands are driving the need for increased automation to support rapid, yet stable, and reliable deployments of applications and supporting infrastructure. Kubernetes and cloud-native technologies are no different. For the Kubernetes platform, Helm is the standard means of packaging, configuring and deploying applications and services onto any cluster.

We recently released the kubernetes.core 1.1, our first Red Hat Certified Content Collection release, for general use. A big part of the new content that has been introduced is support for automating Helm operations. In this blog post, I will show you some common scenarios for its use in your automation.

Please note that prior to the release of kubernetes.core 1.1, its contents were released as community.kubernetes. With this content becoming Red Hat support and certified content, a name change was in order. We are in the process of making that transition. 

 

A Quick Introduction to Helm

Helm is an open source tool used for packaging and deploying applications on Kubernetes. It is often called Kubernetes Package Manager. It is widely adopted by the Kubernetes community and the Cloud Native Computing Foundation (CNCF) graduate project.

Helm simplifies deployment of the applications by abstracting Continue reading

Do We Need LFA or FRR for Fast Failover in ECMP Designs?

One of my readers sent me a question along these lines:

Imagine you have a router with four equal-cost paths to prefix X, two toward upstream-1 and two toward upstream-2. Now let’s suppose that one of those links goes down and you want to have link protection. Do I really need Loop-Free Alternate (LFA) or MPLS Fast Reroute (FRR) to get fast (= immediate) failover or could I rely on multiple equal-cost paths to get the job done? I’m getting different answers from different vendors…

Please note that we’re talking about a very specific question of whether in scenarios with equal-cost layer-3 paths the hardware forwarding data structures get adjusted automatically on link failure (without CPU reprogramming them), and whether LFA needs to be configured to make the adjustment happen.

Updates on Hub Rate Limits, Partners and Customer Exemptions

The gradual enforcement of the Docker Hub progressive rate limiting enforcement on container image pulls for anonymous and free users began Monday, November 2nd. The next three hour enforcement window on Wednesday, November 4th from 9am to 12 noon Pacific time. During this window, the eventual final limit of 100 container pull requests per six hours for unauthenticated users and 200 for free users with Docker IDs will be enforced. After that window, the limit will rise to 2,500 container pull requests per six hours. 

As we implement this policy, we are looking at the core technologies, platforms and tools used in app pipelines to ensure a transition that supports developers across their entire development lifecycle. We have been working with leading cloud platforms, CI/CD providers and other ISVs to ensure their customers and end users who use Docker have uninterrupted access to Docker Hub images. Among these partners are the major cloud hosting providers, CI/CD vendors such as CircleCI, and OSS entities such as Apache Software Foundation (ASF). You can find more information about programs on our Pricing Page as well as links to contact us for information about programs for ISVs and companies with more than 500 Continue reading

Anatomy of a Binary Executable

Even though I’ve developed software for a number of years now, there’s one question that has always been in the back of my mind and I haven’t had the time or patience to really answer, until now: What is a binary executable anyways? For this example, I wrote a brutally simple Rust program that includes a function “sum” to add two integers together, and am invoking it from main(): fn main() { println!

What are data centers, and how are they changing?

A data center is a physical facility that enterprises use to house their business-critical applications and information. As they evolve, it’s important to think long-term about how to maintain their reliability and security.What is a data center? Data centers are often referred to as a singular thing, but in actuality they are composed of a number of technical elements. These can be broken down into three categories: Compute: The memory and processing power to run the applications, generally provided by high-end servers Storage: Important enterprise data is generally housed in a data center, on media ranging from tape to solid-state drives, with multiple backups Networking: Interconnections between data center components and to the outside world, including routers, switches, application-delivery controllers, and more These are the components that IT needs to store and manage the most critical systems that are vital to the continuous operations of a company. Because of this, the reliability, efficiency, security and constant evolution of data centers are typically a top priority. Both software and hardware security measures are a must.To read this article in full, please click here

Home Network 2020

Recently I moved to a new house and as a lot of reconstruction was done to bring the house up to date. I took the opportunity to have something I’ve always wanted in my home: a server rack! In my previous lab set-ups they were either located in my employers lab location or placed in […]

Heavy Networking 548: Automating Multi-DC EVPN With Apstra (Sponsored)

If you’ve been looking at automation for your network, you should listen to this episode. This is one of those discussions that can help you understand whether you should roll your own artisanal automation, lovingly handcrafted with Python scripts flowing from your keyboard, or whether your organization would be better served with a commercially supported tool like Apstra. That’s the choice Beelastic needed to make, and we’re going to discuss why they went the Apstra direction. Apstra customer Beelastic is going to tell their tale of data center fabric, multiple data centers, automation, validation, multi-tenancy, EVPN, and more.

Remotely Triggered Black Hole Filtering

Remotely triggered black hole (RTBH) filtering is a technique that provides the ability to drop undesirable traffic before it enters a protected network. It is used for the mitigation of distributed-denial-of-service (DDoS) and DoS attacks. We will show configuration of destination and source RTBH for Cisco IOS-XR in a network depicted on the Picture 1. […]
