Last time out we looked at some of the trade-offs between RInKs and LInKs, and the advantages of local in-memory data structures. There’s another emerging option that we didn’t talk about there: the use of far-memory, memory attached to the network that can be remotely accessed without mediation by a local processor. For many data center applications this looks to me like it could be a compelling future choice.
Far memory brings many potential benefits over near memory: higher memory capacity through disaggregation, separate scaling between processing and far memory, better availability due to separate fault domains for far memory, and better shareability among processors.
Today I’m pleased to announce a new site we have built that brings into one location links to all the content published across Internet Society websites:
Filter the view to see posts only from a specific source
For instance, you can see all the posts published by Chapters in Africa. Or you can see all the posts published in French, or Spanish, or Chinese… or Georgian.
Note that the filters can work together. By choosing “Africa” and “French” you will see only French posts from African Chapters. There’s a “Reset” link on the right side that will clear all the filters.
All the views also have unique URLs that you can share with people, or link to from other sites, email newsletters, etc. And of course the site has a master RSS feed that you can read in a RSS reader or other tool.
Deploying applications on Red Hat OpenShift or Kubernetes has come a long way. These days, it's relatively easy to use OpenShift's GUI or something like Helm to deploy applications with minimal effort. Unfortunately, these tools don't typically address the needs of operations teams tasked with maintaining the health or scalability of the application - especially if the deployed application is something stateful like a database. This is where Operators come in.
An Operator is a method of packaging, deploying and managing a Kubernetes application. Kubernetes Operators with Ansible exists to help you encode the operational knowledge of your application in Ansible.
What can we do with Ansible in a Kubernetes Operator? Because Ansible is now part of the Operator SDK, anything Operators could do should be able to be done with Ansible. It’s now possible to write an Operator as an Ansible Playbook or Role to manage components in Kubernetes clusters. In this blog, we're going to be diving into an example Operator.

It’s high time for another summer break (I get closer and closer to burnout every year - either I’m working too hard or I’m getting older ;).
Of course we’ll do our best to reply to support (and sales ;) requests, but it might take us a bit longer than usual. I will publish an occasional worth reading or watch out blog post, but don’t expect anything deeply technical for the new two months.
We’ll be back (hopefully refreshed and with tons of new content) in early September, starting with network automation course on September 3rd and VMware NSX workshop on September 10th.
In the meantime, try to get away from work (hint: automating stuff sometimes helps ;), turn off the Internet, and enjoy a few days in your favorite spot with your loved ones!

Qumulo was born at a time of change. When the company was founded seven years ago, enterprises were still running most of their business on premises, but the cloud was out there now and software-defined was gaining steam. …
Today, we’re excited to announce our partnerships with Chronicle Security, Datadog, Elastic, Looker, Splunk, and Sumo Logic to make it easy for our customers to analyze Cloudflare logs and metrics using their analytics provider of choice. In a joint effort, we have developed pre-built dashboards that are available as a Cloudflare App in each partner’s platform. These dashboards help customers better understand events and trends from their websites and applications on our network.
Cloudflare insights in the tools you're already using
Data analytics is a frequent theme in conversations with Cloudflare customers. Our customers want to understand how Cloudflare speeds up their websites and saves them bandwidth, ranks their fastest and slowest pages, and be alerted if they are under attack. While providing insights is a core tenet of Cloudflare's offering, the data analytics market has matured and many of our customers have started using third-party providers to analyze data—including Cloudflare logs and metrics. By aggregating data from multiple applications, infrastructure, and cloud platforms in one dedicated analytics platform, customers can create a single pane of glass and benefit from better end-to-end visibility over their entire stack.

Digital transformation and cloud initiatives are changing the way IT organizations are thinking about and architecting the wide area network. It is estimated that over 70 percent of applications have already moved to the cloud. Yet, the transformational promise of the cloud is falling short as conventional networks can’t keep pace with demands of the cloud. Why? Because today’s router-centric and basic SD-WAN architectures have either hit the wall or can’t keep up with traffic pattern shifts, distributed applications and the open security perimeters inherent to the cloud. This blog will explore the limitations of today’s WAN approaches, offering a better way forward with a business-first networking model.To read this article in full, please click here
One of the biggest concerns with the Internet of Things (IoT) is making sure networks, data, and devices are secure. IoT-related security incidents have already occurred, and the worries among IT, security and networking managers that similar events will take place are justified.“In all but the most restrictive environments, you’re going to have IoT devices in your midst,” says Jason Taule, vice president of standards and CISO at security standards and assurance company HITRUST. "The question then isn’t if, but how you are going to allow such devices to connect to and interact with your networks, systems and data.”To read this article in full, please click here

We often compare ourselves to others around us. We are impressed with the skills others possess, the content others produce, the appearances others maintain, the successes others have achieved, the feats others have conquered. This constant comparison can lead to melancholic states of ambivalence, and sometimes depression due to the artificial expectations of who we […]

此类不幸事件并不罕见，我们以前曾发布相关博文。这一次，全世界都再次见证了它所带来的严重损害。而Noction “BGP 优化器”产品的涉及，则让今天的事件进一步恶化。这个产品有一个功能：可将接收到的 IP 前缀拆分为更小的组成部分（称为更具体前缀）。例如，我们自己的 IPv4 路由 104.20.0.0/20 被转换为 104.20.0.0/21 和 104.20.8.0/21。就好像通往 ”北京”的路标被两个路标取代，一个是 ”北京东”，另一个是 ”北京西”。通过将这些主要 IP 块拆分为更小的部分，网络可引导其内部的流量，但这种拆分原本不允许向全球互联网广播。正是这方面的原因导致了今天的网络中断。
为了解释后续发生的事情，我们先快速回顾一下互联网基础“地图”的工作原理。“Internet”的字面意思是网络互联，它由叫做自治系统（AS）的网络组成，每个网络都有唯一的标识符，即 AS 编号。所有这些网络都使用边界网关协议（BGP）来进行互连。BGP 将这些网络连接在一起，并构建互联网“地图”，使通信得以一个地方（例如，您的 ISP）传播到地球另一端的热门网站。
Massive route leak impacts major parts of the Internet, including Cloudflare
What happened?
Today at 10:30UTC, the Internet had a small heart attack. A small company in Northern Pennsylvania became a preferred path of many Internet routes through Verizon (AS701), a major Internet transit provider. This was the equivalent of Waze routing an entire freeway down a neighborhood street — resulting in many websites on Cloudflare, and many other providers, to be unavailable from large parts of the Internet. This should never have happened because Verizon should never have forwarded those routes to the rest of the Internet. To understand why, read on.
We have blogged about these unfortunate events in the past, as they are not uncommon. This time, the damage was seen worldwide. What exacerbated the problem today was the involvement of a “BGP Optimizer” product from Noction. This product has a feature that splits up received IP prefixes into smaller, contributing parts (called more-specifics). For example, our own IPv4 route 104.20.0.0/20 was turned into 104.20.0.0/21 and 104.20.8.0/21. It’s as if the road sign directing traffic to “Pennsylvania” was replaced by two road signs, one for “Pittsburgh, PA” and Continue reading
