China | Silicon Valley | China: A path less traveled

Don’t tell our CEO, Matthew Prince, but the first day I interviewed at Cloudflare I had a $9.00 phone in my pocket, a knock-off similar to a Nokia 5140, but the UI was all in Chinese characters—that phone was a fitting symbol for my technical prowess. At that time in my career I could send emails and use Google, but that was about the extent of my tech skill set. The only code I’d ever seen was in the Matrix, Apple computers confused me, and I was working as a philosophy lecturer at The University of California, Santa Cruz. So, you know, I was pretty much the ideal candidate for a deeply technical, Silicon Valley startup.

This was in 2013. I had just returned from two years of Peace Corps service in the far Southwest of China approaching the Himalayan plateau. That experience gave me the confidence to walk into Cloudflare’s office knowing that I would be good for the job despite the gaps in my knowledge. My early training in philosophy plus my Peace Corps service gave me a blueprint for learning and Continue reading

Shifting Responsibility in Network Design and Operations

When I started working with Cisco routers in late 1980s all you could get were devices with a dozen or so ports, and CPU-based forwarding (marketers would call it software defined these days). Not surprisingly, many presentations in Cisco conferences (before they were called Networkers or Cisco Live) focused on good network design and split of functionality in core, aggregation (or distribution) and access layer.

What you got following those rules were stable and predictable networks. Not everyone would listen; some customers tried to be cheap and implement too many things on the same box… with predictable results (today they would be quick to blame vendor’s poor software quality).

Cisco, Google reenergize multicloud/hybrid cloud joint development

Cisco and Google have expanded their joint cloud-development activities to help customers more easily build secure multicloud and hybrid applications everywhere from on-premises data centers to public clouds.[Check out what hybrid cloud computing is and learn what you need to know about multi-cloud. Get regularly scheduled insights by signing up for Network World newsletters] The expansion centers around Google’s new open-source hybrid cloud package called Anthos, which was introduced at the company’s Google Next event this week. Anthos is based on – and supplants – the company's existing Google Cloud Service beta. Anthos will let customers run applications, unmodified, on existing on-premises hardware or in the public cloud and will be available on Google Cloud Platform (GCP) with Google Kubernetes Engine (GKE), and in data centers with GKE On-Prem, the company says. Anthos will also let customers for the first time manage workloads running on third-party clouds such as AWS and Azure from the Google platform without requiring administrators and developers to learn different environments and APIs, Google said. To read this article in full, please click here

BrandPost: Enhanced security at the edge

It’s becoming a cliché to say that data security is a top concern among executives and boards of directors. The problem is: the problem just won’t go away.Hackers and attackers are ever finding new ways to exploit weaknesses. Just as companies start to use emerging technologies like artificial intelligence and machine learning to protect their organizations in an automated fashion, so too are bad actors using these tools to further their goals.In a nutshell, security simply cannot be overlooked. And now, as companies increasingly adopt edge computing, there are new considerations to securing these environments.To read this article in full, please click here

VMware and Google Showcase Hybrid Cloud Deployment for Application Platform and Development Teams

VMware and Google have been collaborating on a hybrid cloud for application platform and development teams. Both Google and VMware’s platforms are built on community-driven open-source technologies – namely Kubernetes, Envoy, and Istio. Having a common hybrid cloud foundation allows teams to run their applications on the optimal infrastructure and gives them more choice when modernizing existing applications or developing new cloud-native applications.

Digital transformation is rapidly changing the IT and application landscape. We are seeing a confluence of transformations that are happening simultaneously. These include hybrid clouds, microservice architectures, containerized applications, and service meshes – to name a few.

In this blog post, I will walk you through the architecture and specific use cases to illustrate the value a hybrid cloud deployment can deliver to application platform and development teams. We’ll do this by showing how a retail company can leverage many of these technology trends to help transform its business.

Internet Society and UNESCO Offer a Capacity Building Program for Judges

Trust is vital to the future of the Internet. The best way to build it is to let a diverse group of people and interested organizations contribute their experience and knowledge. For this reason, the Internet Society and the UNESCO Regional Office has developed a capacity-building program for judges, prosecutors, public defenders, and other judicial operators in Latin America and the Caribbean.

This program shares our vision for an open, globally-connected, trustworthy, and secure Internet for everyone. We allied with UNESCO to incorporate a plan related to freedom of expression, privacy, encryption, and access to public information. In this way the program responds to the needs of judicial operators facing real cases related to the use of the Internet.

For Raquel Gatto, Senior Policy Advisor of the Internet Society, the program represents an unprecedented opportunity: “The technical foundations of the Internet show us that collaboration is a fundamental factor for the functioning of the network. The Internet is a network of networks that trust each other, allowing interconnection. The Internet can not exist without such collaboration”.

Guilherme Canela, Regional Councilor for Communication and Information of UNESCO, says, “For 5 years, UNESCO, in cooperation with the Special Rapporteur for Freedom of Continue reading

The real challenge to achieving 5G: the networks

Everyone seems focused on whether major device makers can ship 5G-ready phones. And indeed they are coming forward with devices (e.g., Samsung, Huawei) based on chip designs from major manufacturers (e.g., Qualcomm, Huawei, Intel).But while many are focused on the device challenges (such as will Apple’s iPhones use Qualcomm or Intel modems, or design their own?) and the potentially billions of connected “things” expected in the next few years, the devices are just the tip of the iceberg when it comes to 5G. The real “below the water line” challenges, the more than 80% of the challenges in making 5G real, are in updating and creating networks that can truly provide all of the variety of services and capabilities that we expect.To read this article in full, please click here

Working with variables on Linux

A lot of important values are stored on Linux systems in what we call “variables,” but there are actually several types of variables and some interesting commands that can help you work with them. In a previous post, we looked at environment variables and where they are defined. In this post, we're going to look at variables that are used on the command line and within scripts.User variables While it's quite easy to set up a variable on the command line, there are a few interesting tricks. To set up a variable, all you need to do is something like this:To read this article in full, please click here

BrandPost: AI Ops: Let the data talk

Marie Fiala, Director of Portfolio Marketing for Blue Planet at Ciena The catalysts and ROI of AI-powered network analytics for automated operations were the focus of discussion for service providers at the recent FutureNet conference in London. Blue Planet’s Marie Fiala details the conversation.Do we need perfect data? Or is ‘good enough’ data good enough? Certainly, there is a need to find a pragmatic approach or else one could get stalled in analysis-paralysis. Is closed-loop automation the end goal? Or is human-guided open loop automation desired? If the quality of data defines the quality of the process, then for closed-loop automation of critical business processes, one needs near-perfect data. Is that achievable?To read this article in full, please click here

The Microsoft/BMW IoT Open Manufacturing Platform might not be so open

Last week at Hannover Messe, Microsoft and German carmaker BMW announced a partnership to build a hardware and software technology framework and reference architecture for the industrial internet of things (IoT), and foster a community to spread these smart-factory solutions across the automotive and manufacturing industries.The stated goal of the Open Manufacturing Platform (OMP)? According to the press release, it's “to drive open industrial IoT development and help grow a community to build future Industry 4.0 solutions.” To make that a reality, the companies said that by the end of 2019, they plan to attract four to six partners — including manufacturers and suppliers from both inside and outside the automotive industry — and to have rolled out at least 15 use cases operating in actual production environments.To read this article in full, please click here
