What to expect from SD-WANs in 2019

In network circles, there may be no hotter topic right now than software-defined WAN (SD-WAN). Given WAN technology stood still for the better part of three decades, this makes sense, as most companies have a WAN that’s long overdue for a refresh and architectural update — and SD-WANs make this a reality.SD-WANs are definitely moving out of the early-adopter phase and into mainstream adoption. And anytime a technology does this, the market changes. Below are the primary ways SD-WANs will change in 2019.[ Check out: 10 hot SD-WAN startups to watch | Get regularly scheduled insights: Sign up for Network World newsletters ] Less focus on cost savings The initial wave of SD-WANs was sold with the promise of slashing network costs by replacing MPLS with broadband. If a business is willing to ditch all of its MPLS, and that’s a big if, and replace it wholly with broadband, it will save money on transport. However, it will likely need to add some optimization technologies to account for the unpredictability of broadband.To read this article in full, please click here

Stuff The Internet Says On Scalability For December 14th, 2018

Wake up! It's HighScalability time:

We've come a long way in 50 years. Or have we?

Alan Kay: I believe ARPA spent $ 175,000 of 1968 money for that one demo. That’s probably like a million bucks today.

Bill English: What we did was lease two video circuits from the phone company. They set up a microwave link: two transmitters on the top of the building at SRI, receiver/ transmitters up on Skyline Boulevard on a truck, and two receivers at the Civic Center. Cables of course going down into the room at both ends. That was our video link. Going back we had two dedicated 1,200-baud lines: high-speed lines at the time. Homemade modems.

Doug Engelbart: It was the very first time the world had ever seen a mouse, seen outline processing, seen hypertext, seen mixed text and graphics, seen real-time videoconferencing.

Alan Kay: We could actually see that ideas could be organized in a different way, that they could be filtered in a different way, that what we were looking at was not something that was trying to automate current modes of thought, but that there should be an amplification relationship between us and this new technology.

Bridging the Gender Gap in Serbia

We are delighted that our project, Digitally Unconnected Gender Gap (DUGG) has been chosen by the Internet Society as part of the Beyond the Net Funding Programme to work on digital gender issues in Serbia.

The gender digital gap is widely present in Serbia, but the lack of research data and statistics are making this problem invisible, both from the ones dealing with women’s rights, and the ones who are fighting for a just, accessible, and safe Internet for everyone. Our team will connect these two activists’ fields in order to put the light on the issue!

Through these project activities, the team from Serbia Chapter will be dedicated to explore how ICT technologies and Internet can play a role in decreasing the existing gender digital gap and how to take into consideration gender awareness in developing new and evolving technologies.

As women comprise half of the world’s population, the UN’s Sustainable Development Goals (SDG) should address each of the goals through a gendered lens. The DUGG plans to focus on the Sustainable Development Goals 4 (Quality Education), 5 (Gender Equality), and 9 (Industry Innovation and Infrastructures). However, if applications and services are developed by women, they would be more relevant Continue reading

Short Take – Nerd Knobs

Complexity is a reality for most modern networks but unnecessary complexity can do more harm than good. In this Network Collective Short Take, Russ and Eyvonne talk through the consequences of enabling new features and share their insight on when you should, and when you shouldn’t, reach for the infamous nerd knobs.

Managing DNS Records For The People With Cloudflare Apps

Managing DNS Records For The People With Cloudflare Apps

DNS records are hard.  Many people, even the technically competent, don’t understand more than the basics.

Managing DNS Records For The People With Cloudflare Apps

I'll speak for myself — as someone who always learned just enough about DNS to get it working, then immediately forgot everything until the next time it broke. It was a vicious cycle until I convinced myself to learn it in depth.  Meanwhile, non-technical folks wisely avoid meddling in such dangerous affairs all together.

Surely, there must be a better way (this is a blog post after all).

Every day, thousands of Cloudflare users add DNS records to their Internet properties to configure awesome tools like G Suite, Shopify, Wordpress, Ghost, and thousands of others.  A new Cloudflare Apps feature allows apps to automatically set up and manage configurable DNS records on more than 12 million registered domains on the Cloudflare network. In short, Cloudflare Apps are here to alleviate the Internet’s collective DNS woes.

Gone are the days of tribulating over whether it’s A or CNAME you should set.  Gone are the days of puzzling between A and AAAA records while wondering what the heck happened to AA and AAA records?  Unload your DNS dysphoria onto highly trained developers experienced at explicating these Continue reading

Has Anyone Actually Sued Their Vendor ?

An oft-quoted reason for buying technology from a commercial vendor is legal recourse. If it fails, the company imagines that it could sue the supplier for negligence or reparations.  Vendors offer zero guarantees that their products work. If you read the purchase contracts, the customer waives all rights when using the products including the right […]

Kubernetes vendors target container security, operations and management

If you were kicking the tires on Kubernetes and other cloud/container services, you found may have found nirvana at this week’s KubeCon + CloudNativeCon 2018 where all manner of new operational software and support from VMware, Arista and others were on display.To access the growing popularity of cloud, Kubernetes and containers, the Cloud Foundry Foundation released the results of a new survey that found among other things that 45 percent of companies are doing at least some cloud-native app development, and 40 percent are doing some re-architecting/refactoring of their legacy apps.To read this article in full, please click here

Darwinian data structure selection

Darwinian data structure selection Basios et al., FSE’18

GraphIt may have caught your attention for the success of its approach, but I suspect for many readers it’s not something you’ll be immediately applying. Darwinian Data Structures (DDSs) on the other hand looks to be of immediate interest to many Java and C++ projects (and generalises beyond those languages).

What I would have called an ADT (e.g., a List), the authors call Darwinian Data Structures. The ‘Darwinian’ part comes from the fact that ADTs have multiple concrete implementations, and Artemis, “a multi-objective, cloud-based search-based optimisation framework” finds the best implementation class (e.g. ArrayList, LinkedList) for your specific use case. It does this using the NSGA-II genetic algorithm-based optimiser in the current implementation.

In brief, Artemis finds the places in your code where you are using an ADT, and explores the possible concrete instantiation space for those ADTs using your test suite as a guide to performance. Then it outputs the transformed source. You might be wondering whether e.g. LinkedList vs ArrayList makes that big a difference in most real world projects:

Artemis achieves substantial performance improvements for every project in Continue reading
