Its pièce de résistance is to use software-defined networking to take resources from clouds and on-premises data centers and make it look like it’s a single data center, all on the same Layer 2.
Consul competes against Istio but has a broader focus on multi-tenancy infrastructure deployments.
Telefónica taps Netcracker for BSS; Cisco launches hybrid cloud platform for Google Cloud; China considers a merger of its three wireless carriers.
The company says its four 5G launch markets will be used to refine its customer experience and stress-test the network.
Hey, it's HighScalability time:
Get antsy waiting 60 seconds for a shot? Imagine taking over 300,000 photos over 14 years, waiting for Mount Colima to erupt. Sergio Tapiro studied, waited, and snapped.
Do you like this sort of Stuff? Please lend me your support on Patreon. It would mean a great deal to me. And if you know anyone looking for a simple book that uses lots of pictures and lots of examples to explain the cloud, then please recommend my new book: Explain the Cloud Like I'm 10. They'll love you even more.
Did the passage of gDPR impact the amount of spam on the ‘net, or not? It depends on who you ask.
The folks at the Recorded Future blog examined the volume of spam and the number of registrations for domains used in phishing activity, and determined the volume of spam was not impacted by the implementation of Europe’s new privacy laws.
To understand the effect of GDPR, the relevant questions are: Is GDPR enabling damage, because it makes detection, blocking, and mitigation harder?
Note that the CircleID article only addresses the domain registration question, and does Continue reading
DevOpsDays is a technical conference for developers, system administrators and anyone else, whether expert or beginner, involved in technology. With technology and responsibilities crossing over spaces, DevOps is a movement that has rapidly spread through the technical community along with the adoption of agile techniques. DevOps Days take place all over the world as self-organized events which community members who are passionate about their work attend. The format of presentations, Ignites and Open Spaces is unique to this event. It is highly interactive and invigorating for attendees.
We’d love to get feedback from you, our customers, on what courses you’d like to see next. We’re constantly working to create new content which caters to a variety of technical certifications. We need your help deciding the best topics to add to our ever-exanding DevOps course library. As a token of appreciation, everyone who visits our booth and assists us by suggesting DevOps course topics will be entered into a contest to win a Nintendo Switch.
Interested in working with us? We’re looking for Continue reading
In this Network Collective Short Take, Russ White reviews a research paper on PFAT Trees and how they might be used in multichannel datacenter topologies.
The post Short Take – PFAT Trees appeared first on Network Collective.
When someone tells me they have bought smart light bulbs, an Internet-connected pet cam, or any other Internet of Things (IoT) device, I always get an unsettled feeling in the pit of my stomach. They’re so excited about the affordances or their new IoT devices and apps, but I am skeptical about the privacy and security vulnerabilities. How do I have a conversation about these concerns without coming across as hyper paranoid? Perhaps the answer is that we aren’t quite ready to discuss these issues on a societal level.
Privacy and security advocates all over the world have been talking about the threats that IoT may pose to society – unless standards and regulations are put in place to help mitigate some of these risks. They champion that privacy and security should be built into design and should not come as an afterthought.
While I praise the work that advocates are doing, IoT devices are on the shelves right now and we need to be able to have conversations with everyday folk about what privacy and security risks look like in the digital economy. However, how can we have these conversations when we haven’t yet established understandable and common terms Continue reading
About six months ago, I got fed up with my Meraki MR34 APs. They ran just fine, but they needed attention. They needed licenses. They needed me to pay for a dashboard I used rarely but yet had to keep up yearly. And that dashboard had most of the “advanced” features hidden away under lock and key. I was beyond frustrated. I happen to be at the Wireless LAN Professionals Conference (WLPC) and ran into Darrell DeRosia (@Darrell_DeRosia) about my plight. His response was pretty simple:
“Dude, you should check out Ubiquiti.”
Now, my understanding of Ubiquiti up to that point was practically nothing. I knew they sold into the SMB side of the market. They weren’t “enterprise grade” like Cisco or Aruba or even Meraki. I didn’t even know the specs on their APs. After a conversation with Darrell and some of the fine folks at Ubiquiti, I replaced my MR34s with a UniFI AP-AC-HD and an AP-AC-InWall-Pro. I also installed one of their UniFi Security Gateways to upgrade my existing Linksys connection device.
You may recall my issue with redundancy and my cable modem battery when I tried to install the UniFi Security Gateway for Continue reading
Welcome to Technology Short Take 104! For many of my readers, VMworld 2018 in Las Vegas was “front and center” for them since the last Tech Short Take. Since I wasn’t attending the conference, I won’t try to aggregate information from the event; instead, I’ll focus on including some nuggets you may have missed amidst all the noise.
Nothing this time around, but I’ll stay alert for items to include next time!
When troubleshooting application performance issues, ping alone may not detect the problem. That’s where active testing can help.
Johannes Weber was forced to stress-test the IPv6 networks are easy to renumber nonsense and documented his test results – a must-read for everyone deploying IPv6.
He found out that renumbering IPv6 in his lab required almost four times as many changes as renumbering (outside) IPv4 in the same lab.
My cynical take on that experience: “Now that you’ve documented everything that needs to be changed, make sure it’s automated the next time ;)”
Unveiling and quantifying Facebook exploitation of sensitive personal data for advertising purposes Cabañas et al., USENIX Security 2018
Earlier this week we saw how the determined can still bypass most browser and tracker-blocking extension protections to track users around the web. Today’s paper is a great example of why you should care about that. Cabañas et al. examine the extent to which the profile Facebook builds on its users includes sensitive personal data made available to advertisers for targeting. The work was done just prior to the GPDR coming into force, which makes for very interesting timing from a legal perspective. The headline result is that it looks like Facebook is holding sensitive data on about 40% of the EU population, and that this data can be used by third-parties to target individuals in sensitive demographics and even identify them at a cost of as little as €0.015 per user.
The GDPR definition of sensitive personal data is “data revealing racial or ethnic origin, political opinions, religious or philosophical beliefs, or trade union membership, and the processing of genetic data, biometric data for the purpose of uniquely identifying Continue reading

Let’s talk about lasers! In this episode of Kernel of Truth, I asked Product Manager Brian O’Sullivan (who you’ll remember from our episode about automation) and Principal Engineer Scott Emery to join me in the recording booth and chat about optical networking. We’ll get into topics like forward error correction, the divide between data center networking engineers and optical networking engineers, Voyager and Pink Floyd. Who knew that progressive rock had anything to do with optical networking?? (It doesn’t, really, but we somehow worked it in.)
So tune in and learn why an open packet optical platform is so innovative for optical networking and telco! And make sure to subscribe to the Kernel of Truth podcast so you stay up to date on the open networking revolution — get with the future of networking so you’re not just “Another Brick in the Wall!”
