IDG Contributor Network: Visibility is key for devops and the hybrid cloud

Cloud has undoubtedly become a key component of successful business in recent years, especially when you consider the race to digitally transform. Across the globe, companies are moving their applications and services to the cloud and are consequently reaping the benefits of lower capex and opex as a result.However, with this process, cloud migration is only a beginning for any organization’s digital transformation (DX) journey. If harnessed correctly, cloud is a pillar of innovation for DX, and can be a driving force for new business models and use cases that – even a few years ago – weren’t possible. No one knows this better than devops teams; these teams hold the line when it comes to continuous delivery and deployment, and it therefore stands to reason that devops play a crucial role in the digital transformation journey. In practice however, the decision makers in charge of cloud strategies are rarely those in the bowels of the ship.To read this article in full, please click here

Worth Reading: IPv6 Renumbering == Pain in the …

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

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.

What kinds of sensitive data are we talking about?

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

Kernel of Truth: Optical networking

Subscribe to Kernel of Truth on iTunes, Google Play, Spotify, Castbox and Stitcher!

Click here for our previous episode.

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!”
