IDG Contributor Network: Are you choosing to lose in a data-driven world?

The Economist has a series of articles right now on the impact of data on business, and pointing out how new data driven companies are rapidly not simply transforming sectors but eliminating competitors. Their argument is that these internet giants are going to require regulators to look at new ways to avoid monopolies and anti-competitive practices. It describes data as a more valuable resource than oil in the modern world.When we look at firms like Amazon, Lyft, Google and what they have done to retail, taxi firms and advertising it is hard to understate just what a dramatic impact these firms have had. Yet fifteen years ago the idea that Amazon would be one of the world’s largest data center service providers would have seemed ridiculous, Amazon are a retailer, what has that to do with data centers? Google are a search engine with some adverts, what have they to do with mobile phones? Apple make some shiny laptops and computers, but mobile phones and speech recognition? Not their thing.To read this article in full or to leave a comment, please click here

Worth Reading: GDPR and Personal Data

With the General Data Protection Regulation (GDPR) becoming effective May 25, 2018, organizations (or rather, organisations) seem to be stressing a bit. Most we speak with are asking, “where do we even start?” or “what is included as personal data under the GDPR?” It is safe to say that these are exactly the questions organizations should be asking, but to know where to start, organizations first need to understand how the GDPR applies to their organization within this new definition for personal data. Without first understanding what to look for, an organization cannot begin to perform data discovery and data mapping exercises, review data management practices and prepare the organization for compliance with the GDPR. —Chris Lippert @ Cloud Security Alliance

My Lexicon: Fexen

Fexen (noun, pl.; pronounced Fex-uhn)

Usage

“Do we have any copper FEXen on those switches?”

Explanation

Fexen is the plural of FEX (the Cisco Nexus Fabric Extender modules). Oh, I know, “FEXes” is just as easy to say, but somehow FEXen seems to work better. Try and use this word in conversation today and see how it feels.

“We have about 20 FEXen distributed around the data center.”

I think you’ll like it.

What the IoT industry can learn from Apple’s revival of the Mac

This post is an excerpt from a talk I gave at the Reality Virtually Hackathon that makes a similar comparison between virtual reality and augmented reality and the Mac. It holds true for the Internet of Things (IoT) and every emerging technology.Many IoT devices makers build on proprietary platforms. Proprietary hardware is an advantage during the emergence of a new platform — until it is not. A proprietary platform protects intellectual property from reverse engineering because the software is tied to the hardware and it can be tuned for performance.Custom-designed hardware performs better — until it doesn’t. For example, when supercomputers, video bridges and CAD simulators were first introduced, all took advantage of custom, proprietary hardware to gain time to market. Now mature products, almost all the supercomputer, video bridge and CAD simulator suppliers use x86 and Nvidia platforms because these they have open ecosystems that add capabilities and value while reducing cost. To read this article in full or to leave a comment, please click here

Cloudflare London Meetup Recap

Cloudflare London Meetup Recap

Cloudflare helps make over 6 million websites faster and more secure. In doing so, Cloudflare has a vast and diverse community of users throughout the world. Whether discussing Cloudflare on social media, browsing our community forums or following Pull Requests on our open-source projects; there is no shortage of lively discussions amongst Cloudflare users. Occasionally, however, it is important to move these discussions out from cyberspace and take time to connect in person.

A little while ago, we did exactly this and ran a meetup in the Cloudflare London office. Ivan Rustic from Hardenize was our guest speaker, he demonstrated how Hardenize developed a Cloudflare App to help build a culture of security. I presented two other talks which included a primer on how the Cloudflare network is architected and wrapped up with a discussion on how you can build and monetise your very own Cloudflare App.

Since we presented this meet-up, I've received a few requests to share the videos of all the talks. You can find all three of the talks from our last London office meet-up in this blog post.

Response: Network Management: Why the CLI?

People get angry when I talk about the death of the CLI for network operations. I’m not the only one: I believe that in today’s network device landscape, the CLI is primarily a tool to promote vendor lock-in by training network engineers to rely on and value it so highly. Yes, devices can be configured […]

IDG Contributor Network: Mixing and matching massively hybrid applications: the future of cloud

A year ago, IDC told us that 68 percent of organizations have adopted cloud for enterprise applications—and that it’s not just about cost, but about revenue increases as well. That study also says that 73 percent of respondents, who spanned both IT and line-of-business users, have a hybrid cloud strategy in place.But when you dig further into those numbers, you’ll find that to most those respondents, “hybrid” means “subscribing to multiple external cloud services.” This can mean some applications in a portfolio run on one cloud while others run on a different cloud. To another 47 percent of those surveyed, “hybrid” means “using a mix of public cloud services and dedicated assets,” which conjures an image of a database running on-site sending data to a web or application server on a public cloud.To read this article in full or to leave a comment, please click here

IDG Contributor Network: SD-WAN will fix business VoIP

“I don’t drink water, period. I live in Los Angeles and the water I get from the tap is lackluster, in terms of quality.”If someone said this, what is the first thought that comes to mind (assuming the person isn’t wearing hemp clothing and has their hair in dreadlocks)?“Have you tried using a water filter?” … is what you and I would probably ask, right?After you read below, this will be the same thing you say when you hear someone say, “VoIP isn’t a good fit for our company because we only have one ISP in the area, and the connection is shaky, at best.”Your response will be “Have you tried using SD-WAN to fix your call quality?”To read this article in full or to leave a comment, please click here

Private networks still the best option for global companies

The rise of SD-WANs has raised an interesting debate. Is the internet good enough to replace a private network for an enterprise WAN?A decade ago, no one would have even considered this, but broadband speeds have increased and more things have moved to the cloud. Also, SD-WAN technology allows for dynamic path selection, which protects the WAN from outages so companies can use multiple broadband connections instead of something like MPLS.Global SD-WAN vendor Aryaka recently examined this question in its “State of SD-WAN Connectivity” report (registration required), which measured and compared data transport from the same pairs of locations using both the internet and over Aryaka’s own global private network. The test run was a randomly created 100 KB file, and connect time and transfer time were captured. The application response time was then calculated as the sum of these two metrics.To read this article in full or to leave a comment, please click here
