When you get on a cruise ship or go to a major resort, there’s a lot happening behind the scenes. Thousands of people work to create amazing, memorable experiences, often out of sight. And increasingly, technology helps them make those experiences even better.

We sat down recently with Todd Heard, VP of Infrastructure at Carnival Corporation, to find out how technology like Docker helps them create memorable experiences for their guests. Todd and some of his colleagues worked at Disney in the past, so they know a thing or two about memorable experiences.

Here’s what he told us. You can also catch the highlights in this 2 minute video:

On Carnival’s Mission

Our goal at Carnival Corporation is to provide a very personalized, seamless, and customized experience for each and every guest on their vacation. Our people and technology investments are what make that possible. But we also need to keep up with changes in the industry and people’s lifestyles.

On Technology in the Travel Industry and Customized Guest Experiences

One of the ironies in the travel industry is that everybody talks about technology, but the technology should be invisible Continue reading

BrandPost: Westcon-Comstor Builds a more Visible WAN

For Michael Soler, a senior infrastructure manager at Westcon-Comstor, a major IT distributor, moving to a software-defined wide-area network (SD-WAN) was as much about taking control of the network as it was about saving money.The move accomplished both, according to Soler. “It’s been a very successful story,” says Soler. “We have gained visibility, and this means control. I can see which users are using which applications, and we can look at bandwidth. We wanted to save money and we greatly succeeded.”Of course, there is more to the story than that. Soler says moving to an SD-WAN platform, built by Silver Peak, accomplished many goals at once. These included:To read this article in full, please click here

Celebrating National Cybersecurity Awareness Month

Every October, we mark National Cybersecurity Awareness Month. From the U.S. Department of Homeland Security website, “Held every October, National Cybersecurity Awareness Month (NCSAM) is a collaborative effort between government and industry to raise awareness about the importance of cybersecurity and to ensure that all Americans have the resources they need to be safer and more secure online.”

We believe in an Internet that is open, globally connected, secure, and trustworthy. Our work includes improving the security posture of producers of Internet of Things (IoT) devices, ensuring encryption is available for everyone and is deployed as the default, working on time security, routing security through the MANRS initiative, and fostering collaborative security.

The Online Trust Alliance’s IoT Trust Framework identifies the core requirements manufacturers, service providers, distributors/purchasers, and policymakers need to understand, assess, and embrace for effective security and privacy as part of the Internet of Things. Also check out our Get IoT Smart pages for get more consumer-friendly advice on IoT devices.

Much of OTA’s work culminates in the Online Trust Audit & Honor Roll, which recognizes excellence in online consumer protection, data security, and responsible privacy practices. Since that report’s release in April Continue reading

Undercover Apps You’ve Never Heard Of (Until Now)

With so many new apps springing up constantly, some very useful apps tend not to get the attention they deserve and become undercover apps that are used by a very few who happen to discover them and their usefulness. Here are some undercover apps you’ve probably never heard of until now, but may be worth learning a little more about.

4 Weirdly Helpful Undercover Apps

Vayable

Vayable is an app that allows you to enhance your travel or vacation experiences. This app is great for anyone visiting an unfamiliar area who wants to experience the area in a way only locals can. This app allows you to contact a local resident that will allow you to see sights or share experiences that are not listed in vacation brochures, such as having someone take you around to see the best street are in San Francisco and maybe even get to watch some local street artists at work.

Rover

Another great little known app for people who travel is Rover. If you have a dog and need to leave him behind when you travel for business or even vacation and don’t like the idea of placing your beloved pet into a cold Continue reading

Top Questions: Containers and VMs Together

We had a great turnout to our recent webinar “Demystifying VMs, Containers, and Kubernetes in the Hybrid Cloud Era” and tons of questions came in via the chat — so many that we weren’t able to answer all of them in real-time or in the Q&A at the end. We’ll cover the answers to the top questions in two posts (yes, there were a lot of questions!).

First up, we’ll take a look at IT infrastructure and operations topics, including whether you should deploy containers in VMs or make the leap to containers on bare metal. 

VMs or Containers?

Among the top questions was whether users should just run a container platform on bare metal or run it on top of their virtual infrastructure — Not surprising, given the webinar topic.

  • A Key Principle: one driver for containerization is to abstract applications and their dependencies away from the underlying infrastructure. It’s our experience that developers don’t often care about the underlying infrastructure (or at least they’d prefer not to). Docker and Kubernetes are infrastructure agnostic. We have no real preference.
  • The goal – yours and ours: provide a platform that developers love to use, AND provide Continue reading

New Content: Azure Networking and Automation Source-of-Truth

Last week I covered network security groups, application security groups and user-defined routes in the second live session of Azure Networking webinar.

We also had a great guest speaker on the Network Automation course: Damien Garros explained how he used central source-of-truth based on NetBox and Git to set up a network automation stack from the grounds up.

Recordings are already online; you’ll need Standard ipSpace.net Subscription to access the Azure Networking webinar, and Expert ipSpace.net Subscription to access Damien’s presentation. Azure Networking webinar is also part of our new Networking in Public Clouds online course.

In-toto: providing farm-to-table guarantees for bits and bytes

in-toto: providing farm-to-table guarantees for bits and bytes Torres-Arias et al., USENIX Security Symposium 2019

Small world with high risks did a great job of highlighting the absurd risks we’re currently carrying in many software supply chains. There are glimmers of hope though. This paper describes in-toto, and end-to-end system for ensuring the integrity of a software supply chain. To be a little more precise, in-toto secures the end-to-end delivery pipeline for one product or package. But it’s only a small step from there to imagine using in-toto to also verify the provenance of every third-party dependency included in the build, and suddenly you’ve got something that starts to look very interesting indeed.

In-toto is much more than just a research project, it’s already deployed and integrated into a number of different projects and ecosystems, quietly protecting artefacts used by millions of people daily. You can find the in-toto website at https://in-toto.io.

In-toto has about a dozen different integrations that protect software supply chains for millions of end-users.

  • If you install a Debian package using apt, in-toto is protecting it.
  • If you use kubesec to analyze your Kubenetes configurations, in-toto is protecting it
  • If you use the Continue reading

Learn more about Workers Sites at Austin & San Francisco Meetups

Last Friday, at the end of Cloudflare’s 9th birthday week, we announced Workers Sites.

Now, using the Wrangler CLI, you can deploy entire websites directly to the Cloudflare Network using Cloudflare Workers and Workers KV. If you can statically generate the assets for your site, think create-react-app, Jekyll, or even the WP2Static plugin, you can deploy it to our global network, which spans 194 cities in more than 90 countries.

If you’d like to learn more about how it was built, you can read more about this in the technical blog post. Additionally, I wanted to give you an opportunity to meet with some of the developers who contributed to this product and hear directly from them about their process, potential use cases, and what it took to build.

Check out these events. If you’re based in Austin or San Francisco (more cities coming soon!), join us on-site. If you’re based somewhere else, you can watch the recording of the events afterwards.

“What’s your IPv6 strategy?”

"What's your IPv6 strategy?"

For many in enterprise networking, IPv6 is just a distant memory of a tedious mandatory training a few years back. Weird addresses, over-eager trainer, stories about v6 adoption that never came true. Why then for the last couple of years have I been presenting to Aruba audiences about IPv6 adoption? While many network engineers maybe unaware, IPv6 is very much upon us and numerous times this year I've heard from various sources, 'What's your IPv6 strategy?'

It's alive!

Turning back the clock a few years and IPv6 was for the specialist or for university campuses eager to deploy the latest technology. Live deployments of IPv6 outside of academia were largely unheard of. Then came the ISP deployments across the global, in roughly 2015-2017. Now IPv6 was out in the wild and in our homes. It was this transition of IPv6 from the textbook to the live networks around us that changed the nature of the protocol and breathed life into those 128 bits.
But this was a largely silent change. No big fanfare, hashtags or broadsheet ads. No proliferation of start-ups hunting VC money. No LinkedIn profiles being updated with 'IPv6 thought-leader'. For that reason I feel many network Continue reading

Flow metrics with Prometheus and Grafana

The Grafana dashboard above shows real-time network traffic flow metrics. This article describes how to define and collect flow metrics using the Prometheus time series database and build Grafana dashboards using those metrics.
Prometheus exporter describes an application that runs on the sFlow-RT analytics platform that converts real-time streaming telemetry from industry standard sFlow agents. Host, Docker, Swarm and Kubernetes monitoring describes how to deploy agents on popular container orchestration platforms.

The latest version of the Prometheus exporter application adds flow export.

Innovation Exercises to Increase Your Personal Creativity

To advance in most careers these days you need to be creative and able to think outside of the box, but this is easier said than done. As children, we freely use our imagination and our creativity, but as we mature we are often asked to leave our imagination behind in order to perform in the “real world.” So how do you get back that personal creativity as an adult? Here are some innovation exercises that will help you increase your personal creativity.

5 Innovation Exercises to Boost Brain Power and Creativity

Try Looking at Things from a New Perspective

Over time, it becomes ingrained in us to look at things from one given perspective; however, learning to look at things from a different perspective may help us to see things in a different light and spur creativity. For example, if you normally view that tree in your backyard from a distance, why not sit under its branches and look up. Close your eyes, inhale deeply, and touch its leaves and branches, “seeing” it not through your eyes but through your sense of touch or smell. This will help you to see the tree more creatively than by simply Continue reading
