IoT’s role in expanding drone use

As faithful readers of TechWatch (love you, Mom) may know, the rollout of many companies’ ambitious drone delivery services has not gone as quickly as promised. Despite recent signs of progress in Australia and the United States—not to mention clever ideas for burger deliveries to cars stuck in traffic—drone delivery remains a long way from becoming a viable option in the vast majority of use cases. And the problem affects many areas of drone usage, not just the heavily hyped drone delivery applications.To read this article in full, please click here

Storage management a weak area for most enterprises

Stop me if you’ve heard this before: Companies are racing to a new technological paradigm but are using yesterday’s tech to do it.I know. Shocking.A survey of more than 300 storage professionals by storage vendor NGD Systems found only 11% of the companies they talked to would give themselves an “A” grade for their compute and storage capabilities.Why? The chief reason given is that while enterprises are rapidly deploying technologies for edge networks, real-time analytics, machine learning, and internet of things (IoT) projects, they are still using legacy storage solutions that are not designed for such data-intensive workloads. More than half — 54% — said their processing of edge applications is a bottleneck, and they want faster and more intelligent storage solutions.To read this article in full, please click here

Kubernetes Operators with Ansible Deep Dive: Part 1

blog_ansible-and-kubernetes-deep-dive-1

This deep dive series assumes the reader has access to a Kubernetes test environment. A tool like minikube is an acceptable platform for the purposes of this article. If you are an existing Red Hat customer, another option is spinning up an OpenShift cluster through cloud.redhat.com. This SaaS portal makes trying OpenShift a turnkey operation.

In this part of this deep dive series, we'll:

  1. Take a look at operators overall, and what they do in OpenShift/Kubernetes.
  2. Take a quick look at the Operator SDK, and why you'd want to use an Ansible operator rather than other kinds of operators provided by the SDK.
  3. And finally, how Ansible Operators are structured and the relevant files created by the Operator SDK.

What Are Operators?

For those who may not be very familiar with Kubernetes, it is, in its most simplistic description - a resource manager. Users specify how much of a given resource they want and Kubernetes manages those resources to achieve the state the user specified. These resources can be pods (which contain one or more containers), persistent volumes, or even custom resources defined by users.

This makes Kubernetes useful for managing resources that don't contain any state (like Continue reading

Reports: As the IoT grows, so do its threats to DNS

The internet of things is shaping up to be a more significant threat to the Domain Name System through larger IoT botnets, unintentional adverse effects of IoT-software updates and the continuing development of bot-herding software.The Internet Corporation for Assigned Names and Numbers (ICANN) and IBM’s X-Force security researchers have recently issued reports outlining the interplay between DNS and IoT that includes warnings about the pressure IoT botnets will put on the availability of DNS systems.More about DNS: DNS in the cloud: Why and why not DNS over HTTPS seeks to make internet use more private How to protect your infrastructure from DNS cache poisoning ICANN housecleaning revokes old DNS security key ICANN’s Security and Stability Advisory Committee (SSAC) wrote in a report that “a significant number of IoT devices will likely be IP enabled and will use the DNS to locate the remote services they require to perform their functions. As a result, the DNS will continue to play the same crucial role for the IoT that it has for traditional applications that enable human users to interact with services and content,” ICANN stated. “The  role of  the  DNS  might  become  even  more  crucial  from  a  security  and  stability Continue reading

How BMW’s new annual fee for Apple CarPlay could define the IoT

Apple calls CarPlay “the ultimate co-pilot.” BMW calls it the “smart and fast way to conveniently use your iPhone features while in your car. ... You can control your iPhone and use apps with the touchscreen display, the iDrive Controller or voice commands.”However you describe it, though, Apple’s CarPlay system suddenly finds itself in the center of what could be a defining conversation about the future of the internet of things (IoT).You see, the German luxury carmaker’s plans to charge $80 a year to access CarPlay have suddenly become the talk of the internet, from tech blogs to car sites. The hue and cry makes CarPlay the perfect illustration of the promise—and the pitfalls—of the IoT.To read this article in full, please click here

Data centers may soon recycle heat into electricity

Waste heat is the scurge of computing. In fact, much of the cost of powering a computer is from creating unwanted heat. That’s because the inefficiencies in electronic circuits, caused by resistance in the materials, generates that heat. The processors, without computing anything, are essentially converting expensively produced electrical energy into waste energy.   It’s a fundamental problem, and one that hasn’t been going away. But what if you could convert the unwanted heat back into electricity—recycle the heat back into its original energy form? The data center heat, instead of simply disgorging into the atmosphere to be gotten rid of with dubious eco-effects, could actually run more machines. Plus, your cooling costs would be taken care of—there’s nothing to cool because you’ve already grabbed the hot air.To read this article in full, please click here
