What is a digital twin? [And how it’s changing IoT, AI and more]

Digital twin technology has moved beyond manufacturing and into the merging worlds of the Internet of Things, artificial intelligence and data analytics.As more complex “things” become connected with the ability to produce data, having a digital equivalent gives data scientists and other IT professionals the ability to optimize deployments for peak efficiency and create other what-if scenarios.[ Now read 20 hot jobs ambitious IT pros should shoot for. ] What is a digital twin? A digital twin is a digital representation of a physical object or system. The technology behind digital twins has expanded to include large items such as buildings, factories and even cities, and some have said people and processes can have digital twins, expanding the concept even further. The idea first arose at NASA: full-scale mockups of early space capsules, used on the ground to mirror and diagnose problems in orbit, eventually gave way to fully digital simulations.To read this article in full, please click here

Software-Defined and Cloud-Native Foundations for 5G Networks

Cloud-Native Foundations AvidThink (formerly SDxCentral Research) has put together a research brief that explains the infrastructure changes required, and the role that software-defined and cloud-native technologies will play in the 5G world, including supporting network slicing.

DRaaS options grow, but no one size fits all

AutoNation spent years trying to establish a disaster recovery plan that inspired confidence. It went through multiple iterations, including failed attempts at a full on-premises solution and a solution completely in the cloud. The Fort Lauderdale, Fla.-based auto retailer, which operates 300 locations across 16 states, finally found what it needed with a hybrid model featuring disaster recovery as a service.“Both the on-premises and public cloud disaster recovery models were expensive, not tested often or thoroughly enough, and were true planning and implementation disasters that left us open to risk,” says Adam Rasner, AutoNation’s vice president of IT and operations, who was brought on two years ago in part to revamp the disaster recovery plan. The public cloud approach sported a hefty price tag: an estimated $3 million if it were needed in the wake of a three-month catastrophic outage. “We were probably a little bit too early in the adoption of disaster recovery in the cloud,” Rasner says, noting that the cloud providers have matured substantially in recent years.To read this article in full, please click here

DARPA explores new computer architectures to fix security between systems

Solutions are needed to replace the archaic air-gapping of computers used to isolate and protect sensitive defense information, the U.S. Government has decided. Air-gapping, used often now, is the practice of physically isolating data-storing computers from other systems, computers, and networks. It theoretically can’t be compromised because there is nothing between the machines — there are no links into the machines; they’re removed.However, many say air-gapping is no longer practical, as the cloud and internet takes a hold of massive swaths of data and communications.“Keeping a system completely disconnected from all means of information transfer is an unrealistic security tactic,” says Defense Advanced Research Projects Agency (DARPA) on its website, announcing an initiative to develop completely new hardware and software that will allow defense communications to take place securely among myriad existing systems, networks, and security protocols.To read this article in full, please click here

Internet Society Botswana Chapter Hosts Webinar on the Internet of Things

The Internet of Things (IoT) is upon us. The exponential advancements are fast becoming a reality and Africa is a part of the current wave. On 13 December 2018, the Internet Society Botswana Chapter held an Internet of Things webinar at the University of Botswana Library to discuss local IoT-related implications. In attendance were approximately seventy-five individuals, including members of the public, academia, the developer community, and students.

A quick Internet search reveals that IoT can be synonymous with tracking and monitoring systems, wearables, and smart homes. These may not be relatable in the African context, but IoT prospective usage in farming, irrigation, and utilities management brings it home and introduces the possibilities of IoT being used to provide solutions that fit Africa’s needs. It therefore becomes important to implement a multistakeholder approach where governments and regulators provide high speed connectivity, infrastructure, and the right policies to foster local innovation.

The interactive session offered the participants an appreciation of the current IoT situation in Botswana. A remote presentation by Steve Olshansky, Internet technology program manager at the Internet Society explained the Internet Society’s view of IoT, the  OTA IoT Trust by Design Framework, and why we should ensure Continue reading

What programming languages rule the Internet of Things?

As the Internet of Things (IoT) continues to evolve, it can be difficult to track which tools are most popular for different purposes. Similarly, trying to keep tabs on the relative popularity of programming languages can be a complex endeavor with few clear parameters. So, trying to figure out the most popular programming languages among the estimated 6.2 million IoT developers (in 2016) seems doubly fraught — but I’m not going to let that stop me.To read this article in full, please click here
