Retail’s evolution depends on edge computing


“When you think about a retailer that has 2,000 locations across the country, it’s too expensive to deploy on-premises data processing and analytics for every single location, so that’s where edge computing can be a huge boon,” says Paul Savill, senior vice president of product management and services at technology company Lumen, who points out that edge computing is designed to work in tandem with cloud. “Edge nodes combine hardware-driven computational power with software-defined networking capabilities to connect it to the public cloud,” he explains. “From one centralized node in one market area, say, the size of Denver, edge computing can serve many more retail locations within five milliseconds.”

Opportunities outweigh challenges

Shivkumar Krishnan, head of stores engineering at Gap, says the biggest challenge to making edge computing a reality in retail is legacy infrastructure. “As an end user on the cloud, it’s much easier to upgrade, since you can simply push a button and shut down or replace a virtual machine. In retail, it’s more of a logistics problem,” he explains. When setting up the first time, each location needs to connect its devices to the edge, which may need to be done at night, when customers aren’t in the store. And with vendors working on-site, store security staff as well as the manager will need to be on hand. “It really becomes more of a logistics challenge to figure out the availability of everyone,” Krishnan says. “And the process needs to be repeated for each of our 2,500 stores.” In the cloud, one push of a button can deploy hundreds of servers.

Data security is also an inevitable challenge when it comes to the internet of things and other digital devices. “The more you concentrate information in a location, the more you have to worry about protecting that, and the riskier that becomes in terms of creating a single spot that can be penetrated, and information stolen,” says Savill. But edge computing supported at nodes in nearby data centers and connecting to the public cloud are generally more secure and reliable than what a retailer could do on its own. That’s because edge providers, much like public cloud providers, are providing cybersecurity from a central location, on a mass scale, so they have visibility into what the threats are and how they’re affecting their customers, says Savill.

That said, the benefits and opportunities of the edge far outweigh potential challenges. “One of our biggest use cases for edge computing is at the point of sale, where we process millions of transactions,” Krishnan explains. From the store to the cloud, there are many failure points—switches, routers, the telecom circuit, and cloud providers. “The edge gives us a high level of redundancy to process all transactions at the store itself and fall back to the cloud if the edge fails,” he says.

“The edge gives us the full redundancy to process all transactions at the store itself and fall back to the cloud if the edge fails.”

Gap has invested in edge servers over the past few years, says Krishnan, as part of an overall platform using the latest technologies such as microservices, cloud computing, streaming services, and a DevOps approach to engineering. “Now, with our platform, we can build, validate, and deploy applications with rapid turnarounds—all within the same day,” he says. “I can remotely monitor and manage the majority of our over 100,000 devices. Our sales associates use iPads that give us the ability to build native mobile user experiences that are intuitive.”

While Gap was early to the edge computing game, the challenge is keeping up with the latest and most advanced technologies, as with any technology adoption. Today’s edge servers have built-in graphic processing units, network routers, and broadband technology 5G, “all packaged in small-footprint devices that are built from the ground up for advanced machine learning,” he says. “Hopefully, we will catch the next iteration of these advancements and leapfrog others who get them now.”

The hunter-gatherer groups at the heart of a microbiome gold rush

The hunter-gatherer groups at the heart of a microbiome gold rush


The first step to finding out is to catalogue what microbes we might have lost. To get as close to ancient microbiomes as possible, microbiologists have begun studying multiple Indigenous groups. Two have received the most attention: the Yanomami of the Amazon rainforest and the Hadza, in northern Tanzania. 

Researchers have made some startling discoveries already. A study by Sonnenburg and his colleagues, published in July, found that the gut microbiomes of the Hadza appear to include bugs that aren’t seen elsewhere—around 20% of the microbe genomes identified had not been recorded in a global catalogue of over 200,000 such genomes. The researchers found 8.4 million protein families in the guts of the 167 Hadza people they studied. Over half of them had not previously been identified in the human gut.

Plenty of other studies published in the last decade or so have helped build a picture of how the diets and lifestyles of hunter-gatherer societies influence the microbiome, and scientists have speculated on what this means for those living in more industrialized societies. But these revelations have come at a price.

A changing way of life

The Hadza people hunt wild animals and forage for fruit and honey. “We still live the ancient way of life, with arrows and old knives,” says Mangola, who works with the Olanakwe Community Fund to support education and economic projects for the Hadza. Hunters seek out food in the bush, which might include baboons, vervet monkeys, guinea fowl, kudu, porcupines, or dik-dik. Gatherers collect fruits, vegetables, and honey.

Mangola, who has met with multiple scientists over the years and participated in many research projects, has witnessed firsthand the impact of such research on his community. Much of it has been positive. But not all researchers act thoughtfully and ethically, he says, and some have exploited or harmed the community.

One enduring problem, says Mangola, is that scientists have tended to come and study the Hadza without properly explaining their research or their results. They arrive from Europe or the US, accompanied by guides, and collect feces, blood, hair, and other biological samples. Often, the people giving up these samples don’t know what they will be used for, says Mangola. Scientists get their results and publish them without returning to share them. “You tell the world [what you’ve discovered]—why can’t you come back to Tanzania to tell the Hadza?” asks Mangola. “It would bring meaning and excitement to the community,” he says.

Some scientists have talked about the Hadza as if they were living fossils, says Alyssa Crittenden, a nutritional anthropologist and biologist at the University of Nevada in Las Vegas, who has been studying and working with the Hadza for the last two decades.

The Hadza have been described as being “locked in time,” she adds, but characterizations like that don’t reflect reality. She has made many trips to Tanzania and seen for herself how life has changed. Tourists flock to the region. Roads have been built. Charities have helped the Hadza secure land rights. Mangola went abroad for his education: he has a law degree and a master’s from the Indigenous Peoples Law and Policy program at the University of Arizona.

The Download: a microbiome gold rush, and Eric Schmidt’s election misinformation plan


Over the last couple of decades, scientists have come to realize just how important the microbes that crawl all over us are to our health. But some believe our microbiomes are in crisis—casualties of an increasingly sanitized way of life. Disturbances in the collections of microbes we host have been associated with a whole host of diseases, ranging from arthritis to Alzheimer’s.

Some might not be completely gone, though. Scientists believe many might still be hiding inside the intestines of people who don’t live in the polluted, processed environment that most of the rest of us share. They’ve been studying the feces of people like the Yanomami, an Indigenous group in the Amazon, who appear to still have some of the microbes that other people have lost. 

But there is a major catch: we don’t know whether those in hunter-gatherer societies really do have “healthier” microbiomes—and if they do, whether the benefits could be shared with others. At the same time, members of the communities being studied are concerned about the risk of what’s called biopiracy—taking natural resources from poorer countries for the benefit of wealthier ones.

Navigating a shifting customer-engagement landscape with generative AI

Navigating a shifting customer-engagement landscape with generative AI


A strategic imperative

Generative AI’s ability to harness customer data in a highly sophisticated manner means enterprises are accelerating plans to invest in and leverage the technology’s capabilities. In a study titled “The Future of Enterprise Data & AI,” Corinium Intelligence and WNS Triange surveyed 100 global C-suite leaders and decision-makers specializing in AI, analytics, and data. Seventy-six percent of the respondents said that their organizations are already using or planning to use generative AI.

According to McKinsey, while generative AI will affect most business functions, “four of them will likely account for 75% of the total annual value it can deliver.” Among these are marketing and sales and customer operations. Yet, despite the technology’s benefits, many leaders are unsure about the right approach to take and mindful of the risks associated with large investments.

Mapping out a generative AI pathway

One of the first challenges organizations need to overcome is senior leadership alignment. “You need the necessary strategy; you need the ability to have the necessary buy-in of people,” says Ayer. “You need to make sure that you’ve got the right use case and business case for each one of them.” In other words, a clearly defined roadmap and precise business objectives are as crucial as understanding whether a process is amenable to the use of generative AI.

The implementation of a generative AI strategy can take time. According to Ayer, business leaders should maintain a realistic perspective on the duration required for formulating a strategy, conduct necessary training across various teams and functions, and identify the areas of value addition. And for any generative AI deployment to work seamlessly, the right data ecosystems must be in place.

Ayer cites WNS Triange’s collaboration with an insurer to create a claims process by leveraging generative AI. Thanks to the new technology, the insurer can immediately assess the severity of a vehicle’s damage from an accident and make a claims recommendation based on the unstructured data provided by the client. “Because this can be immediately assessed by a surveyor and they can reach a recommendation quickly, this instantly improves the insurer’s ability to satisfy their policyholders and reduce the claims processing time,” Ayer explains.

All that, however, would not be possible without data on past claims history, repair costs, transaction data, and other necessary data sets to extract clear value from generative AI analysis. “Be very clear about data sufficiency. Don’t jump into a program where eventually you realize you don’t have the necessary data,” Ayer says.

The benefits of third-party experience

Enterprises are increasingly aware that they must embrace generative AI, but knowing where to begin is another thing. “You start off wanting to make sure you don’t repeat mistakes other people have made,” says Ayer. An external provider can help organizations avoid those mistakes and leverage best practices and frameworks for testing and defining explainability and benchmarks for return on investment (ROI).

Using pre-built solutions by external partners can expedite time to market and increase a generative AI program’s value. These solutions can harness pre-built industry-specific generative AI platforms to accelerate deployment. “Generative AI programs can be extremely complicated,” Ayer points out. “There are a lot of infrastructure requirements, touch points with customers, and internal regulations. Organizations will also have to consider using pre-built solutions to accelerate speed to value. Third-party service providers bring the expertise of having an integrated approach to all these elements.”
