Industry experts expect increased investments in edge capacity to reduce latency and support personalized content delivery and custom security policies.
IDC predicts that the edge computing market worldwide will grow to $250.6 billion by 2024. Dave McCarthy, the firm's research director of edge strategies, thinks edge products and services will power the next wave of digital transformation.
Companies will need to think about how to build out edge capacity with new infrastructure and services. Industry experts predict that companies will start to incorporate edge computing capabilities into the software deployment pipeline and use this infrastructure to support personalized content and streaming services.
Ali Fenn, president of data center consulting firm ITRenew, said that edge computing is fundamentally about how to do compute close to data sources and data users.
"2021 will see major enterprises and tech companies driving towards homogenous, cost-effective infrastructure across these tiers, from public cloud, to private in colos, to modular commercial, and to consumer-proximal," he said. "Winners will look to advanced and modern paradigms for IT and networking, and untether from conventional stacks, racks, and vendors, to deliver plug-and-play, operationally efficient IT, at the lowest possible cost."

Keith Higgins, vice president of digital transformation for Rockwell Automation, describes the edge as the new cloud. He predicts that real-time availability of mission-critical workloads will be vital for companies scaling smart factory initiatives in 2021.
"Edge computing will complement existing cloud infrastructure by enabling real-time data processing where the work takes place: motors, pumps, generators, or other sensors," he said.
The industry will continue to move toward more decentralized compute environments, and the edge will add significant value to digital transformation initiatives.
"By integrating edge functionalities with existing cloud infrastructure, organizations will worry less about logistical IT considerations and, instead, focus on rethinking what's possible in a smart machine," he said.
Here's a preview of what 2021 trends in edge computing will look like.
Moving more services to the edge
Aruba launched its Edge Services Platform (ESP) in June 2020 as an AI-powered, cloud-native platform to automate, unify, and protect the edge.
Aruba CTO Partha Narasimhan said the company defines "the edge" as where the users and the actions are, which could be offices, sports stadiums, or homes. He said that edge computing provides the infrastructure to understand how people use physical spaces as well as to deliver experiences.
"If you create a connectivity layer that is always on, seamless, and secure, that drives participation," he said.
One trend in edge computing that he sees is a push to bring services closer to the connectivity layer to reduce latency.
"Authentication could be centralized but fulfillment will be local," he said. "Companies will have to rethink how to extend zero trust to the edge."
Narasimhan said that Aruba has built its services around a zero-trust model since 2002.
"We don't trust our own access points, they have to authenticate," he said. "Built-in authentication determines what policy gets applied to each device."
Automating some of this process is the only way edge computing will work well, Narasimhan added.
"Policies should be used on demand when and where you need them," he said. "That means not just automation for provisioning from the cloud, but provisioning locally where security rights and policies have to be plumbed in where the user connects."
