The next generation of on-premises edge computing technologies for increasingly intelligent services is ramping up, and momentum is growing for both higher throughput computing and networking technologies.
Artificial intelligence (AI), internet of things (IoT), data security, and use cases in manufacturing, health care, transportation, retail, and others rely on ultra-low-latency computing to generate and process data to meet the needs of real-time applications.
For example, in manufacturing, data from sensors analyzed in near–real time can help enable robots to more efficiently run a production line. In health care operations, such data can help medical professionals improve how they share and collaborate on data for patient care and make faster decisions to support positive outcomes. In transportation, real-time data can help enable better flow of traffic and help improve the safety of road conditions. In retail, checkout-free stores or drive-up windows enable a more personalized customer experience. The use cases for low-latency computing are wide and vast.
Thick Edge Servers and Convergence
Edge computing describes servers located outside a data center or telecom central office designed to deliver low-latency computing by offering cloud services close to where data is created. Industry analyst firm Gartner predicts that by 2025, 75 percent of enterprise data will be processed outside of a traditional centralized data center.1
For some use cases, where data volumes exceed the capacity or cost effectiveness to move to a data center, or applications are highly sensitive to latency, edge servers need to be located at or near a customer location. The first on-premises applications to become popular were universal customer premises equipment (uCPE) servers that were cost-effective systems for branch office networking. In this application, single-function networking appliances are replaced by virtualized network functions converged on a single system.
The advent of 5G and the success of cloud technologies has driven the need for “thick edge” servers that provide a cloud computing infrastructure for compute intensive workloads.2
Thick edge servers decentralize data, moving compute resources closer to the source for reduced transport times and very low latency.
Digital transformation empowered by edge computing requires convergence between information technology (IT), operational technology (OT), and communications technologies (CT) at the thick edge. Industry analyst firm IDC predicts that more than 90 percent of new operational processes will be deployed on edge infrastructure by 2024.3 AI applications are a big part of this convergence, as high latencies can hinder applications requiring real-time data processing that are enabled by AI.
Supporting Cloud Security Services
There are numerous proof points that illustrate the value of IT and OT convergence. Incorporating operational insights directly with enterprise business systems can yield better informed decisions for managing costs. For example, traditional OT analysis of equipment maintenance strategies, real-time inventory optimization, and vendor and partner management can yield cost savings when integrated into an IT analytics program.
These systems, however, have historically been siloed and separate, and their convergence requires new attention to security. Gartner notes1 that a challenge introduced by deploying on-premises servers is the potential to increase cybersecurity threats due to an expanded attack surface. This makes delivering cloud security services very important.
Secure access service edge (SASE) is an emerging service that brings together software-defined wide area networks (SDWAN) with network security functions. First deployed as a cloud service, SASE is now deployable from a thick edge cloud server.
SASE security functions may include zero trust network access (ZTNA), firewall as a service (FWaaS), secure web gateway (SWG), and cloud access security broker (CASB). Most functions are delivered “as a service.” SASE uses factors such as identity (person, device type, edge location, etc.), real-time context, and security policies to deliver the security function. Gartner, who coined the term SASE, predicts that by 2024 at least 40 percent of enterprises will have plans to adopt SASE.4
Targeting this application, Supermicro, an Intel® Network Builders ecosystem partner, has collaborated with NetApp to build a high-performance thick edge server. The solution utilizes NetApp storage with AI expertise running on Supermicro’s high-performance, Intel® architecture-based servers.
