Edge computing with Red Hat Enterprise Linux

Copy URL

Red Hat® Enterprise Linux® is an operating system (OS) that’s consistent and flexible enough to run enterprise workloads in your datacenter to modeling and analytics at the edge. And the latest release adds an OS deployment option that extends everything protecting Fortune 500 datacenters to all your edge instances.

Red Hat Enterprise Linux puts a consistent layer on inconsistent edge environments, while giving you supported access to open source innovation by representing your requirements upstream and returning with stable updates. IT teams can extend hybrid cloud infrastructures and control hundreds of thousands of nodes running on oil rigs, high-speed trains, ATMs, or airplanes. 

Edge: A TL;DR

Edge computing distributes compute resources to the endpoints of a network, while continuing to centralize resources when possible. It’s a solution to the problem of needing to quickly provide actionable insights based on time-sensitive data.

There are a lot of challenges that come with deploying mini server rooms on lightweight hardware all over the world. Red Hat Enterprise Linux is built for workloads requiring long-term stability and security across a broad ecosystem of certified hardware, software, cloud, and service providers. And we work directly with those vendors to address challenges unique to edge deployments—like harsh operating conditions created by extreme temperatures, dust, and power availability.

Red Hat Enterprise Linux is the foundation for all our software solutions. So when you’re ready to improve your edge deployments with automation or containerized microservices, Red Hat Enterprise Linux is ready as your enterprise open source OS.

Using image builder, IT teams can create custom edge-optimized OS images. Image builder is provided by Red Hat Enterprise Linux and contains everything needed to run edge workloads in specific places. Images can be customized for unique edge workloads, helping keep edge deployments consistent, scalable, more secure, and compliant.

OS image updates are staged in the background of every edge device. This remote device update mirroring allows each install to happen during scheduled downtime or when device owners choose to apply them. It’s an approach that can scale across hundreds of thousands of edge devices and improve workload resiliency by always applying a stable update.

Edge systems using Red Hat Enterprise Linux with rpm-ostree can receive delta updates—a data-reducing package system that only transfers updated bits instead of the entire OS. When an update is pushed, only differences in the bits (known as deltas) are transferred. This reserves networking resources for applications and increases the reliability of edge systems with poor bandwidth or intermittent connectivity.

Create custom health checks using the greenboot framework that automatically run during the startup process. Check to make sure apps, services, and programs running on the OS are operating as they should—across every edge device. And when a health check fails, the OS will revert to the previous state. These intelligent rollbacks keep things operational—improving resiliency and reducing the number of professionals sent into the field when systems do fail.
