Chapter 1. Red Hat Device Edge overview
Red Hat Device Edge delivers an enterprise-ready distribution of the Red Hat-led open source community project Red Hat build of MicroShift. MicroShift is a lightweight Kubernetes orchestration solution built from the edge capabilities of OpenShift Container Platform, along with an edge-optimized operating system built from Red Hat Enterprise Linux (RHEL).
1.1. About Red Hat Device Edge
Red Hat Device Edge is for organizations that need small-form-factor edge devices and support for bare metal, virtualized, or containerized applications. Red Hat Device Edge helps address many of the emerging questions around large-scale edge computing at the device edge by incorporating Kubernetes features in a new, smaller, lighter-weight footprint with an edge-optimized Linux operating system built from the world’s leading enterprise Linux platform in RHEL. You can manage Red Hat Device Edge using Red Hat Ansible Automation Platform.

1.1.2. Red Hat Device Edge product release compatibility matrix
Red Hat Enterprise Linux (RHEL) and MicroShift work together as a single solution for device-edge computing. You can update each component separately, but the product versions must be compatible. For example, an update of MicroShift from 4.14 to 4.16 requires a RHEL update. Supported configurations of Red Hat Device Edge use verified releases for each together as listed in the following table:
| RHEL for Edge Version(s) | MicroShift Version | MicroShift Release Status | Supported MicroShift Version→MicroShift Version Updates |
| 9.4 | 4.16 | Generally Available | 4.16.0→4.16.z, 4.14→4.16 and 4.15→4.16 |
| 9.2, 9.3 | 4.15 | Generally Available | 4.15.0→4.15.z, 4.14→4.15 and 4.15→4.16 |
