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) with Red Hat Enterprise Linux (RHEL) and Red Hat Ansible Automation Platform.
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 is a solution for large-scale computing at the device edge that combines MicroShift and an edge-optimized Red Hat Enterprise Linux (RHEL) operating system. MicroShift is a Kubernetes orchestration in a smaller, lighter-weight footprint. Together, these components of Red Hat Device Edge provide all of the benefits of containers deployed to the edge. You can manage Red Hat Device Edge by using Red Hat Ansible Automation Platform.
