Satellite has previously been the system for provisioning and configuring a new Red Hat Enterprise Linux system, patching and updating multiple RHEL systems across a data center, and managing their life cycles. It was also in charge of each system’s subscription management. Now it’s going to manage RHEL systems in the cloud, as well.
To expand Satellite 6’s reach, Red Hat has shunted some of its own Spacewalk Project’s code out of Satellite and brought in Puppet, Foreman, and other open source systems management modules. That’s one indication of how serious Red Hat is about providing a more up-to-date systems monitoring and management product.
Satellite could previously manage Red Hat Linux on bare metal or virtualized servers under Red Hat’s own Enterprise Virtualization system. Now it can manage RHEL workloads running under the Red Hat OpenStack distribution and the Red Hat OpenShift platform as a service, whether on-premises or in a public cloud — not surprising since the platform and distribution use the default OpenStack hypervisor, KVM, which is owned by Red Hat.
But Satellite can manage bare metal workloads in the cloud, VMware workloads running RHEL under ESX Server, or Amazon Web Services workloads using AWS’ version of Xen, Amazon Machine Image. This makes Satellite more of a cross-hypervisor and cross-cloud management system for the RHEL-intensive shop. It gives Red Hat customers an alternative to the all-VMware vSphere or vCloud data center.
