Oracle OS Management Hub is the next generation management solution for operating system environments. It provides a centralized management console to monitor and manage updates across your entire environment.
OS Management Hub monitors available Oracle Linux and Microsoft Windows Server environments at scale. From a single view, you gain control of updates over your entire environment, reducing administration and improving efficiency. OS Management Hub is delivered as an Oracle Cloud Infrastructure (OCI) service. It can manage instances in OCI, supported third-party clouds, or on premises in a customer data center.
To use OS Management Hub, an instance registers with the service using a profile which defines initial characteristics for the managed instance such as which software sources (repositories) the system uses, which group it’s a member of, or whether it’s part of a lifecycle environment. Once registered, you can modify the characteristics of the instance. Each instance has an agent that interacts with the OS content on the instance as directed by OS Management Hub. The agent reports data and results back to the service.
OCI instances communicate directly with the OS Management Hub service. On-premises or third-party cloud instances require a management station to act as a network proxy to communicate with the service and act as a local yum and DNF mirror of Oracle Linux software sources (repositories). Only the management station directly communicates with OS Management Hub using port tcp/443, eliminating the need for your managed instances to directly connect with OCI. Instances in your data center send and receive all requests and responses for OS Management Hub through the management station. When instances have a job to update packages or OS content, they receive the content locally from the management station, reducing the amount of bandwidth used for patching instances. All package transfers are local to the data center.
Within OS Management Hub, you control access to Oracle Linux packages and modules by adding only the software sources (repositories) you want to use with the service and defining which software sources an instance can use. You can create custom software sources and use lifecycle environments to further refine content. Creating a group of instances allows you to efficiently monitor and manage updates at scale by applying different update schedules for each group. You can automate updates by creating a scheduled update for a group, individual instance, or all instances in compartment.
