10 tech tips to simplify management and automation

Experience consistent and repeatable management of Red Hat® Enterprise Linux®—across your datacenter and cloud environments—by automating manual tasks, standardizing deployment at scale, and simplifying daily administration.

Red Hat Enterprise Linux system roles are a collection of supported roles that provide consistent workflows to streamline the execution of manual tasks. You no longer need to be an expert to manage and configure systems across different Red Hat Enterprise Linux versions. For example, the network system role simplifies configuration across multiple servers with automation.

You can automate configurations across a population of servers by combining multiple roles, such as timesync, kernel setting, and tlog. Using these roles together lets you set the network time protocol (NTP) server settings, kernel tunables for your system workload, and provide terminal session recording across your system population while maintaining common operating environment configurations.

Red Hat Enterprise Linux system roles use Red Hat Ansible® Automation Platform inventory files that break systems into subgroups and allow you to apply roles to certain groups of hosts or apply unique settings to each group of hosts. This gives you more control over what settings are applied where. For example, with the kernel settings role, you could apply 1 set of kernel settings for your database servers and a different set of kernel settings for your file servers.
