Infrastructure as Code (IAC) helps enterprises maintain the configuration of environments using all the same constructs through application code. Ansible is supported on IBM Power Systems and AIX. IaC is a process of managing and provisioning computer data centers through configuration files rather than physical hardware configuration or interactive configuration tools. Variables and loops come to the rescue. The first thing that should be clarified is the difference between “configuration orchestration” and “configuration management” tools, both of which are considered IaC tools and are included on this list. The post-AIX installation tuning involves activities such as time zone settings, adapter and disk parameter tuning, OS tunable changes, ulimit settings, paging and dump device configuration, Network Time Protocol (NTP) configuration, security hardening, and so on.
