One of the ways to describe software architecture is to express its configuration
in executable and therefore repeatable form – infrastructure as code. Tools that
are often used for this purpose (for example, Puppet, Ansible, Chef) are not
utilized to their full potential. Provided abstractions, extension points,
existing modules are ignored by turning provisioning software into just a fancy
file copying utility. Software configuration has a variety of frequently
appearing patterns and ready-made abstractions to better communicate the intent
of the architecture described in the form of infrastructure as code. The intent
of this presentation is to provide summary of such patterns.
