Automation and Orchestration differ in that automation relates to codifying tasks, whereas orchestration relates to codifying processes. Automation is the process of converting manual tasks into executable scripts or programs that can be run by machines or software agents. Orchestration is the process of coordinating multiple automated tasks into a coherent workflow that achieves a desired outcome or goal. Orchestration can also involve integrating different systems, tools, and services through web service interactions such as XML and JSON.
