Orchestration means arranging or coordinating multiple systems. It's also used to mean "running the same tasks on a bunch of servers at once, but not necessarily all of them."

Configuration management (CM) is a systems engineering process for establishing and maintaining consistency of a product's performance, functional, and physical attributes with its requirements, design, and operational information throughout its life Configuration management is all about bringing consistency in the infrastructure.
Configuration Orchestration vs Configuration Management
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.
Configuration orchestration tools, which include Terraform and AWS CloudFormation, are designed to automate the deployment of servers and other infrastructure. Configuration management tools like Chef, Puppet, and the others on this list help configure the software and systems on this infrastructure that has already been provisioned.
