 It manages resources like virtual machines, DNS records, etc.
 
-It is managed through configuration templates containing info about its tasks and resources. They are saved as *.tf files. If configuration changes, Terraform can detect it and create additional operations to apply those changes.

 ## Heat
-Heat is another orchestration tool used for managing cloud resources. This one is OpenStack exclusive so you can't use it anywhere else. Just like Terraform it is capable of simplifying orchestration operations in your cloud infrastructure.
 
-It also uses configuration templates for the specification of information about resources and tasks. You can manage resources like servers, floating IPs, volumes, security groups, etc. via Heat.
