Track your infrastructure

[mstakh.i.mom.i]

Plan: Terra-form creates an execution plan that describes the infrastructure that will be created, updated, or removed based on the existing infrastructure and your configuration.

Apply: Once approved, Terra-form executes the suggested operations in the correct order, taking into account all resource dependencies. For example, if you update the properties of a VPC and change the number of VMs in that VPC, Terra-form recreates the VPC before scaling the VMs.

Why Terra-form?
Manage any infrastructure
Find providers for many of the platforms and services you already use in the Terra-form retail email list registry. You can also write your own. Terra-form takes an immutable infrastructure approach, making it easy to update or change your services and infrastructure.


Terra-form creates a plan and asks for your approval before making any changes to your infrastructure. It also tracks your real infrastructure in a state file, which serves as a source of trusted information for your environment. Terra-form uses the state file to determine the changes that need to be made to your infrastructure to match your configuration.

automate changes
Terra-form configuration files are declarative, meaning they describe the end state of your infrastructure. You don't need to write step-by-step instructions to create resources because Terra-form handles the core logic. Terra-form creates a resource graph to define resource dependencies and creates or modifies independent resources in parallel. This allows Terra-form to allocate resources efficiently.
