The article discusses the use of Terraform's depends_on meta-argument to create explicit dependencies between resources or modules when implicit dependencies cannot be inferred by Terraform. This is useful in scenarios where a resource relies on another resource's behavior but does not access any of that resource's data in its arguments. The article provides examples and use cases for depends_on, as well as considerations to keep in mind when using it. It also mentions Spacelift as a tool for managing Terraform infrastructure and workflows.
