The translated data: OpenTF is an open-source tool designed for securely and efficiently building, altering, and versioning cloud infrastructure. It offers features such as Infrastructure as Code, execution plans, resource graphs, and change automation, enabling developers to manage cloud infrastructure in a declarative manner, enhancing management efficiency and reducing operational risks. Key functionalities of OpenTF include Infrastructure as Code, execution plans, resource graphs, and change automation. By describing infrastructure configurations with a high-level configuration syntax, version control and reusability are facilitated. Generating execution plans displays the sequence of operations, preventing surprises. Resource graphs allow for the parallel creation and modification of resources, efficiently constructing infrastructure.
