1What is a Terraform module?
What is a Terraform module?
Відповідь
A Terraform module is a reusable container of resources and infrastructure logic. It allows encapsulating a set of related resources and reusing them across different projects or environments. Modules accept input variables and can expose outputs to enable composition and chaining between modules.
2What is the main difference between a workspace and a module?
What is the main difference between a workspace and a module?
Відповідь
Workspaces allow managing multiple instances of the same code with separate state files, while modules encapsulate reusable code. A workspace serves to isolate states for different environments, whereas a module serves to reuse infrastructure logic. Workspaces share the same code but different states, modules share code across projects.
3What is the main advantage of using a remote backend like S3 instead of local state?
What is the main advantage of using a remote backend like S3 instead of local state?
Відповідь
The remote backend enables state sharing between team members and guarantees deployment consistency. With local state, each developer has their own copy, creating conflicts and inconsistencies. The remote backend also offers state locking to prevent concurrent modifications and facilitates collaboration by centralizing the source of truth.
