Cloud Storage is a managed service for storing unstructured data. Store any amount of data and retrieve it as often as you like.
With features like Object Lifecycle Management (OLM) and Autoclass you can easily optimize costs with object placement across storage classes. You can enable, at the bucket level, policy-based automatic object movement to colder storage classes based on the last access time. There are no early deletion or retrieval fees, nor class transition charges for object access in colder storage classes.
