# Identifiers: Persistent Cloud Objects

<span style="white-space: pre-wrap;">A </span>**persistent object**<span style="white-space: pre-wrap;"> is an object that retains its state even after the program that created it has terminated, typically by storing its state in a file or database for later retrieval. This allows the object to be reloaded and used again in future program executions.</span>

<span style="white-space: pre-wrap;">A persist cloud object is a persistent object that </span>**lives**<span style="white-space: pre-wrap;"> in one or more cloud systems. </span>

##### Usage

- Reusability: Persistent objects can be reloaded and used across different sessions of a program.
- Serialization: The process of converting an object's state into a format suitable for storage (e.g., converting to bytes).

##### Common Practices

- Serialization: Converting an object to a byte stream for storage.
- Deserialization: Restoring an object from a byte stream.
