What is Serialization?

Serialization is the process of transforming a data object, which includes both code and data stored in a specific memory region, into a sequence of bytes. This process preserves the object's state in a format that can be easily transmitted or stored, allowing it to be transferred to another storage system, application, or destination.

What Is Deserialization?

Deserialization is the process of rebuilding a data structure or object from a byte sequence or string to recreate the object for use. It is the opposite of serialization, where an object or data structure is converted into bytes for storage or transmission. To retrieve the state of an object from a network or persistent storage, a system needs to deserialize it from its raw byte form.

Why Do You Need Deserialization in Distributed Systems?

In distributed systems, objects are frequently shared between different nodes, requiring them to be transmitted over a network. Since objects often contain multiple components, manually writing code to handle each part can be tedious and time-consuming. Serialization provides a standardized way to save and transmit an object's state. Deserialization allows these objects to be reconstructed after being serialized for network transmission, between applications, or through firewalls, and more.
