{fas}gears Serving

As seen in the {ref}architecture overview <architecture-overview>, Jina-serve is organized in different layers.

The Serving layer is composed of concepts that allow developers to write their logic to be served by the objects in {ref}orchestration <orchestration> layer.

Two objects belong to this family:

• Executor ({class}~jina.Executor), serves your logic based on docarray data structures.
• Gateway ({class}~jina.Gateway), directs all the traffic when multiple Executors are combined inside a Flow.
