REST services are easily scalable due to several inherent characteristics of the RESTful architecture. Here are the key reasons why REST services are scalable:
Stateless Communication: RESTful services follow a stateless communication model, allowing requests to be processed independently and in parallel.
Resource-Oriented Design: REST APIs are centered around resources, allowing individual resources to be scaled independently.
Cacheability: RESTful services support caching, thereby reducing the load on the server by reusing stored responses.
Load Balancing: Load balancers distribute incoming requests across multiple servers, thus ensuring an even workload distribution.
Horizontal Scaling: REST services can be horizontally scaled by adding more servers or instances to handle increased demand.
Cloud Infrastructure: REST services can leverage cloud platforms with auto-scaling capabilities for efficient resource allocation.
