The WordPress REST API allows any programming language to easily access and interact with WordPress content by utilizing a structured and standardized RESTful API. It provides a simple yet extensible way to get data in and out of WordPress through endpoints that correspond to common WordPress content types like posts, pages, users, and comments. The REST API serves as a strong replacement for direct database queries and the admin-ajax PHP endpoint, and can power applications from basic sites to complex microservices.

10. MICROSERVICE
THE MICROSERVICE ARCHITECTURE - IS AN ARCHITECTURAL STYLE
THAT STRUCTURES AN APPLICATION AS A COLLECTION OF
LOOSELY COUPLED SERVICES, WHICH IMPLEMENT BUSINESS
CAPABILITIES.
01
EACH MICROSERVICE IS RELATIVELY SMALL02
IMPROVED FAULT ISOLATION.03
ELIMINATES ANY LONG-TERM COMMITMENT TO A
TECHNOLOGY STACK.
04
CONTINUOUS DELIVERY AND DEPLOYMENT

11. E-COMMERCE APPLICATION

12. DRAWBACKS
01
DEPLOYMENT COMPLEXITY.02
INCREASED MEMORY CONSUMPTION.03
DEVELOPERS MUST DEAL WITH THE ADDITIONAL
COMPLEXITY OF CREATING A DISTRIBUTED SYSTEM.
