Description: A redundant API is an API that serves the same function as another API, often for backup or load balancing. This type of API is implemented to ensure availability and continuity of service, especially in critical systems where service interruption can have significant consequences. Redundant APIs allow, in case a primary API fails or becomes inoperative, the redundant API to take its place without affecting end users. This is especially relevant in microservices architectures, where multiple services may depend on a single API to function correctly. Key features of a redundant API include monitoring capability, data synchronization, and error management, allowing for a smooth transition between the primary and redundant APIs. The relevance of redundant APIs lies in their ability to enhance application resilience, ensuring that systems remain operational even in adverse situations. In a world where service availability is crucial, redundant APIs have become a standard practice in modern software development, contributing to the stability and trustworthiness of web-based applications.
