Best micro-service gateways available in spring boot application

 When it comes to choosing the best microservice gateway in a Spring Boot application, there are several popular options available. The choice depends on your specific requirements and preferences. Here are a few notable microservice gateway options for Spring Boot:

1. Spring Cloud Gateway: Spring Cloud Gateway is a lightweight, developer-friendly gateway built on top of Spring Boot and Spring WebFlux. It provides a powerful routing and filtering mechanism, making it easy to build scalable and resilient microservice architectures. Spring Cloud Gateway integrates well with the Spring ecosystem and supports features like rate limiting, circuit breaking, and service discovery.
