Gateway

• Acts as the API gateway as well as loadBalancer for User as well Location-Writer.
• The strategy used is RoundRobbin which is already given for Spring Cloud.
• Another custom implementation for server stickiness is also written which works similar to URL hash load balancing but dependent on the number of instances.
• You can add your custom strategy in the application.yaml file

spring:
    gateway:
      routes:
        - id: location-writer
          uri: lb://location-writer-client
          predicates:

Using lb:// you can use the default strategy which is Round Robbin, to use the custom URL hash loadBalancing replace it with urlhash;

spring:
    gateway:
      routes:
        - id: location-writer
          uri: urlhash://location-writer-client
          predicates:
