Spring Cloud Ribbon Extensions

Requirements

• spring cloud eureka.

Features

Routing Rule

Favorite Zone Routing.

use @EnableRibbonFavoriteZone to enable routing to a favorite zone.

Strict Metadata Routing

use @EnableRibbonStrictMetadataMatcher to enable routing to servers that have the same context metadata.

Context Propagation

use @EnableRibbonContextPropagation to enable desired http headers flowing between all your micro-services.

Combine Favorite Zone Routing & Context Propagation

Eureka!

• We are able to test our micro-service without running all the application services only by adding our zone to http request header.
• We are able to deploy in multi region and let our clients (that have no knowledge of eureka, ribbon, zuul) choose the nearest zone.
