Spring Cloud Ribbon Extensions v1.4.5 🚀🔬

❗Must Have❗ Enhance your micro-service testing, maintenance & overall development productivity.

Spring Cloud Ribbon Extensions is a set of load balancing rules that chooses which server to target. It comes with handy features for easy integration, configuration and customization.

Requirements

java 8
spring boot 1.5.x or newer
spring cloud ribbon.
spring cloud Daslton-SR3 or newer.

Compatibility

spring cloud eureka.
spring cloud feign.
spring cloud zuul.
spring cloud hystrix.
spring and java executors.
spring stomp.
jms.

Features

Routing Rules.

Zone Affinity

@EnableRibbonZoneAffinity: Enables routing to the same zone: see the tests for concrete usage and configurations.

Designed mainly for micro-services that should calls others in the same zone.

Favorite Zone 💎

@EnableRibbonFavoriteZone: Enables routing to a favorite zone: see the tests for concrete usage and configurations.

Designed mainly for testing a micro-service among an existing micro-service architecture without disruption. This is the feature that triggered this project.

Strict Metadata Matcher

@EnableRibbonStrictMetadataMatcher: Enables routing to servers that have a set of metadata: see the tests for concrete usage and configurations.

Designed to target a specific micro-service that holds a point to point connection with an external system (like FIX,...)

Requires Eureka.

Dynamic Metadata Matcher 💎

@EnableRibbonDynamicMetadataMatcher: Enables routing against a dynamic key: see the tests for concrete usage and configurations.

Designed to target a specific micro-services that holds multiple point to point connections with many external systems (like FIX,...)

Requires Eureka.

Context Propagation 💎

@EnableContextPropagation: Enables sharing the execution context through all the micro-services: see the tests for concrete usage and configurations.

Designed to propagate the execution context across the micro-services architecture.

What does it support:

Transport: http, jms, stomp.
Async: java, spring, Hystrix.
Zuul

⚠️You should use only lower case key names (http header limitation).

Combine Favorite Zone & Context Propagation ✨

Eureka:exclamation: Let's enter a world of easy development and testing with micro-service architecture.

Developers are able to deploy & debug their own micro-service and get back any request they have initiated disregarding the entry point and without being annoyed by the requests they have not initiated.
Deploying in multi region-and let our clients (that have no knowledge of eureka, ribbon, zuul) choose the zone they prefer to target.
And other things that I have not thought about...
