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...
