Ribbon is a client side IPC library that is battle-tested in cloud. It provides the following features
To get ribbon binaries, go to maven central. Here is an example to add dependency in Maven:
<dependency>
<groupId>com.netflix.ribbon</groupId>
<artifactId>ribbon</artifactId>
<version>2.2.2</version>
</dependency>
Ribbon comprises of multiple components some of which are used in production internally and some of which were replaced by non-OSS solutions over time. This is because Netflix started moving into a more componentized architecture for RPC with a focus on single-responsibility modules. So each Ribbon component gets a different level of attention at this moment.
More specifically, here are the components of Ribbon and their level of attention by our teams:
Even for the components deployed in production we have wrapped them in a Netflix internal http client and we are not adding new functionality since they’ve been stable for a while. Any new functionality has been added to internal wrappers on top of Ribbon (such as request tracing and metrics). We have not made an effort to make those components Netflix-agnostic under Ribbon.
Recognizing these realities and deficiencies, we are placing Ribbon in maintenance mode. This means that if an external user submits a large feature request, internally we wouldn’t prioritize it highly. However, if someone were to do work on their own and submit complete pull requests, we’d be happy to review and accept. Our team has instead started building an RPC solution on top of gRPC. We are doing this transition for two main reasons: multi-language support and better extensibility/composability through request interceptors. That’s our current plan moving forward.
We currently contribute to the gRPC code base regularly. To help our teams migrate to a gRPC-based solution in production (and battle-test it), we are also adding load-balancing and discovery interceptors to achieve feature parity with the functionality Ribbon and Eureka provide. The interceptors are Netflix-internal at the moment. When we reach that level of confidence we hope to open-source this new approach. We don’t expect this to happen before Q3 of 2016.
