Superseded by the Core Platform Team.
We, the Wikimedia Services team, are aiming to shape the Wikimedia service infrastructure with platform services, APIs and tools. We develop scalable APIs with clearly defined Swagger / OpenAPI specs and versioning policies. We automate monitoring, metric reporting and logging. We keep the majority of services simple & stateless by offering general multi-datacenter storage (RESTBase) and change propagation solutions.
Overall, our goal is to make our infrastructure more flexible, robust and efficient by gradually migrating from a monolithic architecture to micro-services.
- RESTBase, the storage & API proxy service behind the Wikimedia REST API. Built using Node.js and Cassandra.
- EventBus, a Kafka-based event distribution solution for asynchronous tasks & cross-service communication.
- ChangeProp, a general change propagation service with support for templated HTTP requests and CDN purging.
- HyperSwitch, a Swagger / OpenAPI spec-based service framework used in RESTBase and ChangeProp.
- Service-runner, a node.js cluster based service runner providing standardized facilities for logging, metrics & rate limiting.
- limitation, an efficient node.js rate limiter library with a Kademlia DHT backend.
