Enhancing eBay's Agility with SOA: Project Turmeric and Open Source Innovations

Explore how eBay leverages Service-Oriented Architecture (SOA) through Project Turmeric, enhancing agility and performance. Built on Axis, this initiative facilitates seamless service discovery, monitoring, and management of reusable types while supporting formats like JSON and XML. With a focus on automated testing, governance, and transformation using lightweight frameworks, eBay achieves fast turnaround times and efficient data handling. Join our discussion on overcoming challenges in performance and service enablement, and learn how innovative technologies like Protocol Buffers enhance wire performance.

  1. Agility with Services – The eBay Way

  2. eBay built on SOA TOMMOROW TODAY FUTURE

  3. Project Turmeric – eBay Open source initiative • http://ebayopensource.org • Built on top of Axis • Capabilities • Monitoring • Documentation framework • Policy based authentication • Eclipse plug-ins • Support for variety of formats like JSON, XML, Name Value pair • Tools for managing re-usable types • Type and error libraries

  4. Challenges • Testability • Discover services • Functional testing of services • Performance • Improving performance at the wire level • Low framework overhead (~2 ms) • Transformations • Rest enablement • Fast turn around times

  5. SOA Express • What is SOA Express ? • Marry Governance and testability • Lightweight • Automated • Test across environments • Discover services based on a taxonomy • Service consumer • Service producer • Integrated with SOA Repository

  6. Performance – The problem • Data formats to consider • XML • JSON • Name value • Reduce serialization / de-serialization time • Ensure all formats can be consumed / produced by the same interface • Reduce payload size where possible

  7. Performance – Protocol buffers • Google’s proprietary format • Open source • Define messages through proto files • Smaller packages to transmit over the wire • Faster serialization / de-serialization

  8. Performance – Why Protocol buffers ? • What about avro / thrift / msg-pack ? • Google’s proto objects can be adapted to eBay’s POJOs • Introducing new-message-format-X into the midst is easy • Efficient format for internal clients • 10x improvement in wire time

  9. Transformations – The problem • Clients require different formats • RSS • ATOM • JSON • XML • Rest enable services – SOA and ROA • Flexible and Fast

  10. Transformations – ESB • Format conversion through mediators • Domain specific languages (DSL) define conversion • Transformation framework pluggable at any layer • Dynamic updates to transformations

  11. Transformations – Why ESB ? • Why not XSLT ? • Handle 700 million calls per day • Can scale horizontally • Monitoring with JMX • Blends in with service routing • Introduce additional mediators seamlessly
