Web Service or Web API
• Big Web Services (SOAP)
• RESTful Web Services
SOAP/WS-*?
SOAP arguably are:
• Complex• Slow• Heavyweight• Tied to development
tools and libraries• Not supported
universally• Cross-vendor/platform
interoperability NOT perfect
Roy T. FieldingIntroduced REST in 2000
REST?REpresentational State Transfer
