What&#-110;s new about Web services?

• Finding services by-what and by-how

  • Traditional distributed computing searched by name

• Looser coupling via less reliance on pre-defined interfaces

  • The growing role of the &#-109;service broker&#-108; to mediate between requestors and providers
  • No single point of failure

• Does not assume single implementation technology

  • Same concepts must scale from simple HTTP POST of XML to robust, reliable MOM

• Web services are starting with an ad hoc view instead of systematic approach

  • Focus is more on shorter term partnerships and collaborations instead of long term relationships
