Whatisserviceorientedarchitecture(SOA)

•  ArchitecturalpaSernwheresystemsprovideservicestoothersystemsviastandardprotocols.

•  Product,vendor,technologyindependent.•  Boundariesareexplicit.•  Servicesareautonomous.•  Servicesshareschemaandcontract,notclasses.•  PolicyDriven.

WhySOA?

•  Loosecouplingofservices.•  Easytomaintain.•  Re-usability.•  Flexibility.•  Agility.•  Scalability.•  NewbusinessopportuniAes.
