Study Notes
Web Services, REST, and Service-Oriented Architectures
- Web services examples include Microsoft Bing Maps, Google Maps, Amazon Simple Storage Service (Amazon S3), Geonames, DOTS Web services, and Xignite
- Amazon S3 charges are based on a "pay-as-you-go" policy, currently $0.125 per GB for the first 50TB/month of storage used
- Key technologies and standards in Web services include XML, SOAP (Simple Object Access Protocol), WSDL (Web Services Description Language), and UDDI (Universal Discovery, Description, and Integration)
- RESTful Web services emphasize moving away from SOAP-based services towards Representational State Transfer (REST) based communications
- REST services do not require XML, SOAP, WSDL, or UDDI definitions, and are based on an architectural style that specifies constraints for desirable properties
- REST architecture style adopts a client-server architecture, uses a stateless communication protocol, and exchanges representations of resources using a standardized interface and protocol
- Service-Oriented Architectures (SOA) is a business-centric software architecture for building applications that implement business processes as sets of services published at a granularity relevant to the service consumer
- SOA emphasizes flexibility and reusability as key requirements for businesses in a rapidly changing technological landscape
- SOA architecture typically involves three processes: Service Scheduling, Order Processing, and Account Management, each accessing a number of databases
- SOA aims to design loosely coupled and autonomous services that can be combined to provide flexible composite business processes and applications
- Common SOA principles include loose coupling, reusability, and adherence to a communications contract defining information exchange and service description information
- SOA design approach focuses on building Web services for SOA with an emphasis on loose coupling, reusability, and adherence to communication contracts.
