Web Service Interface Protocol

A Web Service Interface Protocol is a web protocol that defines service interaction through standardized interfaces (for enabling distributed system communication and service integration).

• AKA: Web API Protocol.
• Context:
  • It can implement Service Styles through architectural patterns:
    • It can support REST Architecture through resource-based interface.
    • It can enable SOAP Architecture through message-based interface.
    • It can provide GraphQL Architecture through query-based interface.
    • It can facilitate gRPC Architecture through procedure-based interface.
  • It can handle Service Operations through protocol methods:
    • It can process Data Retrieval through read operation.
    • It can manage Data Modification through write operation.
    • It can support Data Deletion through delete operation.
    • It can execute Data Creation through create operation.
  • It can enable Protocol Features through service capabilitys:
    • It can ensure Service Security through authentication mechanism.
    • It can provide Service Discovery through registry system.
    • It can maintain Service Monitoring through metrics collection.
  • ...
  • It can range from being a Simple Service Protocol to being an Enterprise Service Protocol, depending on its protocol complexity.
  • It can range from being a Lightweight Protocol to being a Full-Featured Protocol, depending on its feature set.
  • ...
  • It can integrate with Service Registry for service discovery.
  • It can connect to Service Gateway for request routing.
  • It can support Service Mesh for service orchestration.
  • ...
• Example(s):
  • Resource-oriented Protocols, such as:
    • REST API Protocols, such as:
      • RESTful HTTP for web resource manipulation.
      • REST over HTTPS for secure resource access.
    • OData Protocol for standardized REST interface.
  • Message-oriented Protocols, such as:
    • SOAP Protocols, such as:
      • SOAP over HTTP for web service messaging.
      • SOAP over JMS for enterprise messaging.
    • XML-RPC Protocol for remote procedure call.
  • Query-oriented Protocols, such as:
    • GraphQL Protocol for flexible data query.
    • SPARQL Protocol for semantic data query.
  • RPC-oriented Protocols, such as:
    • gRPC Protocol for high performance RPC.
    • Apache Thrift for cross-language RPC.
  • ...
• Counter-Example(s):
  • Web Browser Protocol, which focuses on user interface rather than service interface.
  • Database Protocol, which handles data storage instead of service communication.
  • File Transfer Protocol, which manages file transfer rather than service interaction.
  • Message Queue Protocol, which implements message broker pattern instead of service interface.
  • Network Protocol, which handles data transmission rather than service definition.
