WebService

  • Web Service is a technology applicable for
    •  computationally distributed problems
    •  including access to large databases
What other technologies were/are available and how they compare with Web Services?
The main buzzwords:
Integration & Standardization & Access by programs

Why to use more than one computer?
  • Distributed resources
  • access to shared data
  • access to shared programs
  • access to CPU (e.g. many desktop PCs together), to memory, to special devices (e.g. printer)
  • Complete independence on the internal implementation

Distributed architecture gives
  • access to distributed resources
  • development encapsulation
  • maintainability, re-usability, legacy-awareness
  • implementation independence
  • requires
  • adding a communication layer between parts
  • synchronization of efforts
  • including such nasty things as distributed garbage collection

Distributed architecture

 
Basic questions are:
  • What kind of protocol to use, and what data to transmit
  • What to do with requests on the server side
