Effect of Web Services
Vendors will open proprietary APIs as Web Services
- Access functions that are currently inaccessible
Barriers are low
- HTTP is ubiquitous
- Web servers and XML parsers today are commodities
- No need to install proprietary software
Building block of systems single services accessible through SOAP
- Once service published in UDDI it can be incorporated into other systems
- Becomes implicitly “part” of any application that invokes it
Notes:
Vendors will, increasingly, be opening their proprietary APIs as Web Services giving one access to functions that are currently inaccessible, buried deep inside legacy and/or proprietary code.
The barrier of entry into Web Services is low. HTTP is ubiquitous, web servers and XML parsers today are commodities. There is no need to install proprietary software.
The building block of systems will be single services accessible through SOAP. Once these services are published in UDDI they can be incorporated into other systems, becoming implicitly “part” of any application that invokes them.
