what are end points, contract, address and bindings?
✍: Guest
The above terminologies are the core on which SOA stands. Every service must expose
one or more end points by which the service can be available to the client. End point
consists of three important things where, what and how:
Contract (What)
Contract is an agreement between two or more parties. It defines the protocol how client
should communicate with your service. Technically it describes parameters and return
values for a method.
Address ( Where)
An Address indicates where we can find this service. Address is a URL which points to
the location of the service.
Binding (How)
Bindings determine how this end point can be accessed. It determines how communications
is done. For instance you expose your service which can be accessed using SOAP over
HTTP or BINARY over TCP. So for each of these communications medium two bindings
will be created.
Below figure show the three main components of end point. You can see the stock ticker
is the service class which has an end point hosted on www.soa.com with HTTP and TCP
binding support and using Stock Ticker interface type.
