ColdFusion provides many ways to instantiate CFCs and invoke CFC methods. The following table lists the techniques, including the ColdFusion tags and functions that you use:

Invocation	Description	For more information
cfinvoke tag	Invokes a component method. Can invoke methods of a CFC instance or invoke the methods transiently.	See Invoking CFC methods with the cfinvoke tag.
cfset tag and assignment statements	Invoke methods and access properties of a component instance.	See Using components directly in CFScript and CFML.
URL (HTTP GET)	Transiently invokes a component method by specifying the component and method names in the URL string.	See Invoking component methods by using a URL.
Form control(HTTP POST)	Transiently invokes a component method using the HTML `form` and `input` tags and their attributes.	See Invoking component methods by using a form.
Flash Remoting	ActionScript can transiently invoke component methods.	See Using the Flash Remoting Service.
Web services	The `cfinvoke` tag and CFScript consume web services in ColdFusion. External applications can also consume CFC methods as web services.	See Using Web Services.
