A pattern-based policy method for service component architecture (SCA) defines a policy pattern for SCA. The policy pattern includes a plurality of roles and one or more constraints between said plurality of roles. Each of said plurality of roles defines a plurality of intents or policy sets or combination thereof. One or more roles assigned to said one or more SCA components are identified and one or more intents or policy sets or combination thereof associated with said one or more roles are automatically applied to said one or more SCA components. Said one or more intents or policy sets or combination thereof applied to said one or more SCA components are validated based on said one or more constraints.
