# Server Roles

A server-role is a parameter that is mentioned in carbon.xml for wso2carbon based products. Each product has a different default ServerRoles property in its carbon.xml. Default server role values for WSO2Carbon based products are as follows.

- WSO2 AppServer - "ApplicationServer"
- WSO2 BAM - "BusinessActivityMonitor"
- WSO2 BPS - "BusinessProcessServer"
- WSO2 BRS - "BusinessRulesServer"
- WSO2 DSS - "DataServicesServer"
- WSO2 ESB - "EnterpriseServiceBus"
- WSO2 GS - "GadgetServer"
- WSO2 GReg - "GovernanceRegistry"
- WSO2 IS - "IdentityServer"
- WSO2 MS - "MashupServer"

This property value is used for deployment of C-App archives. Generally a C-App consists of a set of resources that is to be deployed in different products. So if an user deploys a C-App in a carbon product all of the resources cannot be deployed in that particular product instance. To sort out which can be deployed and which is can't server-role property is used. When a C-App is being deployed it reads the ServerRoles property in carbon.xml and deploys only the resources which matches the server-role values in there. Here is a example list of C-App resources that map to default server roles.

- ApplicationServer - foo.aar, jax-wx.jar
- EnterpriseServiceBus - proxy.xml
- BusinessProcessServer - my_bpel.zip
- GadgetServer - gadget.xml
