Providing Support for a New IaaS Provider

The IaaS provider implementation (e.g., org.wso2.carbon.stratos.iaas.VcloudIaas.java)should extend the Iaas abstract class provided by Cloud Controller.
Wrap the implementation in an OSGi bundle. It should be a fragment bundle of the Cloud Controller. This via your bundle's pom file.
Add the following line as a configuration instruction of maven bundle plugin:
```
<Fragment-Host>{symbolic-name-of-cloud-controller}</Fragment-Host>
```
```
{symbolic-name-of-cloud-controller} = org.wso2.carbon.stratos.cloud.controller
```
Add the cloud-controller component as a dependency in your bundle’s pom file.

Drop the built bundle to {WSO2-CC}/repository/components/dropins/. Define the IaasProvider you are going to add and your implementation class in the Cloud Controller's cloud-controller.xml.
Now, you can start using the newly added IaaS in your Cartridge.

Example:

      <iaasProvider type="vcloud" name="vcloud specific details">
              <className>org.wso2.carbon.stratos.iaas.VcloudIaas</className>
        <provider>vcloud</provider>
        <identity svns:secretAlias="cloud.controller.vcloud.identity"/>
        <credential svns:secretAlias="cloud.controller.vcloud.credential"/>
        <scaleUpOrder>1</scaleUpOrder>
        <scaleDownOrder>2</scaleDownOrder>
        <property name="securityGroups" value="default"/>
              <property name="instanceType" value="m1.large"/>
              <property name="keyPair" value="abc-key"/>
        <imageId>us-east-1/ami-abcdef123</imageId>
    </iaasProvider>
