Hi Lahiru and Devs,
Please find the service methods to talk to jclouds as below. Also, Please
provide your suggestions to make the interface more flexible. Let me
explain, why we have to change the interface?
With the new architecture, autoscaler can take more robust decision from
the stats, its collects from the Event Processing Engine. In the case of
scale down or scale up, it can start/terminate instances within a cloud,
within a region, within a zone, within a network and within a host. If any
of them is not specified in the Locationscope, the cloud controller will
take the decision with the default location. Also, autoscaler can terminate
the unhealthy instances by providing the instance ID.
/**
* Calling this method will result in an instance startup, which is
belong
* to the provided Cluster ID. Also note that the instance that is
starting up
* belongs to the group whose name is derived from its Cluster ID,
replacing <i>.</i>
* by a hyphen (<i>-</i>).
*
* @param clusterId
* cluster ID of the instance to be started up.
* @param locationScope
* It contains the region, zone, network and host of a IaaS
where
* an instance need to be started.
* @return public IP which is associated with the newly started
instance.
*/
public String startInstance(String clusterId, LocationScope
locationScope);
/**
* Calling this method will result in termination of an instance which
is belong
* to the provided cluster Id and the location scope..
*
* @param clusterId
* cluster ID of the instance to be terminated.
* @param locationScope
* It contains the region, zone, network and host of a IaaS
where
* an instance need to be terminated..
* @return whether an instance terminated successfully or not.
*/
public boolean terminateInstance(String clusterId, LocationScope
locationScope);
/**
* Calling this method will result in termination of an instance which
is belong
* to the provided instance Id.
*
* @param instanceId
* instance Id of the instance to be terminated.
* @return whether an instance terminated successfully or not.
*/
public boolean terminateInstance(String instanceId);
/**
* Calling this method will result in termination of all instances
belong
* to the provided cluster ID.
*
* @param clusterId
* cluster ID of the instance to be terminated.
* @return whether an instance terminated successfully or not.
*/
public boolean terminateAllInstances(String clusterId);
/**
* Calling this method will result in termination of the lastly spawned
instance which is
* belong to the provided clusterID.
*
* @param clusterId
* service domain of the instance to be terminated.
* @return whether the termination is successful or not.
*/
public boolean terminateLastlySpawnedInstance(String clusterId);
The LocationScope can be found as below:
public class LocationScope {
private String zone;
private String network;
private String host;
private String region;
private String cloud;
............
}
Thanks,
Reka
