Hi Anmol,
Here SAP HANA Cloud Platform it states that;
The services on SAP HANA Cloud Platform can be consumed by applications that are deployed on SAP HANA Cloud Platform but not from external applications. There are cases, however, where applications want to access content in the cloud but cannot be deployed in the cloud.
You can simply create a proxy class by extending AbstractCmisProxyServlet and consume the service via this proxy.But I don't know any API's to get the status of the service.
