Hello Vatsal,
One note from that document to consider: "One of the key responsibilities for a customer is to determine whether or not they are a Covered Entity (or a Business Associate of a Covered Entity) and, if so, whether they require a Business Associate Agreement with Google for the purposes of their interactions. While Google provides a secure and compliant infrastructure (as described above) for the storage and processing of PHI, the customer is responsible for ensuring that the environment and applications that they build on top of Google Cloud are properly configured and secured according to HIPAA requirements. This is often referred to as the shared security model in the cloud."
If you do need a BAA in order to achieve compliance, you'll want to look at the list of covered products later in that document.
