You can use the Data Integration Hosted Agent (Hosted Agent) as a runtime environment for a Google BigQuery connection if you have the Cloud Runtime license.
Data Integration Secure Agents are installed locally. As an alternative to installing a Secure Agent, you can use a Hosted Agent. Hosted Agents are hosted at Data Integration hosting facility. The Data Integration hosting facility manages the Hosted Agent runtime environment and the agents that run in it. You cannot add, delete, or configure a Hosted Agent runtime environment. Because you do not install a Hosted Agent, you do not have access to files normally stored in the Secure Agent directory, such as configuration, success, and reject files.
