Connecting to a Backend Data Source

Overview

Before creating a data API, connect to a data source to read data from. Access configuration varies depending on the data source type.

Prerequisites

Before accessing a data source, ensure that the ROMA Connect instance can connect to the network where your data source resides.
- Same VPC: The instance can directly access the data source.
- Two VPCs in the same region: Connect the instance and the data source using a peering connection. For details, see VPC Peering Connection.
- Two VPCs in two regions: Connect the instance and the data source using a peering connection.
- Communication over the public network: Ensure that the ROMA Connect instance has been bound with an EIP.
To enable cross-VPC private access, configure the routes between the instance and the subnet where the data source resides.
Users who connect to a data source must have permission to create a session for connecting to the database.
For details about the data source versions supported by ROMA Connect, see Supported Data and Protocols.
