Connecting to Data Sources
Overview
Before creating a data API, you need to connect to a data source to ensure that data can be read from the source. The data source connection configuration varies depending on data source types.
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. For details, see Network Communications Among VPCs Across Regions.
- 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.
