Durante la migración de la base de datos, la base de datos de Cloud SQL de destino debe conectarse
a la base de datos de origen. Database Migration Service proporciona varias formas de configurar esta conectividad. El método de conectividad que elijas depende del tipo de base de datos de origen y de si reside de forma local, en Google Cloudo en otro proveedor de servicios en la nube.
Existen tres tipos de métodos de conectividad que puedes configurar:
Túnel SSH inverso con una VM alojada en la nube: Elige este método si deseas usar una conectividad segura y no tienes una red de nube privada virtual (VPC) desde Google Cloud la que puedas acceder a la base de datos de origen.
Intercambio de tráfico entre VPC: Elige este método si deseas usar conectividad privada y cuando tengas una red de VPC en Google Cloud desde la que puedas acceder a la base de datos de origen. Usa el intercambio de tráfico entre VPC si tienes una conexión de VPN o Cloud Interconnect configurada en Google Cloud.

Database Migration Service provides several ways to configure\nthis connectivity. The connectivity method you choose depends on the type of\nsource database, and whether it resides on-premises, in Google Cloud, or in another\ncloud provider.\n\nYou can configure the following connectivity methods:\n\n- [IP allowlists](/database-migration/docs/postgres/configure-connectivity-ip-allowlists): Choose this method if you want to use public connectivity.\n- [Reverse SSH tunnel using a cloud-hosted VM](/database-migration/docs/postgres/configure-connectivity-reverse-ssh-tunnel): Choose this method if you want to use secure connectivity, and when you don't have a virtual private cloud (VPC) network in Google Cloud from which you can reach the source database.\n- Private connectivity: Choose this method if you want the destination database to connect to the private IP of your source. There are two types of private connectivity available:\n - [Private Service Connect interfaces](/database-migration/docs/postgres/configure-connectivity-vpc-peering#psc-interfaces): This connectivity method lets your destination database initiate connections to the private IP of your source database without consuming peering quota. Instead, Private Service Connect interfaces use network attachments you create in your VPC.\n - [VPC peering](/database-migration/docs/postgres/configure-connectivity-vpc-peering#vpc-peering): This method requires that you have a VPC network in Google Cloud from which you can reach the source database. Use VPC peering if you have a [VPN](/database-migration/docs/postgres/configure-connectivity-vpns) or Cloud Interconnect connection set up in Google Cloud.\n\nWhat's next\n-----------\n\n- Learn more about [private services access](/vpc/docs/private-services-access).\n- Learn more about [Private Service Connect interfaces](/vpc/docs/about-private-service-connect-interfaces).\n- Learn more about [using VPC peering](/vpc/docs/using-vpc-peering)."]]
