This page summarizes the AlloyDB Language Connectors and how to use them
with your clusters.
AlloyDB Language Connectors are libraries that provide automated mTLS
with TLS 1.3 and Identity and Access Management (IAM) authorization
when connecting to an AlloyDB for PostgreSQL instance.
AlloyDB Language Connectors create authorized connections to the
proxy-side server on behalf of a user's application and pass that connection to
the application's database driver. They don't provide a network path to an
AlloyDB instance if one is not already present.
AlloyDB supports the following AlloyDB Language Connectors:
You can use AlloyDB Language Connectors to connect to your
AlloyDB cluster.
Benefits of AlloyDB Language Connectors
AlloyDB Language Connectors provide the following
benefits when connecting to a AlloyDB cluster:
Access control: Uses IAM (IAM)
permissions to control who or what can connect to your AlloyDB
instances.
Convenience: Uses automatic mTLS to provides extended mutual
security. Removes requirement to manage SSL certificates, configure firewall rules, or enable authorized networks.
How AlloyDB Language Connectors work
AlloyDB Language Connectors use a client-side component to connect to a proxy server
on the AlloyDB cluster. The connector creates a temporary certificate
that authorizes the holder to connect to the server-side proxy. The server-side
proxy limits access to the AlloyDB database by requiring a valid TLS
certificate in order to connect.
You can also to connect to a AlloyDB cluster
using the AlloyDB Proxy. For more information about
connecting to a AlloyDB cluster,
see the Connection overview.
