What is Database Gateway?
Database Gateway (DG) is a database connection service that enables secure, low-cost remote access to databases in private networks. With DG, you can connect databases from third-party clouds or on-premises data centers to Alibaba Cloud. You can also integrate DG with other Alibaba Cloud products, such as Data Transmission Service (DTS), Data Disaster Recovery, and Data Management (DMS).

Why choose Database Gateway
Database Gateway offers a secure, reliable, and low-cost way to connect databases from third-party clouds or on-premises data centers to Alibaba Cloud. It provides the following benefits:
Security and reliability: Database Gateway does not expose the public IP addresses of your databases. This ensures the security and stability of your data assets. When an on-premises gateway starts, you must generate a temporary token in the console. The gateway sends this token to the server-side over an encrypted link for validation. This process ensures that only the intended user can use the gateway. The token expires in 15 minutes and can be used for validation only once.
Ease of use: You can connect an on-premises database to Alibaba Cloud in a few simple steps without requiring complex network or routing configurations.
Low cost: Database Gateway is a free database connection service. You do not need to purchase an Elastic Compute Service (ECS) instance, a Virtual Private Cloud (VPC) network, or an Express Connect circuit. The on-premises gateway agent can run on any machine with available memory. Data is compressed during transmission over the public network, which further reduces your network costs.
Full ecosystem service: Database Gateway lets you connect to a growing number of database products. This enables a full ecosystem of services that span across clouds and between cloud and on-premises environments. These services include capabilities such as data migration, disaster recovery, cross-database joins, data analytics, and data security. This ensures that you receive a consistent experience with cloud database products.
