Why Database Gateway
Database Gateway is a database connection service that is secure and cost-effective. It allows you to connect an on-premises database or a database that is hosted on a third-party cloud to Alibaba Cloud in a secure manner at a low cost. Database Gateway provides the following benefits:
Security and reliability: Database Gateway does not expose the IP addresses of databases to ensure the security and stability of your data assets. When an on-premises gateway is started, Database Gateway generates a temporary token and sends the token to the server for verification over an encrypted link. This way, only the current user can use the gateway. The token expires within 15 minutes and can be verified only once.
Ease of use: Database Gateway allows you to connect an on-premises database to Alibaba Cloud without configuring complex networks and routings.
Cost-effectiveness: Database Gateway provides free connection from databases to Alibaba Cloud. You do not need to purchase an Elastic Compute Service (ECS) instance, a virtual private cloud (VPC), or an Express Connect circuit. You can run the proxy gateway on a machine that has available memory. In terms of data transmission, Database Gateway compresses data before it transmits data over the Internet. This reduces network costs.
Ecosystem integration: You can integrate Database Gateway with other database services to enable an ecosystem across cloud services and between on-premises and cloud databases that provides diverse capabilities, such as database migration, disaster recovery, cross-database joining, data analysis, and data security. This ensures the consistency of cloud databases.
