Which service facilitates the integration of various databases on Alibaba Cloud?

The service that facilitates the integration of various databases on Alibaba Cloud is Alibaba Cloud Database Gateway. This service provides a unified gateway that enables applications to access multiple databases seamlessly. It simplifies communication between different database systems, allowing for better data management and integration without requiring significant changes to the application architecture.

The Database Gateway supports various protocols and formats, making it easier to connect and interact with diverse database platforms. This capability is crucial for organizations that operate with hybrid cloud environments or need to consolidate data from multiple sources.

In contrast, the other options, while valuable, do not serve the primary purpose of integrating databases. The Data Synchronization Service is designed for synchronizing data between different database systems but does not provide a unified gateway for integration. The Table Store is a NoSQL database service, which focuses on storing and retrieving data rather than facilitating integration. The Security Center is aimed at security management and doesn’t address database integration needs. Thus, the Database Gateway stands out as the right choice for facilitating integration across various databases on Alibaba Cloud.
