- Instance: A database service process that takes up physical memory independently. You can set different memory size, disk space, and database type, where the memory size determines the performance of the instance. After the instance is created, you can change the configuration or delete the instance at any time.
- Database: A database is a logical unit created in an instance. The name of each database under the same instance must be unique.
- Region and zone: Each region is a separate geographic area. Each region has many isolated locations known as zones. The power supply and network of each zone are independent. For more information, see Alibaba Cloud Global Infrastructure.
