You can create instances that run different database engines in ApsaraDB for MyBase dedicated clusters. A MyBase for PostgreSQL instance allows you to have more permissions than those you can have on an ApsaraDB RDS for PostgreSQL instance. This topic provides an overview of MyBase for PostgreSQL and introduces related concepts.
MyBase for PostgreSQL
- ApsaraDB for MyBase dedicated clusters: An ApsaraDB for MyBase dedicated cluster consists of multiple hosts, such as ECS instances of the ecs.i2.xlarge instance type and ECS Bare Metal instances. You can run instances on these hosts. For more information, see What is ApsaraDB for MyBase?
- You can upload encrypted data from the user end to your MyBase for PostgreSQL instance. The database instance protects your data against internal and external security threats and allows only authorized users to access the data. For more information, see Overview.
- Read-only RDS instances: If the primary RDS instance is overwhelmed by a large number of read requests, your workloads may be interrupted. In this situation, you can create one or more read-only RDS instances to offload read requests from the primary RDS instance. For more information, see Create a read-only ApsaraDB RDS for PostgreSQL instance. By creating one or more read-only RDS instances, you can scale up the read capability of your database system and increase the throughput of your application.
Benefits of the engine of MyBase for PostgreSQL
- Compatible with NoSQL: The engine of MyBase for PostgreSQL is compatible with SQL 2011 and supports a variety of data types. You can execute SQL statements to manage JSON and XML data.
- Support for multiple versions: PostgreSQL 10, 11, 12, and 13 are supported.
- Support for a spatial or spatio-temporal engine: The spatio-temporal engine Ganos that is developed by Alibaba Cloud provides capabilities for multi-model processing and accelerates GPU computing. The engine of MyBase for PostgreSQL is compatible with the geographic information engine PostGIS.
