This topic provides an overview about ApsaraDB MyBase.
ApsaraDB MyBase is a dedicated database solution developed by Alibaba Cloud to provide customized and optimized database services for enterprise users. An ApsaraDB MyBase dedicated cluster consists of multiple hosts. These hosts can be Elastic Compute Service (ECS) instances of the i2 instance family and ECS Bare Metal instances. Compared with fully managed database solutions, an ApsaraDB MyBase dedicated cluster can meet more business requirements.
ApsaraDB MyBase supports the MySQL, SQL Server, and PostgreSQL database engines. ApsaraDB MyBase allows you to use dedicated cloud resources and supports resource overcommitment. ApsaraDB MyBase also allows you to perform O&M operations on hosts and grant accounts database and OS permissions. ApsaraDB MyBase enables flexible resource scheduling and meets the requirements for database regulatory compliance and security.
ApsaraDB MyBase allows you to manage multiple database instances within a dedicated cluster. You can create multiple dedicated clusters in a region. Each dedicated cluster can contain multiple hosts and each host can support multiple instances.
ApsaraDB MyBase provides the following features for dedicated clusters:
- Resource scheduling: You can configure an overcommit ratio for each type of resources to utilize the resources in the most efficient manner. Resources are divided into multiple types, such as CPU, memory, storage, IOPS, and network traffic.
- Host management: A host serves as a container for ApsaraDB MyBase resources. You can manage hosts. For example, you can add, replace, and connect to hosts. You can also specify whether instances can be allocated to a host.
- Instance management: You can manage the primary instance, secondary instances, read-only instances, and instances that are used to store log entries.
