Basic Concepts

Namespace

A namespace is a collection of all resources (traffic input, multi-active areas, data synchronization records, and monitoring information) for a MAS instance. You can create a namespace for each system (such as OA and payment systems) to isolate resources for security and efficiency.

Instance

An instance is the minimum resource unit provided by MAS.

A MAS instance is an independent resource space where all operations are performed. Resources of different instances are isolated from each other. You can use one or more MAS instances as required.

AZ

An AZ is a physical region where resources use independent power supplies and networks. AZs are physically isolated but connected through an internal network.

For maximum availability, deploy the MAS instance in multiple AZs. For minimum latency, deploy the MAS instance in the same AZ. The selected AZs must match your deployment architecture.

Enterprise Project

An enterprise project makes it easy to manage projects and group cloud resources and users.

Application

An application is a service system with functions and consists of one or more application components.

Monitor

A monitor detects your database status, and automatically triggers traffic switching when the database is abnormal.

MAS provides the MySQL, Oracle, PostgreSQL, Redis, MongoDB, Elasticsearch, and API monitors, and displays the real-time monitoring status.

Workflow

MAS orchestrates and executes workflows to provide a complete process for cross-region DR active-active switchover.
