This topic describes how to create a cluster in the PolarDB console.
Prerequisites
An Alibaba Cloud account is registered and is used to log on to the PolarDB console. For more information, see .
Background information
A cluster consists of one primary node and a maximum of 15 read-only nodes. To ensure high availability, at least one read-only node is required to implement the active-active architecture. A node is a virtual database server. You can create and manage multiple databases on a node.
supports only Virtual Private Cloud (VPC). Each VPC is an isolated network on Alibaba Cloud and is more secure than the classic network.
To fully leverage the performance of PolarDB, your PolarDB cluster needs to be deployed in the same internal network with other Alibaba Cloud services. To make full use of the capabilities provided by PolarDB, we recommend that you deploy PolarDB clusters and Elastic Compute Service (ECS) instances in the same VPC. If your ECS instance is deployed in a classic network, you must migrate the instance to a VPC.
