Apply for or release a public endpoint

An AnalyticDB for MySQL cluster supports two types of connection addresses: a VPC address and a public endpoint. If you need to connect to the cluster over the Internet, you must first apply for a public endpoint.

Internet and VPC

Network type	Description
Virtual Private Cloud (VPC)	A VPC is an isolated network environment. We recommend using a VPC for its enhanced security. When you create a cluster, you must specify a VPC for it. You can customize route tables, CIDR blocks, and gateways in a VPC. You can connect your on-premises data center to an Alibaba Cloud VPC by using Express Connect or a VPN to create a hybrid cloud environment and migrate applications to the cloud.
Internet	You need to manually apply for a public endpoint. You can also release it when no longer needed. Use cases for a public endpoint: You need to connect from outside Alibaba Cloud to an AnalyticDB for MySQL cluster. You need to connect to an AnalyticDB for MySQL cluster that is in a different region or uses a different network type.

Log on to the AnalyticDB for MySQL console. In the upper-left corner of the console, select a region. In the left-side navigation pane, click Clusters. Find the cluster that you want to manage and click the cluster ID.
On the Cluster Information page, find the Network Information card, click Apply for Endpoint, and then click OK.

Note
After a public endpoint is generated, if you need to use the public endpoint to access an AnalyticDB for MySQL cluster, you must also add the IP address of the device that you use to access the AnalyticDB for MySQL cluster to an allowlist.
To release the public endpoint, click Release Endpoint and then click OK.
