You can create a MongoDB instance on the MongoDB console. For more information about instance billing, see Billing items and pricing. This document introduces how to create an instance on the MongoDB console.

Prerequisites

• You have a registered Alibaba Cloud account.

• To create a Pay-As-You-Go instance, confirm your account balance is equal to or higher than 100 RMB.

Procedure

1. Log on to the MongoDB console.

2. Click Create Instance on the Replica Set Instances page to go to the instance creation page.

3. Select Subscription or Pay-As-You-Go. For more information about instance billing, see Billing items and pricing.

   Parameter configuration area	Parameter	Description	Remark
   Basic configuration	Region Zone Database version	Select the instance region, zone, and database version. Currently, MongoDB 3.2 is supported.	Products in different regions cannot intercommunicate through intranet, and you cannot change the instance region after purchasing the instance. Therefore, be aware when selecting the region.
   Network type	Classic network VPC	MongoDB supports classic networks and virtual private clouds (VPCs). The VPC needs to be created beforehand. Alternatively, you can change the network type after creating an instance. For more information, see Switch from classic network to VPC. Classic network: Cloud services on the classic network are not isolated, and unauthorized access can be blocked only by the security group or whitelist policy of the cloud services. VPC: VPCs help you build an isolated network environment on Alibaba Cloud. You can customize the route table, IP address range, and gateway on the VPC. You can also combine your machine room and cloud resources in the Alibaba Cloud VPC into a virtual machine room through a leased line or VPN. This allows you to smoothly migrate applications to the cloud.	N/A
