Creating an Environment
You can create application components in different environments to isolate them.
![](https://support.huaweicloud.com/intl/en-us/usermanual-cae/public_sys-resources/note_3.0-en-us.png)
By default, only one environment can be created under an account. Submit a service ticket to increase the quota.
Prerequisites
A CAE runs on a VPC. Before creating an environment, ensure that VPCs and subnets are available.
For details, see Creating a VPC.
If the engine is created using an account with the minimum permission for creating engines, for example, cae:environment:create in the fine-grained permission dependencies of CAE, the default VPC security group cae-default-sg needs to be preset by the primary account and the rules listed in Table 1 need to be added.

Description
Environment
Enter an environment name.
Enterprise Project

An enterprise project facilitates project-level management and grouping of cloud resources and users. The default project is default.
It is available after the enterprise project function is enabled.
Virtual Private Cloud
Select the VPC to which the environment resource belongs from the drop-down list.
To create a VPC, click Create VPC. For details, see Creating a VPC.
NOTE:The VPC cannot be modified after the environment is created.
Subnet
Select a subnet from the drop-down list.
If no subnet is available, click Create Subnet to access the network console and create a subnet. For details, see Creating a Subnet for the VPC.
NOTE:Keep at least two available network IP addresses for CAE configuration and optimization.
Security Group
You can select Auto generate or Use existing.
NOTE:This group must allow access from the selected subnet to both the subnet gateway address and the access addresses and ports of middleware such as RDS and CSE instances.
Organization
If you use CAE for the first time, select Create Organization from the drop-down list and enter an organization name.
