# Managing ECS Groups

#### Scenarios

An ECS group allows you to create ECSs on different physical servers, thereby improving service reliability. This function does not apply to existing ECSs. You cannot add existing ECSs to an ECS group.

#### Notes

An existing ECS cannot be added to an ECS group.

#### Procedure

1. Log in to the management console.
2. Click in the upper left corner and select your region and project.
3. Under Computing, click Elastic Cloud Server.
4. In the navigation pane on the left, choose ECS Group.
5. On the ECS Group page, click Create ECS Group.
6. Enter the name of the target ECS group.

   The Anti-affinity policy is used by default.

7. Click OK.

#### Follow-up Procedure

Add an ECS to an ECS group only when creating the ECS.

To do so, expand Advanced Options and select the target ECS group.
