Scenario
Managing Cloud Server Groups is a way to centrally manage multiple VM instances hosted in a cloud computing environment. Here are some scenarios:
1. Resource organization and classification
· Group by project or department: Organize VM instances for different projects or departments in different server groups for easy management and resource allocation.
2. Permission and security management
· Access control and permission assignment: You can control the permissions of users or teams based on server groups to restrict their operating permissions on VMS in specific server group.
· Security policy application: Apply unified security policies and protective measures to VMs within a specific group to ensure security.
3. Performance optimization and monitoring
· Resource allocation and load balancing: Resource allocate and load balance virtual machines within a server group to optimize performance and resource utilization.
· Monitoring and alarm: Centrally manage server groups to facilitate VM monitoring and exception alarm.
4. Backup and disaster recovery
· Unified backup policy: Setting consistent backup policies for VMs within a specific server group to simplify backup and recovery.
· Disaster recovery management: A disaster recovery plan can be developed for the server group to ensure high availability and disaster recovery for VMs within the server group.
5. Automated deployment and updates
· Batch deployment and updates: Unified and automated management of software updates and system deployment of VMs within the server group to improve efficiency and consistency.
6. Resource adjustment and optimization
· Elastic scaling up/down: Flexibly adjust the resource scale according to the needs of the VMs in the server group to achieve elastic scaling up/down.
7. Cost management
· Resource cost analysis: By managing server groups, it is convenient to track and analyze resource costs, optimize resource utilization, and reduce costs.
The management of cloud server groups can help administrators manage large-scale VM instances more efficiently, improve resource utilization, reduce management costs, and better meet business needs.
Restriction and Limitations
· Limit on the number of instances in a cloud server group: The maximum number of instances that a cloud server group supports is 16.
· Maximum number of cloud server groups: The maximum number of cloud server groups created can be adjusted, with a default of 256. If you need to expand the quota, please contact customer service to apply.
Create server group
If you do not have any server group, you need to create a new one and configure the server group policy.
1. Log in to the console.
2. Click at the top of Control Center and select Region.
3. Click Product and Service List in the left navigation bar and select Computing > Elastic Cloud Server.
4. Select Cloud Server Group in the left navigation bar.
5. Click the Create Cloud Server Group button.
6. Determine server group name: Enter a server group name that meets the following rules.
· It can only Contain Chinese and English letters, numbers, underlines(_), dashes(-) and dots(.).
· The length is between 1 and 64 characters.
1. Select server group policy: Select the appropriate server group policy based on your needs. The available policies are:
· Mandatory affinity policy: Strictly enforce the creation of cloud servers on the same host.
· Affinity policy: Try to create the cloud servers on the same host, but which cannot ensure strict enforcement.
· Mandatory anti-affinity policy: Create the cloud servers dispersedly on different hosts.
· Anti-affinity policy: Try to create the cloud servers dispersedly on different hosts, but cannot ensure strict enforcement.
1. Click OK to complete the creation of server group and policy configuration.
Create a new cloud server and add it to the server group
1. Log in to the console.
2. Click at the top of Control Center and select Region.
3. Click Product and Service List in the left navigation bar and select Computing > Elastic Cloud Server.
4. Click Create Cloud Server.
5. After network configuration, go to Advanced Configuration.
6. Under the Create Password configuration, configure the cloud server group and click Select Cloud Server Group.
7. Select the target cloud server group in the window.
Note
Each cloud server group can add up to 16 cloud servers by default. You can view the number of cloud servers already in the cloud server group by clicking View Cloud Server Group.
1. Click OK to add the cloud server to the selected server group.
Add the existing cloud servers to the server group
1. Log in to the console.
2. Click at the top of Control Center and select Region.
3. Click Product and Service List in the left navigation bar and select Computing > Elastic Cloud Server.

5. Click the name of the target cloud server group to enter the details page of the cloud server group.
6. Click Add Cloud Server and select as many cloud servers as needed to join the cloud server group.
7. Click OK to add the selected cloud servers to the target server group.
Remove cloud server from the cloud server group
1. Log in to the console.
2. Click at the top of Control Center and select Region.
3. Click Product and Service List in the left navigation bar and select Computing > Elastic Cloud Server.
4. Select Cloud Server Group in the left navigation bar.
5. Click the name of the target cloud server group to enter the details page of the cloud server group
6. Select the cloud server to be removed, and click Remove Cloud Server under the Action bar of the cloud server.
7. Click OK to remove the cloud server from the cloud server group.
