Changing ECS Names Scenarios After an ECS is created, you can change its name as needed. Multiple ECS names can be changed in a batch. After the change is complete, the ECS names will be identical. Changing the Name of a Single ECS Log in to the management console. Click in the upper
Managing ECS Groups Scenarios An ECS group logically groups ECSs. ECSs in an ECS group comply with the same policy. Currently, only the anti-affinity policy is supported. This policy enables ECSs in the same ECS group to run on different hosts for improved reliability, high availability
Managing ECS Status You can start, stop, restart, unsubscribe, or delete the ECS. To prevent a sudden load increase, you are advised to start or stop a small number of ECSs at a time. If an ECS remains in the Restarting or Stopping state for a long time, you can forcibly restart or
Migrating an ECS to a DeH Scenarios ECSs can be migrated: Between Dedicated Hosts (DeHs) From a DeH to a public resource pool From a public resource pool to a DeH This section describes how to migrate an ECS from a public resource pool to a DeH. Before migrating an ECS, ensure that
Adding a Disk to an ECS Scenarios If the storage space on your ECS is insufficient, you can purchase EVS disks to add more storage space. The disks attached to an ECS include one system disk and one or more data disks. The system disk is automatically created and attached when the
Basic ECS Metrics Description This section describes basic monitoring metrics reported by ECS to Cloud Eye. You can use Cloud Eye to view these metrics and alarms generated for ECSs. Namespace SYS.ECS Basic ECS Metrics Basic ECS metrics vary depending on ECS OSs and types. For details
Monitored ECS Events Scenarios Event monitoring provides data collection, query, and alarm reporting for events. You can create alarm rules to get notified when specific events happen. This section describes the ECS events monitored by Cloud Eye. Namespace SYS.ECS Monitored Events
Backing Up an ECS Scenarios Cloud Backup and Recovery (CBR) enhances data integrity and service continuity. For example, if an ECS or EVS disk is faulty or a misoperation causes data loss, you can use data backups to quickly restore data. This section describes how to back up ECSs
Installing UniAgent on an ECS Scenarios Self-service O&M operations on ECSs such as hostname change and online password reset depend on UniAgent provided by Application Operations Management (AOM). If UniAgent is not installed or the installation failed, you need to log in to the
Changing ECS Hostnames Scenarios You can change the static hostnames of Linux ECSs after they are created. The static hostname of a Linux ECS is user defined and injected using Cloud-Init during the ECS creation. After an ECS is created, you can change its name and hostname on the
Viewing ECS Metrics Scenarios The cloud platform provides Cloud Eye, which monitors the statuses of your ECSs. You can obtain the monitoring metrics of each ECS on the management console. There is a short time delay between transmission and display of monitoring data. The status of
Attaching a Disk to an ECS Scenarios If the existing disks of an ECS fail to meet service requirements, for example, due to insufficient disk space or poor disk performance, you can attach more available EVS disks to the ECS, or purchase more disks (choosing Storage > Elastic Volume
ECS Application Scenarios Internet No special requirements for CPUs, memory, disk space, or bandwidth High security and reliability standards Deploying an application on one or only a few ECSs to minimize upfront investment and maintenance costs, such as website development and testing
