ECS Overview An ECS is a basic computing unit that consists of vCPUs, memory, OS, and EVS disks. After creating an ECS, you can use it like using your local computer or physical server, ensuring secure, reliable, and efficient computing. ECSs support self-service creation, modification
ECS Lifecycle The ECS lifecycle refers to the entire journey an ECS goes through, from creation to deletion (or release). Table 1 ECS statuses Status Status Attribute Description Creating Intermediate The ECS is being created. Starting Intermediate The ECS is being started. Running
ECS Advantages ECS supports automated scaling of compute resources based on traffic changes and predefined scaling policies. You can customize ECS specifications including vCPUs, memory, and bandwidth to let your applications run in a flexible, efficient environment. Reliability A

Preparing an ECS If the client tool runs on Linux, you need to prepare a Linux ECS that is in the VPC as a CloudTable cluster and the Linux ECS serves as a client host. If you use the following client tools to access a cluster, you are advised to use the HBase shell, a Linux ECS.
Preparing an ECS Before using a cluster, you need to use a client to connect to the database. After the client is installed, you can access the cluster via the private network address of the cluster. Preparing an ECS For details about how to purchase an ECS, see Purchasing an ECS.
Preparing an ECS Preparing an ECS For details about how to purchase an ECS, see Purchasing an ECS. To purchase an ECS, the following requirements must be met: The ECS must have the same region, AZ, VPC, and subnet as the CloudTable cluster. For details about how to create a VPC, see
Ranking with DCS Overview Ranking is a function commonly used on web pages and apps. It is implemented by listing key-values in descending order. However, a huge number of concurrent operation and query requests can result in a performance bottleneck, significantly increasing latency
DCS Metrics Introduction This section describes DCS metrics reported to Cloud Eye as well as their namespaces and dimensions. You can use the Cloud Eye console or call APIs to query the DCS metrics and alarms. Cloud Eye supports up to 4 hierarchical dimensions, numbered from 0, with
Auto-renewing an ECS Auto-renewal can prevent ECSs from being automatically deleted if you forget to manually renew them. The auto-renewal rules are as follows: The first auto-renewal date is based on when the ECS expires and the billing cycle. The auto-renewal period of an ECS varies

Creating an ECS Function This API is used to create one or more ECSs. The V1.1 API supports all functions provided by the V1 API. For details, see Creating an ECS (Pay-per-Use). Additionally, the V1.1 API supports the creation of yearly/monthly ECSs. This API is an asynchronous API
Redeploying an ECS Function This API is used to redeploy an ECS. URI POST /v1/{project_id}/cloudservers/{server_id}/actions/redeploy Table 1 describes the parameters in the URI. Table 1 Path parameters Parameter Mandatory Description project_id Yes Specifies the project ID. For details
Creating an ECS Scenarios This section describes how to create an ECS by calling APIs. For details, see Calling APIs. An ECS can be created using a disk or image. This section uses an image as an example to describe how to create an ECS. Constraints The ECS created using this API
ECS Statuses An ECS can be in one of the following statuses specified in ECS APIs: status: specifies an ECS status, which is generated by OS-EXT-STS:vm_state and OS-EXT-STS:task_state. OS-EXT-STS:vm_state: indicates that the ECS is in a stable state after an operation is performed
