Figure 1 Relationships between ECS and other services

ECS-related Services

**Table 1** ECS-related services
Service	Function	Related Operation
Auto Scaling (AS)	Automatically adjusts ECS resources to keep up with changes in demand based on the configured AS policies. This improves resource utilization and reduces costs.	Using an Existing ECS to Create an AS Configuration
Elastic Load Balance (ELB)	Automatically distributes traffic to multiple ECSs. This improves fault tolerance.	Adding Backend Servers
Elastic Volume Service (EVS)	Allows you to attach EVS disks to an ECS and expand their capacity.	Attaching a Non-Shared Disk Attaching a Shared Disk
Virtual Private Cloud (VPC)	Allows you to create your own dedicated network on the cloud by customizing security groups, VPNs, IP address ranges, and bandwidths. This simplifies network management. You can also customize the ECS access rules within a security group and between security groups to improve ECS security.	Assigning an EIP and Binding It to an ECS Adding a Security Group Rule
Image Management Service (IMS)	Allows you to create ECSs using images. This improves the efficiency of ECS creation. You can also use an existing ECS to create a private image and export the data of the ECS system disk or data disks.	Creating a Data Disk Image from an ECS Creating a Full-ECS Image from an ECS
Dedicated Computing Cluster (DCC)	To physically isolate your ECS, apply for a DCC before creating the ECS. After you obtain the DCC and set a region for it, your ECS is automatically allocated to the DCC.	Enabling a DeC
Cloud Eye	Allows you to check the status of monitored ECS resources. This can be done without requiring additional plug-ins.	Basic ECS Metrics OS Monitoring Metrics Supported by ECSs with the Agent Installed Process Monitoring Metrics Supported by ECSs with the Agent Installed
Data Encryption Workshop (DEW)	The encryption feature relies on DEW. You can use an encrypted image or EVS disks when creating an ECS. In such a case, you need to use the key provided by DEW to improve data security.	EVS Encryption Encrypting Images
Cloud Trace Service (CTS)	Records ECS-related operations for later query, auditing, and backtracking.	Supported CTS Operations
Cloud Backup and Recovery (CBR)	Backs up EVS disks and ECSs for fault recovery.	Creating a Server Backup Vault
Tag Management Service (TMS)	Identifies ECSs to help classification and search.	Adding Tags Searching for Resources by Tag
