Buy an ECS, log in to it, and install the Redis client by referring to redis-cli. Use redis-cli to access the load balancer using its EIP and port number (which is 80). Write a key through ELB. Log in to the DCS console.
Check whether the following resources are sufficient: available ECS space, target instance flavor, and remaining memory (≥ source Redis data).

To access the instance in an Elastic Cloud Server (ECS), select the VPC where the ECS is. The VPC and subnet are fixed once the DCS instance is created. A shared VPC implements network resource sharing, and unified and efficient management and control at low O&M costs.
To upload it to an ECS, see File Upload/Data Transfer. Add the path of the ca.crt file to the command for connecting to the instance. For example, to access an instance on redis-cli, see Connecting to Redis on redis-cli.

Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), and Object Storage Service (OBS), are shared within the same region. AZs in the same region can communicate with each other over an intranet, but AZs in different regions cannot.
You can also create an ECS in the VPC housing the instances and connect the ECS and instances through a floating IP address. Subnets and security groups can be used together to isolate DCS instances and enhance security.

Check whether the redis-benchmark executable file exists. ls Install the tool in the system. make install Method 2: Install the Redis server matching the ECS OS. The following examples use Ubuntu and CentOS.

Only one ECS is required for testing on a single-node or master/standby instance. Configure the same AZ, VPC, subnet, and security group for the ECSs and the instance. Install memtier_benchmark on each ECS. CentOS 8.0 is used as an example.
The ECS must use the same VPC, subnet, and security group as the Redis instance. Procedure Access the target Redis instance using redis-cli.

When creating a node pool, set Node Type to Elastic Cloud Server (VM), Container Engine to Docker, OS to CentOS 7.6, and bind an existing EIP or create one. Procedure Creating a Client Image Download a Redis client. Log in to the CCE cluster node.

To access a DCS Memcached instance, you must use an ECS that is in the same VPC as the DCS instance. In the application development and debugging phase, you can also use an SSH agent to access DCS Memcached instances in the local environment.
