Notes and Constraints

Account and Quota

You can only create a certain number of instances with certain total memory by default. Quotas are different by user and by region. Refer to the quota displayed on the console. For more information about quotas, see Quotas. To increase quotas, submit a service ticket.

Network

VPCs are used to manage the network security of cloud services.

  • The client must be deployed on an ECS that belongs to the same VPC as the DCS instance.
  • For a DCS Redis 3.0/6.0 professional/Memcached instance, select the same security group for the DCS instance and the ECS where your client is deployed. If the DCS instance and ECS belong to different security groups, add inbound and outbound rules for the security groups. For more information on how to add the rules, see the "How Do I Configure a Security Group" FAQ.
  • For a DCS Redis 4.0/5.0/6.0 basic edition instance, add the IP address of the ECS where your client is deployed to the whitelist of the instance. For details, see Managing IP Address Whitelist.

Scaling

You can scale up an instance only within the remaining quota scope. If your quota is insufficient, submit a service ticket to increase the quota.
