Identifying Requirements

Before creating a DCS instance, identify your requirements and complete the following preparations:

1. Decide on the required cache engine version.

   Different Redis versions have different features. For details, see Comparing Redis Versions.

2. Decide on the required instance type.

   DCS provides single-node, master/standby, Proxy Cluster, and Redis Cluster types of instances. Each type has its own architecture. For details about the instance architectures, see DCS Instance Types.

3. Decide on the required instance specification.

   Each specification specifies the maximum available memory, number of connections, and bandwidth. For details, see DCS Instance Specifications.

4. Decide whether backup policies are required.

   Currently, backup restoration policies can be configured for instances other than single-node ones. For details about backup and restoration, see Overview.
