Ensure that all Redshift clusters provisioned within your AWS account are using the latest generation of nodes (instances) in order to get higher performance with lower costs. If you are currently using Amazon Redshift nodes from the previous generation (i.e. ds1.xlarge or ds1.8xlarge), Cloud Conformity encourages you to upgrade these nodes to their latest generation equivalents (ds2.xlarge or ds2.8xlarge).
Using the latest generation of AWS Redshift nodes instead of the previous generation nodes will upgrade your clusters for higher hardware performance (more computing capacity and faster CPUs, more RAM memory and higher disk throughput using solid-state disks) at the same costs.
The previous generation of Amazon Redshift node types in use are ds1.xlarge and ds1.8xlarge. To determine if your Redshift clusters are using node types from the previous generation, perform the following:
The following table will help you choose the equivalent current generation node type required for the upgrade process:
