step by step AWS Redshift database cluster encryption :
This process has 2 steps and it needs down time from the application and during that time Redshift cluster will not be available for ETL & its in Read ONLY mode.Encryption process will be time consuming based on the size of data on it.AWS will try to recreate the cluster during encryption process and move to other cluster.
1)create encryption key using AWS KMS (Key Management System)
2)Apply KMS Key to Redshift cluster
