Amazon Redshift Cluster - Pause and Resume - Series 7

In this series, let us see how the Amazon Redshift clusters function when a 'Pause' is applied, the below listed actions will happen

1. A snapshot is created on every Pause applied or scheduled-applied
2. Running queries are terminated 

Ideally, we cannot stop the 'Pause' or 'Resume' operations after it is applied or initiated. 

How all these 'Pause and Resume' can be applied:

1. From Amazon Redshift console
2. AWS CLI
3. Amazon Redshift API calls

 Which Clusters cannot be 'Paused & Resumed':

1. Classic EC2 clusters
2. Clusters that are modification state
3. HSM Clusters
4. Clusters for those 'Automated Snapshots' are disabled; this is because, 'Pause' operation creates a snapshot and this cannot be completed with 'Automated Snapshots' in disabled state
