To monitor the progress of a resize operation using the Amazon Redshift console, choose CLUSTERS, then choose the cluster being resized to see the details.
Pausing and resuming clusters
If you have a cluster that only needs to be available at specific times, you can pause the cluster and later resume it. While the cluster is paused, on-demand billing is suspended. Only the cluster's storage incurs charges. For more information about pricing, see the Amazon Redshift pricing page.
Renaming clusters
You can rename a cluster if you want the cluster to use a different name. Because the endpoint to your cluster includes the cluster name (also referred to as the cluster identifier ), the endpoint changes to use the new name after the rename finishes.
Shutting down and deleting clusters
You can shut down your cluster if you want to stop it from running and incurring charges. When you shut it down, you can optionally create a final snapshot. If you create a final snapshot, Amazon Redshift will create a manual snapshot of your cluster before shutting it down.
What is AWS Redshift?from sqlshack.com
AWS Redshift is one of the most popular and heavily used data services for petabyte-scale data warehousing. Considering the high volume of data it can accommodate, the number of nodes in a cluster tend to be high, which translates into higher costs as well, and requires cost-optimization. Typically, in an SDLC environment, there are different AWS Redshift clusters by environments like Dev, Stage, Test and Production, where each environment has at least one or more AWS Redshift clusters housing different volumes of data. Production grade clusters may be required to operate 24 x 7, but development and other lower environment do not require the cluster to operate full time. Ideally, if feasible, one should terminate the cluster and restore it from snapshots once the cluster is required. At times, terminating the cluster and restoring it frequently may be too much of a hassle and may not be worth the effort. In such cases, one may want to pause the cluster which will not eradicate the cost, but at least reduce the costs. In this article, we will learn different options to pause and resume the AWS Redshift cluster and discuss how it will translate into cost savings.
How does Redshift pricing work?from sqlshack.com
The pricing model of AWS Redshift is very straight-forward. Depending on the type of node instance used to build the cluster, on-demand nodes are priced per hour of usage with billing per-second. If the cluster is stopped the compute billing gets stopped and only the storage charge applies. More about the cost savings can be read from here .
What is pause later?from sqlshack.com
The next pause option is Pause later. This option provides the ability to pause the cluster on a schedule. To schedule, provide a schedule name, an optional description, a pause start-date and time. The key thing to note here is that there’s no end time, and it’s just related to pausing of the cluster on the schedule. You may have to resume to cluster manually or on a schedule separately.
What is the third option in a cluster?from sqlshack.com
The third option is to Pause and resume on schedule as shown below. This option like the previous option requires providing schedule related details. The difference in this option is that we need to provide an end-time as well. This end-time would signal the start of resuming the cluster. The editor interface provides options to configure the frequency of the schedule at the desired frequency – like on certain days, weekly, monthly etc. The time is in UTC format, so before specifying the time, consider converting it into UTC format.
What happens when you resume a cluster?from sqlshack.com
You would start getting the metrics back on the graphs and may find the compute metrics going high as the cluster is getting operational again.

Once the schedule is created, you would be able to view the pause and resume schedule on the Schedule tab of the cluster properties page.
Why migrate to cloud?from sqlshack.com
One of the motivations for migrating from on-premises to cloud-hosted models like Infrastructure as a Service, Platform as a Service or Software as a Service is cost savings due to reduced infrastructure management and related administrative tasks or resources required to keep the solution functional. One of the factors that enables saving costs on the cloud is the pricing model. Generally, for most of the cloud-based services, there is no upfront cost or long-term commitment and service is charged as per the use. Considering this in the database world, the charges vary on factors like instance-size, features enabled, multi availability zone deployment, storage volumes etc. One factor that is common across any database is the time or duration for which the database was used. Once the resources or instance is terminated and/or stopped, then the charges no longer apply. This pricing model makes it necessary to scale down, stop or terminate (whichever applicable) the resources and instances once they are not in use. This would require the ability to perform the action ad-hoc as well as in a scheduled manner.
