So we have to take care of the Manual snapshots instead of Automated snapshots. Manual snapshots are retained even after you delete your cluster.īecause manual snapshots accrue storage charges, it’s important that you manually delete them if you no longer need them.Īutomated snapshots are automatically deleted within the period of 1(Least) to 35(Max) days(Based on the retention period settings). Amazon Redshift will never automatically delete a manual snapshot. Regardless of whether you enable automated snapshots, you can take a manual snapshot whenever you want. Choose to use Instance store volumes to store the cluster data. Choose to use Spot Instances instead of Reserved Instances.ĭ. Set the retention period of the automated snapshots to 35 days.Ĭ. Which of the following steps can be carried out to minimize the costs being incurred by the cluster?ī. There has been a recent concern on the cost being incurred by the cluster. Since the cluster is going to be run for a long duration of a couple of years, Reserved Instances have been purchased. The IT Operations team have ensured that both automated and manual snapshots are in place. A company has a Redshift Cluster defined in AWS. Any amount of storage exceeding this limit does incur cost. There is no additional charge for backup storage up to 100% of your provisioned storage for an active data warehouse cluster. Enhanced VPC routing does not incur any cost but any Unload operation to a different region will incur a cost.With Enhanced VPC routing or with out it any data transfer to a different region does incur cost.But with Storage, increasing your backup retention period or taking additional snapshots increases the backup storage consumed by your data warehouse. You might incur additional data transfer charges for certain operations, such as UNLOAD to Amazon S3 in a different region or COPY from Amazon EMR or SSH with public IP addresses. For all other data transfers into and out of Amazon Redshift, you will be billed at standard AWS data transfer rates.Data scanned There is no additional charge for using Enhanced VPC Routing. Note: Redshift pricing is based on the following elements.Compute node hours Backup StorageData transfer – There is no data transfer charge for data transferred to or from Amazon Redshift and Amazon S3 within the same AWS Region.
Because of this, you should evaluate how many days you need to keep automated snapshots and configure their retention period accordingly, and delete any manual snapshots that you no longer need.įor more information on working with Redshift Snapshots, please visit the following URL:

After you reach the free snapshot storage limit, you are charged for any additional storage at the normal rate. Ensure that CloudWatch metrics are disabled.Īmazon Redshift provides free storage for snapshots that is equal to the storage capacity of your cluster until you delete the cluster. Ensure VPC Enhanced Routing is enabled.ĭ. Ensure that unnecessary manual snapshots of the cluster are deleted.Ĭ. Use Spot Instances for the underlying nodes in the cluster.ī.
As an architect, which of the following would you consider to ensure cost-effectiveness?Ī. The Redshift cluster is required to be used in a cost-effective manner. A company currently uses Redshift in AWS. If Enhanced VPC Routing is not enabled, Amazon Redshift routes traffic through the Internet, including traffic to other services within the AWS network.įor more information on Redshift Enhanced Routing, please visit the following URL: When you use Amazon Redshift Enhanced VPC Routing, Amazon Redshift forces all COPY and UNLOAD traffic between your cluster and your data repositories through your Amazon VPC. Enable Amazon Redshift Enhanced VPC Routing.ĪWS Documentation mentions the following:
