Amazon Redshift costs less to operate than any other data warehouse. Start small at $0.25 per hour and scale up to petabytes of data and thousands of concurrent users. Choose what is right for your business needs, with the ability to grow storage without over-provisioning compute, and the flexibility to grow compute capacity without increasing storage costs.
What to expect
First, choose the best cluster configuration for your needs by learning more about the node types in the following section. You can quickly scale your cluster, pause and resume the cluster, and switch between node types with a single API call or a few clicks in the Amazon Redshift console. You’ll see on-demand pricing before making your selection, and later you may choose to purchase reserved nodes for significant discounts.
Once you make your selection, you may wish to use elastic resize to easily adjust the amount of provisioned compute capacity within minutes for steady-state processing. With resize scheduler, you can add and remove nodes on a daily or weekly basis to optimize cost and get the best performance. For dynamic workloads, you can use Concurrency Scaling to automatically provision additional compute capacity and only pay for what you use on a per-second basis after exhausting the free credits (see Concurrency Scaling pricing).
Amazon Redshift node types
Redshift managed storage uses large, high-performance SSDs in each RA3 node for fast local storage and Amazon S3 for longer-term durable storage. If the data in a node grows beyond the size of the large local SSDs, Redshift managed storage automatically offloads that data to Amazon S3. You pay the same low rate for Redshift managed storage regardless of whether the data sits in high-performance SSDs or S3. For workloads that require ever-growing storage, managed storage lets you automatically scale your data warehouse storage capacity without adding and paying for additional nodes.
DC2 nodes allow you to have compute-intensive data warehouses with local SSD storage included. You choose the number of nodes you need based on data size and performance requirements. DC2 nodes store your data locally for high performance, and as the data size grows, you can add more compute nodes to increase the storage capacity of the cluster. For datasets under 1TB uncompressed, we recommend DC2 node types for the best performance at the lowest price. If you expect your data to grow, we recommend using RA3 nodes so you can size compute and storage independently to achieve the best price and performance.
DS2 nodes enable you to create large data warehouses using hard disk drives (HDDs), and we recommend using RA3 nodes instead. If you are using DS2 nodes, see Overview of RA3 Node Types in the Cluster Management Guide for upgrade guidelines. Customers using eight or more nodes of DS2.xlarge, or any number of DS2.8xlarge nodes, can now upgrade to RA3 and get 2x more storage and better performance for the same on-demand cost.
Redshift capabilities with pay-as-you-go pricing
- Amazon Redshift Spectrum pricing: enables you to run SQL queries directly against the data in your S3 data lake, out to exabytes - you simply pay for the number of bytes scanned.
- Concurrency Scaling pricing: each cluster earns up to one hour of free concurrency scaling credits per day, which is sufficient for 97% of customers. This enables you to provide consistently fast performance, even with thousands of concurrent queries and users. You simply pay a per-second on-demand rate for usage that exceeds the free credits.
- Redshift managed storage pricing: gives you the flexibility to pay only for the data that you store in RA3 clusters independent of number of compute nodes provisioned. You simply pay hourly for the total amount of data in managed storage.
Amazon Redshift on-demand pricing allows you to pay for capacity by the hour with no commitments and no upfront costs, you simply pay an hourly rate based on the type and number of nodes in your cluster. Partial hours are billed in one-second increments following a billable status change such as creating, deleting, pausing or resuming the cluster. The pause and resume feature allows you to suspend on-demand billing during the time the cluster is paused. During the time that a cluster is paused you only pay for backup storage. This frees you from planning and purchasing data warehouse capacity ahead of your needs, and enables you to cost-effectively manage environments for development or test purposes.
*Total addressable storage capacity in the managed storage with each RA3 node.
Calculating your effective price per TB per year for on-demand
For On-Demand, the effective price per TB per year is the hourly price for the instance, times the number of hours in a year, divided by the number of TB per instance. For RA3, data stored in managed storage is billed separately based on actual data stored in the RA3 node types; effective price per TB per year is calculated for only the compute node costs.
Redshift Spectrum pricing
Amazon Redshift Spectrum allows you to directly run SQL queries against exabytes of data in Amazon S3. You are charged for the number of bytes scanned by Redshift Spectrum, rounded up to the next megabyte, with a 10MB minimum per query. There are no charges for Data Definition Language (DDL) statements like CREATE/ALTER/DROP TABLE statements for managing partitions, and failed queries.
You can improve query performance and reduce costs by storing data in a compressed, partitioned, columnar data format. If you compress data using one of Redshift Spectrum’s supported formats, your costs will go down because less data is scanned. Similarly, if you store data in a columnar format, such as Parquet or ORC, your charges will also go down because Redshift Spectrum only scans columns needed by the query.
You are charged for the Amazon Redshift cluster used to query data with Redshift Spectrum. Redshift Spectrum queries data directly in Amazon S3. You are charged standard S3 rates for storing objects in your S3 buckets, and for requests made against your S3 buckets. For details, refer to Amazon S3 rates.
If you use the AWS Glue Data Catalog with Amazon Redshift Spectrum, you are charged standard AWS Glue Data Catalog rates. For details, refer to AWS Glue pricing.
When using Amazon Redshift Spectrum to query AWS Key Management Service (KMS) encrypted data in Amazon S3, you are charged standard AWS KMS rates. For details, refer to AWS KMS pricing.
Redshift Spectrum pricing examples based on US East (N.Virginia) price
Consider a table with 100 equally sized columns stored in Amazon S3 as an uncompressed text file with a total size of 4 terabytes. Running a query to get data from a single column of the table requires Redshift Spectrum to scan the entire file, because text formats cannot be split. This query would scan 4 terabytes and cost $20. ($5/TB * 4TB = $20)
If you compress your file using GZIP, you may see a 4:1 compression ratio. In this case, you would have a compressed file size of 1 terabyte. Redshift Spectrum has to scan the entire file, but since it is one-fourth the size, you pay one-fourth the cost, or $5. ($5/TB * 1TB = $5)
If you compress your file and convert it to a columnar format like Apache Parquet, you may see a 4:1 compression ratio and have a compressed file size of 1 terabyte. Using the same query as above, Redshift Spectrum needs to scan only one column in the Parquet file. The cost of this query would be $0.05. ($5/TB * 1TB file size * 1/100 columns, or a total of 10 gigabytes scanned = $0.05).
Note: The above pricing examples are for illustration purposes only. The compression ratio of different files and columns may vary.
Concurrency Scaling pricing
Amazon Redshift automatically adds transient capacity to provide consistently fast performance, even with thousands of concurrent users and queries. There are no resources to manage, no upfront costs, and you are not charged for the startup or shutdown time of the transient clusters. You can accumulate one hour of concurrency scaling cluster credits every 24 hours while your main cluster is running. You are charged the per-second on-demand rate for a concurrency scaling cluster used in excess of the free credits - only when it's serving your queries - with a one-minute minimum charge each time a concurrency scaling cluster is activated. The per-second on-demand rate is based on the type and number of nodes in your Amazon Redshift cluster.
Concurrency Scaling credits
Amazon Redshift clusters earn up to one hour of free Concurrency Scaling credits per day. Credits are earned on an hourly basis for each active cluster in your AWS account, and can be consumed by the same cluster only after credits are earned. You can accumulate up to 30 hours of free Concurrency Scaling credits for each active cluster. Credits do not expire as long as your cluster is not terminated.
Pricing example for Concurrency Scaling
A 10 DC2.8XL node Redshift cluster in the US-East costs $48 per hour. Consider a scenario where two transient clusters are utilized for five minutes beyond the free Concurrency Scaling credits. The per-second on-demand rate for Concurrency Scaling is $48 * 1/3600 = $0.013 per second. The additional cost for Concurrency Scaling in this case is $0.013 per second * 300 seconds * 2 transient clusters = $8. Therefore, the total cost of the Amazon Redshift cluster and the two transient clusters in this case is $56.
Redshift managed storage pricing
You pay for data stored in managed storage at a fixed GB-month rate for your region. Managed storage comes exclusively with RA3 node types and you pay the same low rate for Redshift managed storage regardless of data size. Usage of managed storage is calculated hourly based on the total data present in the managed storage (see example below converting usage in GB-Hours to charges in GB-Month). You can monitor the amount of data in your RA3 cluster via Amazon CloudWatch or the AWS Management Console. You do not pay for any data transfer charges between RA3 nodes and managed storage. Managed storage charges do not include back up storage charges due to automated and manual snapshots (see Backup Storage). Once the cluster is terminated, you continue to be charged for the retention of your manual backups.
Pricing example for managed storage pricing
Let’s first calculate the usage in GB-Hours for the above scenario. For the first 15 days, you will have the following usage in GB-Hours: 100GB x 15 days x ( 24 hours/day) = 36,000 GB-Hours.
At the end of April, all usage in GB-Hours adds to: 36,000 GB-Hours + 36,864,000 GB-Hours = 36,900,000 GB-Hours
Let's convert this to GB-Months: 36,900,000 GB-Hours / 720 hours per month in April = 51,250 GB-Month.
If this data was stored in the US East (Northern Virginia) Region, managed storage will be charged at $0.024/GB-Month. Monthly storage charges for 51,250 GB-Month will be: 51,250 GB-Month x $0.024 per GB-month = $1,230
Total Managed Storage Fee for April = $1,230
Reserved Instance pricing
Reserved Instances are appropriate for steady-state production workloads, and offer significant discounts over On-Demand pricing. Customers typically purchase Reserved Instances after running experiments and proof-of-concepts to validate production configurations.
You can benefit from significant savings over On-Demand rates by committing to use Amazon Redshift for a 1- or 3-year term. Reserved Instance pricing is specific to the node type purchased, and remains in effect until the reservation term ends. Prices include two additional copies of data - one on the cluster nodes and one in Amazon S3. We take care of backup, durability, availability, security, monitoring, and maintenance for you.
There are three options for Reserved Instance pricing:
No Upfront – You pay nothing upfront, and commit to pay monthly over the course of one year.
Partial Upfront – You pay a portion of the Reserved Instance upfront, and the remainder over a one- or three-year term.
All Upfront – You pay for the entire Reserved Instance term (one or three years) with one upfront payment.
Reserved Instances are a billing concept and are not used to create data warehouse clusters. When you make a purchase, you will be charged the associated upfront and monthly fees even if you are not currently running a cluster, or if an existing cluster is paused. To purchase Reserved Instances, visit the Reserved Nodes tab in our Console.
We may terminate the Reserved Instance pricing program at any time. In addition to being subject to Reserved Instance pricing, Reserved Instances are subject to all data transfer and other fees applicable under the AWS Customer Agreement or other agreement with us governing your use of our services.
* The Monthly rate below is the actual hourly rate multiplied by the average number of hours per month.
** The Effective Hourly rate below is the amortized hourly cost of the instance over the entire term, including any upfront payment.
Calculating your effective price per TB per year for Reserved Instances
For Reserved Instances, add the upfront payment to the hourly rate times the number of hours in the term, and divide by the number of years in the term and number of TB per node. For RA3, data stored in managed storage is billed separately based on actual data stored in the RA3 node types; effective price per TB per year is calculated for only the compute node costs.
Backup storage is the storage associated with the snapshots taken for your data warehouse. Increasing your backup retention period or taking additional snapshots increases the backup storage consumed by your data warehouse. Redshift charges for manual snapshots you take using the console, API or CLI. Redshift Automated snapshots, which get created using Redshift's snapshot scheduling feature, are not charged for. Data stored on RA3 clusters is part of Redshift Managed Storage (RMS) and is billed at RMS rates, but manual snapshots taken for RA3 clusters are billed as backup storage at standard Amazon S3 rates outlined on this page. For example, if your RA3 cluster has 10 TB of data and 30 TB of manual snapshots, you would be billed for 10 TB of RMS and 30 TB of backup storage. With dense compute (DC) and dense storage (DS) clusters, storage is included on the cluster and is not billed for separately, but backups are stored externally in S3. Backup storage beyond the provisioned storage size on DC and DS clusters is billed as backup storage at standard Amazon S3 rates. Snapshots are billed until they expire or are deleted, including when the cluster is paused or deleted.
There is no charge for data transferred between Amazon Redshift and Amazon S3 within the same AWS Region for backup, restore, load, and unload operations. For all other data transfers into and out of Amazon Redshift, you will be billed at standard AWS data transfer rates. In particular, if you run your Amazon Redshift cluster in Amazon VPC, you will see standard AWS data transfer charges for data transfers over JDBC/ODBC to your Amazon Redshift cluster endpoint. In addition, when you use Enhanced VPC Routing and unload data to Amazon S3 in a different region, you will incur standard AWS data transfer charges. For more information about AWS data transfer rates, see the Amazon EC2 pricing page.
