Amazon Redshift is a fast, fully managed data warehouse that makes it simple and cost-effective to analyze all your data using standard SQL and your existing Business Intelligence (BI) tools. It allows you to run complex analytic queries against petabytes of structured data, using sophisticated query optimization, columnar storage on high-performance local disks, and massively parallel query execution. Most results come back in seconds. With Amazon Redshift, you can start small for just $0.25 per hour with no commitments and scale out to petabytes of data for $1,000 per terabyte per year, less than a tenth the cost of traditional solutions.

Amazon Redshift also includes Redshift Spectrum, allowing you to directly run SQL queries against exabytes of unstructured data in Amazon S3. No loading or transformation is required, and you can use open data formats, including Avro, CSV, Grok, ORC, Parquet, RCFile, RegexSerDe, SequenceFile, TextFile, and TSV. Redshift Spectrum automatically scales query compute capacity based on the data being retrieved, so queries against Amazon S3 run fast, regardless of data set size. Learn more about Redshift Spectrum »

Fast, Consistent Performance


Amazon Redshift delivers fast query performance by using columnar storage technology to improve I/O efficiency and by parallelizing queries across multiple nodes. Data load speed scales linearly with cluster size, with integrations to Amazon S3, Amazon DynamoDB, Amazon EMR, Amazon Kinesis, and any SSH-enabled host.

Highly Scalable


You only pay for what you use. You can have unlimited number of users doing unlimited analytics on all your data for just $1000 per terabyte per year, 1/10th the cost of traditional data warehouse solutions. Most customers see 3-4x reduction of data size after compression, reducing their costs to $250-$333 per uncompressed terabyte per year.

Fast, Consistent Performance


Redshift Spectrum enables you to run queries against exabytes of data in Amazon S3 as easily as you run queries against petabytes of data stored on local disks in Amazon Redshift, using the same SQL syntax and BI tools you use today. You can store highly structured, frequently accessed data on Redshift local disks, keep vast amounts of unstructured data in an Amazon S3 “data lake”, and query seamlessly across both.



Amazon Redshift allows you to easily automate most of the common administrative tasks to manage, monitor, and scale your data warehouse. By handling all these time-consuming, labor-intensive tasks, Amazon Redshift frees you up to focus on your data and business.

Highly Scalable


You can easily resize your cluster up and down as your performance and capacity needs change with just a few clicks in the console or a simple API call.



Security is built-in. You can encrypt data at rest and in transit using hardware-accelerated AES-256 and SSL, isolate your clusters using Amazon VPC and even manage your keys using AWS Key Management Service (KMS) and hardware security modules (HSMs).

Event Driven Programming


Amazon Redshift supports standard SQL and provides custom JDBC and ODBC drivers that you can download from the console, allowing you to use a wide range of familiar SQL clients. You can also use standard PostgreSQL JDBC and ODBC drivers.

Optimized for Data Warehousing

Amazon Redshift uses a variety of innovations to obtain very high query performance on datasets ranging in size from a hundred gigabytes to an exabyte or more. For petabyte-scale local data, it uses columnar storage, data compression, and zone maps to reduce the amount of I/O needed to perform queries. Amazon Redshift has a massively parallel processing (MPP) data warehouse architecture, parallelizing and distributing SQL operations to take advantage of all available resources. The underlying hardware is designed for high performance data processing, using local attached storage to maximize throughput between the CPUs and drives, and a 10GigE mesh network to maximize throughput between nodes. For exabyte-scale data in Amazon S3, Amazon Redshift generates an optimal query plan that minimizes the amount of data scanned and delegates the query execution to a pool of Redshift Spectrum instances that scales automatically, so queries run quickly regardless of data size.

Petabyte Scale

With a few clicks in console or a simple API call, you can easily change the number or type of nodes in your data warehouse and scale up all the way to a petabyte or more of compressed user data. Dense Storage (DS) nodes allow you to create very large data warehouses using hard disk drives (HDDs) for a very low price point. Dense Compute (DC) nodes allow you to create very high performance data warehouses using fast CPUs, large amounts of RAM and solid-state disks (SSDs). While resizing, Amazon Redshift allows you to continue to query your data warehouse in read-only mode until the new cluster is fully provisioned and ready for use.

Query your Amazon S3 “data lake”

Redshift Spectrum enables you to run queries against exabytes of unstructured data in Amazon S3, with no loading or ETL required. When you issue a query, it goes to the Amazon Redshift SQL endpoint, which generates and optimizes a query plan. Amazon Redshift determines what data is local and what is in Amazon S3, generates a plan to minimize the amount of Amazon S3 data that needs to be read, requests Amazon Redshift Spectrum workers out of a shared resource pool to read and process data from Amazon S3, and pulls results back into your Amazon Redshift cluster for any remaining processing.

No Up-Front Costs

You pay only for the resources you provision. You can choose On-Demand pricing with no up-front costs or long-term commitments, or obtain significantly discounted rates with Reserved Instance pricing. On-Demand pricing starts at just $0.25/hour per 160GB DC1.Large node or $0.85/hour per 2TB DS2.XLarge node. With Partial Upfront Reserved Instances, you can lower your effective price to $0.10/hour per DC1.Large node ($5,500/TB/year) or $0.228/hour per DS2.XLarge node ($999/TB/year). Redshift Spectrum queries are priced at $5/TB scanned from S3. For more information, see the Amazon Redshift Pricing page.

Fault Tolerant

Amazon Redshift has multiple features that enhance the reliability of your data warehouse cluster. All data written to a node in your cluster is automatically replicated to other nodes within the cluster and all data is continuously backed up to Amazon S3. Amazon Redshift continuously monitors the health of the cluster and automatically re-replicates data from failed drives and replaces nodes as necessary.

Automated Backups

Amazon Redshift automatically and continuously backs up new data to Amazon S3. It stores your snapshots for a user-defined period from 1 up to 35 days. You can take your own snapshots at any time, and they are retained until you explicitly delete them. Amazon Redshift can also asynchronously replicate your snapshots to S3 in another region for disaster recovery. Once you delete a cluster, your system snapshots are removed, but your user snapshots are available until you explicitly delete them.

Fast Restores

You can use any system or user snapshot to restore your cluster using the AWS Management Console or the Amazon Redshift APIs. Your cluster is available as soon as the system metadata has been restored and you can start running queries while user data is spooled down in the background.


With just a couple of parameter settings, you can set up Amazon Redshift to use SSL to secure data in transit and hardware-accelerated AES-256 encryption for data at rest. If you choose to enable encryption of data at rest, all data written to disk will be encrypted as well as any backups. By default, Amazon Redshift takes care of key management but you can choose to manage your keys using your own hardware security modules (HSMs), AWS CloudHSM, or AWS Key Management Service.

Network Isolation

Amazon Redshift enables you to configure firewall rules to control network access to your data warehouse cluster. You can run Amazon Redshift inside Amazon VPC to isolate your data warehouse cluster in your own virtual network and connect it to your existing IT infrastructure using industry-standard encrypted IPsec VPN.

Audit and Compliance

Amazon Redshift integrates with AWS CloudTrail to enable you to audit all Redshift API calls. Amazon Redshift also logs all SQL operations, including connection attempts, queries and changes to your database. You can access these logs using SQL queries against system tables or choose to have them downloaded to a secure location on Amazon S3. Amazon Redshift is compliant with SOC1, SOC2, SOC3 and PCI DSS Level 1 requirements. For more details, please visit AWS Cloud Compliance.
