O Amazon Redshift é um data warehouse rápido, gerenciado e em escala de petabytes que torna mais simples e econômica a análise de todos os seus dados usando as ferramentas de inteligência de negócios de que você já dispõe. Comece aos poucos, por apenas 0,25 USD por hora, sem compromissos, e aumente a escala até petabytes por 1.000 USD por terabyte por ano, menos de um décimo do custo das soluções tradicionais. Normalmente, os clientes relatam uma compactação de 3x, que reduz seus custos para 333 USD por terabyte não compactado por ano.

Hinweis der Redaktion
- This is the AWS Big Data portfolio. We have tools like Direct Connect and Import Export that can bring in a lot of data. We can persist that data into a number of storage services from S3 to DynamoDB to EMR and RedShift for further analysis. Amazon Redshift provides a fast, fully managed, petabyte-scale data warehouse for less than $1000 per terabyte per year. Amazon Elastic MapReduce provides a managed, easy to use analytics platform built around the powerful Hadoop framework. Recently we announced Amazon Kinesis, a managed service for real-time processing of streaming big data. Amazon Glacier allows you to backup and archive an unlimited amount of data at just 1 cent per GB per month. Automate and schedule big data processing workloads with Data Pipeline. The tools to support big data collection, computation along with collaboration and sharing are all available in a couple of clicks, with AWS.
- Redshift value proposition: fast, simple, cost-effective data warehousing. Massively parallel and columnar technology. Easily scalable to petabytes or more. Makes administration simple, no DBA needed. You can choose from hard disk drive or solid state drive platform depending on your needs. All this for $1,000/TB/year, which is one-tenth of the cost of traditional data warehousing solutions.
- Our view of data warehousing and why we built Amazon Redshift. We want to make data warehousing fast, inexpensive and easy to use for companies of all sizes For Enterprises, benefits are: 1/10th cost, easy to provision and manage, productive DBAs For Big data companies: 10x faster, use standard SQL-no need to write custom code, use existing BI tools For SaaS: analysis in-line with process flows, pay as you go, grow as you need, managed availability & DR
- Amazon Redshift has been ranked as a leader in the recent data warehousing Forrester Wave
- Nasdaq security – Ingests 5B rows/trading day, analyzes orders, trades and quotes Yelp – 10s of millions of ads/day, 250M mobile events/day, analyzes ad campaign performance and new feature usage Desk.com – Ingests 200K case related events/hour and runs a user facing portal on Redshift
- High level overview of Amazon Redshift Architecture – MPP based with leader node that acts as a SQL end point and coordinates query execution with compute nodes. The computes store data locally in columnar format.
- Column storage fetches only those columns that are required for queries Customer typically get 2-4x compression. Compression also implies less I/O Zone maps: Each column is divided into 1MB blocks, we store the min/max values of each block in memory. We are able to quickly identify the blocks that are required to be fetched for a query Direct-attached storage/large block sizes also enable fast I/O
- All the operations that you care about from a database management and performance perspective are all parallelized, and hence scale horizontally with the number of nodes
- We work with EC2 and infrastructure teams closely to optimize the h/w for data warehousing needs.
- We work with EC2 and infrastructure teams closely to optimize the h/w for data warehousing needs.
- Prices start at $1,000/TB/yr. for a 3 year DS2.8XL RI. RIs provide up to 70% discounts.
- Backups are managed, continuous and incremental Multiple copies are made within and outside the cluster on S3 Streaming restore =>While restore happens in the background, cluster is made available for reads/write within minutes of initiating the restoring operation (whether the backup is for a 1TB or a 100TB cluster)
- Redshift monitors the health of a variety of components and failure conditions within an AZ and recovers from them automatically For AZ/regional level disasters, streaming restore will help get back to business within minutes
- From the time data is generated to the time it is queried, data can be encrypted end-to-end on Redshift
- Pace of innovation – Continuous deployment, different model, Oracle/Teradata etc. still took a 6 month deployment plan vs. us
- We respect the investments you made in your analytics platforms and work with a variety of ETL, BI and SI vendors. Standard JDBC/ODBC drivers make the integration process seamless but we work with these vendors closely to certify the joint platforms
- We believe in SOA, pick and choose the components that work for your use case instead of bundling it all
- Sorted columns enable fetching the minimum number of blocks required for query execution. In this example, an unsorted table al most leads to a full table scan O(N) and a sorted table leads to one block scanned O(1).
- Redshift works with customer’s BI tool of choice through Postgres drivers and a JDBC, ODBC connection. A number of partners shown here have certified integration with Redshift, meaning they have done testing to validate/build Redshift integration and make using Redshift easy from a UI perspective. If there are tools customer’s use not shown we can work with Redshift on getting them integrated.
