A data warehouse is a data storage center that collects data from different resources. Raw data collected from the resources are transformed into useful information and presented in the form of reports to users. These reports are then used to perform daily tasks by the users.

Traditional data warehouses existed for a very long time and posed different challenges. It is very expensive to set up and run a traditional data warehouse from scratch. The size of the data size is directly proportional to the cost of infrastructure, in turn demanding throughput planning and commitment from the management. Amazon Redshift, a modern data warehouse, has helped many firms to overcome these challenges using its unique architecture and business model. 

Amazon Redshift, a flagship product of the cloud computing platform – Amazon Web Services, is a modern data warehouse product built on a sophisticated warehouse, Massive Parallel Processing architecture, and column-based database architecture. The product is highly reliable, scalable, and time & cost-effective in terms of data analysis. It eliminates several boring tasks such as taking continuous backup to avoid data loss, database administration tasks, and also encrypts data through its built-in security features.

What makes Amazon Redshift standout?

Traditional data warehouses need continuous infra upgrades, owing to difficulties in setting up and  running data warehouse in short duration abreast increases in the data size. It takes only minutes to create a cluster in Amazon Redshift using the console. Amazon Redshift enables a requirement-specific, dynamic scaling of the infrastructure, which in turn has made it a highly reliable and fast performing solution to many companies.

Unique Architecture

Traditional data warehouses use row-based database architecture, which curtails the database performances. Architects, while querying should take extra care to reduce the time taken, failing which, time taken for a few columns might increase. Amazon Redshift uses column-based database architecture to compress the data, free up memory for data analysis, and improve query performance.

Multi-Node Cluster

Amazon Redshift uses Massive Parallel Processing architecture to break large data sets into chunks and process the data. The design creates a lead node that assigns chunks to several compute nodes. The lead node gathers results from the individual nodes and presents it to the client application. The client application reads the data directly from Amazon Redshift, enabling analysts to perform tasks using this data.

Smart Compilation

The platform distributes the compiled code across the cluster after the query is compiled. It eliminates additional processing time, allowing quicker execution. 

High Security

Amazon Redshift is equipped very well to protect the data. It has in-built security features like Virtual Private Cloud and data encryption to secure data. It also has multiple access controls to restrict inbound and outbound accessibility.

Low cost

Amazon Redshift does not demand upfront costs. It uses pay as you go model, and contract commitments can be eliminated anytime. Pricing starts from as low as $0.25/hour for a 160GB DC1 and $0.85/hour for a larger node 2TB version. Studies suggest that it only takes 1/10th of the total cost of the traditional on-premise warehouse to setup Amazon Redshift.

Managing Data Stack

Amazon Redshift has data integration, BI, system integration, and consulting partners to load or extract data for analytics. Data Integration partners help to integrate data such as ETL/ELT and data modeling. BI partners help to extract reports, analyze data, and visualize data for a meaningful purpose. System integration and consulting partners provide expert opinions and training on Amazon Redshift.

Amazon Redshift is changing the landscape of the data warehouse industry without compromising on features and performance. The customer base of Amazon Redshift ranges from large corporations that consume multi-petabyte to start-ups that consume a few hundred gigabytes. With the dramatically declining costs of setting up data warehouse systems, numerous firms are getting pulled towards Amazon Redshift.
