Difference Between Hadoop and Redshift

Hadoop is an open source framework developed by Apache Software Foundation with its main benefits of scalability, reliability and distributed computing. Data processing, Storage, Access, Security are several types of features available on Hadoop Ecosystem. The origin of Hadoop came from the published paper of Google File System.

Redshift is a cloud hosting web service developed by Amazon Web Services unit within Amazon.com Inc., Out of the existing services provided by Amazon, Redshift is the fastest growing service ever. It is used to design a large-scale data warehouse in the cloud.

Hadoop HDFS has high fault tolerance capability and was designed to run on low-cost hardware systems. HDFS has a high throughput which means able to handle large amounts of data with parallel processing capability.

Redshift is a petabyte-scale data warehouse service that is fully managed and cost-effective to operate on large datasets. Redshift provides a console to create and manage Amazon Redshift clusters.

Hadoop can handle a minimum typical size of TeraBytes to GigaBytes of files within in its system. HDFS is master-slave architecture consisting of Name Nodes and Data Nodes where Name Node contains metadata and Data Node contains real data to be processed or operated.

RedShift uses different data loading techniques such as BI (Business Intelligence) reporting, analytical tools, and data mining. The core component of Redshift Data Warehouse is a cluster.

Key Differences between Hadoop vs Redshift:

Below is the Key Differences between  Hadoop vs  Redshift are as Follows

1.The Hadoop HDFS (Hadoop Distributed File System) Architecture is having Name Nodes and Data Nodes, whereas Redshift has Leader Node and Compute Nodes where Compute nodes will be partitioned as Slices.

2. Hadoop provides command line interface to interact with file system whereas RedShift has Management console to interact with Amazon storage services such as S3, DynamoDB etc.,

3.The database operations are to be configured by developers. In Redshift automates the database operations by parsing the execution plans.

4.Hadoop has several third-party tools support to be integrated easily whereas Redshift supports only the products developed by Amazon in its cloud.

5.In terms of Hadoop architectural design, network, storage, security, and performance have been considered primary elements whereas in Redshift these elements can be easily and flexibly configured using Amazon cloud management console.

6.Hadoop is a File System architecture based on Java Application Programming Interfaces (API) whereas Redshift is based on Relational model Database Management System (RDBMS).

7.Hadoop can have integrations with different vendors and Redshift has no support in this case where Amazon is there only vendor. What if a user is dissatisfied with the service? In this case, Hadoop is an advantage.

8.Most of the existing companies are still using Hadoop whereas new customers are choosing RedShift.

9.In terms, performance Hadoop always lacks behind and Redshift always wins over in the case of query execution on large volumes of data.

10.Hadoop uses Map Reduce programming model for running jobs. Amazon Redshift uses Amazon’s Elastic Map Reduce.

11.Hadoop uses Map Reduce programming model for running jobs. Amazon Redshift uses Amazon’s Elastic Map Reduce.

12.Hadoop is preferable to run batch jobs daily that becomes cheaper whereas Redshift comes out cheaper in case of Online Analytical Processing (OLAP) technology that exists behind many Business Intelligence tools.

13.Hadoop is 10 times slower than Redshift in running queries in the similar way Hadoop is 10 times costlier than Redshift resulting in Hadoop to be least chosen before Redshift.

14.In terms of Data Loading too, Hadoop has been behind Redshift in terms if hours are taken by the system to load data from the storage into its file processing system.

15.Hadoop can be used for low-cost storages, data archiving, data lakes, data warehousing and data analytics whereas Redshift comes under Data warehouse capabilities causing to limit the multi-purpose usage.

16.Hadoop platform provides support to various external vendors and its own Apache projects such as Storm, Spark, Kafka, Solr etc., and on the other side Redshift has limited integration support with its only Amazon products

Conclusion – Hadoop vs Redshift

The final statement to conclude the big winner in this comparison is Redshift that wins in terms of ease of operations, maintenance, and productivity whereas Hadoop lacks in terms of performance scalability and the services cost with the only benefit of easy integration with third-party tools and products. Redshift has been recently evolving with tremendous growth and acceptance by many customers and clients due to its high availability and less cost of operations compared to Hadoop makes it more and more popular. But, till now most of the existing Fortune 1000 companies have been using Hadoop platforms in its architectures to manage the customer data.

In most of the cases RedShift has been the best choice to consider for the business purposes by any client or customer in order handle the large and sensitive data of any financial institutions or public information with more data integrity and security.

Apart from this Hadoop has its own advantages being open source project and had been available for many years also cause the existing systems to be replaced as a cost incurring process. The product should be finally chosen based on the requirement and flexibility rather than pricing or popularity based on the driven business needs.
