Introduction

Amazon Redshift is a data warehouse product part of Amazon Web Services. The range of its datasets is from 100s of gigabytes to a petabyte. Amazon Redshift used parallel processing and compression to decrease the command execution time. Redshift uses this technique to perform operations on billions of rows at once.

 

Features of Amazon Redshift

  1. SSL Encryption: The connections between clients and Redshift are encrypted through SSL encryption.
  2. Supports VPC: The users can launch Redshift within the VPC and control the access to the cluster through the virtual networking environment.
  3. Scalable: We can quickly scale the number of nodes in our Redshift data warehouse. We can also scale over the storage capacity without compromising the performance. 
  4. Cost-Effective: Amazon Redshift is a cost-effective alternative as there are no up-front costs, no long-term commitments, and an on-demand pricing structure.
