In this section, we will upgrade our Redshift data warehouse by enabling Redshift Spectrum, which plays the role of a data lake and compliments our data warehouse. It gives us a powerful and serverless architecture and can handle a tremendous volume of data, which is true big data.
Amazon Spectrum extends Redshift data warehouse out to the Exabytes website. You can get all the benefits of open data formats and inexpensive storage, and we can easily scale out to thousands of nodes. Another benefit is the cost; we pay only for usage and storage using S3, which is fairly small in comparison with an analytical data warehouse.
