Amazon QuickSight is a native AWS service that is designed to simplify the way we understand our data. As a fast, cloud-powered BI service, QuickSight lets you generate interactive dashboards, perform ad hoc analysis, and obtain insights from your data, regardless of its magnitude. All these activities contain elements of data visualization to facilitate the interpretation of data sets.

A developer would typically use QuickSight to create and publish dashboards containing visualizations for end-users. The service provides ‘Autograph,’ a feature that enables the selection of the most suitable visuals based on the data fields chosen.

Here’s an example of just how easy it is to create a visualization:

  • Import your data (QuickSight can connect to various data sources including Amazon RDS, Amazon Aurora, Amazon Redshift, and even Excel files).
  • Choose the data you want to visualize.
  • QuickSight will automatically suggest the best visualization based on your selected data, or you can choose your preferred visualization option.

The resulting data visualization can be a bar graph, pie chart, scatter plot, heat map, among others.

AWS Data Pipeline – Data Movement and Transformation

While Amazon QuickSight primarily focuses on the aspect of visualizing and understanding data, AWS Data Pipeline focuses on the delivery of data from different AWS services and on-premises data sources. Data Pipeline enables you to integrate data across different AWS services and make it ready for visualization and analysis.

Some use cases of AWS Data Pipeline include:

  • Migrating on-premise data to AWS for better scalability.
  • Archive data to Amazon S3 or Glacier for backup or long-term storage.
  • Data transformation for analysis (for instance, the data ingested may require cleaning or formatting before it can be used for visualization).

Using QuickSight and Data Pipeline Together

When used together, AWS Data Pipeline can retrieve data from assorted sources, process and ready it for analysis, and QuickSight can then take this data and create meaningful visualizations. AWS Data Pipeline can access data from Amazon DynamoDB, Amazon RDS, and other JDBC databases. After extraction, data can be processed in compute services like Amazon EMR and then stored in services like Amazon S3. The processed data residing in S3 can then be visualized in Amazon QuickSight for insightful business intelligence.

Understanding these AWS tools related to data visualization significantly increases your chances of passing the AWS Certified Developer – Associate (DVA-C02) exam. Data visualization is a potent tool in the hands of a developer, representing complex data in an easily interpretable format, facilitating quicker and more effective decision-making.

As you study for your AWS Certified Developer – Associate (DVA-C02) exam, remember to get some hands-on practice in these services. AWS offers free tier access for new accounts, providing a perfect way to experiment with these services without incurring additional costs.
