How Amazon QuickSight Works

Amazon QuickSight is a fully managed business intelligence service.
It connects to your data in the cloud and combines data from many different sources.
It saves your prepared data either in SPICE memory or as a direct query.
You can use a variety of data sources for analysis.
When you create an analysis, the typical workflow includes creating a new analysis, adding new or existing datasets, choosing fields to create the first chart, adding more charts, tables, or insights to the analysis, and publishing the analysis as a dashboard to share it with other people.

It powers data-driven organizations with unified business intelligence at hyperscale.
All users can meet varying analytic needs from the same source of truth through modern interactive dashboards, paginated reports, embedded analytics, and natural language queries.
It allows your business to deliver easy-to-understand insights to users, regardless of their location.
It offers user-management tools that allow users to easily manage and scale systems.

There are quotas for Amazon QuickSight per AWS account, per AWS Region.
There are limits on Amazon QuickSight resources for each file system in an AWS Region.
For operations such as connecting, sampling data for a dataset, and generating visuals, timeouts can occur.
The current way QuickSight limits the number of points displayed in a scatter plot is less than ideal and confusing.
You can add more than 30 visuals with the limit being 50. You get a warning of possible performance regression.

Amazon QuickSight has several essential use cases for Data Analysts and Data Engineers such as interactive ad-hoc data exploration and visualization.
