The document discusses using cloud infrastructure to provide fast access to large datasets for customers globally. It describes: 1. Creating an Excel plug-in that provides thousands of data points on demand from global servers to customers anywhere in the world. 2. Moving frequently used large datasets to the cloud to enable single millisecond data retrieval times, compared to keeping everything in an on-premise US data center. 3. Employing techniques like smart caching and pre-sending relevant data to optimize performance, based on analyzing usage logs to predict customer needs.
