The Center for Internet Security analyzes billions of network traffic records per day from sensors monitoring government networks. They were struggling to store, access, and query this volume of data in a timely manner using their previous on-premise solution. AWS consultants helped them migrate the data to a data lake on AWS using a multi-stage architecture optimized for both real-time and historical queries. This improved query performance by orders of magnitude, allowing analysis that previously took days or weeks to complete in just minutes.
