Amazon relies on a Linux-based technology infrastructure centered around three large Linux databases totaling 7.8 terabytes in size in 2005. The data warehouse is divided into functions for querying, storing historical data, and extracting, transforming, and loading data from other sources. During peak periods like the 2003 holiday season, Amazon was able to process up to 1 million shipments and 20 million inventory updates in a single day. The company uses Netscape Secure Commerce Server and SSL encryption to securely handle transactions on its website.
