Abstract: A website hosting system includes a request routing node and a plurality of security termination nodes coupled to the request routing node. Each security termination node is configured to secure connections between servers hosting websites and customers of the websites in accordance with a predetermined quality of service level. The request routing node balances incoming requests for secure websites among the security termination nodes based on an application-specific parameter (e.g., quantity of items in a product catalog, location, etc.).

Abstract: In at least one embodiment of an ecommerce system, payment data is divided into proper subsets and distributed among multiple data processing systems, and each of the data processing systems stores less than all of the subsets of the payment data after the subsets of payment data are distributed and until at least sending the payment data to a payment authorization system for processing. In at least one embodiment, distributing proper subsets of the payment data among multiple data processing systems enhances security of the payment data by limiting an amount of time and the locations in which a complete set of payment data is persisted.
