Data Processes
Marketplace API does not rely on any live integration with external systems for its data. All data is loaded via ETL processes that occur either on fixed intervals (coverage data) or as updated data becomes available (plan data).
Performance
Because Marketplace API does not rely on external data and is read-only, it is highly horizontally scalable, via adding new application servers (via auto-scaling) and, rarely, via adding additional database replicas.
