How Charles Schwab modernized its database architecture for real-time intraday operations

Charles Schwab modernized its database architecture for real-time intraday operations by adopting Aerospike as its intraday system of record. The company faced challenges with their existing database architecture, including limited scalability and availability issues. To address these issues, they established new architectural principles such as a single operational data store, no local caching, maximum code reuse, and CLR/JVM focus. By adopting Aerospike, Charles Schwab achieved 99.99% availability during intraday hours and can handle about 150 TB in each zone with 75 billion daily transactions.
