January 2014 Summaries

AppNexus, a leading advertising technology company, has significantly improved its performance, reliability, and serviceability while reducing server count through the use of Aerospike's flash-optimized in-memory NoSQL database built on Intel solid-state drives (SSDs). By integrating Intel SSDs in a wide SATA configuration, AppNexus reduced its cluster size from about 50 machines to 8 machines per cluster. This has enabled the company to operate at massive scale while paying close attention to the economics of their platform.
