Houghton Mifflin Harcourt, a nearly 200-year-old publishing company, faced challenges in gaining real-time visibility into their AWS spend, optimizing DevOps monitoring, and gathering performance metrics for its online educational business. To address these challenges, the company chose InfluxDB Enterprise, an enterprise-grade time series platform, to handle large cardinality and provide high availability, horizontal scalability, and LDAP and OAuth support. Additionally, they deployed Telegraf, a metrics collection agent, to optimize spend and performance, and Kapacitor, a native data processing engine, to process stream and batch data from InfluxDB in real-time. With InfluxDB, Houghton Mifflin Harcourt gained real-time visibility into its AWS spend, optimized DevOps monitoring, and gathered performance metrics, enabling the company to make data-driven decisions and improve its operations.
