HomeNet Automotive, a division of Cox Automotive, is a leading provider of online inventory management and marketing solutions for car dealers. Cox turned to Couchbase for help when HomeNet had to scale its system from handling 6 million cars per day to 100 million. Couchbase was first implemented as a caching solution, then expanded to additional use cases. Cox uses SQL Server hardware but relies on Couchbase for speed, flexibility, and dependability to meet its high-throughput requirements for nontransactional data.


"We were looking for something we could do in a period of weeks not months, to take load off the SQL servers and provide scalability."

  • Had to scale from supporting 6 million car listings per day to 100+ million

  • SQL Server crashed when Cox tried to list all of its staging tables

  • Needed to implement caching ASAP to relieve pressure on the database


  • It’s easy to add nodes to the Couchbase cluster as needed with no downtime
  • Took only two weeks to get the Couchbase cache live in production
  • Rapidly expanded Couchbase to more use cases, including the system of record
