Ticketmaster has shifted its database technology from Oracle and MySQL to MongoDB, citing increased flexibility and performance, decreased costs, and faster time-to-market. The company is using MongoDB for two new apps: TM+, which covers the secondary market, and Concerts, a venue view app with features like session recovery and client reports. Ed Presz, VP of Database Services at Live Nation/Ticketmaster, praises MongoDB's ease of deployment, flexibility, MMS, and Enterprise Support, citing it as a key factor in their transition to an agile devops environment. This shift highlights the benefits of using MongoDB for organizations looking to improve development efficiency and operational performance.
