Gliph, a secure messaging app startup, transitioned from a proof of concept MongoDB implementation to a production-ready setup using MongoDB Management Service (MMS) to ensure an excellent user experience. Initially, their system was designed to work 99 percent of the time but became unstable as usage increased. To address this, they configured multiple servers for a replica set, scheduled regular backups, and added comprehensive error logging. With MMS, they gained visibility into their queries and system performance, allowing them to uncover inefficiencies such as missing indexes, unnecessary fields in queries, and completely unnecessary queries. By addressing these issues, Gliph improved the stability of their system and provided a better user experience.
