The main motivation for people trying out MongoDB and adopting it is to be more productive, as stated by its CTO and co-founder Eliot Horowitz. The evolution of MongoDB has been driven by this goal of empowering software engineers through efficient app development. The JSON-based document model provides a fundamentally easier data structure for developers to work with, making it more natural for programming languages to work with. This data model reduces friction for developers, not only reducing their headaches but also having a direct impact on the bottom line. MongoDB's evolution alongside cloud computing and service-oriented architectures has been rooted in unburdening individual developers, allowing them to use third-party services instead of coding necessary functionality from scratch. The conversation between Eliot Horowitz and Jeff Meyerson discusses how MongoDB has evolved and its future as well as its internal use in a hybrid cloud configuration.
