EG`, a UK-based commercial property data service company, has transformed its business by adopting a modern, event-driven architecture powered by MongoDB. The company's platform is built on a microservices-inspired architecture called "pods," each serving specific data products and audiences. MongoDB serves as the central database, storing all property details and transactions, and acts as the system of record for updates. The company uses MongoDB's flexible data model, rich query language, and indexing to enable fast development and improve its self-healing replica set architecture. With MongoDB, EG can deploy new features 50 times per month, achieving always-on availability and enabling faster time-to-market for new products.
