Cars24 Improves Search For 300 Million Users With MongoDB Atlas

Cars24, an Indian multinational online car marketplace, has significantly transformed its operations by leveraging MongoDB Atlas, a cloud-based database service, to streamline its architecture and enhance its search capabilities. Initially reliant on legacy databases like Postgres and supplementary search engines such as Elasticsearch, Cars24 faced challenges in synchronization, developer productivity, and operational overhead as it scaled globally. By adopting MongoDB Atlas, the company was able to consolidate its data storage and search functions into a single platform, simplifying its processes and reducing costs by 50% after migrating from ArangoDB. This transition not only enabled real-time search capabilities and improved scalability but also supported the rapid onboarding of new developers familiar with MongoDB. These improvements have allowed Cars24 to focus more on application development and innovation, ultimately enhancing its ability to offer comprehensive services in car sales, insurance, maintenance, and financing.
