MongoDB has become an attractive choice for organizations due to its ability to handle modern, unstructured data growth at a rate of 40% annually, with 90% of that data being unstructured. This requires faster and more efficient application development. Several companies, including Telefonica and Shutterfly, have successfully migrated from traditional relational databases (RDBMS) like Oracle to MongoDB, achieving significant improvements in performance, scalability, and cost savings. For example, a small team at Telefonica was able to build a user data management system in just 3 months using MongoDB, while Shutterfly reduced its data storage costs by 80%.
