Powering an online community of coders with MongoDB Atlas` is a story about how CodeBuddies, a free virtual space for independent code learners, used MongoDB Atlas to power their platform. The community was created by Linda Peng and Dhaval Tanna in 2014 as a remote and volunteer-driven space where members could share knowledge and help each other learn. The site uses MeteorJS framework and stores data in a MongoDB database. To migrate from mLab to MongoDB Atlas, the team followed three easy steps: dumping the database, creating a new cluster, and populating it with the dumped data. After the migration, they chose MongoDB Atlas for its performance monitoring tools, professional support, and easy scaling, ensuring their platform is prepared for growth.
