MongoDB Atlas`, a cloud-based database as a service, has been chosen by `HT2 Labs` to power their open-source `Learning Locker` platform, which is used by educational institutions and companies like Xerox and Jisc. The migration from `ObjectRocket` was driven by cost savings, increased scalability, and improved security features in MongoDB Atlas. With the help of MongoDB's horizontal scale-out architecture, HT2 Labs can handle large volumes of learning data, enabling personalized analytics and reporting for their clients.
