MongoDB Atlas is a fully managed cloud database service that lets you run MongoDB on AWS, Azure, or Google Cloud Platform. It handles the provisioning, scaling, updates, backups, and security of your MongoDB clusters. It also provides features like data federation, charts, BI connector, online archive, app services, and support.
The pricing of MongoDB Atlas depends on the cluster configuration, data transfer, backup services, and cloud provider. You can start with a free tier that offers 512MB of storage and shared RAM. The next tier is the shared tier, which offers 2GB or 5GB of storage and costs $9 or $25 per month respectively. The shared tier is suitable for learning and prototyping. The dedicated tier offers more storage, RAM, and performance options, starting from $57 per month for a 2GB RAM/10GB storage cluster. The dedicated tier is suitable for production applications with sophisticated workload requirements. You can also choose to enable serverless database, which charges you based on the read and write operations, storage, backup, and data transfer of your database. The serverless database is suitable for serverless applications with variable or infrequent traffic.
