MongoDB Scaling and Sharding Patterns

MongoDB has become one of the most popular NoSQL databases for modern applications requiring flexible schemas and horizontal scalability. As your application grows, understanding MongoDB’s sharding architecture and scaling patterns becomes crucial for maintaining performance. This comprehensive guide explores MongoDB scaling strategies from single servers to globally distributed clusters.

Understanding MongoDB Architecture

MongoDB uses a document-oriented data model where data is stored in flexible, JSON-like documents (BSON format). Unlike traditional relational databases, MongoDB can scale horizontally through sharding, distributing data across multiple servers^[1].
