Cosmos DB vs. MongoDB vs. MongoDB Atlas: which is the best choice for storing document-oriented data?

At some point, transitioning to a non-relational database becomes inevitable for any modern business aiming to efficiently handle ever-growing streams of relevant data. Join our seasoned in-house expert, Eugene Kileiko, as he explores three popular NoSQL tools for storing document-oriented data—Azure Cosmos DB, MongoDB, and MongoDB Atlas.

    During my tenure as a tech specialist, I have often faced the dilemma of choosing the right NoSQL document-oriented database for an upcoming project from a plethora of options available. Given my experience, I know how daunting and time-consuming the entire process can be. To facilitate decision-making when it comes to selecting a suitable service for data storage, I have compiled this concise yet informative guide, providing a comprehensive comparison of Cosmos DB, MongoDB, and MongoDB Atlas.

    Azure Cosmos DB vs. MongoDB vs. MongoDB Atlas: final verdict

    After careful consideration, I have drawn the following conclusions:

    • Cosmos DB is the ideal choice for apps that require high availability, scalability, seamless performance, and minimized latency across global regions. Additionally, this same database is the optimal choice for developers who need a fully managed service within the Azure ecosystem.
    • MongoDB is a perfect fit if you need either an open-source or self-managed solution with consistent performance in regions close to your user base.
    • MongoDB Atlas is a viable option if you want a solution that is fully administered by the service provider, avoids vendor lock-in, and offers high availability, scalability, enhanced security, and optimal performance with reduced latency across the globe.

    All the same, the final choice depends on your specific demands, priorities, and budget considerations.

    F.A.Q. about Cosmos DB, MongoDB, and MongoDB Atlas

    • Cosmos DB is a fully managed NoSQL database distinguished by features, such as turnkey data distribution, support for multiple data models, high availability, scalability, low latency, and seamless performance.

    • MongoDB is a self-hosted non-relational database renowned for its flexible document schema, high availability, and strong performance in designated regions. MongoDB Atlas, in turn, is a fully managed cloud database service that extends the capabilities of MongoDB, offering global distribution, improved scalability, and advanced security features.

    • MongoDB Atlas vs. MongoDB vs. Cosmos DB pricing depends on several key factors, including the deployment method, throughput, storage capacity, data transfer, and more.

      • Use Cosmos DB if you work within the Microsoft Azure ecosystem and prioritize high availability, scalability, seamless performance, and minimized latency globally.
      • Opt for MongoDB if you want a free solution (MongoDB Community Server) or a self-hosted paid database (MongoDB Enterprise Advanced) with consistent performance in specific regions.
      • Choose MongoDB Atlas if you need high availability, scalability, and optimal performance with low latency worldwide and want to avoid vendor lock-in.
