Mongodb atlas vs mongodb aws

The following tables provide a comparison of MongoDB Community Server and MongoDB Atlas Enterprise features.

DocumentDB and MongoDBArchitectureCompatibilityPerformanceDeploymentDeveloperOperationsPricing

Amazon DocumentDB instance pricing is more expensive than MongoDB Atlas, the fully managed MongoDB service. AWS DocumentDB starts at $200 per month for a single instance, with no free tier. Pricing is per instance-hour consumed, from the time an instance is launched until it is stopped or deleted. Partial instance hours are billed in one-second increments, but there is a 10-minute minimum charge following a billable status change such as creating, modifying, or deleting an instance.

Compare this with MongoDB Atlas, which has a perpetual free tier and starts at $9/mo for shared clusters, and around $60/mo for dedicated clusters.

The pricing comparison below is based on a default 3-node DocumentDB and MongoDB Atlas cluster, with backup storage equal to cluster storage. MongoDB Atlas is 8% to 19% less expensive.

Convenience of a Single AWS Bill

MongoDB Atlas is available via the AWS Marketplace, providing streamlined procurement along with all other AWS services. Buying Atlas through the Marketplace enables customers to benefit from:

• Consolidated billing through their AWS account

• Retirement of their Amazon Enterprise Discount Program commitment

• Simplified procurement with just a few clicks

• Integration with AWS Marketplace catalogs and reports

• A designated advisor from the AWS Marketplace team

What is DocumentDB?

Amazon DocumentDB is a NoSQL JSON document database service with a limited degree of compatibility with MongoDB.

DocumentDB is not based on the MongoDB server. Rather it emulates the MongoDB API, and runs on top of Amazon’s Aurora backend platform. This creates significant architectural constraints, functionality limitations and broken compatibility.

DocumentDB claims to support the MongoDB 4.0 API, which implies that it is at parity with MongoDB v4.0, released back in June 2018. In actual fact, the DocumentDB 4.0 feature set more closely resembles MongoDB 3.0 and 3.2, released in 2015. In addition, compatibility testing reveals it fails over 64% of the MongoDB API correctness tests. Applications written for MongoDB will need to be re-written to work with Amazon DocumentDB.

The key differences between DocumentDB and MongoDB’s on-demand, elastic, and fully managed Atlas service are summarized below.

What is MongoDB Atlas?

MongoDB offers the fully managed, on-demand and global MongoDB Atlas service, in the public cloud. Atlas enables customers to deploy, operate, and scale MongoDB databases on AWS, Azure, or Google Cloud. MongoDB Atlas is available through a pay-as-you-go model and billed on an hourly basis. It’s easy to get started – use a simple GUI or programmatic API calls to select the public cloud provider, region, instance size, and features you need. MongoDB Atlas provides:

• Automated database and infrastructure provisioning along with auto-scaling so teams can get the database resources they need, when they need them, and can elastically scale in response to application demands.

• Security features to protect your data, with network isolation, fine-grained access control, auditing, and end-to-end encryption down to the level of individual fields. enabling you to comply with regulations such as ISO, HIPAA and GDPR. Built in replication both within and across regions for always-on availability.

• Global Clusters for a fully managed, globally distributed database that provides low latency, responsive reads and writes to users anywhere, with strong data placement controls for regulatory compliance.

• Combined transactional and analytical capabilities with Atlas Analytics Nodes to isolate analytics queries from operational workloads while providing real-time insight. Native MongoDB analytics tools, such as MongoDB Charts and MongoDB Connectors (for SQL, Tableau and Spark) are configured to utilize Analytics Nodes by default.

• Fully integrated native MongoDB data visualization tools – MongoDB Charts, which supports the full richness of the document model, including nested, hierarchical and geospatial data and provide embedding and sharing capabilities. Quickly build visualizations of your data without needing to deploy or manage any software or infrastructure.

• Fully integrated MongoDB Atlas Data Lake which allows you to quickly and easily query data in any format on Amazon S3 using the MongoDB Query Language (MQL) and tools and get value from your data faster.

• Fully managed backups with point in time recovery to protect against data corruption, and the ability to query backups in-place without full restores.

• Fine-grained monitoring and customizable alerts for comprehensive performance visibility. Automated patching and single-click upgrades for new major versions of the database, enabling you to take advantage of the latest MongoDB features.

• Access to the Atlas App Services, with Data Access Controls, Functions, and Triggers delivered in a completely serverless model.

• Native time-series support optimized for both highly performant data ingestion and querying, along with reduced I/O and storage overhead

• The full text Atlas Search service providing rich search capabilities against your fully managed databases with no additional infrastructure or systems to provision, manage, or scale.

• Live migration to move your self-managed MongoDB clusters into the Atlas service or to move Atlas clusters between cloud providers.

• Stable API to make upgrades risk-free, future-proofing your development

• Widespread coverage on the major cloud platforms with availability in ~100 cloud regions across Amazon Web Services, Microsoft Azure, and Google Cloud. MongoDB Atlas delivers a consistent experience across each of the cloud platforms, ensuring developers can deploy wherever they need to, without compromising critical functionality or risking lock-in.

MongoDB Atlas is serving a vast range of workloads for startups, Fortune 500 companies, and government agencies, including mission-critical applications handling highly sensitive data in regulated industries. The developer experience across MongoDB Atlas and self-managed MongoDB is consistent, ensuring that you easily move from on-premises to the public cloud, and between providers as your needs evolve.

Beyond the database, the MongoDB Atlas Data Lake allows you to quickly and easily query data in any format on Amazon S3 using the MongoDB Query Language (MQL) and tools. You can spin up your data lake right alongside your Atlas OLTP clusters from a common UI. With Atlas Data Lake you can realize the value of your data lake faster: you don’t have to move data anywhere, you can work with complex data immediately in its native form, and with its fully-managed, serverless architecture, you control costs and remove the operational burden. DocumentDB offers no equivalent capability, and so users must spin up an entirely separate service with a different query language to access S3 data.

Built and run by the same team that develops the data platform, MongoDB Atlas is the best way to run MongoDB apps.
