Amazon Web Services (AWS), an Amazon.com company, announced Amazon DocumentDB (with MongoDB compatibility), a fast, scalable, highly available, and fully managed document database service that supports MongoDB workloads.
Developers can use the same MongoDB application code, drivers, and tools as they do today to run, manage, and scale workloads on Amazon DocumentDB and enjoy improved performance, scalability, and availability without having to worry about managing the underlying infrastructure.
Customers can easily migrate their on-premises or Amazon Elastic Compute Cloud (EC2) MongoDB databases to Amazon DocumentDB with virtually no downtime using the AWS Database Migration Service (DMS). There are no up-front investments required to use Amazon DocumentDB, and customers only pay for the capacity they use.
AWS customers use MongoDB as a document database to store, retrieve, and manage semi-structured data. Customers like using the MongoDB Application Programming Interface (API) and expressive language query to help them quickly build and evolve applications, but they often only take advantage of a fraction of the functionality the API offers.
Customers also find it challenging to build performant, highly available applications on MongoDB that can quickly scale to multiple Terabytes (TBs) and hundreds of thousands of reads and writes-per-second because of the complexity that comes with setting up and managing MongoDB clusters.
As a result, customers spend a lot of time and expense managing MongoDB clusters at scale, including dealing with the undifferentiated heavy lifting of securing, patching, and operating MongoDB. Just like on-premises deployments, managed MongoDB systems face data replication challenges and they suffer from long recovery times in the event of failure. As a result, customers are struggling to get the performance, scalability, and availability their growing applications need over time.
Amazon DocumentDB is designed from the ground up to give customers the performance, scalability, and availability they need when operating mission-critical MongoDB workloads at scale. Amazon DocumentDB implements the Apache 2.0 open source MongoDB 3.6 API by emulating the responses that a MongoDB client expects from a MongoDB server, allowing customers to use their existing MongoDB drivers and tools with Amazon DocumentDB.
Amazon DocumentDB uses a unique, distributed, fault-tolerant, self-healing storage system that automatically scales up to 64 TB of data per cluster, so customers can save time and money by not having to worry about capacity planning or over provisioning storage infrastructure. Amazon DocumentDB reduces database I/O by writing only database changes to the storage layer, avoiding slow, inefficient, and expensive data replication across network links.
