AWS LAUNCHES FULLY-MANAGED DOCUMENT DATABASE SERVICE
Amazon Web Services (AWS) has announced a fully-managed document database service, building the Amazon DocumentDB (with MongoDB compatibility) to support existing MongoDB workloads. The cloud giant said developers can use the same MongoDB application code, drivers, and tools as they currently do to run, manage, and scale workloads on Amazon DocumentDB.Amazon DocumentDB uses an SSD-based storage layer, with 6x replication across three separate Availability Zones. This means that Amazon DocumentDB can failover from a primary to a replica within 30 seconds, and supports MongoDB replica set emulation so applications can handle failover quickly. Each MongoDB database contains a set of collections -- similar to a relational database table -- with each collection containing a set of documents in BSON format.Amazon DocumentDB is compatible with version 3.6 of MongoDB and storage can be scaled from 10 GB up to 64 TB in increments of 10 GB.
