Document Database Service (DDS)

Keep a handle on complex files

In addition to relational databases, NoSQL databases can also be used for the structured storage of documents. MongoDB is one example of a document-oriented NoSQL database. The minimum configuration of a Document Database Cluster instance consists of two Mongo nodes which acts as a central distribution point for data read and write commands, a config node that saves the settings of the database instances and at least two shards (per database instance) for data storage. A replica set consists of three nodes: primary, secondary, and hidden. The three-node architecture is automatically set up, and the three nodes synchronize data with each other automatically to ensure data reliability.

MongoDB can distribute queries to multiple servers, thus offering better response times than SQL databases. The lack of a predefined structure for database entries facilitates agile development projects. Document databases are ideal for managing files that go beyond simple numbers or words.

Document Database Service in the Open Telekom Cloud

The Document Database Service is based on MongoDB. The minimum configuration of a Document Database cluster instance consists of two Mongo nodes, two shard nodes and one Config node. The shard cluster can contain up to 12 shards. General purpose flavors (vCPU : GB RAM ratio 1:4) with up to 16 vCPUs are used. The service can be scaled and makes it possible to save objects quickly and in a structured manner. Because replicas are automatically created with this type of database, the service offers a high level of performance and availability. Furthermore, performance and availability can be increased by adding further replicas. MongoDBs can be encrypted.
