Database as a Service

This service is actually a relational database management system (PostgreSQL) used for secure storage and retrieval of web app data. It supports a variety of data types (for example, XML, JSON, arrays, geometry, and so on) and can easily cope with managing data from both single-machine apps and applications with many concurrent users.

Database as a Service ensures management of database instances, automatically creating their synchronous replicas in case of a crash. This ensures high availability of stored relational data without user intervention or the need to change the configuration of an app.

The service offers the following features:

  • High availability and fault tolerance with automatic point-in-time recovery (PITR) to any moment within the preceding seven-day period
  • Enhanced data security due to encryption at rest
  • Automatically applied patches and updates to address data loss and security issues
