Information about supported regions, MongoDB versions, types, hardware resources, storage management, disk type, backup policies, logs and metrics, and users for Galaxy Databases.


Supported Regions


The Galaxy Databases offer is available in the following regions:


  • VIR (Virginia, USA)
  • FRA (Frankfurt, Germany)
  • SYD (Sydney, Australia)


MongoDB Versions


The Galaxy Databases offer supports the following MongoDB versions:


  • MongoDB 4.0.19
  • MongoDB 4.2.23
  • MongoDB 4.4.17
  • MongoDB 5.0.14
  • MongoDB 6.0.5
  • MongoDB 7.0.4
  • MongoDB 8.0.4


Types


  • Standalone: A single instance of MongoDB that operates independently.
  • ReplicaSet: A set of MongoDB instances that offers high availability and data replication.


If you need Oplog support (for example, for Meteor.js apps), you must request a Replica Set MongoDB. Standalone MongoDB instances do not support Oplog.

Storage Management


The disk size indicated above represents the total disk capacity of the underlying machine. However, a portion of this capacity is allocated for the operating system installation.


We make concerted efforts to prevent "disk full" scenarios that could jeopardize the health of the cluster. Therefore, the customer will:


  • Receive an initial email alert when the cluster's storage capacity reaches 80%.
  • Receive a subsequent email alert when the cluster's storage capacity reaches 90%.
  • Experience their database instance being transitioned into "read-only" mode once the storage capacity reaches its limit. In this mode, no further write operations can be performed.


Disk Type


Here in Galaxy Databases, we use SSD NVMe drives, which are high-performance solid-state drives optimized for rapid data access. They offer low latency and high transfer speeds, making them ideal for applications requiring superior performance.


Backup Policies


Please see our article: Database backup details


Users


To effectively manage your MongoDB cluster, the Galaxy Database team sets up several MongoDB users within your clusters:


  • admin@admin: This is your initial user with administrative privileges.
  • galaxyadmin@admin: This is a technical user required for automation purposes.
  • galaxybackup@admin: This user is designated for performing backups.
  • galaxymonitor@admin: This user is also used for monitoring.
