DatastoreA deployment of a Database on CCX. A Datastore has a unique ID, it is essential to include this when contacting Support with issues or queries.ServiceDeployment
NodeA Virtual Machine (VM) in a Cloud that makes up a Datastore. A Node consists of:
- CPU - the number of cores

- RAM - the amount (GB) of memory

- Storage - the amount (GB/TB) of persistent storage
Virtual Machine (VM)
Node
Server
Instance
Compute
StorageThe amount of persistent data for your Datastore.
Storage comes in multiple different formats and not all are supported by all Clouds. There are cost and performance considerations when choosing the storage.
Storage
VolumesThe types of Storage available. Typically, this is measured in IOPS and the higher IOPS has increased performance with an increased cost per GB
DatabaseThe engine deployed and configured for your Datastore. To see these options, check Supported DatabasesDatabase Management System (DBMS)General
Virtual Private Cloud (VPC)A private network configured that is unique to your account and ensures that any traffic between your Datastore does not go over the Public InternetPrivate NetworkNetworking
CloudAn infrastructure provider where Datastores can be deployedDeployment
RegionA geographic region with one or more Datacentres owned or operated by a Cloud. A Datastore is deployed into a single RegionDeployment
Availability Zone (AZ)A Region can have one or more Availability Zones. More than one Availability Zones allows one Datacentre to go down without bringing down all of the Nodes in your Datastore.
CCX will automatically attempt to deploy each Node in a Datastore into a different AZ (if the Region supports it)
Deployment
ReplicationA method of exchanging data between two Nodes that ensures they stay in sync and allows one Node to fail without bringing your Datastore downOperations
Primary / ReplicaThe recommended deployment for a Production Datastore with 2 or more Nodes, one acting as the Primary and the other(s) acting as the ReplicaHighly Available
High Availability
Operations
Multi-PrimaryMultiple Nodes deployed with the same role, all of them acting as the Primary. This topology is not supported by all DatabasesClusteredOperations
StatusThe last known status of your Datastore. For details of the possible statuses, see hereStateOperations
MaintenanceThe application of critical security updates to your Datastore. These are applied in your Maintenance Window which can be configured per Datastore.Operations
MonitoringThis is the metrics of the hardware and software for your Datastore. These can be accessed in the CCX Dashboard and can be shown per Node. For details of the metrics available, see here.Observability
