Term	Definition	AKA	Area
Datastore	A 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.	Service	Deployment
Node	A 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
Storage	The 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
Volumes	The types of Storage available. Typically, this is measured in IOPS and the higher IOPS has increased performance with an increased cost per GB
Database	The engine deployed and configured for your Datastore. To see these options, check Supported Databases	Database 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 Internet	Private Network	Networking
Cloud	An infrastructure provider where Datastores can be deployed		Deployment
Region	A geographic region with one or more Datacentres owned or operated by a Cloud. A Datastore is deployed into a single Region		Deployment
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
Replication	A method of exchanging data between two Nodes that ensures they stay in sync and allows one Node to fail without bringing your Datastore down		Operations
Primary / Replica	The recommended deployment for a Production Datastore with 2 or more Nodes, one acting as the Primary and the other(s) acting as the Replica	Highly Available High Availability	Operations
Multi-Primary	Multiple Nodes deployed with the same role, all of them acting as the Primary. This topology is not supported by all Databases	Clustered	Operations
Status	The last known status of your Datastore. For details of the possible statuses, see here	State	Operations
Maintenance	The application of critical security updates to your Datastore. These are applied in your Maintenance Window which can be configured per Datastore.		Operations
Monitoring	This 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
