Storage Facility
The storage facility of the horizontal cluster is a shared NoSQL database cluster that stores configuration data, events, and binary blocks of all primary nodes. The central idea behind this storage facility is that mirgation of resources between primary nodes doesn’t cause relocation of their persistent configuration and events.
Functions of the storage level include:
Storing configuration data: The storage facility keeps configurations of all resources that are operating on the primary nodes.
Storing events: The storage facility captures and keeps events generated during the operation of resources on the primary nodes.
Storing binary data: The storage facility saves binary data associated with resources on the primary nodes.
Providing necessary performance: The storage facility is designed to provide the required performance to support an extremely large number of devices and process data coming from these devices efficiently.
Server-agnostic storage: Data in the storage facility is seamlessly shared between all primary nodes and remains intact while resources migrate across the cluster.
