Architecture¶
The Zadara cloud contains two storage nodes which are assigned the roles of Cloud Controller Master (CCMaster) and Cloud Controller Slave (CCSlave). The CCMaster and CCSlave Storage Nodes (SN) are responsible for Cloud management and monitoring in addition to virtual storage controller hosting, like any other Cloud storage node. The CCMaster storage node actively hosts all cloud management function including a dedicated Cloud Controller Virtual Machine (CCVM). In case of any failure in the Cloud Controller Master, a failover of all cloud management resources to the Cloud Controller Slave is performed.
Zadara cloud can be centrally managed by 2 software components:
Provisioning portal
Command center
By default, both Provisioning portal and Command Center reside within the Cloud Controller Virtual Machine.
Zadara’s Provisioning portal can also be deployed in a centralized location, detached from a single Cloud CCVM. This topology should be deployed when there is a need to manage multiple clouds in multiple regions in a single portal.
Important
Zadara’s web applications allow only TLS 1.2 and higher, which is the recommended TLS level by industry standards. The TLS (Transport Layer Security) protocol secures transmission of data over the internet using standard encryption technology.
