Structure of CNM Cloud

CNM Cyber

Structure of CNM Cloud (hereinafter, the Lectio) is the lesson part of the CNM Cloud Essentials lesson that introduces its participants to CNM Cloud. This lesson belongs to the Introduction to CNM Cloud session of the CNM Cyber Orientation.

Content

The successor predecessor lectio is CNM App Groups.

Script

CNM apps are most visible parts of CNM Cloud, but it is more than just those end-user applications. The apps do not exist without their environment. At CNM Cloud, this environment consists of CNM Cloud Foundation and WorldOpp Middleware.

Using its operating systems, web servers, database management systems, and support for programming languages, the Foundation provides functionality for both the apps and the Middleware. All CNM apps are hosted either by a computing server or, if the app is serverless, directly by the specially-provisioned cloud.

The Middleware provides CNM apps with those services that are central for the Cloud and cannot be provided by the Foundation. Probably, we can describe these services as software glue between CNM apps and the Foundation. Particularly, the Middleware handles user permissions and rights throughout the whole Cloud.

To make CNM Cloud stable, all of its software systems are run in clusters. Each cluster includes two or more exactly the same systems. If one of them fails or is not available, another would continue running. This feature of the Cloud's structure is called redundancy.

Special load balancers make sure that all the parts of the cloud work synchronously to cover for each other and the Cloud users access the right part of the structure.

What the Foundation Is is the successor lectio.
