Data within CNM Farms (hereinafter, the Lectio) is the lesson part of the CNM Farm 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 predecessor lectio is Databases of CNM Cloud.
Key terms
- CNM Farms. The combination of computing servers that host CNM Cloud, as well as those parts of the cloud that are provisioned to run serverless systems.
- WorldOpp Federated Farm. The computing server that hosts the software applications that WorldOpp Middleware powers. The CNM Cloud Next is one of the CNM Farms.
- CNM Cloud Next. The computing server that hosts those non-federated end-user applications of CNM Cyber that the CNM Cyber Team administers. The Server is located at the 167.71.244.79 IP address. The CNM Cloud Next are ones of the CNM Farms. Another server, the CNM EndUser Farm, hosts the set of CNM apps that is identical to CNM Cloud Next' set.
- CNM HandsOn Farm. The computing server of CNM Farms that the CNM Cyber Team administers.
- CNM EndUser Farm. The computing server that hosts those non-federated end-user applications of CNM Cyber that the WorldOpp Fellow Staff administers. The Server is located at the 159.89.230.212 IP address. The CNM EndUser Farm is one of the CNM Farms. Another server, the CNM Cloud Next, host the set of CNM apps that is identical to Fellow Server's set. The difference is that Fellow Server's apps are used for career services, while Next Server's ones are used for hands-on training.
Script
- Every software system of CNM Cloud is supported by its own relational database management system (RDBMS).
- WorldOpp Middleware collects most important data from various systems throughout the CNM Farms, transforms the collected data in a unified format, and stores the data in its NoSQL database. The CNM Cyber Team decides on what data shall be collected, transformed, and stored.
- To secure data from disasters such as computer failures and other data loss events, all the data is backed up at the same time every day. At CNM Cloud, that means that the database data is copied and stored separately from the computing server on which the database is installed. In that way, the data backup wouldn't be destroyed if one server collapses.
- For different systems, the backup policies may vary, but the backup system always contains several copies of all data that the CNM Cyber Team considers worth saving. For instance, the system may contain backups that were made yesterday, a day before yesterday, last week, and last month. Commonly, one "old" backup is deleted when one new backup is made.
- As a disaster recovery, any data copy can substitute the original data in the database. However, no data backup cannot restore the data that have been created after the backup was made.
- Data of CNM Cloud Next, which is used for experiments, is periodically destroyed. Data of CNM HandsOn Farm, which support hands-on training, is destroyed upon one's course completion.
Clusters in CNM Farms is the successor lectio.
