CNM Cloud Next

The CNM Next Server (previously known as CNM Lab Server; hereinafter, the Server) is a compute server that is used for learning and testing. While being a part of CNM Servers, the Server utilizes one DigitalOcean droplet, which is located at the 167.71.244.79 IP address, and shall support all the applications installed at the Fellow Server and, in addition, one Humhub and one Tiki Wiki CMS Groupware instances.

Platform

The Server is set up as a Digitalocean droplet with dedicated 1 vCPU and 2GB / 50GB Disk in its NYC3 datacenter (New York). The dedicated resources can be increased when the existing ones can no longer support all the services that the Server is expected to provide.

OS

Ubuntu 18.04.3 (LTS) x64

DNS records

All the Server's hostnames shall be fully qualified domain names (FQDNs). The following records shall be associated with the Server:

This list is way far from completion and needs to be further developed.

Control panel

An instance of Vesta Control Panel is installed in order to manage all the services through a web browser. The panel allows for creating users, email addresses, databases, adding domains, setup cronjob, or restart any service.

Backups

The backup policy shall be created in order to setup daily, weekly, and/or monthly backups.

Applications

Any CNM app shall comply with the CNM software requirements.

Certware

One testing instance of CNM Certware shall be run on the Server and to be located at https://cert.next.friendsofcnm.org in the World Wide Web. The instance shall be based on Moodle software and shall duplicate the production instance located at https://cert.friendsofcnm.org

Labware

One testing instance of CNM Labware shall be run on the Server and to be located at https://lab.next.friendsofcnm.org in the World Wide Web. The instance shall be based on a combination of Redmine and SVN software, linked to Bitbucket's file storage, and shall duplicate the production instance located at https://lab.friendsofcnm.org

Linkupware

One testing instance of CNM Linkupware shall be run on the Server and to be located at https://linkup.next.friendsofcnm.org in the World Wide Web. The instance shall be based on SuiteCRM software and shall duplicate the production instance located at https://linkup.friendsofcnm.org

Mailware

One testing instance of CNM Mailware shall be run on the Server and to be located at https://mail.next.friendsofcnm.org in the World Wide Web. The instance shall be based on Roundcube software and shall duplicate the production instance located at https://mail.friendsofcnm.org

Pageware

One testing instance of CNM Pageware shall be run on the Server and to be located at https://page.next.friendsofcnm.org in the World Wide Web. The instance shall be based on WordPress software and shall duplicate the production instance located at https://page.friendsofcnm.org

Videoware

Server provisioning

Mail servers

Two mail servers are designed to receive and send emails. A Postfix instance shall communicate with mail exchangers and a Dovecot instance shall communicate with email clients.

Databases used in the Server

CNM app	DBMS	Size (tables)
Certware	MariaDB
Labware
Linkupware
Mailware
Pageware
Videoware
Wikiware

PostgreSQL and MongoDB may also be considered for further applications.

SSL certificates

All domains are provisioned with Let's Encrypt SSL certificates.
