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 134.209.40.232 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 18.04.2 x64
DNS records
- The following records shall be associated with the Server:
Record Hostname Value TTL (seconds) A next.friendsofcnm.org directs to 134.209.40.232 3600 A video.next.friendsofcnm.org directs to 134.209.40.232 3600 A lab.next.friendsofcnm.org directs to 134.209.40.232 3600 A cert.next.friendsofcnm.org directs to 134.209.40.232 3600 A wiki.next.friendsofcnm.org directs to 134.209.40.232 3600 A mail.next.friendsofcnm.org directs to 134.209.40.232 3600 A net.next.friendsofcnm.org directs to 134.209.40.232 3600 A linkup.next.friendsofcnm.org directs to 134.209.40.232 3600 CNAME www.next.friendsofcnm.org is an alias of next.friendsofcnm.org. 43200 NS friendsofcnm.org directs to ns1.digitalocean.com. 1800 NS friendsofcnm.org directs to ns2.digitalocean.com. 1800 NS friendsofcnm.org directs to ns3.digitalocean.com. 1800
- This list is way far from completion and needs to be further developed.
Applications
Certware
- One 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 is based on Moodle software and shall duplicate the production instance located at https://cert.friendsofcnm.org
Labware
- One instance of CNM Labware (Redmine and SVN linked to Bitbucket's file storage; to be located at https://lab.next.friendsofcnm.org).
Linkupware
- One instance of CNM Linkupware (SuiteCRM; to be located at https://linkup.next.friendsofcnm.org).
Mailware
- One instance of CNM Mailware (Roundcube; to be located at https://mail.next.friendsofcnm.org).
Pageware
- Several instances of CNM Pageware (WordPress; to be located at https://page.next.friendsofcnm.org).
Videoware
- One instance of CNM Videoware (YouPHPTube; to be located at https://video.next.friendsofcnm.org).
Wikiware
- Two instances of CNM Wikiware setup for two languages (MediaWiki; to be located at https://wiki.next.friendsofcnm.org). In addition, one instance of Tiki Wiki CMS Groupware shall be installed for testing purposes.
Server provisioning
Mail servers
- A fully qualified domain name (FQDN) shall be used for configuring the host. Postfix is the mail transfer agent which is responsible software for delivering and receiving emails.
Web servers
- Two web servers are designed to satisfy requests of World Wide Web clients. Nginx shall be placed in front of Apache HTTP Server. Nginx shall be used as a reverse proxy, load balancer, mail proxy and HTTP cache.
FTP servers
- A Very Secure File Transfer Protocol Daemon (vsFTPd) shall be used for secure file transfers.
Databases
- No standalone database server is planned. Separate database management systems, which are based on MariaDB instances, shall serve separate applications as follows:
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.
