CNM Lab Farm (formerly known as Cloud Next; hereinafter, #The Farm) is the segment of Opplet that is responsible for providing users with all of end-user applications that are used for experiments. #The Farm requires no high availability functionality; however, it features advanced backup and recovery systems.

CNMCyber Team (hereinafter, #The Team) develops and administers #The Farm. To sustain #The Farm online, #The Team rents Lab Infrastructure.


Features

DNS entry point

load balancer on a public web address

Syncronization

synchronization of resources of common individual nodes, at least databases.

Monitoring

Security

including firewalls

Backup and recovery

DNS zone

To locate #The Farm's public resources in the Internet, the following DNS records are created in #The Farm's DNS zone:
Field Type Data Comment (not a part of the records)
pm3.bskol.com AAAA record 2a01:4f8:10b:cdb::2 Node 3

(hereinafter, the Next) is the part of Opplet that is dedicated to technological research and development (R&D) undertaken to discover and shape the future of Opplet.

While being a part of CNM Farms, the Server utilizes one DigitalOcean droplet, which is located at the 167.71.244.79 IP address, and shall support all the applications that are installed at the CNM Next Farm. In other words, the Server can be described as a learning and testing variant of the CNM Bureau Farm.

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; kernel configs are setup to speed up servers and avoid limitations.

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.
The control panel is enhanced with a Softaculous installation, which allows for automatic installation of popular commercial and open-source end-user applications to the Server. Its scripts are executed from the panel's administration area.

DNS records

All the Server's hostnames shall be fully qualified domain names (FQDNs). The records shall be validated with https://intodns.com/

Server provisioning

Mail servers

Web servers

Two web servers are designed to satisfy requests of World Wide Web clients. Nginx is placed in front of Apache HTTP Server and tuned shall be used as a reverse proxy, load balancer, mail proxy and HTTP cache. Particularly, Nginx handles static files.

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)
Educaship Moodle MariaDB
Educaship GitLab
Linkupware
Mailware
Educaship WordPress
Educaship Odoo Unknown
Tubeware MariaDB
Educaship MediaWiki
PostgreSQL and MongoDB may also be considered for further applications.

SSL certificates

All domains, including all sub-domains, are provisioned with Let's Encrypt SSL certificates.

Requirements

Requirements to the Server are a part of CNM Cyber requirements.

Business requirements

The Team needs the Server because of the following:
  • Those learners who are a part of the Team shall have opportunities for hands-on training; AND/OR
  • The associates of the Team shall have opportunities for experimenting on CNM apps;
without any fear of disrupting the services of CNMCyber.

Solution requirements

The Server shall be:
  • Located at the same facility and produce the same services as the CNM Bureau Farm;
  • Accessible to:
    1. Use its administrative panel:
      • 24/7 to the Team fellows;
      • 24/7 to those Team associates whom the CNM Technology Board authorizes;
      • When needed, those Team learners who are in their hands-on training;
    2. View its publicly-open pages 24/7 and register to everyone:
  • Easily restored when the Server fails. Those failures may particularly be caused by hands-on training sessions and experiments.

Project requirements

The following requirements are effective with regard to the Server developments:
  • All public data related to requirements to the Server shall be published on CNM Wiki.
  • All private data related to the Server shall be published on CNM Lab.
  • Only the CNM Technology Board can approve changes.

Administration

The Board oversees the Server development and, particularly, approves the Server's requirements. The Friends Of CNM implements the approved requirements.

History

Gary Ihar introduced the idea of the Server in early August of 2019. After MichaelC approved the idea, Gary Ihar started recruitment of the contractor. Some design ideas were proposed by Chris M. In early September, Atif G. was hired as the contractor. By mid-September, he installed the control panel, all its applications, web and mail servers. Atif G. also configured SSL certificates, generated DNS records, and plugged most of the applications into the CNM Fed Farm through LDAP.

To-do list

The Team believes that it is needed to:
  1. Plug all the applications into the federal server through LDAP.
  2. Design the policy of granting access to the Team staffers and learners.
  3. Document all developments using CNM Lab.

Things to be clarified

  • packages updated + upgraded
  • vesta controlpanel has been installed
  • now need to setup its configs
  • vesta control panel detail
  • softaculous also installed with vesta
  • nginx tunning ok
  • mysql tunning ok
  • apache tunning ok
  • security limits config done
  • php configs done

Development

Development of the Farm occurs under the Farm for Lab project.
