The overwhelming majority of the software solutions that CNM Cloud employs are commercial off-the-shelf (COTS). Before being included in CNM Cloud, these applications were already available on the market to be installed and used. What makes COTS solutions attractive?

In most cases, custom coding is more expensive than using pieces of software that have already been created. Even if you are a coder, coding is time-consuming; plus, custom code requires software design, planning, testing, and bug-fixing in addition to coding.

Periodically, the CNM Cyber Team reviews those COTS solutions that are included in CNM Cloud and researches the market. The internal study includes the history of bug tickets and identified troubles. An external research also encounters official websites and professional sources.

If new candidates are identified, they are deployed at CNM Next Server as CNM bulk apps to be tested. The CNM Technology Board can decide to deploy or not to deploy them as a part of CNM core apps. To make the decision, the Board takes into consideration three factors:

1. Review and testing results;
2. The popularity, including the number of installs and the number of contributors; and
3. The job market demands.

If no software solution is available on the market, the Team may decide to custom code it. For instance, the software behind the user management system at WorldOpp Middleware, as well as CNM Cabinware are custom coded using PHP programming language.

Any custom-coded solution that CNM Cloud uses is being constantly updated since its development is a living project.
