Hostname | Description | Naming Convention |
---|---|---|
S1 | Host system for Registration System. | Use a 2-3 letter convention to describe the host's main function. As the purpose of the host can easily change we use a generic name, S1 for system 1. |
RGH1V00WEB | Runs Apache Web Server. | RG = Registration = Overarching Project Code |
RGH1V00APP | Runs Tomcat Application Server and HypSQL Database Server. | This has both an application and database. Because the database is portable and more easier to move, we make the judgment call to name the system APP after the more primary , less likely to move, long term function of the server. The convention follows but notice the V00. 00 = First virtual server for the specified function and it visually and via sorting will correspond to the places this server with the correspond Web Server. |

At this point the hostnames are not too bad. Their real value comes when the system needs to grow.
The system grows and requires a second application server to manage the load. As in many cases, the application is the bottle neckUsually new applications are added first as they generate the most load. Here is how it will look in a sorted list,
Hostname | Description | Naming Convention |
S1 | Host system for Registration System. | Existing. |
RGH1V00WEB | Runs Apache Web Server. | Existing. |
RGH1V00APP | Runs Tomcat Application Server and HypSQL Database Server. | Existing. |
RGH1V01APP | Runs Tomcat Application Server. | The first 0 in MGH1V00APP shows that the server is related to the Web Server RGH1V00WEB |
The convention naturally sorts well. Now let's add something new to the mix.

There is need for a new system for migrating users to tokens which we'll call MG for migration. Notice that we use a generic name rather than TM as the system could evolved evolve to do other types of migrations. The system is low budget and considered temporary. As such, the customer wants to reuse the web serverserver RGH1V00WEB.
Hostname | Description | Naming Convention |
S1 | Host system for Registration System. | Existing. |
RGH1V00WEB | Runs Apache Web Server. | Existing |
RGH1V00APP | Runs Tomcat Application Server and HypSQL Database Server. | Existing |
RGH1V01APP | Runs Tomcat Application Server. | Existing |
MGH1V00APP | Runs Tomcat Application Server and HypSQL Database Server. | Again the V0 first 0 in MGH1V00APP clearly shows that it is connected to RGH1V00WEB and the MG indicates the systems primary function is for migrations. |
Phase 4
Over time the system becomes more critical and has grown in number of users. The agrees to buy new hardware, introduce a load balancer and a second web and application server. Also, as with many systems the temporary TM system becomes permanent.
