### Overview

*TODO: Briefly describe the approach to scalability. Rank your
scalability goals for this design.*

### Relevant parameters

| Parameter           | Description                                                                             |
|---------------------|-----------------------------------------------------------------------------------------|
| ::registered\_users | ::Number of registered users in the database.                                           |
| ::concurrent\_users | ::Number of users logged into the system at a given time.                               |
| ::map\_size         | ::Number of game squares in the playing area. E.g., a 10 x 25 map would be 250 squares. |
| ::game\_pieces      | ::Number of game pieces on the playing area at a given time.                            |

### Scalability Mechanisms

### Performance Goals and Estimates

| Action         | Goal         | Time Formula                  | Description                                                                 |
|----------------|--------------|-------------------------------|-----------------------------------------------------------------------------|
| ::login        | ::1 second   | ::O(Log(registered\_users))   | ::Time that it takes to look up a user by their login name in the database. |
| ::display\_map | ::1/5 second | ::O(map\_size + game\_pieces) | ::Time that it takes to redraw the game map and all game pieces.            |

### System Scalability Checklist

How well do these mechanisms support the achievement of your goals?

::2-4 SENTENCES

#### Have these scalability mechanisms been communicated to the development team and other stakeholders?

::Yes, everyone understands. Feedback is welcome.

::No, this is a risk that is noted in the 
[Risk Management](Project-Plan#Risk-Management) section.
