WCS server participates in the billing if server process is running and license is activated.
One license key can be activated on several WCS servers.
If an 1-hour interval within a month is detected when N servers were used simultaneously, then it will be billed for N * $75 for that month.
If several such intervals are detected within a month then it will be billed according to the interval of maximum usage.
For example, usage of 2 servers was detected on June 15 in 9am to 10am interval, and usage of 3 servers was detected on June 30 from 16pm to 17pm. As the result, it will be billed
for 3 servers for June.
