# Description:

# Every iteration we'll increase the number of concurrent users by 50
|
|
# Each iteration adds an aditional 5 minutes (300s)
|
|
# So after 75 minutes we'll reach our final iteration
|
|
# Which will then run for 30mins and will push through 300 concurrent requests a second over that period
|
|
# So on the last iteration we'll hit the service 540,000 times over the last 30 minutes period (300*1800)
