? Baseline Slot Commitment
Let:
S = committed slots
P = price per slot-hour
H = hours/month
Monthly Cost = S × P × H
? Required Slot Formula
Let:
W = total slot-seconds workload/month
T = desired runtime window (seconds)
Required Slots ≈ W / T
? Optimal Commitment Strategy
Let:
Peak usage = P_s
Average usage = A_s
Optimal commitment often ≈ 70–80% of P_s
Why?
Autoscaling handles spikes cheaper than full overcommitment.
? Slot Efficiency Metric
Efficiency = Used Slot-ms / Available Slot-ms
Target: 65–85%
< 50% = waste
95% = contention
? Cost per Business Metric
Example:
Cost per 1000 dashboard views =
(Total BI slot cost) / (dashboard views / 1000)
(Total BI slot cost) / (dashboard views / 1000)
Translate infra → business value.
