Container Capacity Calculation

Given

• Expected Traffic = 15,000 requests/second
• One container capacity = 500 requests/second
• Required headroom = 30%

---

Step 1

Number of containers without headroom

15000 / 500 = 30 Containers

---

Step 2

Adding 30% reserve capacity

30 × 1.30 = 39 Containers

---

Final Result

The application should run 39 containers to safely handle the expected traffic while maintaining additional capacity for sudden traffic spikes and infrastructure failures.
