Compare container vs VM overhead. Containers share the host kernel (10–50 MB overhead); VMs run full OS (1–2 GB RAM, 30–60 s boot time). Container density is typically 5–10× higher.
Enter the values for the scenario you are assessing. Compare container vs VM overhead. Containers share the host kernel (10–50 MB overhead); VMs run full OS (1–2 GB RAM, 30–60 s boot time). Container density is typically 5–10× higher. Use the container vs vm overhead result to inform your calculation.
