Test Case

• Performance - Throughput per x vCPU y GiB Memory - CPU/Memory/Disk/Network Overhead
• Stability - TP95 latency - TP99 latency - Lowest/Highest latency
• Robustness - Container Failure - Pod Failure - Node Failure - Network Failure - Disk Failure
• Scalability - Vertical - Horizontal - No Traffic Failure during scaling - Scale Up Duration
• Overload - System not crash
