Types of Chaos Experiments: Simulating Real-World Challenges

Picture having a toolbox of tools to test how well your application can handle challenges. That’s what chaos experiments are! Azure Chaos Studio offers types of experiments, each simulating real-world scenarios your application may face:

• Fault Injection: This experiment introduces “faults” in your system, such as mimicking a server crash, an entire disk, or network disruption. It allows you to pinpoint any vulnerabilities by observing how your application responds to these simulated failures. Now you can utilize your wisdom to enhance the ability of that system to recover smoothly.
• Latency Injection: Picture your application during peak traffic hours – things might slow down. Latency injection experiments simulate this by introducing delays in network communication. This lets you see how well your app works under pressure and find any areas that need to be optimized.
• Resource Exhaustion: What happens if your app runs out of memory or CPU power? Running experiments on resource exhaustion helps simulate these situations, letting you test how well your app handles resources and implements scaling solutions.
