Share Description
In this course, you will learn :
- Chaos engineering is the process of attempting to determine the limits of a system and simulating any adverse effects that may occur.
- These simulations then assist you in determining the best way to improve your system's resilience.
- To demonstrate the importance of scaling, fault tolerance, and high availability, you will first learn how to destroy application instances.
