Scaling applications and environments effectively requires a dual approach that combines performance engineering with resilience, underscoring the importance of Chaos Engineering. While performance engineering ensures systems can handle increased user loads, it often does so under ideal conditions that don't account for real-world challenges, such as infrastructure outages. The analogy of the Burj Khalifa illustrates that a system's ability to scale is incomplete without ensuring reliability and resilience. Gremlin advocates for integrating Chaos Engineering to address these challenges proactively, suggesting that this combination empowers enterprises to reduce incidents, increase availability, and maintain robust systems that delight end-users. By merging these approaches, companies can not only scale efficiently but also ensure that their systems remain operational under adverse conditions.
