Very often, I heard that chaos engineering is only a technique used by larger companies (like Netflix) or in cloud native environments. You want to know if chaos engineering is only usable in cloud native environments. With the rise of cloud and container technologies, companies developed a lot of microservices. Dynatrace news.

Cloud provider hypervisor changes (for cloud guests) 1. Plotting the percent performance loss vs syscall rate per CPU, for my microbenchmark: Applications that have high syscall rates include proxies, databases, and others that do lots of tiny I/O. They are: 1. Guest kernel KPTI patches (this post) 1. Linux 4.14.12-virtual
