This document introduces Roman Sevastyanov and provides information about load and stress testing. It defines load testing and stress testing, outlines their goals, and discusses different testing types and tools. Load testing aims to determine a system's user capacity and find bottlenecks, while stress testing tries to overwhelm resources. Popular open-source tools mentioned include JMeter for web, services, and databases, and Siege for simple command line testing. Other tools and cloud services are also listed, along with example test environments and additional resources.
