Using Selenium, Docker, and Cloud for Performance Testing

Growing up in performance engineering in the last decade, it was almost impossible to think of simulating load using a real browser because a performance engineer would need a lot of machines to simulate load using a real browser. Performance engineers used to have a couple of desktop or servers to simulate hundreds and thousands of users load. Their preferred choice used to be to capture HTTP/s requests using tools like LoadRunner, JMeter, Soasta, and Neoload.

An application with custom protocol, proprietary security features, or dynamic webpage content used to pose a great challenge for performance engineering. Traditionally, performance engineers will use tools like load runner's click/web or RTE protocols or tools like Apploader to deal with such an application.
