This lecture is a ray of light for those who want to experience large-scale traffic but cannot. What on earth is the experience of handling large-scale traffic that is considered important in service companies? Or, you can experience it if you go to a service company, but you need to know it to go to a service company. I think this lecture is suitable for those who think, "What should a newbie like me do?" I think it is better because the lecture is set up so that you can see some functions that are not provided if you follow the current Artillery document. A few days ago, I remember an anecdote where a cell manager of a certain company was so well-versed in legacy that he gathered his team members and said, "Now, press F5 to refresh!" and said, "Let's do a traffic test!" I recommend this lecture because I think it can encompass even experienced people who do not have the concept of stress testing.
