You are running a web site that sells trendy designer clothes. At any point in time the average number of concurrent users in your web site is 1,000. You are running the web site on several EC2 servers with Auto Scaling enabled with an application load balancer. You have announced a sale of 70 percent off everything on a certain day. On that day, the moment the sale starts, you notice that the number of concurrent users is exceeding 50,000 in just two minutes, and some users are not able to access the web site. Since you have integrated Auto Scaling, you feel that Auto Scaling should take care of handling all the users. What could be the reason for this?
