Scenario:
During some festival season days some eCommerce website(php based) has flash sales,at that day they will get a huge number of traffic compared to other off season days.
for e.g : Suppose if the website has 10k visitor/day and on flash sale day they have 100k visitors.
In this case how will we manage the website traffic without affecting the site performance and working? Is there any technique to handle the huge number of users per day without website breaking? Kindly explain the answers.
