A customer has a website which shows all the sales available in leading online and brick-and-mortar stores.

Currently, the website's web, application, and database tiers are hosted on five large, on-demand EC2 instances to manage day-to-day traffic. However, from late November through the end of December, the website traffic quadruples the normal rate for various periods, sometimes a few minutes, and sometimes a few hours. During the peaks in activity, the website requires up to 20 large instances.

The level of activity is not predictable. It is also prone to large, sudden spikes at random times based on when various temporary sales are available. The site's traffic can quadruple in a matter of minutes.

Which option is the most cost-effective and achieves better performance to handle these peaks in traffic reliably?
